Ayurveda views sleep as essential to health and life. It recognizes the importance of harmonizing the biological clock with the natural daylight cycle. Disrupting this harmony through night awakening or daytime sleeping can increase doshas and cause disease. Ayurveda recommends treatments for insomnia like head massage with oil, milk consumption, and practices that promote relaxation and kapha. These treatments aim to soothe vata, increase kapha, and establish rhythmic sleeping in tune with natural light and darkness.
