Wash your hands
Wash your hands thoroughly several times a day. According to studies, this is one of the most effective ways to ward off a cold. Shaking hands and giving kisses should be avoided at this time.

Get enough sleep
Get plenty of sleep. Here, too, tests have shown the benefits in the body's fight against cold germs. People who get a good night's sleep have better immune systems and are less likely to fall ill.

Keep warm
Keep warm. Actually a truism. But many people don't take it to heart, especially on warmer days. That's when you see a lot of airy clothing on the street. This is dangerous because it quickly leads to gradual hypothermia. However, ventilate the house well so that the dry, stale heating air disappears.

Don't go on a diet
Don't go on a strict diet. The body now also needs a little power food to strengthen its immune system. Fresh vegetables, lots of fruit, plus some meat, sausage or cheese: this is good for the immune system.
