Did you know your Body and Brain need Oxygen to Survive? This firefighter shows you how much Oxygen is cut off when you deprive yourself of Oxygen.The brain uses about 20% of the body’s oxygen supply, which allows it to perform conscious and autonomic processes. “Brain cells are very sensitive to a lack of oxygen. Some brain cells start dying less than 5 minutes after their oxygen supply disappears. As a result, brain hypoxia can rapidly cause severe brain damage or death.”
