Hypothermia is reduced body temperature that happens when a body dissipates more heat than it absorbs and produces. [20] Clinical hypothermia occurs when the core temperature drops below 35 °C (95 °F). [21] Heat loss is a major limitation to swimming or diving in cold water. [8]
They spend most of their time underwater, so must be able to hold their breath for long periods to avoid frequent surfacing. Dive duration largely depends on the activity. A foraging sea turtle may typically spend 5–40 minutes under water [108] while a sleeping sea turtle can remain underwater for 4–7 hours.

Diving physics, or the physics of underwater diving, is the basic aspects of physics which describe the effects of the underwater environment on the underwater diver and their equipment, and the effects of blending, compressing, and storing breathing gas mixtures, and supplying them for use at ambient pressure. These effects are mostly ...
