The sweat glands are controlled by your autonomic vervous system in which high adrenaline
state causes you to sweat.
.Emotionally induced sweating typically involves palms/soles/axilla areas. Your sweat glands maybe a bit sensitive to Adrenalin than usual, thus when anixous (adrenaline released/increased) you sweat more...If excessive, consult doc for treatment. Hope this helps.
