Gut bacteria may help prevent heat stroke, but human proof is limited

This narrative review looks at whether changing gut bacteria, such as using probiotics, could help prevent or treat heat stroke. The article notes that much of the available evidence comes from preclinical studies and animal experiments. Strong clinical confirmation in humans is still limited. Most supporting data for probiotics are derived from animal experiments, which means results may not directly apply to people. The review provides useful insights for the prevention and treatment of heat stroke in clinical practice, but readers should interpret protective effects in humans carefully. Safety concerns were not reported in the review, and no specific adverse events were mentioned. Because the data relies heavily on non-human research, the main reason to be careful is that human trials are needed before these methods become standard care. Readers should take from this that the idea is promising but unproven in people. More research is required to confirm if these gut bacteria changes truly work for humans facing heat stroke risks.
