<s>[INST] Last night i woke up to a wet spot in my bed...i had only been sleeping an hour and the reason i woke was that my daughter was crying.  The wet spot had no urine smell but i cant understand how i could have sweat that much that fast and in my groin area.  37 male never happened before....not sure what happened [/INST] Causes of Groin Sweating:Sweating in the groin area, also known as groin hyperhydrosis, has no specific cause currently identified. The reasons behind excessive sweating (hyperhidrosis) lie within the physiological make-up of a person. The main trigger is considered to be the over-action of the sympathetic nervous system (the section of our nervous system that governs the fight-or-flight response). Hot weather and an active lifestyle also lead to increased instances of groin sweating, but this is just our bodies natural reaction. Obesity can also contribute to the problem. </s>
