How can you reduce the risk of hyperthermia while diving?

Setting up your equipment first is vital to reducing the risk of hyperthermia while diving because it allows for a thorough assessment of your gear and ensures that everything is functioning correctly before entering the water. Proper equipment organization and readiness minimize the time spent in warm, enclosed conditions, and help divers manage their thermal comfort.

By taking the time to prepare your gear properly, you can also ensure that you are not rushed or stressed as you enter the water, which can contribute to overheating. Additionally, having well-maintained equipment minimizes the likelihood of malfunctions that may lead to prolonged exposure in warm conditions, which is critical in preventing hyperthermia.

This approach contrasts with the other options. Increasing activity level could lead to more heat production, diving deeper could push into warmer thermal layers, and wearing a heavier suit may trap excess heat. Thus, equipment setup is a proactive measure that contributes to overall safety and comfort during the dive.
