What should be removed from a guest to help with overheating?

Removing heavy or restrictive clothing is important for helping a person who is overheating because such clothing can trap heat and restrict airflow, preventing the body from cooling down effectively. When a person is overheated, it's crucial to facilitate heat loss to maintain a safe body temperature. Light and loose-fitting clothing allows for better air circulation and evaporation of perspiration, which aids in the cooling process.

In situations of overheating, while other items like jewelry and accessories, cool weather clothing, or wet clothing may also play a role, heavy and restrictive clothing has the most direct impact on the body's ability to regulate its temperature by inhibiting cooling mechanisms.
