Researchers suggest that a properly conducted bath routine could potentially lower blood pressure, but caution that not everyone will experience the same benefits.
A recent scientific review, published in the Journal of Applied Physiology, reveals that a normal bath can be transformed into a form of passive heat therapy which may help in lowering blood pressure. The study emphasizes the importance of maintaining water temperatures between 39°C and 40°C during longer bathing sessions to achieve significant benefits. Historically, hot water immersion has been utilized in various cultural contexts, such as Roman baths and Japanese onsen, suggesting a longstanding acknowledgment of its therapeutic properties.
The researchers noted that while hot water immersion can contribute to lower blood pressure, results may vary among individuals. Factors such as a person’s overall health, underlying conditions, and the specific method of immersion can influence effectiveness. Consequently, the review calls for cautious implementation, highlighting that not everyone may experience the expected health benefits from such baths.
Despite the potential benefits, the findings also indicate that a typical bathing experience, with temperatures usually ranging from 33°C to 37°C, might not be sufficient for achieving the desired outcomes. This raises important questions about how individuals can safely and effectively incorporate passive heat therapy into their health routines, as well as the need for further research in this field to better understand who may benefit the most from this method.
