Chika Nishiyama, researchers from Kyoto Prefectural University revealed that after observing some 11,000 cases of cardiac arrest in Osaka. The observation was done in 2005-2007, so the past few seasons.
At the heart attacks that occur after a warm bath, the rate of incidence 10 times higher during the winter compared to a warm seasons. It means a heart attack after a hot shower more often the case when the cold weather, when many people want to stay warm.
In addition to a warm bath, the other activities most people do before the heart attack is sleeping. Sports actually ranks third with only 0.5 percent, less than a shower or bath with warm water.

Activity Percentage (%)
Sleep 22
Warm water bath 9
Work 3
Sports 0.5
Other 65.5
In addition to more incidence rates, are also more vulnerable to heart attacks occur after a warm bath than after exercise when viewed from the duration. With the same duration, 54 of the 10 million people suffered heart attacks after a warm bath, while only 10 out of 10 million people experience after exercising.
Although not yet determined the relationship and the mechanism, Nishiyama figured a hot shower in cold weather causes the blood pressure dropped dramatically. As a result a sudden decrease of cardiac function and has a disorder or a heart attack.
"It is better to do pendegahan to avoid soaking in warm water during cold weather, especially for those who do have a problem with the heart," he wrote in a report published in the journal Resuscitation.
