Hyperventilation is breathing too deeply and faster than normal. This causes too much carbon dioxide to be exhaled. As a result, levels of carbon dioxide in the blood and brain tissue drop.


Signs & Symptoms

•  Your heart pounds.

•  It feels like you can’t get enough air.

•  You feel tingling and numbness in the arms, legs, and around the mouth.

•  You feel a sense of doom.

•  You may pass out.

Symptoms usually last 20 to 30 minutes, but seem to last hours. Though scary, hyperventilation is not usually dangerous.

•  Anxiety is the most common cause.

•  Panic attacks.

•  Central nervous system problems.


Self-care may be enough to treat hyperventilation. If it persists or occurs with other symptoms, seek medical care.
