Hot Baths Lower Blood Pressure, Boost Health

Hot water immersion, a form of passive heat therapy, is gaining attention for its potential health benefits. Researchers analyzing scientific evidence suggest that maintaining water temperatures between 39°C and 40°C for 30 minutes or longer can significantly lower blood pressure by dilating blood vessels. This practice, historically used in various cultures, may also contribute to reduced risk of cardiovascular disease.

While the therapy shows promise, its effectiveness varies. Older individuals with existing, treated high blood pressure tend to experience more consistent positive outcomes. In contrast, younger, healthy individuals and those with untreated hypertension show minimal or no sustained results. Beyond blood pressure management, hot water immersion has also been linked to improved sleep quality, reduced stress markers, and enhanced psychological well-being.
