In winter, especially in the north, for families with elderly people, experts point out that the room temperature should be kept between 22-25 degrees, not too high or too low. If the temperature is too high, it is easy to catch a cold. But if the temperature is too low, it will lead to more serious consequences. First of all, it will cause blood to flow from the skin to the internal organs. In order to keep warm, it must be forced to contract, which will increase the burden on the human heart. For the elderly with cardiovascular diseases, it is easy to cause myocardial infarction and sudden death. Secondly, the elderly are prone to joint pain, and the low indoor temperature may aggravate the pain. Joints need to be in a warm environment to have enough lubricant. Reducing the friction between joints is beneficial to relieve joint pain, especially for the elderly who have suffered trauma. Keep warm. Third, the elderly are inconvenient to move. If the room temperature is low, they will wear more clothes, which will bring more obstacles to their sports. For example, it will affect them to go to the bathroom to pee when they sleep. Low temperature will also increase the frequency of urinating in the bathroom, forming unnecessary safety hazards. According to reports, more than 80% of bone injuries in the elderly are caused by falls due to mobility difficulties. In order to reduce the occurrence of such accidents, we should find out the reasons from many aspects, among which the simplest method is to keep the room warm, reduce the thickness of clothes and increase the convenience of moving.

Indoor temperature should be based on the thermometer at home, and the temperature sensitivity of the elderly will decrease. It is not comprehensive to judge whether it is cold or not by physical feeling alone. Objective room temperature is a direct factor affecting the health of the elderly. In areas with heating conditions, heating must be guaranteed. In areas without heating conditions, air conditioning and other heating equipment should be used reasonably to adjust the indoor temperature to avoid dangerous heating methods such as burning coal. The safety awareness of the elderly is relatively weak, and coal heating is prone to gas poisoning, so air conditioning is the safest and most convenient form of collective heating for the elderly. Compared with the electricity bill of several hundred yuan a month, the comfort and health of the elderly are more important.
