Keeping warm and cold is the most important situation in winter. At this time, many people will be afraid of cold. So if you want to be healthy in winter, then keeping warm and cold becomes the basis of health, but warm in winter. Many people will make some mistakes when choosing the wrong method. Let's take a look at the specific problems.


Sleeping


Because it is relatively cold in winter, many of us are used to sleeping with our heads covered in the quilt at this time. This approach can help us to raise the temperature and also feel warmer temporarily, but the oxygen in the quilt will increase Less and less, carbon dioxide and unclean gas accumulate more and more, so after a heavy sleep, we often feel drowsy, fatigued and weak, and this heating method is unhealthy.


Often wear a mask


And on cold days, many people are accustomed to wearing masks at this time, which can avoid direct contact with cold air. However, in fact, due to the rich blood vessels and spongy tissue in the nasal mucosa, blood circulation is very strong, which has a warming effect on the cold air inhaled. The nasal ducts are very tortuous and can heat cold air. When passing through the nose, it will be detrimental to the health of the nose, so it is said that no mask can be better to keep warm.


Wash your face with hot water


Washing your face with hot water is very good in winter, but because the face of the person is stimulated by cold air in winter, the sweat glands and capillaries are in a contracted state. At this time, if we wash our face with hot water, it will expand rapidly when encountering hot water, but after the heat is released, it will return to its low temperature state. Capillary blood vessels are shrunk in such a way that they can easily cause wrinkles on the face.


It is worthy of our attention to keep warm in winter. This is the basis of health in winter, but if you ca n’t pay attention to warmth at this time, your body is vulnerable. At the same time, there will be some misunderstandings in keeping warm in winter. We need to be careful to avoid it so that we can better promote health.
