Staying healthy is important, especially as we get older. Many people over 30 worry about getting sick more often, feeling tired, or not having enough energy. You might wonder, “How can I help my body fight off germs and feel stronger?” Good news: there are simple, natural ways to help your immune system work better!
Below, we share easy, proven tips to boost your immune system. All advice comes from trusted experts like the CDC, WebMD, Healthline, and Dr. Anthony Fauci.
1. Eat More Fruits and Vegetables
Eating healthy foods is one of the best ways to help your immune system. Fruits and vegetables have vitamins, minerals, and fiber your body needs to stay strong.
- Try to eat many colors: green, red, orange, and yellow.
- Citrus fruits like oranges and grapefruit are great for vitamin C.
- Leafy greens like spinach and kale are full of vitamins.
Why it matters: The CDC says that eating a diet rich in fruits and vegetables helps your immune system fight off sickness (CDC, 2023).
2. Get Enough Sleep
Adults need 7-9 hours of sleep each night. Good sleep helps your body repair itself and keeps your immune system strong.
- Go to bed and wake up at the same time every day.
- Turn off screens at least 30 minutes before bed.
Why it matters: Dr. Anthony Fauci says, “Sleep is a key part of a healthy immune system. Without enough sleep, your body has a harder time fighting off illness” (NIH News, 2020).
3. Move Your Body Every Day
Exercise is good for your heart, your mood, and your immune system.
- Try to walk, stretch, or do light exercise for at least 30 minutes most days.
- You don’t have to run or go to the gym. Even a daily walk helps.
Why it matters: WebMD says that regular exercise helps your immune cells move through your body and work better (WebMD, 2024).
4. Manage Stress
Long-term stress can make you sick more often. Stress makes it harder for your body to fight off germs.
- Try deep breathing, gentle yoga, or listening to music.
- Spend time with friends or family.
Why it matters: Healthline says that learning to relax and manage stress helps your immune system stay strong (Healthline, 2023).
5. Wash Your Hands Often
Washing your hands is a simple way to stop germs from getting into your body.
- Wash with soap and water for at least 20 seconds.
- Clean your hands after you come home, before you eat, and after using the bathroom.
Why it matters: The CDC says handwashing is one of the best ways to stay healthy (CDC, 2023).
6. Avoid Smoking and Limit Alcohol
Smoking and too much alcohol make it harder for your immune system to fight off illness.
- If you smoke, talk to your doctor about ways to quit.
- Try to limit alcohol to one drink a day for women, two for men.
Why it matters: CDC experts say that not smoking and drinking less alcohol lowers your risk of getting sick (CDC, 2023).
7. Consider Natural Helpers
Some people use natural products, like essential oils or nasal sticks, to help them feel better. While these can’t replace healthy habits, they may help you relax or breathe easier. Always check with your doctor before trying new products.
8. Stay Up-to-Date with Vaccines
Vaccines train your immune system to fight certain germs. Ask your doctor about recommended vaccines for adults, like the flu shot or COVID-19 booster.
Why it matters: Dr. Fauci and the CDC say vaccines are safe and help protect you and your community (CDC, 2024).
