The influence of climate on this disease is unanimously agreed that temperature, humidity and psoriasis are closely related. From the perspective of the course of individual patients with psoriasis, if there is no interference from drugs, the vast majority of them have dry and itchy skin in winter, aggravated rashes and are prone to new rashes; in summer, the skin is moistened by sweating and the rashes become less and lighter, or even all fade away. Overall, according to the relevant data, the incidence of psoriasis in the north is higher than that in the south, and the number of psoriasis patients with relapse and aggravation of the disease are more in winter and spring when the temperature is lower. Among other meteorological factors, the changes of precipitation and relative humidity are consistent with the changes of temperature. The northern region has less precipitation and a dry and cold climate, while the southern region has more precipitation and a warm and humid climate. Climate factors such as cold weather, dry air, sandy wind and short sunshine time are aspects that affect the onset and condition of psoriasis and cannot be ignored. The mechanism of the influence of climate factors on psoriasis is not very clear, but it may be that cold weather is related to the relative reduction of outdoor activities, short sunshine time, dry indoor air, lack of circulation, large temperature difference between indoor and outdoor, easy to catch cold and cold, as well as less sweating and less bathing. It is not conducive to skin cleansing and so on. Although not all psoriasis patients develop or become sicker in the cold season, cold climate is indeed an important factor affecting psoriasis. The natural pattern of psoriasis lesions is that they worsen in winter and remit in summer, or even heal themselves.
