Night Sweats: Discover the Top 10 Causes of This Common Sleep Disruptor

Night sweats, or excessive sweating during sleep, can be more than just an uncomfortable nuisance. They often signal underlying health issues or lifestyle factors that disrupt restful sleep. Understanding the causes can help you address the problem effectively.

What Are Night Sweats?

Night sweats refer to episodes of excessive sweating during the night that soak your sleepwear and bedding. Unlike normal sweating due to a warm room, night sweats are often linked to medical conditions or hormonal changes.
