Study: A Hot Bath Burns As Many Calories As A 30-Minute Walk

Relax! A hot bath provides almost all the benefits of exercise!




British researchers have discovered soaking in a tub of hot water has many of the same health benefits as exercise, including burning calories and reducing blood pressure, blood sugar and inflammation.

Many cultures have sworn by the health benefits of hot baths for centuries, but only recently are scientists learning why they’re so good for us.

In short, the hot water raises our body temperature the same way exercise does, triggering all the same metabolic processes without the hard work.

In their 2017 study, researchers from Loughborough University found an hour-long soak in hot water burned the same number of calories (140) as a half-hour of brisk walking.

The hot bath also reduced inflammation and lowered blood sugar, even more than exercise!

An earlier 2015 study found frequent visits to the sauna can reduce the risk of heart attack or stroke.


The idea that passive heating can improve cardiovascular function received further support when the University of Oregon published a 2016 study the following year showing that regular hot baths can lower blood pressure.

Another 2016 study found hot water immersion resulted in a greater increase in body temperature and reduction in average blood pressure than exercise,

The studies suggest “some of the cardiovascular effects of passive heating may be comparable with those of exercise,” exercise physiologist Steve Faulkner wrote for The Conversation.
