Analysis of the effect of hot spring bathing on serum melatonin levels and its association with sleep and anxiety

ObjectiveTo explore the improvement effect of typical hot spring bathing on sleep and anxiety and its correlation with serum melatonin level in Guizhou province.

MethodsFive typical characteristic hot springs in Guizhou were selected according to the geological type of hot spring water. A total of 226 residents in these areas were selected for the survey and the self-rating scale of sleep(SRSS)and the self-rating anxiety scale(SAS)were used to measure their scores before and after hot spring bathing, and the correlation between the changes of SRSS and SAS scores and the serum melatonin levels were analyzed.

ResultsThe SRSS and SAS scores of the respondents after hot spring bathing were lower than before, and the difference was statistically significant(P < 0.05). Serum melatonin levels after hot spring bathing were significantly higher than before(P < 0.05), and there was a negative correlation between the changes of SRSS and SAS scores and serum melatonin levels(P < 0.05).

ConclusionTypical hot springs in Guizhou Province can significantly improve the sleep quality and anxiety state, which are related to the elevation of serum melatonin level.
