Do not dress warmly instead too much
Cold a winter, some people dress very thick, think, pass through more warm; Some people pursue graceful convenient, inside wear one the intersection of close-fitting vest and maos of shirt, the outside only a coat. In fact, it has one-sidedness that these two kinds hold. Because the cold-proof intensity of the clothes has relations with thickness of the inner air floor of the clothes. Clothes and health stick to closely, then the thickness of the air floor is almost equal to zero, cold-proof and certainly bad. After the garments of piece one one are put on, one layer of thickness of air thereupon increases, it is just thereupon increase to be cold-proof. But when one floor of total thickness exceeds 15 millimetres on the air, the inner air convection of the clothes is obviously strengthened, cold-proof to drop instead. It is obvious, should have certain piece and suitable thickness to wear the clothes in winter. The eider down outerwear has certain thickness, the air vent of the woolen fabric is not direct, can bring the suitable clothes local conditions to somebody. The leather type clothes can nearly block the air convection inside and outside the clothes, wear the leather clothing while being out in winter, the cold-proof result is the best.
The internal and external temperature difference of the room are very large in winter, if you want to wear the clothes and have good cold-proof health care results, must also pay attention to the temperature and piece of wearing the clothes in the control room. When the indoor temperature is about 15 , a shirt is worn, the surface temperature of the clothes is about 30 ; If add an undershirt and overcoat, the surface temperature of the clothes, for about 24 . Within the specific limits, the more clothes are, the less the table temperature of the clothing and temperature difference of the environment are, the less human heat distributes. So, as people enter another temperature environment (if passing in and out from a kind of temperature environment inside and outside the room) ,Will increase and decrease the clothes in right time, in order to maintain the suitable local conditions in the clothes. Indoor temperature of winter should not too high, if room internal and external temperature difference too old, human body adapt to, exchange the intersection of kindling and cold disease while being difficult.
