Ashwagandha Extract Found To Improve Non-Restorative Sleep
Non-restorative sleep refers to the subjective feeling that sleep has not been sufficiently refreshing, and often occurs despite the appearance of normal sleep. People who experience non-restorative sleep wake up feeling tired even after extended periods of sleep and experience excessive daytime sleepiness. A recent study suggests that supplementation with ashwagandha extract may help improve sleep quality by reducing the amount of non-restorative sleep.
Participants in the study included 150 adults who scored high on non-restorative sleep measures. They were given 120 mg of ashwagandha extract or a placebo daily for 6 weeks. The researchers used the Restorative Sleep Questionnaire-weekly version and World Health Organization Quality of Life-Bref to evaluate sleep quality and non-restorative sleep. In addition, sleep actigraphy was used to measure the onset of sleep latency, sleep efficiency, total sleep time and wake after sleep onset.
Participants in the ashwagandha group reported a 72% increase in sleep quality, compared to 29% in the placebo group. The ashwagandha group also saw significant improvements in sleep efficiency, sleep latency, total sleep time, and wake after sleep onset compared to the placebo group. In addition, they saw significant improvements in quality of life scores in physical, psychological, and environmental areas.
The study was conducted by researchers from the International Institute of Sleep Sciences. It was published online ahead of print on March 21, 2020 in the journal Sleep Medicine.
