Just last year, a study concluded that taking a hot bath before bed does help with sleep,media reported. Now, a new study suggests that regular hot baths may also be good for the body, and it may be found to reduce the risk of dying from cardiovascular disease. The study, conducted jointly by a Japanese research institute, tracked and evaluated 30,076 middle-aged Japanese participants from 1990 until December 2009.
At the beginning of the study, each participant was asked to fill out a questionnaire that described their personal bathing habits and information such as exercise habits, diet, alcohol intake, weight, average sleep time, medical history, and current medications.
Throughout the 19-year monitoring period, there were 2,097 cardiovascular diseases in the study group, including 275 heart attacks, 53 sudden cardiac death, and 1,769 strokes. After considering potential factors, the researchers determined that taking a hot bath once a day (rather than once or twice a week) reduced the overall risk of cardiovascular disease by 28 percent and stroke risk by 26 percent.
A more detailed analysis shows that the higher the water temperature, the lower the risk of cardiovascular disease. However, it has also been pointed out that bathing in overheated water increases the risk of drowning deaths caused by overheating, especially among the elderly.
In addition, the new study also found that regular hot baths are associated with reducing the risk of high blood pressure.
The study has been published in Heart.
