The skin and gut microbiomes are positively affected by thermal therapy. a Differentially abundant genera on the skin affected by psoriasis between before (T1) and after (T2) thermal treatment in patients that reported an improvement after balneotherapy. Differentially abundant genera on the unaffected skin of the same patients are available in Supplementary Fig. S2C. b Differentially abundant fecal taxa before (T1) and after (T2) balneotherapy and thermal water drinking. After balneotherapy and thermal water drinking, there is an increase in species associated with favorable metabolic health according to [39] and a decrease in species associated with bad metabolic health. Species lacking a rank of association in the original study are here reported in gray
