Primary focal hyperhidrosis makes the hands sweaty and is often genetically related. It is mainly a result of abnormalities in the nervous system in response to normal emotions or stress, or exaggerated central responses that cause the small sweat glands to secrete excessive sweat, mainly in the form of sweaty hands, feet and even armpits, which is usually genetically related, but decreases with age. When considering excessive hand sweating, the doctor helps to look for specific diseases, such as hyperthyroidism or febrile illnesses, and recommends topical treatments if these are not present. Topical and internal medications usually provide some relief, but the key is to live a healthy lifestyle, with reasonable and balanced nutrition, scientific and moderate exercise, abstinence from smoking and alcohol, and psychological balance. Pay attention to avoid spicy, stimulating foods and drinks, to adjust the mind, avoid emotional tension, emotional excitement, or even anger, sadness.
