The Link Between Ashwagandha and Better Sleep

Ashwagandha has become one of the most popular natural remedies in modern wellness, and one of the key reasons is its potential to support better sleep. Known for its adaptogenic properties, this ancient herb has been used for centuries in Ayurvedic medicine to help the body cope with stress and restore balance. In the UK, more people are now turning to ashwagandha supplements, including gummies and capsules, as an alternative to synthetic sleep aids. But how exactly does it work, and can it really help you sleep better?

Ashwagandha in Ayurvedic Medicine

In traditional Ayurveda, ashwagandha is known as a rasayana, a rejuvenating herb used to strengthen both body and mind. Its name translates to “the smell of a horse,” which symbolises the vitality and strength it was believed to impart. Sleep was always a central part of Ayurvedic wellbeing, and ashwagandha was often prescribed to those suffering from insomnia or restlessness caused by stress or nervous exhaustion.

Ayurvedic practitioners understood that poor sleep is often a symptom of imbalance, particularly within the Vata dosha, which governs movement and the nervous system. Ashwagandha was said to help calm excessive Vata energy, allowing for deeper rest and rejuvenation. Mixed traditionally with warm milk or ghee before bedtime, it was used to relax the body and quiet the mind.

Modern Science and Sleep Research

In recent years, ashwagandha has become the focus of numerous scientific studies exploring its role in sleep regulation and stress reduction. Much of its benefit is linked to its adaptogenic nature, meaning it helps the body adapt to physical and mental stress. Chronic stress can lead to elevated levels of cortisol, the primary stress hormone, which disrupts the body’s natural sleep cycle.

Ashwagandha appears to help regulate cortisol production and support balance in the hypothalamic-pituitary-adrenal (HPA) axis, which plays a central role in stress response. By moderating this system, the body is better able to relax and transition into deeper stages of sleep.

Several clinical studies have found that ashwagandha root extract may improve sleep quality and reduce the time it takes to fall asleep. For example, research published in the Cureus Journal of Medical Science found that adults taking ashwagandha extract for eight weeks experienced significant improvements in sleep efficiency, sleep latency, and overall sleep quality compared to those taking a placebo. Participants also reported feeling more alert and refreshed upon waking.

How Ashwagandha Affects Sleep Chemistry

Ashwagandha contains active compounds known as withanolides, which contribute to its adaptogenic and calming properties. These compounds are thought to influence neurotransmitters in the brain, including GABA (gamma-aminobutyric acid), which helps quiet neural activity and promotes a state of calm.

By enhancing GABAergic activity, ashwagandha may have a mild sedative effect that supports the onset of sleep without causing grogginess or dependency. This is why many people prefer it as a natural alternative to over-the-counter sleep aids. Additionally, ashwagandha’s antioxidant properties help reduce oxidative stress, which can also interfere with restorative sleep.

Ashwagandha and Stress Reduction

A significant part of ashwagandha’s sleep benefits comes from its effect on stress. Elevated cortisol levels not only make it harder to fall asleep but can also cause you to wake up during the night. By supporting cortisol balance, ashwagandha helps stabilise energy levels and encourages a natural circadian rhythm.

People who take ashwagandha often report feeling calmer during the day and more relaxed in the evening. This emotional steadiness contributes to better sleep hygiene, as a calm mind is far more conducive to rest.

Ashwagandha for Insomnia and Restlessness

For those who struggle with insomnia, especially when it is linked to anxiety or overthinking, ashwagandha may help by promoting relaxation without sedation. Unlike some pharmaceutical sleep aids, it does not suppress the nervous system or alter REM sleep patterns. Instead, it encourages the body’s natural ability to relax and reset.

Ashwagandha’s holistic action may also help reduce muscle tension, racing thoughts, and restlessness at night. Some people find that taking it consistently for several weeks produces the best results, as adaptogens tend to work gradually, supporting long-term balance rather than providing immediate effects.

How to Take Ashwagandha for Sleep

Ashwagandha can be found in several forms, each with its own benefits. Powders can be mixed into warm milk or smoothies, capsules offer precise dosing, and gummies provide a pleasant and easy way to take it before bed.

The ideal time to take ashwagandha for sleep is usually in the evening, around one to two hours before bedtime. Taking it with a small snack or warm drink can improve absorption and enhance its calming effects. Consistency is important, as benefits often build over time with daily use.

If you are using ashwagandha for stress management as well as sleep, some people choose to take it twice daily once in the morning to support energy and focus, and again at night to promote relaxation. However, it’s best to follow product-specific guidance or consult a qualified herbalist or nutritionist for personalised advice.

Potential Benefits Beyond Sleep

While ashwagandha’s calming and sleep-promoting qualities are well known, it also offers other benefits that indirectly support better rest. By reducing anxiety, supporting mood balance, and enhancing resilience to stress, it helps create the conditions necessary for healthy sleep.

Studies have also explored its impact on thyroid function, energy levels, and hormonal balance. Improved hormonal health can contribute to steadier sleep cycles and reduced fatigue. Furthermore, ashwagandha’s support for immune and metabolic function may enhance overall vitality, leading to deeper, more restorative rest.

Are There Any Risks or Side Effects?

Ashwagandha is generally considered safe for most adults when used at recommended doses. However, as with any supplement, individual responses may vary. Some people may experience mild digestive discomfort, drowsiness, or slight changes in appetite when first starting it.

It’s important to avoid exceeding the suggested dosage and to check with a healthcare professional before use, especially if you are pregnant, breastfeeding, or taking thyroid or blood pressure medication. Because ashwagandha can support relaxation, combining it with other sedative herbs or medications should be approached with caution.

Ashwagandha and Modern Wellness

In the modern UK wellness landscape, ashwagandha has become a leading adaptogen because it provides both energy and calm, an unusual combination. This dual effect makes it appealing not just for sleep but also for managing everyday stress, enhancing focus, and improving emotional resilience.

With more people seeking natural ways to unwind, products such as ashwagandha gummies and drinks are becoming increasingly popular. These modern forms make it easy to incorporate traditional herbal wisdom into a busy lifestyle.

Conclusion

Ashwagandha’s reputation as a natural sleep aid is well deserved. By reducing stress, balancing hormones, and promoting calmness, it supports the body’s natural ability to rest and recover. Rather than forcing sleep, it nurtures the internal balance that makes restful nights possible.

Whether you choose to take it as a powder, capsule, or gummy, consistency and quality matter most. Look for standardised extracts with verified withanolide content and follow recommended guidance for best results.
