The Best Teas for Sleep

Few rituals are as calming as a warm cup of tea before bed. The simple act of preparing and slowly sipping a soothing brew can signal to your body that a long day is winding down – and for many people, that alone is enough to make falling asleep easier.

But some teas go further than ritual. Certain herbal infusions – sometimes called “sleepy time” teas – contain compounds that may actively promote relaxation, reduce anxiety, and support more restful sleep. While the scientific evidence is still developing and no tea is a guaranteed cure for insomnia, the findings so far are promising – and the tradition of using tea as a natural sleep aid stretches back centuries.

In this guide, we explore how tea can help with sleep, which teas have the most evidence behind them, and how to make bedtime tea part of a healthy nightly routine.

How Tea Can Help You Sleep

There are two main ways tea may support good quality sleep:

The ritual itself. Establishing a consistent nightly routine is one of the most effective strategies for improving sleep patterns. Brewing and drinking a cup of tea at the same time each evening creates a predictable wind-down signal that your brain learns to associate with rest – much like dimming the lights or putting away screens.

Bioactive compounds. Many herbal teas contain compounds that interact with the nervous system in ways that promote relaxation. The most commonly studied mechanisms include:

• GABA activation – Several herbs used in bedtime teas (including valerian, passionflower, and lemon balm) are thought to increase levels of gamma-aminobutyric acid (GABA), a neurotransmitter that reduces nervous system activity and promotes calm.
• L-theanine – Found in true teas from the Camellia sinensis plant (green, white, oolong, black), L-theanine promotes alpha brain wave activity associated with relaxed focus. While true teas also contain caffeine, low-caffeine or decaffeinated options can deliver L-theanine’s calming benefits without the stimulant effect.
• Mild sedative action – Certain herbs, including chamomile and lavender, have demonstrated mild sedative properties in studies, helping to reduce the time it takes to fall asleep.

It is worth noting that much of the research on sleep teas has used herbal extracts, herbal supplements, or concentrated preparations rather than brewed tea, and many studies are small or short-term. The evidence is encouraging but not yet conclusive. Bedtime tea is best viewed as one element of a broader approach to healthy sleep – not a standalone solution for serious sleep disorders. If you are experiencing persistent sleep difficulties, consult a healthcare provider.

7 Best Teas for Sleep

1. Chamomile Tea

Chamomile is the most well-known and widely studied bedtime tea. Made from the dried flowers of the chamomile flowering plant (Matricaria chamomilla), it has been used in traditional medicine for centuries to manage anxiety, stress, and insomnia.

The key compound behind chamomile’s calming effect is apigenin, a flavonoid that binds to GABA receptors in the brain and acts as a mild tranquilliser – reducing tension in the muscles and nervous system.

A review of 12 studies found that chamomile safely improved sleep quality, though it did not significantly affect severe insomnia. Another study found that women who drank chamomile tea daily for two weeks reported fewer sleep-related difficulties compared to a control group. The evidence is modest but consistent: chamomile is a safe, gentle option for anyone looking to improve their nightly rest.

2. Lavender Tea

Lavender tea is made by steeping the dried buds of the lavender flower in hot water, producing a fragrant purple brew with a distinctive floral flavour. Lavender has long been associated with relaxation – it is one of the most commonly used scents in aromatherapy for stress relief and sleep support.

Research on lavender aromatherapy has found that it can increase deep (slow-wave) sleep and improve next-day energy levels. One study involving postnatal women found that those who drank one cup of lavender tea daily for two weeks reported less fatigue than a control group, while another study found that lavender tea reduced symptoms of depression and anxiety in older adults.

The dual benefit of lavender tea is that you experience both the calming aroma and the ingested compounds. Taking time to breathe in the scent before each sip may enhance the relaxation effect.

3. Passionflower Tea

Made from the leaves of the Passiflora incarnata plant, passionflower tea has a mild, slightly earthy flavour with subtle floral notes. It is one of the more promising herbal options for sleep support.

Passionflower is thought to work by boosting GABA levels in the brain, which helps quiet nervous system activity. A review of nine studies found that passionflower preparations – including teas, syrups, and tinctures – may act as a natural sedative and help relieve anxiety.

In a study of 41 adults, those who drank one cup of passionflower tea nightly for one week reported significantly improved subjective sleep quality compared to a placebo group. While larger and more recent studies are needed, passionflower is a well-tolerated and pleasant addition to a bedtime routine.

