寒气逼人的严冬,对老年人的生命是一个较大的威胁。不少老年人因患“低温症”而死亡(这种死亡常常被误认为是由心肺疾病引起的)。调查表明,60岁以上的老人在气候恶劣的冬季,死亡率要比气候正常的冬季高60％。老年人的体温持续在35℃以下,医学上便称作“老人低温症”。老年人容易罹患此病,是因为老人的身体机能都已老化,体内产热减少,能够觉察到温度降低的身体机理已经丧失了敏感,在与寒冷的接触中,皮肤血管反应迟钝,不能很好地收缩,丢失的热量也比较大,因而不能使体温维持在一定水平。老年冬季低温症的形成一般需要数天时间。当老人体温降到35OC-36℃时,一般自己还能诉说寒冷,但有嗜睡、无精打采的症状;若体温低于35℃,就可能
The severe cold winter is a big threat to the life of the elderly. Many elderly people die of “hypothermia” (deaths are often mistaken for heart and lung disease). According to the survey, the elderly over the age of 60 in the harsh winter climate, the mortality rate is 60% higher than the normal winter climate. The elderly’s body temperature continued below 35 ℃, medically referred to as “hypothermia in the elderly.” The elderly are prone to the disease because their body functions are aging and the body produces less heat. Body mechanisms that can sense a decrease in temperature have lost their sensitivity. In cold contact, the skin vessels become unresponsive and can not do well To shrink, the loss of heat is relatively large, and therefore can not maintain body temperature at a certain level. Geriatric winter hypothermia usually takes several days to form. When the elderly body temperature dropped to 35OC-36 ℃, the general can tell themselves cold, but drowsiness, listlessness symptoms; if the body temperature is below 35 ℃, it may
