In winter, there may be lifestyle habits that are harmful to your health. For example, during the winter season, some people often wear a mask when they go out, thinking that they can protect against colds. But that is not correct.

Experts point out that blindly wearing a mask to fight colds is not scientific, because the nasal cavity and entire respiratory tract are covered with mucous membranes. Furhtermore, there are capillaries under these mucous membranes. When cold air is drawn in through the nose, it passes through the tortuous duct and enters the lungs close to body temperature. This physiological function of the human body can be enhanced through exercise, thereby improving cold tolerance. If you wear a mask all day and the mucous membranes of the nasal cavity and the respiratory tract are not exercised, you will end up being more likely to catch a cold than you would have been if you had not excessively used a mask.

Especially during the winter, we often expose ourselfes for differencies in temperature. It is important to try to avoid this, by dressing appropriately, and protect yourself. This can prevent respiratory diseases such as colds and coughs. The cold itself is not a serious illness, but a cold can also cause insufficient blood supply to the brain cells, making you drowsy and fatigue which may affect your normal work and life, and cause complications such as for example pneumonia.
