What symptoms occur when suffering from heatstroke?

Heatstroke can present with a variety of symptoms depending on the severity of the condition: 1. **Early-stage heatstroke (heat exhaustion):** Symptoms include headache, thirst, dizziness, weakness in the limbs, heavy sweating, and difficulty concentrating. Body temperature may be normal or slightly elevated (usually not exceeding 37.5°C). 2. **Mild heatstroke:** Symptoms worsen, with body temperature rising above 38°C. Additional symptoms may include flushed face, chest tightness, hot dry skin, decreased blood pressure, rapid pulse, and cold, clammy limbs. 3. **Severe heatstroke:** This includes three conditions: heat cramps, heat exhaustion, and heatstroke (also called hyperpyrexia or heat stroke). - **Heat cramps:** Muscle spasms and pain may occur. - **Heat exhaustion:** In addition to the above symptoms, extreme thirst, nausea, vomiting, pale or cold, clammy skin may appear. - **Heatstroke (hyperpyrexia):** Body temperature may rise above 40°C, accompanied by absence of sweating, altered mental status, or even coma. Heatstroke has a high mortality rate and requires immediate medical attention. Heatstroke symptoms vary widely in severity, from mild discomfort to life-threatening conditions. Prompt and appropriate measures must be taken based on the patient's condition.
