It is important to understand that there are many reasons why excessive night-time perspiration occurs. Not all causes are pathological and some are due to a normal change in life.How sweating occursSweating (hidrosis) in normal conditions occurs to cool the body. A signal sent to the sweat glands in the skin causes the release of sweat, which cools the body to prevent overheating.The nervous system plays a crucial role in the process of sweating. Details on the process of sweating are described below:Sensory receptors called thermoreceptors detect temperature changes and send signals to the hypothalamus in the brain.The hypothalamus then sends signals down the spinal cord to the peripheral nerves.These nerves activate the sweat glands to release the sweat.There is a feedback mechanism in which sweat production is halted once the hypothalamus detects that body temperature is in the normal range. for more :- https://myacare.com/blog/what-causes-night-sweats
