Hyperhidrosis of the upper body due to heat stimulation is a disorder of excessive sweat gland secretion in the upper body caused by heat stimulation and is commonly associated with night sweats. Hyperhidrosis is a disorder in which excessive sweat gland secretion is caused by sympathetic hyperexcitation. The sympathetic nerve governs sweating throughout the body. Under normal circumstances, the sympathetic nerve regulates body temperature by controlling sweating and heat dissipation. However, in hyperhidrosis, sweating and facial flushing are completely out of control. How can this symptom be prevented if it occurs? There are no better measures, but the main thing is to prevent related diseases. If there is a background of hereditary syndrome, preventive measures include the introduction of genetic counseling, carrier genetic testing and prenatal diagnosis and selective abortion to prevent the birth of affected children. Relax, pay attention to personal hygiene, bathe and change clothes regularly. You can eat more fresh fruits and vegetables to ensure the intake of vitamins.
