It is particularly easy to get nervous, and when you are nervous, you sweat. What to do?

1. Because sweat glands are located in different positions, with different properties and quantities, they have different responses to sensory and psychological stimuli and thermal stimuli. According to different types of stimulation, sweat secreted and excreted by sweat glands can be divided into warm sweating, mental sweating and taste sweating.

When people are nervous, their palms will sweat, which is mental sweating. The incubation period from stimulation to sweating is very short, only a few seconds to 20 seconds. Therefore, under the influence of mental factors such as nervousness, fear and excitement, nerve impulses spread from the cerebral cortex to the eccrine glands of the palm, and the concentration of acetylcholine increased, so that the secretion and excretion of eccrine glands increased rapidly in a short time, that is, palm sweating was produced.

3. Similarly, some experts believe that there is another mental sweating center, which is always in an excited state. In the case of being stimulated, reactive sweating will occur. Mental sweating is most obvious in the palm of your hand, but also in the back of your hand, head, neck, forearm and calf. When a few people are highly nervous, they may even sweat all over.
