Explanation:

Survival float (also known as dead man's float) is a manoeuvre that allows a person to survive in the water for a very long time while floating. This way of floating allows the person to save energy while remaining conscious. First of all, the person should take a deep breath of air. This breath should completely fill up the lungs. The air will allow the person to float more easily. Afterwards, the person should relax and let his body float until the next breath has to be taken again, starting the cycle once more.
