Wake up sweaty, it s cold! Why did you suddenly break out in a cold sweat?

We often hear the saying "scared out of a cold sweat" in our daily life. So do people really break out in a "cold sweat"? Why do you break out in a "cold sweat"?

There are two types of diaphoresis: warm diaphoresis and mental diaphoresis. Warm sweating is due to the reflex sweat secretion activity caused by the warm effect on the thermoreceptors, this part of the sympathetic postganglionic fiber secretion transmitter is acetylcholine, warm sweating usually appears throughout the body, which is of great significance for the dissipation of human heat. However, some of the sweat glands on the face, hands and feet and armpits are innervated by adrenergic fibers, and when the mood is anxious, nervous and excited, it causes sympathetic-adrenergic nerve fibers to be excited, and sweating occurs in the palms, soles of the feet and face, which is psychogenic sweating, not caused by warmth.
