Scientists from Kyushu University in Japan found that bathing in hot springs has a positive effect on the composition of the gut microbiome. Research results published In Scientific Reports.
The study examined how bathing in different categories of spas affected the gut microbiome of healthy people. A total of 127 people living in Japan participated in the experiment. Participants were asked to choose a hot spring location and spend at least 20 minutes in the water every day for a week. Volunteers were advised to maintain normal sleeping and eating patterns and avoid alcohol use and overeating.
Fecal samples were collected from all participants to evaluate the state of the intestinal microbiota before and after the experiment. Test results showed that the number of bacteria of various types increased significantly in the participants’ intestines. Oscillibacter and Parabacteroides were the species that increased in abundance in the gut microbiome of visitors to plain water hot springs. Ruminococcus, Oscillibacter and Bifidobacterium bifidum increased in those exposed to bicarbonate water, while Alistipes increased in those exposed to hydrogen sulfide sources. There were no significant changes in chloride sources before and after swimming.
An increase in the number of some of these bacteria is associated with health benefits. These include improving glucose tolerance, reducing the risk of constipation, strengthening intestinal immunity and protecting against enteropathogenic (caused by various pathogenic microorganisms) infections.
It is stated that some bacteria may have a two-way effect on health. Increased numbers of Parabacteroides may both aggravate amyotrophic lateral sclerosis symptoms and confer longevity.
