Doctors could prescribe a daily bath to help people reduce their risk of dying from heart disease and stroke, a new study suggests.
Researchers found that a bath a day can lower a person's risk of cardiovascular disease (CVD) - such as heart disease, heart attacks or strokes.
More than 30,000 people took part in a study.
Japanese participants, aged 40 to 59 with no history of cancer or cardiovascular disease, were recruited for the study and researchers then tracked them between 1990 and 2009.
They recorded just over 2,000 cardiovascular "incidents" such as stroke or heart attack.
Compared with a once or twice weekly bath or no bath at all, a daily hot bath was associated with a 28% lower risk of cardiovascular disease, and a 26% lower risk of stroke.
Frequent bathing was also linked to a lower risk of high blood pressure, according to the study, published in the journal Heart.
