The more clothes you wear, the better.
It is very cold in the cold, so many people will choose to wear more clothes, thinking that as long as they wear more, they will be healthy, but in fact it is not healthy. Because clothes themselves do not generate heat, they only play the role of isolation, so clothes only play the role of buffering the convection between cold air outside and hot air on the body surface, so that the heat of the human body can be preserved. From a physiological point of view, wearing too many clothes will inhibit the adaptability of the body's thermoregulation function and weaken the body's ability to keep out the cold. Therefore, it is enough to wear clothes with appropriate thickness in winter. If you wear too many clothes, it will be harmful to our health. We must be clear about this.
Close the doors and windows to avoid catching a cold.
It's very cold in the cold, so many people close the doors and windows all day in winter at this time, thinking that doing so can raise the indoor temperature and won't make us catch a cold. But in fact, this practice is very wrong. This is because the human body produces more than 500 kinds of chemicals in the process of metabolism, and only 149 kinds are discharged from the respiratory tract. There are a lot of bacteria, viruses, carbon dioxide and dust in the air. In this kind of air, people are prone to colds and coughs, so it is not good for health to open the window frequently to keep the air fresh. Therefore, it is necessary to open more windows for ventilation in the cold to avoid the impact of cold on the body and avoid the occurrence of colds.
It can be found that there are many situations that need our attention during the severe cold. At this time, due to the cold weather, there are many situations that we need to be careful. At this time, it is very cold. Everyone attaches great importance to health care, but many people will have some misunderstandings about health care. We must be careful to avoid the above situation.
