Profuse sweating after bathing may be caused by physiologic factors, and is also considered to be related to diseases such as hyperthyroidism and autonomic dysfunction. 1. Physiological factors: the summer weather is hot, the temperature of the bath water is too high, the temperature inside the body gradually rises during the bath, the capillaries expand, and the sweat glands secrete sweat after the bath, which has the effect of dissipating heat and leads to sweating after the bath. Sweating caused by the above factors is a normal phenomenon, it is recommended to avoid catching a cold after bathing, otherwise it is easy to catch a cold. 2. Hyperthyroidism: the clinical manifestations are mainly caused by excessive circulating thyroid hormones, which can have symptoms such as fear of heat and excessive sweating, resulting in sweating after bathing. 3. Autonomic nerve dysfunction: Nerve dysfunction will have dizziness, headache, panic, palpitations (rapid heartbeat, often accompanied by panic), sweating, skin sensory abnormalities and other symptoms, which can also cause profuse sweating after taking a bath. There may be other reasons for profuse sweating after a bath. Sweating caused by physiological factors is a normal phenomenon. If you suspect that it is related to certain diseases, it is recommended to go to the hospital for examination and timely treatment.
