According to health experts, as the temperature drops, falls, frostbite, colds and traffic accidents have become the main factors affecting health. The temperature changes greatly and is easy to induce. In snowy days, most of the falls of the elderly are wrist and femur fractures, while those of young people are cartilage contusions.
From the perspective of prevention, the elderly should reduce outdoor activities, and it is best to travel with the help of others. Pedestrians should try to slow down the speed of cycling or walking when traveling to avoid slipping.
Some people always wear more clothes in winter because they are afraid of the cold. In fact, this is very unhealthy. Health experts explained that because people's brains and muscles are at rest during sleep, the number of heart beats is reduced, muscle reflex and tension are weakened, and the activity of the central nervous system is slowed down. At this time, taking off clothes and sleeping can quickly let all organs of the body get a good rest.
Because human skin will secrete and emit some chemicals, sleeping with clothes will undoubtedly hinder the normal "breathing" of the skin and the evaporation of sweat. The compression and friction of clothes on muscles will also affect blood circulation, leading to the decrease of body surface heat. Even with a thick quilt, you will feel cold. Therefore, it is not advisable to wear thick clothes to sleep in cold winter.
When there is little precipitation during the cooling period, it is windy, windy and dry, and the indoor humidity is also low. In particular, the use of heaters will make the indoor air drier, which will easily lead to rough and wrinkled skin and even chapped skin.
Moreover, too low air humidity can easily lead to dehydration of respiratory mucosa, decreased mucus secretion, weakened cilia, and weakened scavenging ability of respiratory tract, which can not discharge dust and bacteria from respiratory tract in time, which is easy to induce and aggravate.
In this regard, health experts suggest that families using heaters should pay attention to indoor humidity, and it is best to have a hygrometer. Generally speaking, living in an environment with relative humidity of 40% ~ 60% is the most comfortable. If the relative humidity is low, it should be adjusted accordingly.
For example, sprinkle some water on the floor, or mop the floor with a wet mop, or put a basin of water near the heater to increase humidity. If you keep daffodils indoors, you can not only adjust the relative humidity indoors, but also make the room look alive.
