What are Hot Flashes and Night Sweats?

Nocturnal Sleep hyperhidrosis is commonly known as the 'night sweats', and is a result of the occurrence of excessive sweating during sleep.

Although its ultimate cause is unclear, it is thought that changes in the levels of two hormones (Follicle-stimulating hormone (FSH) and Luteinizing hormone (LH)) are thought to play a major role in the process, just as they do in the case of hot flashes.

A deficiency in estrogen may be triggered by a variety of causes and is regarded as the prime cause of experiencing excessive heat, reddening/blotchiness of the skin, and perspiration.

Though many people sweat during their sleep, night sweats fall into a more extreme category, going beyond simply being too hot because of warm bedding. If a person wakes up with their pajamas and bedding soaked in sweat, even when the sleeping environment is cool and comfortable, then this is a strong indicator of night sweats.
