Effect of high temperature on human health
First, the impact on physiological function:
Regulation of body temperature: Meteorological conditions, labor intensity, working hours and human health during high temperature operation will have an impact on the regulation of body temperature.
Water and salt metabolism: when working at high temperature, perspiration increases obviously, which can lead to the loss of water, sodium oxide, potassium, calcium, magnesium and vitamins. If it is not replenished in time, it will lead to severe dehydration, circulatory failure, thermal spasm and so on.
Diet and nutrition
Circulatory system: when working at high temperature, the cardiovascular system is often in a state of tension, which can lead to changes in blood pressure. Hypertension patients increase with the increase of working years in high temperature.
Digestive system: it can cause loss of appetite and indigestion, and the prevalence of gastrointestinal diseases increases with the increase of working years.
Neuroendocrine system: The central nervous system may be inhibited, and the attention and working ability may decrease, which is prone to industrial accidents.
Urinary system: because a large amount of water is excreted by sweat glands, renal insufficiency and proteinuria may occur if it is not replenished in time.
Second, heatstroke disease: According to the different pathogenesis and clinical manifestations, it can be divided into three types.
Heatstroke: Because the heat generated in the body exceeds the heat dissipation, it causes the heat accumulation in the body, which leads to the disorder of body temperature regulation. It is the most serious type of heatstroke, with critical illness and high mortality.
Typical symptoms are: sudden high fever, anal temperature often above 465438 0℃, dry skin, heat without sweat, different degrees of consciousness disorder, and severe cases may have abnormal liver and kidney function.

Thermal spasm: It is caused by imbalance of water and electrolyte.
The clinical manifestations are: obvious muscle spasm causes contraction pain, and the spasm is symmetrical. The mild one does not affect the work, and the severe one is serious. The patient is conscious and his body temperature is normal.
Heart failure: It is caused by heat that dilates peripheral blood vessels and dehydrates a lot, resulting in decreased circulating blood volume and insufficient intracranial blood supply.
The main clinical manifestations are: dizziness, headache, palpitation, nausea, vomiting, sweating, then syncope, short-term drop in blood pressure, generally does not cause circulatory failure, hypothermia.
