PADI Dry Suit Diver Final Exam |Question and Answer| 100% Correct What is hypothermia? *Ans* The body core temperature dropping below normal. Why can mild hypothermia be a serious problem for scuba divers? *Ans* It interferes with clear thinking, reducing a diver's normal decision-making abilities. It also saps away strength and endurance.
