Sleep & Relaxation

As classified by Western medicine, sleep disorders encompass a range of conditions that detrimentally impact sleep quality, timing, and duration, leading to diurnal stress and functional impairments (World Health Organization, Sleep Disorders Guidelines). These disorders may co-occur with other physiological or psychological conditions, serving either as symptoms or etiological factors. The spectrum includes conditions such as Insomnia, Narcolepsy, and Circadian Rhythm Disorders, as validated by the U.S. Food and Drug Administration (FDA) and clinical research (Journal of Sleep Research, 2020).

In contrast, Traditional Chinese Medicine (TCM) attributes sleep disorders to imbalances like empty heat or fire caused by yin deficiency, leading to various insomnia types (National Institute of Health, Complementary Medicine Review). The United States Department of Agriculture (USDA) has also conducted research on the nutritional aspects influencing sleep disorders.
