Face and fingerprint ID login is a convenient, seamless way to gain app access on a mobile device. Instead of typing in a lengthy, hard-to-remember username and password, many apps allow you login with just a quick scan of your face or fingerprint (also known as biometrics).

Considerations and Approaches for Implementing Biometric Login: Part 1

It's a desirable feature for both our end user and the Patients Team here at Alto — we want to make it as easy as possible for users to log in while also performing more frequent authentication checks. Improve the user experience and the security of our app? Sounds like a win-win.

As an engineer, implementing biometric login might seem easy, as mobile devices already capture, manage, and encrypt biometric data and expose APIs for app developers like myself to initiate a biometric scan. All I need to do is call that API and wait to hear if the scan is successful or not. What isn't as simple, though, is figuring out what to actually do with a successful biometric scan response. What does a successful scan mean, and how does that relate to the username and password credentials that users currently use to access our app?

This post walks through the decision points we encountered while implementing biometric login and how our healthcare privacy concerns influenced the final implementation approach.

Prior to implementing biometric login, the only way for users to access the Alto app was with email (username) and password. A valid email and password generates a session, which expires at some frequency. Once the session expires, the user must re-enter their email and password to regain access to the app.

From the beginning, we knew that biometrics would need to be built with our existing email and password session management in mind. This is made clear in the Apple developer docs: "Use biometrics as a supplement to something you’re already doing. Don’t depend on biometrics as your only authentication option."

Make it easier for users to login. Nobody likes typing in an email and password — especially on a mobile app. Our goal was to reduce the number of times a user must enter their email and password.

Enhance the security of our app using more frequent authentication checks. As a healthcare app that displays Personal Health Information (PHI), conducting more frequent authorization checks decreases the likelihood of PHI becoming exposed to an unauthorized third party.

Have the ability to revoke biometric access from a particular user. Similarly, we want to be extra careful to ensure that if a device is lost or stolen, we have a fallback plan to invalidate a user's session and protect the user’s PHI. For email and password initiated sessions, this happens when a user changes their password, as any change in login credentials will invalidate all active sessions for that user. We needed a similar contingency plan for biometric login.

There are several ways to use a mobile device's biometrics to authenticate a user, with varying degrees of security.

No server-side authentication. Simply integrate with the device's biometrics as an extra layer of authentication. If the biometric scan is successful, let the user proceed into the app.

Provides an extra check and gives your app a sense of modern polish

No server-side validation means that nothing is being validated against your system, so this is not a good substitute for account authentication. Therefore, even if you add this check, the user should still be prompted to re-enter their email and password at the same frequency as before.

Given this, this approach wouldn't help us reach our goal of reducing the number of times a user must enter their email and password.

This approach is a good fit if your application already has an existing login and session management system, and you want extra authentication checks throughout the user's session without modifying any other part of the system.

Tie biometrics to our existing email and password authentication. Use the user's biometrics to unlock an encrypted version of their email and password credentials. When a user sets up biometric login, store the user's login credentials within the device's keystore — the keystore will automatically encrypt the credentials. After a successful biometric scan, retrieve those credentials from the keystore and send them to your existing login API.

Still easy to implement, no backend changes needed

Biometric scan can be used in place of entering an email and password

Changing email and password credentials will revoke biometric access: if a user changes their credentials, their biometrics will access stale credentials and fail to login. (This is somewhat of a con as well — it provides a poor user experience, but it's an edge case that should happen infrequently.)

There is still only one way for a user to authenticate server-side, but now two ways to pass server-side authentication — essentially weakening your app's existing account security.

This approach effectively hands out internal login credentials to third party storage. While not a huge risk considering a device's secure storage is encrypted and trusted by most users, it’s not necessarily a best practice either.

This approach is a good fit if your application doesn't contain sensitive data, and your goal is to make it more convenient for a user to login by replacing email and password with a biometric scan.

