    The doctor of traditional Chinese medicine thinks, "the head is the will of the ZhuYang", the human body the hands and feet have three Yang meridians are gathered here, the winter sun be the spirit human body is the most easy to become separated from the head, feel sense of cold. Medical tests showed that the stationary state don't wear a hat in the environmental temperature of 4 ℃, the loss of heat from the head of the human body 60% of the total quantity of heat. In particular the frail elderly, sun be the spirit and the head easily by cold evil invasion. Thus, head warm heat balance is of great significance to maintain the human body.
 
    Back for bladder meridians following the main parts, which by the "fence" like a guard outside, have to resist invasion of the role of the invaded, winter cold evil invade the body, often bear the brunt. Back and du meridian courses, the meridian is "the sea of Yang pulse", to the governor a suit of Yang meridians, cold, easy to broken Yang in. The circulation of the blood back to limbs, and less abdominal fat distribution, therefore, also nots allow to ignore to the back to keep warm.
 
    The foot is the start of human foot three Yin meridians, relative to the head belong to Yin, sun be the spirit of partial failure. Feet furthest away from the heart, blood supply and weeks, skin principals adipose layer is thinner, warmth retention property is poorer, therefore, skin temperature, the lowest. As folk said, cold starting from the foot. Modern medical research found that foot and nerve has a close connection between the upper respiratory tract mucous membrane, once the cold, will cause the respiratory tract mucosa capillary contraction, reflective ciliary motion is abate, resistance to drop, cause upper respiratory tract infection. The foot of the warm winter season.
 
    By the known, in the chill winter, wearing the right hat, a form-fitting cotton (maoist) vest, wear warm shoes, can yet be regarded as the best choice to warm.
