Sympathetic system controlls sweating (if u hav doubt over it then refer book). Anyone can explain why atropine which is parasympatholytic inhibits sweating & cause hyperthrmia in overdose.

M3 receptors are involved thermoregulation (sweat production), salivation and lacrimation. It is parasympathetic.

(source - my study notes)
Any textual source which mentions otherwise?

My dear brother,
fact is that though these r innervated by sympathetic system the neurotransmitter is Ach at these sites so they rblocked by atropine.

i will answe you simply

the sympathetic nervous system control sweeting . i agree with you but there is exception in the regard of sweeting .the postganglionic sympathetic fibres supplying the sweetglands are cholinergic not adrenergic as usual and so secretes ACH acting on M3 cholinergic receptors in the sweet glands so atropine which blocks all the types of muscarinic receptors including M3 receptors reducing sweeting