Create a separate authentication mechanism for biometrics. Introduce a new authentication mechanism specifically for biometrics, resulting in two independent forms of server-side session authentication: email with password and biometrics. The implementation could look like generating a keypair or a shared secret to save and validate against the server whenever a user attempts to login with biometrics.

Biometrics is now tied to its own secure server-side authentication mechanism, which means it can be used independently of email/password (or even replace it, if you choose to).

Two layers of authentication adds security to the app. Not only does a user need a valid email/password session, they also need a valid biometric session.

It provides fine-grain control over a user's biometric session. You can invalidate a user's biometric session by invalidating the public key and can even invalidate a biometric session without impacting an email-and-password session if needed.

Requires building and maintaining a separate authentication mechanism

This approach is a good fit if your application contains sensitive data (e.g. PHI or financial information), and your goals are to make it both more convenient for a user to login by replacing email and password with a biometric scan while also strengthening the security of your account management system.

Because we are a healthcare company dealing with sensitive data, we chose this last path. It required greater engineering investment, but we agreed it was imperative that we maintain a secure system while introducing biometric login for users.

While HIV and AIDS remain urgent public health issues, the prevention and treatment landscape has transformed drastically throughout the past four decades. Breakthroughs in treatment have made it possible to stop the progression of HIV and prevent transmission of the virus to others. Read on to learn more about HIV stages, symptoms, treatment, and prevention.

All About HIV: Stages, Symptoms and Treatment

More than 40 years have passed since AIDS, the disease caused by HIV, was first identified in the United States. While HIV and AIDS remain urgent public health issues, the prevention and treatment landscape has transformed drastically throughout the past four decades. Breakthroughs in treatment have made it possible to stop the progression of HIV and prevent transmission of the virus to others. Read on to learn more about HIV stages, symptoms, treatment, and prevention.

HIV (human immunodeficiency virus) is a virus that attacks your immune system, making you more vulnerable to other illnesses. It is transmitted through contact with the blood, semen, or vaginal fluids of someone who has HIV.

If untreated, HIV can lead to AIDS (acquired immunodeficiency syndrome), which is also considered the last stage of HIV. When HIV progresses into AIDS, your immune system has been significantly weakened by the virus.

Currently, there is no cure for HIV, but taking HIV medicine called antiretroviral therapy (ART) as prescribed stops the progression of the disease. As a result, most people living with HIV in the U.S. do not develop AIDS. There are also HIV prevention medications, PrEP and PEP, which are effective at preventing the transmission of HIV through sex or intravenous drug use.

As the HIV epidemic emerged in the U.S. in the 1980s and 90s, gay and bisexual men were disproportionately affected — in part because the virus transmits more easily through anal sex than vaginal sex — and subsequently stigmatized as carriers of the virus. However, the medical community soon discovered that anyone can contract HIV regardless of gender identity or sexual orientation, as the virus can be transmitted through anal sex, vaginal sex, or the sharing intravenous drug equipment such as needles or syringes.

In recent years, there has been significant progress toward reducing the annual HIV infection rate, and new cases of HIV among gay and bisexual men ages 13-24 dropped by 33% between 2015-2019. Still, gay and bisexual men accounted for 69% of all new HIV diagnoses in the U.S. in 2019. And in recent years, Black and Latinx individuals have been disproportionately affected by HIV. Racial and ethnic discrimination and disparities in healthcare access — which can discourage people from seeking HIV prevention services and testing — factor into HIV’s outsized impact on these communities.

There are three primary stages of HIV: acute HIV infection, chronic HIV infection, and stage 3 HIV, or AIDS.

Acute HIV infection, the first stage of HIV, may develop within two to four weeks of contracting the virus. During this stage of HIV, the virus multiplies rapidly and there is a high amount of HIV in your bloodstream (also known as your viral load). While the virus replicates and spreads, it destroys your CD4 cells, a type of white blood cell that plays a role in your immune system.

