why are most people able to hold their breath longer after hyperventilating?
When a person hyperventilates, they are taking in more oxygen than the body actually needs. This causes a decrease in the levels of carbon dioxide in the blood, which results in a temporary alkalosis (increased pH level) in the body. This alkalosis triggers the body's natural response to breathe less frequently in order to retain more carbon dioxide.
As a result, after hyperventilating, the body has higher levels of oxygen and lower levels of carbon dioxide, which allows a person to hold their breath longer before the urge to breathe becomes too strong. However, it is important to note that hyperventilating can be dangerous and should not be done excessively or for prolonged periods of time.
