How to increase blood oxygen level?

Question

Accepted Answer

You can boost your blood oxygen level through deep breathing exercises, like pranayama, or simply by taking slow, deep breaths several times a day. Regular physical activity strengthens your lungs and heart, which improves how well oxygen moves through your body. Drinking enough water, eating iron-rich foods, and staying away from smoking also support healthy oxygen levels. If your oxygen reading stays low consistently on a pulse oximeter, see a doctor right away instead of relying only on home remedies.