Some people with acute HIV infection quickly experience flu-like symptoms including fever, chills, rash, night sweats, muscle aches, sore throat, fatigue, swollen lymph nodes, and mouth ulcers. The only way to know your HIV status is by getting tested. If you have any of these symptoms and believe you may have been exposed to HIV, seek prompt medical care and take an HIV test. Find a free and confidential HIV testing site near you..

Experiencing these symptoms does not necessarily mean that you have HIV, as they overlap with symptoms of the flu and other illnesses. And some individuals with HIV develop these symptoms later, while others never develop them at all, which is why it’s critical to get tested for HIV on a regular basis — ideally every three months. You can still transmit the virus to others even if you do not have noticeable symptoms of HIV.

During the chronic HIV infection stage, the virus replicates less rapidly than it did in the acute stage, but it continues to damage your CD4 cells and weaken your immune system.

Many people experience no symptoms or mild symptoms during this latent period, which is also sometimes referred to as asymptomatic HIV infection or clinical latency. However, just like during the acute HIV infection stage, you can still transmit the virus to others even if you are not experiencing symptoms.

Without effective treatment, your viral load will increase and your CD4 cell count will decrease as this stage of HIV progresses. You are more likely to experience symptoms of HIV when your viral load is high and your CD4 cell count is low. Taking HIV medication as prescribed can help you maintain a low or even undetectable viral load and prevent your HIV from progressing into AIDS.

AIDS is the third and most advanced stage of HIV. In this stage, your immune system is severely weakened, your viral load continues to increase, and your CD4 cell count continues to decrease. 

HIV progresses into AIDS when you have a CD4 cell count of less than 200 cells per cubic milliliter or when you develop an opportunistic infection (OI), an illness that occurs more frequently in individuals with HIV because of their weakened immune systems.

Opportunistic infections experienced by individuals with HIV include kaposi’s sarcoma, a type of cancer that develops in your blood and lymph vessels; pneumocystis pneumonia (PCP), and mycobacterium avium complex (MAC), tuberculosis-related bacteria. However, OIs continue to occur less frequently as HIV treatment becomes more effective.

There are many effective HIV treatment options that can keep you healthy and help you maintain a low viral load. The primary treatment for HIV is called antiretroviral therapy (ART), a combination of medications that lower the amount of HIV in your bloodstream.

If you take your HIV medication every day as prescribed, you can maintain an undetectable viral load. This will preserve the strength of your own immune system and prevent you from transmitting the virus to others.

Starting ART as soon as possible after you receive an HIV diagnosis is critical to lowering your risk of developing AIDS and preventing you from transmitting the virus to others. If you have tested positive for HIV, reach out to your healthcare provider right away to begin treatment.

If you have tested negative for HIV, there are important HIV prevention medications that can help you continue to protect your health: PrEP and PEP.

PrEP, or pre-exposure prophylaxis, can lower risk of sexual transmission of HIV by 99% when taken daily and reduces the risk of getting HIV from intravenous drug use by about 74%. PrEP may be right for you if you have a partner who is HIV-positive or unsure of their HIV status, or if you have multiple partners. Pharmacists in a growing number of states can now prescribe PrEP.

PEP, or post-exposure prophylaxis, is a medication taken within 72 hours of potential exposure to HIV to lower your chances of contracting the virus. It can be prescribed by a healthcare provider at emergency rooms, sexual health clinics, community-based health centers, and, in some states, pharmacies. PEP is only for emergencies and accidental exposures. If you anticipate ongoing risk of exposure to HIV, speak with your doctor about potentially taking PrEP for long-term protection.

Celebrating National ERG Day at Alto

The history of employee resource groups (ERGs) in the U.S. dates back to the 1960s, when a group of Black employees at Xerox self-organized to discuss their experiences of workplace discrimination and advocate for more inclusive policies. At the time, these networks of employees united by a shared identity or experience were known as affinity groups.

Today, ERGs can be found at companies of all sizes and industries where they play an important role in shaping an inclusive culture and fostering a sense of belonging in the workplace. In honor of National ERG Day, which falls on November 17 every year, we’re highlighting the important work of Alto’s six ERGs. 

