Take baths whenever you can — don’t limit yourself to showers
In a Japanese study, people who soaked in a bathtub almost every day had approximately 28% lower risk of cardiovascular events and approximately 46% lower risk of cerebral hemorrhage compared to those who bathed less than twice a week.

It costs a bit more in water and electricity; each bath takes about half an hour.
A Japanese study of 30,000 people, aged 40 to 59, followed for 19 years, involving a total of 2,097 cardiovascular events. People who bathed almost every day had approximately 28% lower risk of cardiovascular events compared to those who bathed no more than twice a week (hazard ratio 0.72, 95% CI 0.62–0.84, which is the confidence interval). Coronary heart disease was lower by approximately 35% (0.65, 0.45–0.94). Stroke was lower by approximately 26% (0.74, 0.62–0.87). Cerebral hemorrhage was lower by approximately 46% (0.54, 0.40–0.73).

Open source linkThe controversy lies in: these results were obtained within the Japanese population and bathtub culture; most families in China do not have the conditions to bathe every day. Additionally, the water should not be too hot, and you should not soak for too long. For the elderly and those with cardiovascular or cerebrovascular diseases, excessively high water temperature and soaking for too long are instead dangerous. In Japan, 7,776 people drowned in bathtubs in 2024. The Japan Consumer Affairs Agency stated that common causes are the large temperature difference between the room and the bathroom in winter and soaking in hot water for too long. Do not bathe, soak in hot springs, or use saunas after consuming alcohol; see Section 22, Item 11 (Do not soak in hot springs after drinking alcohol).
