Jumping into cold water can be deadly

It is very dangerous to jump into a cold lake. When jumping into cold water, two reflexes set in. 1. When you are completely submerged in water, your heart rate slows down. This phenomenon is called the diving reflex. 2. At the same time, cold water makes your pulse faster. The pulse becomes particularly rapid if the body was previously heated up. The heart is confused and does not know what to do. That's why it stops beating. It's like in a car if you step on the brakes and the gas at the same time. Cold Shock can aspire within two minutes. The water doesn't have to be ice cold. 12 to 14 degrees are enough for this. A cold shock can affect everyone, including healthy and athletic people. So don't just jump in at the deep end, but always slowly get used to the temperature