At Alto, we believe that every perspective matters, and that diversity fosters creativity and leads to innovation. Our six ERGs are part of our broader commitment to diversity, equity, and inclusion (DEI), both in creating our company culture and delivering an exceptional pharmacy experience.

"At Alto, we’re committed to building and sustaining an inclusive workplace that both supports our employees and helps us deliver on our mission to improve the quality of life for everyone who needs medicine,” shared Ty Bledsoe, Head of Diversity, Equity & Inclusion. “Our ERGs help foster authentic relationships, offer safe spaces for education and conversation, and celebrate the incredible diversity of our Altoids and our communities."

By building community, providing support, and contributing to an individual’s personal and professional well-being, these groups help ensure that every Altoid feels a sense of belonging each day at work and that we appreciate the diversity of the customers we serve.

Here are just a few ways that each Alto ERG contributes to a more inclusive culture and pharmacy experience.

Umoja’s mission is to inform, educate, and empower Black Altoids and allies. The group has deepened Altoids’ understanding of the Black experience by sharing educational resources in support of Black History Month, Juneteenth, and Pride.

They also help our team explore the intersection of identity and healthcare as it relates to our services. After Dr. Reverend Stacey Edwards, founder of Fertility for Colored Girls, spoke at Alto about the fertility journeys of Black families this spring, Umoja continued the conversation by inviting Dr. Temeka Zore, OB GYN and reproductive endocrinologist at Spring Fertility, and Esther Ebeuhi, a licensed doula and birth equity analyst, to speak on Black motherhood.

Alto Auténtico aims to build community among Latinx Altoids and ensure that they have a voice at Alto. In addition to facilitating company-wide learning about the Latinx experience and the diversity within Latinx culture, Alto Auténtico’s mentorship program connects junior and senior Latinx team members for coaching sessions and professional development. The group is also working with Alto’s operations, product, and marketing teams to establish a bilingual team to better support Spanish-speaking individuals using our pharmacy services across our communities.

Proud unites LGBTQ+ Altoids and allies in creating an environment where all Altoids can be their most authentic selves. The group has led Alto in celebrating important LGBTQ+ awareness days with events such as drag queen bingo nights for Pride and LGBTQ+ history month. Two Proud members who identify as bisexual gave a talk for Bi Visibility Day on September 23 and also shared their experiences of coming out in in observance of National Coming Out Day on October 11.

Proud also invites experts to speak at Alto about a range of LGBTQ+ issues. They recently hosted a session with Chris Tompkins, author of Raising LGBTQ Allies: A Parent’s Guide to Changing the Message from the Playground, and a fireside chat with Dr. Lisa Capaldini, who has focused on HIV since the beginning of the epidemic.

Women of Alto + Allies (WOAA) helps create an inclusive community for women at Alto with mentorship and networking opportunities that advance their leadership potential. Their newly launched initiative, WOAA Project Spotlight, celebrates female-identifying team members who have helped us deliver on our mission while living our values, and a quarterly webinar series shares how various self-identifying Altoid women launched their careers.

Working Parents + Allies facilitates discussion and collaboration in celebration of our working parents. The ERG has led Alto in supporting working parents with a variety of initiatives, including a community event with the Kids & Art Foundation’s Purvi Shah in honor of Bereaved Parents Month this July; an “Ask a Parent Anything” Slack advice hotline for parents, caretakers, and allies; and free access to Outschool’s live online classes for kids ages 3-18.

And with their second annual Holiday Giveback Program, which donates gifts to kids and families in need through Marine Toys for Tots and the Boys & Girls Club of America, Working Parents + Allies is an example of how our ERGs look for opportunities to give back and show support beyond the immediate Alto community.

During Asian American Pacific Islander month, the Asians ERG shared resources for individuals like Modern Health's Healing Asian Communities Circles and highlighted community groups for volunteerism and donations.

A consistent lack of sleep can also affect your physical and mental health in the long term. Here's what you can do to improve your sleep hygiene.

