What should be done if someone has heat exhaustion?

In cases of heat exhaustion, it is crucial to hydrate the affected person as a primary step in treatment. Providing cold water to drink helps to rehydrate the body and lowers the core temperature, which is essential when someone is experiencing signs of heat-related illness. This rehydration can aid in recovery and prevent the condition from progressing to more severe heat illness, such as heat stroke.

It's important to also consider the environment and activities of the individual suffering from heat exhaustion. They should be moved to a cooler place, ideally in the shade or an air-conditioned area, rather than being left in direct sunlight. Encouraging physical activity, like running, would exacerbate their condition, as their body is already struggling to cope with excessive heat. Applying ice directly to the skin can cause damage to the skin’s tissue and isn't the most effective or safe way to cool down someone who is overheated. Instead, gradually cooling methods and promoting hydration are most beneficial.
