Night Sweats and Waking Up Damp? Hidden Signs of Autonomic Imbalance

Have you ever woken up feeling damp and cold, realizing you've broken into a sweat? Your pillow and blanket are soaked, and your clothes are clinging to your body. Even when it's not summer, if you have to wash your bedding every night during winter, it's not just a bad sleeping habit or high room temperature. Night sweats, often dismissed as a constitutional trait, can be a warning sign from your autonomic nervous system.

💡 [Key Answer] 3 most common causes of night sweats: ① Autonomic Imbalance: The body's temperature control center malfunctions, secreting sweat unnecessarily. ② Stress and Overwork: The sympathetic nervous system remains overactive, preventing the body from resting. ③ Poor Sleep Quality: Unstable sleep patterns further disrupt the autonomic nervous system. Dalimchae Clinic creates an environment where the body can rest comfortably through autonomic stabilization treatment.

In Korean medicine, sweating while asleep is called 'Dohan' (盗汗), meaning 'sweat that flows stealthily like a thief.' It characteristically occurs when asleep and stops upon waking. While many think it's just 'running hot,' sweat secretion is precisely regulated by the autonomic nervous system. If this balance is broken, the body may malfunction, secreting sweat even when it's not overheating.

The autonomic nervous system consists of the sympathetic (accelerator) and parasympathetic (brake) systems. At night, the parasympathetic system should be active for rest. However, due to stress or overwork, if the sympathetic system remains active, the body stays in a state of tension. This affects the brainstem's temperature regulation center, causing unnecessary sweating. This creates a vicious cycle that further degrades sleep quality.

Night sweats often accompany other symptoms like insomnia, chronic fatigue, headaches, dizziness, indigestion, and palpitations. Many patients in Incheon visit Dalimchae Clinic because they can't find a specific cause in general hospitals. This is often due to a hidden autonomic imbalance.

Korean medicine views 'Dohan' as an imbalance of Yin and Yang, or Qi and blood. It often occurs in a state of 'Yin deficiency and internal heat' (陰虛內熱). Dalimchae Clinic focuses on restoring autonomic balance and cooling the nervous system—a process called 'Suseunghwagang'—to help the brain rest and normalize temperature regulation.

Research published in Dove Medical Press (2026) showed a 66-year-old patient's chronic hyperhidrosis was completely resolved after 42 days of herbal treatment (Samhwangsasim-tang). Another study in 2021 reported an 80% improvement in chronic hyperhidrosis within 6 weeks using herbal medicine after diagnosing sympathetic overactivity.
