What occupational diseases are caused by high temperatures?

Generally, occupational diseases caused by high temperatures include heatstroke, heat fatigue, heat cramps, heat exhaustion, and heat stroke. A detailed analysis is as follows:

1. Heatstroke: When the working environment is excessively hot, the human body may fail to dissipate heat effectively, leading to elevated body temperature and symptoms of heatstroke. These symptoms include dizziness, weakness, nausea, vomiting, dehydration, and loss of consciousness.

2. Heat fatigue: Prolonged work in high-temperature environments may reduce the body's ability to adapt to heat, resulting in heat fatigue. Symptoms include fatigue, reduced physical performance, difficulty concentrating, irritability, and decreased work efficiency.

3. Skin problems: Long-term exposure to high temperatures can affect the skin due to heat, humidity, and sweat, potentially causing skin issues such as heat rash, thermal injury, burns, and skin infections.

4. Heat cramps: Heat cramps are muscle spasms caused by prolonged work in hot environments, typically resulting from excessive sweating that leads to fluid and electrolyte imbalances. Symptoms include weakness, dizziness, and fatigue. Prevention involves timely rest, maintaining adequate fluid intake, and avoiding overexertion.

5. Heat stroke: Heat stroke is a severe illness caused by failure of the body’s temperature regulation system in high-temperature conditions. Symptoms include high body temperature, loss of consciousness, seizures, rapid heartbeat, and breathing difficulties. This is a medical emergency requiring immediate treatment.

If any of the above symptoms occur, prompt medical attention at a hospital is necessary.