How Sleep Affects Heart Health | Alto Pharmacy

If you’ve ever slept less than the CDC-recommended minimum of seven hours per night, you may have experienced short-term effects of sleep deprivation like forgetfulness, irritability, and an inability to focus. A consistent lack of sleep can also affect your physical and mental health in the long term. And just like diet choices and frequency of physical activity, your sleep habits are linked to your risk for heart disease.

Below, we explain more about how sleep affects heart health and what you can do to improve your sleep hygiene.

Sleep allows your body to recharge. As you enter a state of deep sleep, your heart rate slows down and your blood pressure drops. These physical changes give your heart a chance to recover from how hard it works when you’re awake.

When you don’t spend enough time in uninterrupted deep sleep, your heart doesn’t get the opportunity to rest. Research has found that chronic sleep deprivation and sleep disorders can contribute to numerous cardiovascular health issues including high blood pressure, high cholesterol, and a greater risk for a heart attack or stroke.

Cardiovascular health issues related to sleep

Over time, many sleepless nights can lead to higher baseline blood pressure levels during the day. High blood pressure, or hypertension, is among the leading risk factors for heart disease and stroke. If you experience consistent stress or if you have other risk factors for high blood pressure, you may be more likely to develop high blood pressure as a result of sleep deprivation.

Poor sleep may also contribute to these cardiovascular health issues:

Coronary artery disease occurs when cholesterol and other fatty material (collectively referred to as plaque) builds up in your arteries, making it harder for your heart to pump blood to the rest of your body. This accumulation of plaque is also called atherosclerosis.

Some research has found that a lack of sleep may contribute to atherosclerosis. This is partially due to the connection between sleep deprivation and hypertension, as high blood pressure strains your arteries. In addition, poor sleep can trigger chronic inflammation over time, which also contributes to the accumulation of plaque and the hardening of your arteries.

Chronic sleep deprivation may also increase your risk for a heart attack. One research study found that people who slept less than six hours per night had a 20% higher risk of a heart attack in comparison to those who got more sleep.

While your heart slows down when you are in a state of deep sleep, your heart rate and blood pressure can increase if you wake up suddenly. Over time, consistent sleep disruptions can put greater stress on your heart and contribute to your overall heart attack risk.

A stroke is a cardiac event in which blood flow to your brain is interrupted, causing brain cells to die. Because sleep deprivation can drive high blood pressure and plaque accumulation in your arteries — two leading risk factors for strokes — there is also a correlation between a lack of sleep and your risk of having a stroke.

Type 2 diabetes is a condition in which your body’s cells become resistant to insulin, and your pancreas cannot produce enough insulin to regulate levels of blood glucose. It develops gradually due to a mix of genetic, lifestyle, and environmental factors.

Research has linked poor sleep to prediabetes, a health condition defined primarily by blood sugar levels that are higher than normal but below the official range for a type 2 diabetes diagnosis. If left untreated, prediabetes can progress into type 2 diabetes and lead to health complications in the long term, including cardiovascular issues.

If you already have diabetes, a lack of sleep or frequently interrupted sleep may also impact blood sugar management.

There are two primary sleep problems that can impact your long-term cardiovascular health: sleep apnea and insomnia.

Sleep apnea is a disorder in which your airway is blocked during sleep, which causes you to stop breathing for short periods of time. It affects your oxygen levels while sleeping and may increase your risk for high blood pressure, heart attack, and stroke.

Insomnia is when you have trouble going to sleep or staying asleep. Many individuals have experienced insomnia in the short-term, and the CDC estimates that 1 in 10 U.S. adults may experience chronic insomnia.

More than 1 in 3 adults in the U.S. report getting less than the recommended seven hours of sleep per night. The good news is there are steps you can take to improve your sleep hygiene. Start with the following:

Maintain a consistent sleep schedule, going to bed and waking up at the same time every day, including weekends.

Avoid use of electronic devices close to your bedtime.

