Think of your immune system as your body’s protective shield: It’s a wildly intricate system of cells, tissues, and organs that work together to keep you safe from bacteria, viruses, and other potential bad guys that can make you sick. So it only makes sense that you’d want to do everything you can to keep it in good shape during the thick of cold and flu season—especially if you live with a chronic condition (say, an autoimmune disease or immunodeficiency disease) that affects your body’s ability to fight germs.
While there is no magic pill or secret formula to boost your immune system overnight, there are several evidence-based strategies that can support its overall function. Here are some legit ways recommended by doctors to support your immune system:
1. Eat a Balanced Diet
One of the most important ways to support your immune system is by consuming a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. These foods provide essential nutrients, vitamins, and minerals that are necessary for the proper functioning of your immune system.
2. Stay Hydrated
Drinking enough water is crucial for maintaining a healthy immune system. Water helps to flush out toxins from your body and keeps your mucous membranes moist, which acts as a barrier against pathogens. Aim to drink at least 8 glasses of water per day.
3. Get Sufficient Sleep
Adequate sleep is essential for a strong immune system. During sleep, your body repairs and rejuvenates itself, including your immune system. Aim for 7-9 hours of quality sleep each night to support optimal immune function.
4. Manage Stress Levels
Chronic stress can weaken your immune system over time. Find healthy ways to manage stress, such as exercise, meditation, deep breathing, or engaging in hobbies that you enjoy. Taking care of your mental and emotional well-being is just as important as taking care of your physical health.
5. Exercise Regularly
Regular physical activity has numerous benefits for your immune system. It helps to improve circulation, reduce inflammation, and promote the production of antibodies and white blood cells, which are essential for fighting off infections. Aim for at least 150 minutes of moderate-intensity exercise per week.
6. Maintain a Healthy Weight
Being overweight or obese can have a negative impact on your immune system. Excess weight can lead to chronic inflammation, which impairs immune function. Focus on maintaining a healthy weight through a balanced diet and regular exercise.
7. Limit Alcohol Consumption
Excessive alcohol consumption can weaken your immune system and make you more susceptible to infections. If you choose to drink alcohol, do so in moderation. The recommended limit is up to one drink per day for women and up to two drinks per day for men.
8. Don’t Smoke
Smoking damages your immune system and increases your risk of respiratory infections, among other health issues. If you smoke, consider quitting. Seek support from healthcare professionals or join a smoking cessation program to help you quit successfully.
9. Practice Good Hygiene
Simple habits like washing your hands regularly with soap and water, avoiding close contact with sick individuals, and covering your mouth and nose when coughing or sneezing can go a long way in preventing the spread of infections and supporting your immune system.
10. Consider Supplements
While a balanced diet should provide most of the nutrients your immune system needs, certain supplements can be beneficial in certain cases. Consult with your doctor or a registered dietitian before starting any supplements to ensure they are safe and appropriate for you.
Remember, supporting your immune system is a lifelong commitment. Incorporate these strategies into your daily routine to give your immune system the best chance at keeping you healthy and protected.
