Cold sweats from drinking alcohol may be related to the amount of alcohol consumed, the duration of drinking and individual differences in tolerance to ethanol.
Ethanol easily enters the nerve cells of the brain and has an euphoric effect in small doses, but as the concentration of ethanol in the blood rises, it can have an inhibitory effect on the central nervous system, resulting in symptoms such as uncoordinated muscle movements, slurred speech, unsteady gait and even coma, accompanied by nausea, vomiting, drowsiness and cold sweats.
In addition, the body becomes dependent on ethanol after prolonged drinking, and if you stop drinking or drink less alcohol, you can experience sympathetic excitement such as cold sweats and muscle tremors.
