What is Tummo breathing?

Tummo breathing, also known as Wim Hof breathing, involves rapid, deliberate hyperventilation—often through cyclic breathing patterns—and has been linked historically to traditional Tibetan practices. This technique generally consists of inhaling and exhaling deeply for several cycles, which can lead to a significant release of adrenaline from the adrenal glands. The release of adrenaline is known to activate the body’s immune response, potentially countering infections and boosting immune function through the release of killer cells from the spleen and other immune organs.

The practice is believed to produce heat in the body, raising body temperature—akin to the effects of exposure to cold, such as ice baths, which elicit similar physiological responses. However, Tummo breathing is not without its risks: it is strongly advised against performing these exercises near water or if you are prone to anxiety or similar conditions, as they could induce adverse effects like anxiety attacks.

The benefits of Tummo breathing include its potential to manage stress, enhance alertness, and modulate the immune system effectively. This breathing style forms part of a broader category of practices that harness the body's response to stress and cold to improve physiological resilience and health outcomes. In exploring these practices, it's crucial to understand the underlying mechanisms, such as how increasing and decreasing adrenaline and carbon dioxide levels in the body can impact health and immunity 1 2 3.