Get plenty of natural light and stay physically active during the day, but avoid exercising close to bedtime.

Avoid consuming food or beverages close to bedtime, particularly caffeine, alcohol, and high-sugar or high-fat foods.

Keep your bedroom dark and quiet and maintain a comfortable temperature. 

Read our previous blog for strategies that can help you avoid stress-related sleep problems..

If you think you may have a sleep disorder, you should also consult with your doctor for a diagnosis and treatment, in addition to taking the actions above.

At Alto, we’re committed to making it as simple as possible to protect your heart health and stay on top of cholesterol-lowering or blood pressure management medications.  We will work with your doctor, your insurance (if applicable), and any third party savings programs that you may qualify for to ensure your medications are as affordable as possible. And our team of pharmacists is available to chat whenever questions come up about side effects or how to take your medication properly

How Sleep Affects Heart Health & Tips for Better Sleep

We’re excited to welcome Ramiah Martin to Alto as Vice President, Operations & Supply Chain. Here’s more on what drew him to Alto and the opportunities he’s most excited about, in his own words. 

Meet Ramiah Martin, VP, Operations & Supply Chain

We’re excited to welcome Ramiah Martin to Alto as Vice President, Operations & Supply Chain. Prior to joining Alto, Ramiah was Senior Director of Operations at Amazon, where he developed the strategic vision for the company’s operations and led a cross-functional team in implementing new processes and technologies to streamline use of resources.

His dedication to continually improving the customer experience is matched by a passion for healthcare change, and we could not be more thrilled to have Ramiah on the team. Here’s more on what drew him to Alto and the opportunities he’s most excited about, in his own words. 

Welcome to Alto! What inspired you to join the team?

When I first learned about Alto, its mission and values stood out to me first and foremost. I immediately felt a strong connection with the company’s mission of improving the quality of people’s lives through medicine and its commitment to putting customers first.

I was compelled by the opportunity to truly make a positive impact and help transform an industry that is both in need of improvement and slow to evolve. Through my previous experiences in operations management at Amazon and UPS, I know that streamlined processes can have a massive impact on a company’s results. At Alto, all of those efforts to innovate and maximize efficiency are in the service of driving broader change within pharmacy and healthcare.

I also appreciated that Alto is intentional about investing in talent representative of the communities we serve. As we continue to grow, and our customer base diversifies, it’s critical to have that diversity represented in the people building our new model for pharmacy care.

What is the focus of your role and what opportunities are you excited about?

As Vice President of Operations & Supply Chain, I’m focused on creating a scalable and sustainable organization, ensuring that as we grow, we continue to deliver an exceptional experience for our customers.

We have a great opportunity to ensure that individuals who have been historically underserved by medicine receive the standard of care that they deserve. I believe in the product — we make it as simple as possible to manage your health and learn more about medication and pricing, and our customers’ medication adherence rates are far above industry standards. I know there’s a lot more we can accomplish, and it’s a privilege to lead a team that’s united by a bold vision for healthcare.

I love movies, except for horror (Michael Jackson's “Thriller” video and Children of the Corn scarred me). I will go to the movies by myself as long as I have my Cherry Coke. It’s my way of shutting off my brain for an hour or two and relaxing.

You can find more information about Ramiah or connect with him directly on LinkedIn. If you have any questions about Alto, or are interested in joining our team, please visit alto.com/careers.

From vigilant hand-washing to getting enough vitamin C and D, here are a few ways to give yourself an immunity boost in advance of cold and flu season.

How to Prepare for Cold and Flu Season

The leaves are turning and the days are getting shorter, which means it’s time to start preparing for cold and flu season. The flu — shorthand for influenza — is a respiratory illness caused by viruses that affect your nose, throat, and lungs. In the U.S. and the rest of the Northern Hemisphere, flu cases typically ramp up toward the end of October and peak between December and February.

One reason the flu spreads more easily during the winter months is that cold air protects the virus as it travels through the air in the form of tiny droplets. The other main reason is that people socialize indoors more frequently, where it’s easier for the flu to spread when someone affected by the virus coughs or sneezes.

