What is nocturnal hyperhidrosis?
Nocturnal hyperhidrosis is when you sweat excessively at night. It can cause your sheets to be damp with sweat and make your pillow wet. This can lead to feeling uncomfortable during the night, as well as waking up feeling sticky and uncomfortable.
What causes nocturnal hyperhidrosis?
- Excessive stress
- Some medications
- Hyperthyroidism (overactive thyroid)
“The Mayo Clinic” says that the most common cause of excessive sweating is an overactive sympathetic nervous system (SNS). The SNS regulates the body’s fight or flight response by increasing heart rate, constricting blood vessels, raising blood pressure and releasing adrenaline into the bloodstream.
