8 Common Causes of Excessive Sweating

Sweating is a natural way to help the body cool down and regulate temperature when it is hot. It is very normal to sweat during the summer or after physical activity. However, many people may notice their dampened hands or soaked shirts regardless of the level of activity or weather. Excessive sweating, also known as hyperhidrosis, could be the reason. This medical condition can be uncomfortable but normally not a source of concern. Below are 8 common causes of excessive sweating that you should know.


Excessive sweating is a common issue in diabetic patients. In these individuals, low levels of blood sugar signal the nervous system to sweat more. Another reason is linked to the diet. People with diabetes may suffer from nerve damage caused by some specific foods. These cases tend to cause sweating only around the neck and head. Diabetes is also related to nocturnal hyperhidrosis or night sweats. This can be attributed to a signal of low blood sugar when the body regulates insulin during the night. [1]
