The hormone primarily responsible for sweating is acetylcholine.
Acetylcholine is a neurotransmitter that plays a crucial role in the nervous system, including the regulation of muscle contractions and the transmission of signals between nerves and glands.
When your body temperature rises, your brain sends signals to the sweat glands through your nervous system. Acetylcholine is released at the nerve endings, triggering the sweat glands to produce and release sweat.
This process helps to cool your body down by evaporating the sweat from your skin.
While acetylcholine is the main driver of sweating, other factors can influence your sweat production, such as stress, anxiety, and certain medications.
