Prior to this study, scientists were able to show that hot baths can improve insulin sensitivity of patients with Type 2 diabetes. However, they were unable to determine the mechanism through which this occurs. This time, a different team of researchers from Loughborough University and Nottingham Trent University in the U.K. looked deeper into the effect of a hot bath on glucose metabolism. Their theory was that this influence revolves around the body's inflammatory response since chronic, low-level inflammation has been associated with an increase in insulin resistance.

Doctors often recommend exercise for patients who suffer from chronic inflammation and insulin resistance. Exercise is effective in improving these conditions since it can induce a brief inflammatory response, which is then succeeded by an extended anti-inflammatory response. Unfortunately, not everyone has the capacity to perform workouts. Because of this, the researchers wanted to see if a hot bath, which is a different type of physical stressor, could have the same effect as exercise.
To do this, the researchers first gathered male participants who were overweight and lived a mostly sedentary lifestyle. Then, they collected blood samples before doing a hot bath intervention, with a water bath set at 39 C. The researchers then took another set of blood samples right after the bath, and again two hours later. Overall, there were a total of 10 hot water immersions in the course of two weeks, with each session lasting for an hour.
The results showed that a single water bath session caused a spike in interleukin, a commonly used marker for inflammation. In addition to this, there was an increase in nitric oxide (NO), which is important for the relaxation of blood vessels and the lowering of blood pressure. Scientists also believe that NO has anti-inflammatory properties and that it can improve glucose uptake by the cells.
After all the immersions were completed, the participants exhibited reduced levels of fasting blood sugar and inflammation. This result was similar to the effect of exercise wherein there is an initial increase in inflammation before a long-term decrease is observed.
From these results, the researchers concluded that hot water immersion can improve inflammation and glucose metabolism. They also noted that these observations have significant implications for improving metabolic health of people who cannot exercise.
