1. Sleep More Worry Less

Inadequate sleep may increase your risk of getting sick. Most adults should get at least 7 hours of sleep per night.

2. Eat Vegetables and Whole Plant Foods

Several whole plant foods contain antioxidants, fiber, and vitamin C, all of which may lower your susceptibility to illness.

3. Healthy Fat is Key To Successful Immune System

Healthy fats like olive oil and omega-3s are highly anti-inflammatory. Since chronic inflammation can suppress your immune system, these fats may naturally combat illnesses.

4. Fermented Food and Probiotics 

Gut health and immunity are deeply interconnected. Fermented foods and probiotics may bolster your immune system by helping it identify and target harmful pathogens. The most common fermented foods that naturally contain probiotics, or have probiotics added to them, include yogurt, kefir, kombucha, sauerkraut, pickles, miso, tempeh, kimchi, sourdough bread, and some cheeses.

5. Avoid Sugar

Added sugars contribute significantly to obesity, type 2 diabetes, and heart disease, all of which can suppress your immune system. Lowering your sugar intake may decrease inflammation and your risk of these conditions.

6. Exercise and Cardio

Moderate exercise can reduce inflammation and promote the healthy turnover of immune cells. Jogging, biking, walking, swimming, and hiking are great options.

7. Drink Water Stay hydrated

Given that dehydration can make you more susceptible to illness, be sure you’re drinking plenty of water each day.

8. Worry Less, Live More

Lowering your stress levels through meditation, yoga, exercise, and other practices can help keep your immune system functioning properly.

9. Use Supplements

Though some supplements may fight viral infections, none have been proven to be effective against COVID-19. If you decide to supplement, make sure to purchase products that have been tested by a third party.
