Introduction to Sleep and Recovery#
Sleep is a vital component of our daily lives, essential for physical recovery, mental health, and cognitive function. The National Sleep Foundation recommends that adults aim for 7-9 hours of sleep each night for optimal health. However, millions of people worldwide suffer from sleep disorders or insomnia, leading to significant impairments in quality of life and increased risk of chronic diseases like diabetes, cardiovascular disease, and obesity. Among the various strategies to improve sleep quality, herbal supplements such as valerian root and ashwagandha have gained popularity due to their perceived benefits and relatively safe profiles.
The Science of Sleep#
Understanding the science behind sleep can help appreciate how supplements like valerian root and ashwagandha might influence sleep patterns. Sleep is regulated by the body’s internal clock, or circadian rhythm, which responds to light and darkness to synchronize physiological processes with the 24-hour day-night cycle (Dolepski et al., 2025). The sleep-wake cycle is further divided into different stages, including non-rapid eye movement (NREM) sleep and rapid eye movement (REM) sleep, each serving distinct functions in restorative sleep and cognitive processing.
Evidence-Based Supplement Recommendations#
Both valerian root and ashwagandha have been studied for their potential to improve sleep quality. Valerian root, derived from the plant Valeriana officinalis, has been traditionally used for its sedative properties (N Shinjyo et al., 2020). A systematic review and meta-analysis found that valerian root could be a safe and effective herb to promote sleep, though the quality of evidence varied (N Shinjyo et al., 2020). More recent studies have supported these findings; for example, H Chandra Shekhar et al. (2024) demonstrated that standardized extract of Valeriana officinalis improves overall sleep quality in human subjects with sleep complaints.
Ashwagandha (Withania somnifera) is another herbal supplement that has been evaluated for its effects on sleep. Known for its adaptogenic properties, ashwagandha is believed to help the body cope with stress, potentially improving sleep quality (D Langade et al., 2021; A Deshpande et al., 2020). Clinical studies have shown that ashwagandha root extract can improve sleep quality and may be beneficial in managing insomnia (D Langade et al., 2021).
Product Recommendations#
When choosing between valerian root and ashwagandha for sleep improvement, it’s essential to consider the product’s formulation, dosage, and manufacturing quality. While specific product recommendations cannot be made without access to current market offerings, looking for products that adhere to good manufacturing practices (GMPs) and have third-party testing for purity and potency is crucial.

Practical Tips for Improving Sleep Tonight#
- Establish a Bedtime Routine: Engage in relaxing activities like reading or meditation before bed to signal the body that it’s time to sleep.
- Create a Sleep-Conducive Environment: Ensure your bedroom is dark, quiet, and at a comfortable temperature.
- Limit Screen Time Before Bed: The blue light emitted by smartphones, tablets, and computers can suppress melatonin production.
- Avoid Caffeine and Alcohol Close to Bedtime: Both can disrupt sleep patterns and reduce the quality of sleep.
- Consider Keeping a Sleep Diary: Tracking your sleep patterns can help identify factors that may be affecting your sleep.
Conclusion#
Valerian root and ashwagandha are both promising herbal supplements for improving sleep quality, with evidence supporting their safety and efficacy. While valerian root may offer more immediate benefits for falling asleep, ashwagandha could provide additional health benefits due to its adaptogenic properties. It’s crucial to consult with a healthcare professional before starting any new supplement regimen, especially if you have underlying health conditions or are taking medications.
