Winter is the season when everything is closed and hidden in nature, and accordingly, the Yang energy of people is also hidden inside. Therefore, the basic principle of winter health care is to emphasize “seal and hide”. The cold climate will make people’s blood vessels constrict, making blood pressure higher or unstable, increasing the burden on the heart and making it easier for cardiovascular disease to occur. Most patients with kidney disease have vascular sclerosis and usually have high blood pressure, so they should pay special attention to keeping warm. Especially in the north, indoor generally have heating, and outdoor snow, the temperature difference is very big, such as not do a good job of warm measures, in the indoor is the whole body of the vasodilatation, to the outdoor vasoconstriction at once, will cause blood pressure fluctuations, such as the usual vascular sclerosis or aneurysm patients, it is easy to occur cardiovascular and cerebrovascular diseases, such as myocardial infarction, cerebral hemorrhage, etc.. The human foot is the farthest from the heart, blood circulation is poor, in the theory of Chinese medicine, the heart is fire, far away from the fire, the warming effect of fire is weaker, so in winter we should pay special attention to the feet to keep warm. In addition, some patients like to exercise in the morning, in winter should also pay attention to the early to bed and get up late, not too early to go out, or wait for the sun to come out and then exercise is good. The cold winter air makes some people prone to asthma after being stimulated by cold air. In winter, the windows and doors of most homes are tightly closed, resulting in dirty indoor air, and some families keep pets, which can easily trigger asthma due to the stimulation of pet fur and other allergens. In winter, because of the cold climate, sebaceous secretion decreases and the skin is prone to dryness and itching, plus many people with kidney disease have secondary hyperparathyroidism and skin calcification, so they are more likely to have itchy skin. At this time, in addition to the importance of maintaining quiet mentally, but also learn to regulate the bad emotions in a timely manner, when in a state of tension, excitement, anxiety, depression, etc., should be restored to mental calm as soon as possible. Itchy skin is also related to the way of bathing, some people like to use very hot water to scrub repeatedly, so that the surface of the skin is washed after the oil, the dry skin condition will become more and more serious. In winter, the number of baths should not be too frequent, and the water temperature should not be too high, after washing available some moisturizer.
