What do rapid repetitive exhales do to your body

Rapid repetitive exhales, commonly associated with cyclic hyperventilation or techniques like Wim Hof and Tummo breathing, can have significant physiological effects. When you engage in rapid deliberate breathing, such as a series of 25 deep inhales and exhales, you essentially alter your body's chemistry by increasing oxygen intake and exhaling carbon dioxide. This process stimulates the release of adrenaline from the adrenals, which enhances alertness and can make you feel more energetic and warm 1 2.

However, it's important to approach such breathing techniques with caution, especially if you're prone to anxiety or panic attacks, as the increased adrenaline can also heighten feelings of anxiety 3. Additionally, combining these breathing exercises with activities such as breath holds near water can be dangerous, leading to risks like shallow water blackout 1. Always ensure that such techniques are performed in a safe environment and consult a healthcare professional if necessary.
