It's cold in winter, not the thicker you go through. Conversely, it will cause physical discomfort, so how should we wear it? What other misunderstandings should we pay attention to in winter health preservation?
In cold winter, many people think that the warmer you go through more. In fact, this is a one-sided view. Because the clothes themselves do not produce heat, only play the role of isolation, can buffer the convection between the cold air outside and the hot air on the body surface, so that the heat of the human body can be preserved, thus feeling warm. Of course, the warmth will be strengthened after wearing clothes one by one. However, if the thickness of air layer formed between clothes exceeds 1.5 cm, the convection of air in clothes increases obviously, and the warmth retention decreases.

Indoor temperature regulation should be appropriate, when going out, should gradually adjust the temperature to 15 C is appropriate. Sleep temperature in the evening should be between 15 and 18 degrees Celsius.
