What is the principle behind bedwetting when hands are placed in hot water?

The reason why putting your hands in hot water causes bedwetting is due to oversensitivity of the nerves, or mental and psychological factors. You need to go to the hospital for relevant examinations in time to determine the cause and then make targeted treatment.

1. Nerve oversensitivity: Putting your hands in hot water before going to bed at night will dilate the blood vessels in the fingers, increase blood circulation and stimulate local nerves. After the nerve sensitivity increases, systemic nerve dysfunction will occur, and there will be overexcitement of the bladder nerves and bed-wetting. Bed-wetting will occur uncontrollably. Bed-wetting after contact with water is a normal physiological phenomenon and does not require special treatment. It is best not to drink a lot of water or come into contact with water before going to bed at night.

2. Mental factors: High mental stress or severe mental trauma can cause serious harm to the body and neurological disorders. Putting hands in hot water may cause excessive tension or nervous system disorders, leading to bedwetting.

3. Psychological factors: Excessive psychological tension and anxiety will cause abnormalities in the nervous system and uncontrolled urination after contact with water in a state of excessive anxiety. It is necessary to go to the hospital for a psychological evaluation in time to determine the cause and severity. Under the guidance of a doctor, psychological counseling should be carried out through language communication, or anti-anxiety drugs should be taken.
