Heatstroke is an acute heatstroke disease characterized by the disorder of central nervous system and cardiovascular system caused by heat balance and water and salt metabolism in high temperature environment.
Mental nerve disorder, also known as thermal fatigue, refers to the adverse effects of high temperature environment on mood, work ability and technical efficiency.
2 Diseases induced by high temperature In a high temperature environment, because the human body is in a state of thermal stress, sympathetic nerves are excited, sweating a lot, blood viscosity increases, the cardiovascular system is in a state of high load operation, and the function of the digestive system is weakened, thus causing the aggravation of the original diseases, such as sudden changes in blood pressure in the early and late heating, which can induce heart disease, congestion and coronary heart disease. The increase of blood viscosity can cause thrombosis, which can lead to stroke; The weakness of digestive system leads to poor nutritional status of human body, which further aggravates the original organic diseases.
3 Common high-temperature diseases, colds, high temperatures in summer, vigorous metabolism and high energy consumption, while heat often makes people lack sleep, lose appetite, and the body's immunity and resistance begin to decline. In addition, it is too greedy, such as blowing fans or air conditioners directly, which leads to germs and viruses taking advantage of it, thus causing colds and colds.
In the hot summer of heatstroke, the human body sweats more, while the old people have less water in their bodies than the young people, their physiological response is slower, and they are prone to dehydration in summer. Dehydration can lead to blood viscosity, which is undoubtedly "adding fuel to the fire" for the elderly with hypertension, hyperlipidemia or cardiovascular and cerebrovascular diseases. Blood transfusion to the brain is blocked, the speed slows down, and the probability of splitting point increases.
Diarrhea diarrhea has a lot to do with improper diet. High temperature and humidity in summer will promote the reproduction and growth of bacteria, and food will rot easily. If you don't pay attention to your diet, diarrhea will occur, especially for children or infants.
Due to the influence of high temperature, about 16% people, especially middle-aged and elderly people, will have abnormal emotions and behaviors, which is called "summer affective disorder". The occurrence of this situation is closely related to temperature, sweating, sleep time and insufficient diet. When the ambient temperature exceeds 30℃, the sunshine time exceeds 12 hours, and it is moderately higher than 80%, the influence of meteorological factors on the emotional regulation center of human hypothalamus is obviously enhanced, and the occurrence of emotional disorders is obviously increased. In addition, excessive sweating and electrolyte metabolism disorder affect brain nerve activity, leading to abnormal mood and behavior.
High temperature causes death. High temperature has many effects on human health, some directly lead to diseases, some indirectly affect the original diseases, or affect people's emotions and nervous system, and the most serious consequence is death.
As a meteorological factor, high temperature itself can directly lead to severe heatstroke death, and can also be used as an inducing factor to aggravate the illness of some patients with serious organic diseases and die; In addition, high temperature will weaken people's nervous function, leading to accidents and deaths, and even people's behavioral adaptation activities at high temperature will lead to behavioral changes and dangerous behavioral factors that lead to death.
