Ashwagandha, an ancient Ayurvedic herb, has gained scientific attention for its potential benefits on sleep quality and sleep disorders. The science behind its sleep-enhancing properties primarily revolves around its adaptogenic and anxiolytic effects.
As an adaptogen, Ashwagandha helps regulate cortisol levels, the hormone responsible for the body’s stress response. High cortisol levels, particularly in the evening, can significantly disrupt the sleep cycle, making it difficult to fall asleep or stay asleep. By reducing cortisol, Ashwagandha promotes relaxation and helps the body maintain a healthy sleep pattern.
Furthermore, Ashwagandha’s anxiolytic effects contribute to its sleep benefits. The herb increases the levels of gamma-aminobutyric acid (GABA), a neurotransmitter that plays a key role in inducing relaxation and reducing anxiety. Higher GABA levels have been linked to improved sleep quality and reduced insomnia symptoms.
Ashwagandha also contains tri ethylene glycol, a compound found to enhance non-rapid eye movement (NREM) sleep, which is essential for body restoration and overall sleep quality.
Additionally, the herb has been observed to improve sleep onset latency—the time it takes to transition from wakefulness to sleep. This effect is particularly beneficial for individuals with sleep disorders such as insomnia.
In summary, the science behind Ashwagandha and sleep is rooted in its adaptogenic, anxiolytic, and sleep-inducing properties. By regulating cortisol, increasing GABA levels, and enhancing NREM sleep, Ashwagandha contributes to a more restful and rejuvenating sleep experience.
