The Secrets of People Who Never Get Sick

Have you ever wondered how some people always seem to stay healthy, even during cold and flu season? What makes them so strong against sickness? Today, we’re going to talk about some of the secrets these people know—habits that keep their immune systems strong. According to Dr. Iroko Anita, a certified medical doctor, these tips are simple but very effective.

They Eat Healthy Foods to Keep Their Immune System Strong

One of the main secrets of people who rarely get sick is the food they eat. They aren’t just eating to feel full—they’re eating to give their bodies the nutrients they need. Dr. Anita explains that a diet full of fruits (like berries and citrus fruits), vegetables (such as spinach and broccoli), whole grains (like oats and quinoa), lean proteins (such as chicken and fish), and healthy fats (like avocados and nuts) is important for keeping the immune system strong. These foods have vitamins, minerals, and antioxidants that help fight infections and keep the body healthy.

For example, vitamin C in citrus fruits, beta-carotene in carrots, and zinc in nuts are nutrients that help boost the immune system. Eating lots of different colorful fruits and vegetables makes sure your body gets all the nutrients it needs to stay healthy. Dr. Anita points out that people who focus on eating well are giving their bodies the best chance to stay strong and fight off sickness.

They Exercise Regularly, But Not Too Much

You don’t have to run marathons or lift heavy weights to stay healthy, but being active is something that people who rarely get sick have in common. Exercise helps improve blood flow, lowers stress, and boosts the immune system. Dr. Anita advises doing moderate exercise—like brisk walking, dancing, gardening, cycling, or swimming for about 30 minutes most days of the week—to keep your immune system strong.

But over-exercising can actually make your immune system weaker. If you push your body too hard without enough rest, you can get tired and stressed, which makes it easier to get sick. The key, as Dr. Anita emphasizes, is balance—enough exercise to stay fit, but not so much that it leaves you feeling worn out.

They Get Enough Sleep So Their Body Can Rest and Heal

Sleep is super important for keeping your immune system healthy. People who rarely get sick know that getting enough good sleep is key. Dr. Anita says that when you sleep, your body goes through important repair processes and makes cytokines—proteins that help fight infections and inflammation. If you don’t get enough sleep, your body can’t do these things well, and you might get sick more easily.

Adults should try to get 7-9 hours of sleep each night. This amount of sleep helps the body repair itself, supports immune function, and keeps energy levels steady. It’s not just about how much sleep you get, but also how good the sleep is. Having a regular bedtime, making sure your bedroom is comfortable, and avoiding screens before bed are good ways to get restful sleep. When you get good sleep, your immune system works better, which helps keep you healthy.

They Manage Stress Because Too Much Stress Weakens Their Immune System

Chronic stress is bad for your immune system. When you are stressed for a long time, your body makes cortisol, a hormone that, in high amounts, can weaken your immune system. People who rarely get sick have found ways to manage their stress. Dr. Anita suggests that things like meditation, yoga, and deep breathing can help reduce stress and keep the immune system strong.

They also know that having a support system is important. Talking to friends and family or getting professional help when feeling overwhelmed can help lower stress. Dr. Anita encourages everyone to find what works best for them to manage stress, whether it’s physical activity, creative hobbies, or just taking a break when needed.

They Practice Good Hygiene to Avoid Getting Sick

Good hygiene is another habit that helps people stay healthy by staying away from germs, which is one of the best ways to avoid getting sick. Dr. Anita says that washing your hands often with soap and water—especially before eating, after using the bathroom, or after being in public—is very important. Washing your hands for at least 20 seconds helps get rid of germs that could make you sick.

They also avoid touching their eyes, nose, and mouth because these are the easiest places for germs to get into the body. Other good hygiene habits, like keeping surfaces clean and covering coughs and sneezes, also help prevent sickness.

They Drink Plenty of Water Because Dehydration Can Weaken the Immune System

Staying hydrated is very important for keeping your immune system healthy. People who rarely get sick make sure to drink enough water every day. Dr. Anita says that water helps carry nutrients to cells, flush out toxins, and keep the body’s mucous membranes moist—which helps fight infections.

Everyone needs a different amount of water, but aiming for about 8 glasses of water per day is a good goal. Some people may need more if they are very active or live in a hot climate. Staying hydrated helps your immune system work well, which helps keep you from getting sick.

They Spend Time Outside to Get Vitamin D for Their Immune System

People who rarely get sick often spend time outside, getting sunlight that provides vitamin D. Vitamin D is important for a healthy immune system, and not getting enough of it can make you more likely to get sick. Dr. Anita suggests spending about 15-30 minutes in the sun a few times a week to help get enough vitamin D.

You can also get vitamin D from foods like fatty fish, egg yolks, and fortified milk. If you can’t get enough from sunlight and food, Dr. Anita says you might need to take a vitamin D supplement after talking to your doctor.

They Don’t Smoke and Limit Alcohol to Keep Their Immune System Strong

It’s well known that smoking and drinking too much alcohol can weaken your immune system. People who rarely get sick usually avoid these habits. Smoking hurts your lungs and makes it harder for your body to fight infections. Drinking too much alcohol can make it harder for your immune system to work well.

Dr. Anita recommends not smoking at all and keeping alcohol to a minimum—up to one drink per day for women and two for men. Avoiding smoking and limiting alcohol helps keep your immune system strong and ready to fight off germs.

They Stay Connected With Loved Ones to Stay Healthy

It might be surprising, but social connections can actually make your immune system stronger. Dr. Anita says that people who have positive relationships and a strong social network tend to be healthier and get sick less often. Being around friends and family can lower stress, increase happiness, and even improve your immune system.

Whether it’s spending time with friends, talking to family, or being part of community activities, staying connected helps keep you happy and healthy. Having people to support you is not just good for your mental health—it also helps your physical health.

They Pay Attention to Their Body and Take Action When They Don’t Feel Well

People who rarely get sick pay attention to how their body feels. Dr. Anita says it’s important to notice when you’re feeling tired, have unusual aches, or have other symptoms that could mean you’re getting sick. These people rest, drink water, and take care of themselves as soon as they feel something is wrong, which helps prevent bigger health problems.

They also don’t wait to get medical advice when they need it. Catching a sickness early makes it easier to treat and helps prevent complications. Dr. Anita encourages everyone to take care of their health and not ignore symptoms that could be warning signs.

The Takeaway

Staying healthy isn’t magic—it’s about building habits that keep your immune system strong. Eating well, exercising, getting enough sleep, and managing stress are all simple habits that help people stay healthy. Start with small, consistent steps, and over time, these habits will become a natural part of your daily life. By adding these habits to your daily routine, you can make your immune system stronger and have a better chance of staying healthy all year.
