What causes a polar bear swimmer to get a strong urge to breathe while in the water?
When entering cold water the skin is immediately cooled and this is sensed by cold receptors very close to the skin surface. This results in an initial gasp, followed by rapid uncontrollable breathing, as well as an increase in heart rate and blood pressure and is also known as the ‘cold shock response’.
Why are polar bears so powerful?
On top of that, they have a water repellent thick fur body protection which allows them to shake off the ice that forms after going into freezingly cold water. Polar bear genetics, in addition to their hypercarnivore diet and predatory instincts, makes them absurdly strong animals.
