Do you often have symptoms characteristic of a cold and are you curious about the cause?
The cause may be vitamin deficiency, dehydration, diet, immune system disorders.
You may be surprised, but sometimes there is a direct connection between insomnia and weakened immunity, which in itself is a cause of frequent illness. During sleep deprivation, the body's natural process of fighting infections and viruses is significantly reduced.
You should pay attention to personal hygiene, in particular, washing your hands regularly with soap and water.
Hands constantly touch dirty objects and surfaces throughout the day, so you are constantly exposed to external bacteria and viruses.
To prevent harmful microbes from entering the body, you should wash your hands often and avoid touching your face. You should spend at least 20 seconds washing your hands - (sing the famous song "Happy Birthday").
You should also pay attention to your teeth, because the oral cavity is a kind of window to health. When the number of harmful bacteria in the oral cavity is high, an inflammatory process develops, and therefore any area of the body is affected.
One of the effective methods of preventing frequent colds is stress management. Chronic stress, in fact, destroys the body, reduces immunity, the body can no longer produce a natural immune response.
