Heat danger for humans: How to stay safe in hot weather
The human body is a complex system that is constantly working to maintain a core temperature of around 37 degrees Celsius (98.6 degrees Fahrenheit). However, when the external temperature is too high, the body can struggle to regulate its temperature, leading to heat-related illnesses such as heat exhaustion and heat stroke.
When the body is exposed to high temperatures, it begins to sweat in order to cool down. Sweat is a liquid that evaporates from the skin, and as it evaporates, it takes heat with it. However, if the body is losing fluids and electrolytes faster than it can replace them, it can lead to dehydration and heat exhaustion.
Heat exhaustion is a mild form of heat-related illness that occurs when the body loses too much fluid and electrolytes through sweat. Symptoms of heat exhaustion include headache, dizziness, nausea, vomiting, muscle cramps, and heavy sweating.
Heat stroke is a more serious form of heat-related illness that occurs when the body's core temperature rises above 40 degrees Celsius (104 degrees Fahrenheit). Symptoms of heat stroke include headache, confusion, disorientation, seizures, coma, and hot, dry skin.
Heat stroke is a medical emergency and requires immediate medical attention. If you suspect that someone is suffering from heat stroke, call 911 immediately.
