Taking a hot bath uses calories akin to exercise, says study

A new study has said that people who do not exercise but still want to stay fit can now take a hot bath which has similar benefits as work out. The study was conducted by researchers at the Loughborough University in the UK.
Say the researchers, During vigorous exercise, the body gets hot. The same thing happens while taking a hot bath.
2300 middle aged male participants were followed for an average of 20 years. According to reports, Among the men who visited the sauna once a week, half died within the time period. Among those who visited the sauna two to three times in a week, only 38 per cent died.
Speaking about this, the researchers said, The findings suggest that increased sauna usage reduced the risk of death from stroke or heart attack. This could be because of the increased blood flow and reduced blood pressure that people get when going to a sauna.
In a different study, the researchers recruited a group of participants to test the effects of a hot bath. They were fitted with monitors that recorded levels of blood sugar continuously as well as a rectal thermometer to measure the body`s internal core temperature. Say the researchers, One of metabolic fitness` important measures is the body`s ability to keep blood sugar levels within a normal range.
The study was split into two parts. In the first part of the study, participants took a hour-long bath in hot water which had a temperature of 40 degrees Celsius. They were given a light meal after the bath. The second part of the study was an one-hour cycling session to see how the hot bath`s effects fared with exercise. Results showed that taking a long, hot bath burned 140 calories, which is equivalent to a 30-minute brisk walk.
The researchers said, Cycling burned 630 calories on average. While a hot bath did not burn as many calories as exercise, the study showed that it can burn a lot of energy. What we found was that peak glucose was actually quite a bit lower after the bath, around 10 per cent lower compared to exercise. This could be partly because of the heat shock proteins release. These proteins are released by the body in response to heat, though the discharge can also be triggered by other stressors such as exercise, inflammation and infection.