The good news is that there are simple steps you can take to strengthen your immunity. From vigilant hand-washing to getting enough vitamin C and D, here are a few ways to give yourself an immunity boost in advance of cold and flu season.

The number one thing you can do to protect your health and that of your loved ones is to get an annual flu shot, which will prompt your immune system to create antibodies that will defend you against the flu. Medical experts recommend getting the vaccine each and every year. every year.

Keep in mind it can take up to two weeks for the antibodies to provide sufficient protection. Given that flu season often peaks around December, the best time to get vaccinated is during September and October, and ideally no later than the end of October.

The flu can cause more serious health problems for people over the age of 65 and individuals living with chronic conditions such as COPD or diabetes, so it’s even more important to be proactive about flu vaccination if you fall into one of these groups.

Good personal hygiene can lower your risk of getting the cold or flu and spreading it to others. Practice simple preventative measures like frequently washing your hands, disinfecting frequently touched surfaces, and keeping a healthy distance from anyone who isn’t feeling well.

And yes, there is a “right way” to wash your hands when it comes to cold and flu prevention. The CDC recommends following the simple steps below to stay healthy and avoid spreading germs.

1. Wet your hands with warm or cold running water and apply soap.

2. Lather your hands, including the backs of your hands, between your fingers, and beneath your nails. 

3. Scrub your hands for at least 20 seconds. (Singing “Happy Birthday” twice is one option for timing yourself.)

Get a good night’s sleep and regular exercise

Your body is better prepared to defend against infectious diseases when it’s well-rested. Research has found that sleep can strengthen your T cells’ ability to help you fight infection. (T cells are a specific type of white blood cell and an important part of your immune system.)

To strengthen your immunity, aim for 7 to 9 hours every night. If you’re having difficulty falling asleep or sleeping through the night, there are some steps you can take to improve the quality of your sleep. Try to follow a consistent schedule: go to bed at the same time each night and wake up at the same time each morning, even on the weekends. And avoid consuming heavy meals or caffeine or using electronic devices close to your bedtime.

Staying physically active can also help you sleep better. In fact, exercise may boost your immunity in other ways, too, such as increasing your circulation, which helps white blood cells and antibodies travel to parts of your body where they’re needed. 

Studies have found that U.S. adults tend to exercise less during winter and fall than they do during spring and summer, so be sure that your calendar can still accommodate your fitness routine during the colder months. Whether you explore virtual workout classes or bundle up to brave the cold, aim for about 150 minutes of exercise a week or 30 minutes per day.

Your dietary choices can strengthen your immune system, not only during cold and flu season but all year round. 

Probiotics are tiny organisms that can help you maintain a healthy balance of bacteria in your digestive system, which will also support your immune system. Fermented foods like kimchi, sauerkraut, and kefir all contain live probiotics, as does greek yogurt. In addition, legumes like chickpeas and lentils contain prebiotics, a type of fiber consumed by probiotics which also contributes to a healthy digestive system.

Oranges, tomatoes, and spinach each offer up plenty of Vitamin C, a powerful nutrient with many health benefits, including the ability to boost immunity and fight inflammation.

You’re automatically exposed to Vitamin D — another crucial immunity-related nutrient — on hot, sunny days, but during winter, it’s extra important to add it to your diet. Sources of Vitamin D include egg yolks, mushrooms, canned tuna, and salmon, which also contains other immunity-boosting nutrients like zinc and omega-3 fatty acids. There is evidence that taking Vitamin D daily can significantly lower your risk of getting sick with the cold or flu, and you may also consider taking Vitamin D supplements.

Lastly, if you’re feeling under the weather, be sure to drink 6-8 cups of water a day, as you can become dehydrated more easily when sick.

When you’re chronically stressed, your body releases a hormone called cortisol very frequently. Cortisol helps the body fight inflammation and infection, but its continual release can lessen its effectiveness as part of your immune system.
