A Japanese study has found a significant rise of 10 times in heart stroke rate during bathing from summer to winter. As per reports, the team of researchers from the Kyoto Prefectural University of Medicine School of Nursing claims that spending too much time in a hot bath tub can increase the average heart palpitation of people.

For the study, the team seamed through medical reports of 11,000 cardiac arrest patients in the western prefecture of Osaka between 2005 and 2007. After combing through the reports, the team fund out that just before the heart stroke, about 22% were sleeping, 9% were bathing, 3% were working and a paltry 0.5% were exercising.

Further, the team went ahead by claiming 54 heart strokes per 10 million people per hour were during the bathing, while 10 heart arrests per 10 million people per hour were during exercising.

Though the team could not establish a significant association between the two, the lead researcher of the study, Chika Nishiyama, claimed, “Preventive approaches such as warming a bathroom and hallway or refraining from taking a deep, hot bath could be important for high risk people”.

The study reflects importance for the Japanese culture as they consider bathing as a regular practice in their daily life.
