Hyperventilation is a condition in which you start to breathe very fast.

Healthy breathing occurs with a healthy balance between breathing in oxygen and breathing out carbon dioxide. You upset this balance when you hyperventilate by exhaling more than you inhale. This causes a rapid reduction in carbon dioxide in the body.

Low carbon dioxide levels lead to narrowing of the blood vessels that supply blood to the brain. This reduction in blood supply to the brain leads to symptoms like lightheadedness and tingling in the fingers. Severe hyperventilation can lead to loss of consciousness.

For some people, hyperventilation is rare. It only occurs as an occasional, panicked response to fear, stress, or a phobia.

For others, this condition occurs as a response to emotional states, such as depression, anxiety, or anger. When hyperventilation is a frequent occurrence, it’s known as hyperventilation syndrome.

Hyperventilation is also known as:

rapid (or fast) deep breathing

overbreathing

respiratory rate (or breathing) — rapid and deep
