Butt breathing, more formally called intestinal or rectal respiration, refers to the absorption of oxygen through the lining of the lower digestive tract. While it may sound humorous or fringe, the concept has a real scientific basis—primarily in animal biology and experimental medicine.
Certain species, such as loaches, sea cucumbers, and some turtles, naturally use intestinal respiration to survive in low-oxygen environments. In humans, however, butt breathing is not a natural or efficient method of respiration. Interest in the topic grew after researchers demonstrated that oxygen delivered to the intestines of mice and pigs could temporarily support survival under extreme oxygen deprivation. These studies were designed for emergency medical research, not everyday health practices.
Despite online claims, there are no proven health benefits of butt breathing for humans, such as increased energy, detoxification, or improved circulation. The human colon is not adapted to meaningfully exchange oxygen, and attempting oxygen enemas or similar practices outside of medical research can be dangerous, increasing the risk of infection, tissue damage, or air embolism.
From a health perspective, butt breathing is best understood as a scientific curiosity and potential emergency medical concept, not a wellness technique. Healthy breathing, cardiovascular fitness, and oxygen delivery are far more safely supported through exercise, proper posture, and lung-based respiration—not experimental shortcuts.
As an energetic cultivation butt breathing is breathing like a tree. Some energy practices do this type of breathing in their meditation and energy cultivation because they believe that doing butt breathing they can mimic a tree and achieve longevity. Even immortality. Those who succeed in butt breathing can actually do not need to eat as they can get nourished by sunlight and cosmic energy.
