Adults primarily prevent overheating through evaporative cooling. This process involves the body losing heat as sweat evaporates from the skin's surface. When sweat evaporates, it absorbs heat from the body, which helps to lower the body's temperature.

This method of cooling is particularly important because it effectively regulates body temperature during physical exertion or in hot environments. The body naturally produces sweat, and the rate of evaporation is influenced by factors such as humidity, airflow, and temperature; in environments with low humidity, evaporative cooling is much more efficient.

While other cooling methods like radiative, conductive, and convective cooling also play roles in temperature regulation, none are as significant in adults' ability to prevent overheating as evaporative cooling. Radiative cooling involves heat loss through radiation, which is less effective in hot conditions where the environment is warmer than the body. Conductive cooling relies on direct contact with cooler surfaces, which cannot always be relied upon in various environments. Convective cooling depends on airflow to remove heat, but if the air temperature is high or stagnant, this method is less effective.
