How to Stay Healthy and Boost Your Immunity: 7 Habits to Follow

How to Stay Healthy and Never Get Sick: 7 Science-Backed Habits to Boost Your Immunity

1. Regular Exercise

One of the best ways to strengthen your immune system is to exercise regularly. Exercise improves your blood circulation, which helps deliver oxygen and nutrients to your cells and organs. It also reduces inflammation, which can lower your risk of infections and chronic diseases. Exercise can also enhance your mood, energy, and mental health.

You don’t have to do intense workouts to reap the benefits of exercise. Even moderate activities like brisk walking, cycling, or yoga can be beneficial. The World Health Organization recommends that adults do at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity aerobic exercise per week. You can also do some strength training exercises to build your muscles and bones.

2. Balanced Diet

Another key factor for your immune health is your diet. What you eat can affect your immune system’s ability to fight off germs and diseases. A balanced diet that includes a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats can provide you with essential nutrients that support your immune function. Some of these nutrients are vitamins C and D, zinc, and antioxidants.

Vitamin C is a powerful antioxidant that can help protect your cells from damage and boost your immune response. You can find vitamin C in citrus fruits, berries, peppers, broccoli, and other fruits and vegetables. Vitamin D is a hormone that can help regulate your immune system and prevent infections. You can get vitamin D from sunlight exposure, fortified foods, or supplements. Zinc is a mineral that can help your immune cells function properly and heal wounds. You can get zinc from meat, seafood, nuts, seeds, and legumes. Antioxidants are compounds that can help prevent or reduce oxidative stress, which can damage your cells and weaken your immunity. You can get antioxidants from colorful fruits and vegetables, green tea, dark chocolate, and spices.

3. Adequate Sleep

Sleep is not only important for your brain and body, but also for your immune system. When you sleep, your body produces and releases cytokines, which are proteins that can help fight infections and inflammation. Lack of sleep can reduce the production of these cytokines and make you more vulnerable to illness. Sleep can also help your body repair itself and regulate your stress hormones.

Adults should aim for 7-9 hours of quality sleep per night, according to the National Sleep Foundation. To improve your sleep quality, you can follow some tips such as:

  • Stick to a regular sleep schedule and routine.
  • Avoid caffeine, alcohol, nicotine, and heavy meals before bed.
  • Make your bedroom comfortable, dark, quiet, and cool.
  • Avoid using electronic devices at least an hour before bed.
  • Relax your mind and body with meditation, reading, or music.

4. Hydration

Hydration is another essential habit for your health and immunity. Water is the main component of your blood, which carries oxygen and nutrients to your cells and organs. Water also helps your body naturally eliminate toxins and other bacteria that may cause illness. Water can also improve your digestion, skin, and brain function.

The amount of water you need depends on your age, weight, activity level, and climate. A general rule of thumb is to drink at least eight glasses of water per day, or more if you are active or sweat a lot. You can also get water from other sources such as fruits, vegetables, soups, juices, and herbal teas. However, you should avoid or limit drinks that can dehydrate you, such as soda, coffee, alcohol, and energy drinks.

5. Stress Management

Stress is inevitable in life, but too much stress can harm your health and immunity. Chronic stress can weaken your immune system, making you more susceptible to illness. Stress can also affect your mood, appetite, sleep, and blood pressure. Therefore, it is important to manage your stress levels and cope with it in healthy ways.

Some of the stress management techniques that can help you are:

  • Meditation: Meditation is a practice that involves focusing your attention on your breath, a word, a sound, or an object. It can help you calm your mind, relax your body, and reduce your stress. You can try different types of meditation, such as mindfulness, transcendental, or guided meditation.
  • Deep Breathing: Deep breathing is a simple but effective way to lower your stress and anxiety. It can help you slow down your heart rate, lower your blood pressure, and relax your muscles. You can practice deep breathing by inhaling deeply through your nose, filling your lungs with air, and exhaling slowly through your mouth.
  • Hobbies: Hobbies are activities that you enjoy doing and that make you happy. They can help you distract yourself from your worries, express yourself creatively, and have fun. You can choose any hobby that suits your personality and interests, such as gardening, painting, knitting, playing an instrument, or cooking.

6. Good Hygiene

Good hygiene is a basic but important habit for your health and immunity. Good hygiene can help you prevent or reduce the spread of germs that can cause infections and diseases. Some of the good hygiene practices that you should follow are:

  • Regular hand washing: Hand washing is one of the most effective ways to protect yourself and others from germs. You should wash your hands with soap and water for at least 20 seconds, especially before and after eating, after using the bathroom, after coughing or sneezing, and after touching public surfaces.
  • Good oral hygiene: Oral hygiene is not only important for your teeth and gums, but also for your overall health. Poor oral hygiene can lead to dental problems, bad breath, and infections that can affect your heart, lungs, and brain. You should brush your teeth twice a day, floss daily, and visit your dentist regularly.
  • Keeping living environments clean: Keeping your home, workplace, and other living environments clean can also help you prevent or reduce the exposure to germs. You should regularly clean and disinfect the surfaces that you touch frequently, such as countertops, tables, doorknobs, keyboards, and phones. You should also change your bed sheets, towels, and clothes often, and wash them with hot water and detergent.

7. Avoiding Harmful Habits

Last but not least, avoiding harmful habits is another habit that can help you stay healthy and boost your immunity. Some of the harmful habits that you should avoid or limit are:

  • Smoking: Smoking is one of the worst habits for your health and immunity. Smoking can damage your lungs, increase your risk of cancer, and impair your immune system. Smoking can also make you more prone to respiratory infections, such as colds, flu, and COVID-19. If you are a smoker, you should quit as soon as possible, or seek help from your doctor or a support group.
  • Excessive alcohol consumption: Alcohol consumption can have some benefits in moderation, such as reducing stress and improving heart health. However, excessive alcohol consumption can have negative effects on your health and immunity. Alcohol can dehydrate you, interfere with your sleep, damage your liver, and weaken your immune system. Alcohol can also impair your judgment and increase your risk of accidents and injuries. You should limit your alcohol intake to no more than one drink per day for women and two drinks per day for men, or avoid it altogether if you have a medical condition or take medication.
  • Other harmful substances: Other harmful substances, such as drugs, steroids, or antibiotics, can also harm your health and immunity. These substances can alter your brain chemistry, affect your mood and behavior, and cause addiction and dependence. They can also damage your organs, increase your risk of infections, and reduce your immune response. You should avoid using these substances unless they are prescribed by your doctor and used as directed.


These are the seven habits that can help you stay healthy and boost your immunity. By following these habits, you can improve your physical, mental, and emotional well-being, and reduce your risk of getting sick. However, these habits are not a substitute for medical advice or treatment. If you have any health concerns or symptoms, you should consult your doctor as soon as possible.
