How to prevent a cold? Here are the 4 tips given by doctors

Colds and other viral illnesses may have been less common in the past two years due to mask wearing, social distancing and other pandemic restrictions, but that doesn't mean you shouldn't take care of your health. Do these things to strengthen your immune system:

Too little water intake weakens the natural mucous barrier in the throat, pharynx and nose. At the same time, it weakens lung tissue, which makes life easier for pathogens. For every kilogram of body weight, you should drink 30 milliliters of liquid during the day, preferably water or tea without sugar. If, for example, you weigh 70 kilograms, this means that you need 2.1 liters of fluids per day.

Eat foods rich in iron, zinc and selenium

Sesame seeds, pumpkin seeds, oats and lentils have something in common – they are rich in iron and zinc. These micronutrients can ensure that our T cells, which detect viruses in the body, work well. Selenium also helps our physical defenses and can be found in egg yolks, peanuts, whole grains.

Stress damages the body and thus the immune system. It reduces the number of immune cells in the blood and T cells. This is an additional reason to allow our bodies regular breaks. Even a few minutes of rest lowers the stress level.

Even if it's cold, exercising in the fresh air is useful not only to strengthen your immune system but also to improve your mood. However, you should not overdo it. Choose what works best for you, whether it's a run or a light walk.
