Firefighters are so tired that they throw up holding the car. What harm will continuous high-temperature operation do to their health?

Working at high temperature will bring a series of physiological function changes, some of which are adaptive changes, but if it goes beyond the scope, it will cause adverse effects and even pathological changes. Under the condition of high temperature, diseases directly caused by high temperature include heatstroke and mental and neurological disorders. Heatstroke is an acute heatstroke, which is mainly manifested in 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.

Occupational heatstroke: In a high-temperature working environment, due to high radiation intensity and high labor intensity, the human body is prone to occupational heatstroke due to heat accumulation in the body or imbalance of water and electrolyte. The influence of 1. on the circulatory system. When working at high temperature, the blood vessels of the skin dilate, and a lot of sweating makes the blood concentrate, which leads to increased heart activity, accelerated heartbeat, increased blood pressure and increased cardiovascular burden.

2. Effect on digestive system. High temperature will inhibit saliva secretion. The secretion of gastric juice decreases, gastric peristalsis slows down, causing loss of appetite; A lot of sweating and chloride loss reduce the acidity of gastric juice, which is easy to cause indigestion. In addition, high temperature will slow down the movement of small intestine and form other gastrointestinal diseases. 3. Influence on urinary system. At high temperature, most body fluids are excreted by sweat glands, and the amount of water and salt excreted by kidneys is greatly reduced, which makes urine concentrated and the burden on kidneys increases.

4. Influence on nervous system. Under the action of high temperature and thermal radiation, the working ability of muscles, the accuracy and coordination of movements, the reaction speed and attention of the brain are reduced. Working at high temperature is easy to consume gas and hurt yin, so it is advisable to eat food with the function of benefiting qi, nourishing yin and clearing heat. Such as: tremella, lily, pear, ebony, lotus root, etc. Other diets can be arranged according to the different effects of work on the body.
