Por que os exercícios de respiração podem causar tontura
Light-headedness during a breathing exercise is usually harmless and comes from breathing more than your body needs, which lowers carbon dioxide in the blood. The fix is simple: slow down, make the breaths smaller, and let the exhale be relaxed. If dizziness is strong or persistent, stop and breathe normally.
It is a common, usually benign experience - and a clear signal to make the breath gentler.
Common, benign explanations
Most dizziness comes from over-breathing - taking in more air than the body needs. This lowers carbon dioxide levels, which can cause tingling, light-headedness, or a floaty feeling. It usually passes quickly once you return to normal breathing. [1]
When to stop
Higher-risk situations
- Never practice breath holds or intense breathing while driving, in or near water, or standing where a fall would be dangerous.
- Take extra care if you have a history of fainting, low blood pressure, or a heart or respiratory condition.
When professional advice is appropriate
If dizziness is frequent, severe, or comes with chest pain, palpitations, or fainting, speak with a healthcare professional rather than treating it as something to breathe through.
Safer alternatives
Slow down and breathe less: a small, quiet breath through the nose with a relaxed, slightly longer exhale is a good default. Avoid big, deep, forceful breaths.
