WebIn order to remain alive, we all need four things. Oxygen, nutrients, and a stable range of body temperature and atmospheric pressure. Oxygen is necessary for some reactions to make ATP or energy, particularly for the brain. In fact, brain damage can occur with just five minutes of oxygen deprivation and death within 10, so breathe people.
