Here is the link to an old, but interesting study I found. It is about upper dorsal thoracoscopic sympathectomy and its effects on total amount of body perspiration. You don’t have to read the whole study, the abstract itself is interesting enough.

So, what do you think? Do you know of any studies that produced different results? Considering how many people report strong compensatory sweating after ETS, the results of linked study are barely a surprise… I understand there can’t be tons of these studies, because there aren’t that many people who underwent ETS, but still I wish there was even more scientific evidence, to get this mystery solved once and for all – what exactly does ETS do to your body?