4. Valerian Tea

Valerian root has been used as a natural remedy for sleep disturbances since at least the 2nd century. Sometimes simply called valerian tea, it is made from the dried roots of the Valeriana officinalis plant and has a distinctly earthy, woody flavour that some people find strong – blending it with chamomile or lemon balm can help soften the taste.

Valerian is believed to work by increasing GABA levels in the brain, similar to passionflower. Some studies have found that it can improve sleep quality, reduce the time it takes to fall asleep, and enhance feelings of calm. However, the evidence is mixed, and not all studies have shown significant effects.

A few practical notes: valerian root can interact with certain medications (particularly sedatives and anti-anxiety drugs), so consult your doctor before using it regularly. Some people also report that its effectiveness improves with consistent use over several weeks rather than as a one-off remedy.

5. Lemon Balm Tea

Lemon balm (Melissa officinalis) is a member of the mint family with a bright, citrusy flavour that makes it one of the more approachable bedtime teas. It has been used since the Middle Ages as a natural remedy for anxiety and insomnia.

Like passionflower and valerian, lemon balm is thought to work by stimulating GABA receptors, creating a sense of calm. Research suggests that lemon balm may be most effective when combined with other calming herbs – a blend of lemon balm and chamomile, for example, has been studied with positive results for mild insomnia.

Lemon balm is also easy to grow at home, making it a convenient option for those who enjoy fresh herbal infusions.

6. Peppermint Tea

Peppermint tea is caffeine-free, refreshing, and widely available – making it a popular evening choice even among people who do not specifically seek out sleep teas. While peppermint has not been studied as extensively as chamomile or lavender for sleep, it offers indirect benefits that can support a better night’s rest.

The menthol in peppermint acts as a natural muscle relaxant, which can help ease physical tension before bed. Peppermint is also well-regarded for supporting gut health and settling digestive discomfort – bloating, gas, and indigestion can all disrupt sleep, and addressing them before bed can make a meaningful difference.

For those whose sleep is affected by physical discomfort rather than anxiety, peppermint tea is a practical and pleasant option.

7. Low-Caffeine True Teas

While herbal teas are the most common choice for bedtime, there are true teas from the Camellia sinensis plant that can work well in the evening – provided the caffeine content is low enough.

The advantage of true teas is L-theanine, the amino acid that promotes calm, focused relaxation. Options to consider include:

• Decaffeinated green tea – retains much of its L-theanine content despite the decaffeination process, along with the antioxidant benefits of green tea. A study found that low-caffeine green tea was linked to improved sleep quality and reduced stress compared to regular green tea.
• Aged pu’erh tea – because pu’erh undergoes microbial fermentation and is often stored for years, its caffeine content decreases over time. A well-aged shou (ripe) pu’erh contains relatively modest caffeine and offers a warm, smooth, earthy character that many people find deeply comforting in the evening.
• Lightly brewed white tea – white tea brewed at a lower temperature for a shorter time can deliver a gentle, soothing cup with minimal caffeine.

If you are sensitive to caffeine, it is still best to enjoy these teas in the early evening rather than immediately before bed. For a full comparison of caffeine across tea types, see our guide on how much caffeine tea has compared with coffee.

Practical Tips for Bedtime Tea

Timing matters. Aim to drink your tea 30-60 minutes before you plan to sleep. This gives you time to enjoy the ritual, use the bathroom, and allow the calming compounds to take effect without the risk of waking up in the middle of the night.

Keep it simple. Avoid adding sugar or honey in large amounts – the blood sugar spike can work against your sleep goals. If you need a touch of sweetness, a small amount of honey is fine.

Build a routine. The sleep benefits of bedtime tea are strongest when it becomes a consistent habit. Choose a tea you genuinely enjoy the taste of, brew it at the same time each evening, and pair it with other wind-down activities like reading or gentle stretching. Reducing screen time and putting away electronic devices at least 30 minutes before bed can further reinforce the signal that it is time to rest.

Minimise fluid intake close to bed. If frequent nighttime bathroom trips are a concern, try to finish your tea at least one to two hours before bed and keep the serving to a single cup (around 200-250 ml).

Frequently Asked Questions

Which tea is best for sleep?

Chamomile has the most research behind it and is the safest, most widely recommended option. If chamomile does not appeal to you, lavender and passionflower are excellent alternatives with promising evidence. Many people find that blends combining two or three of these herbs work well.

Can tea cure insomnia?

No. Bedtime tea can help with mild sleep difficulties and is a useful part of a healthy sleep routine, but it is not a treatment for chronic insomnia or other serious sleep disorders. If you are consistently struggling with sleep, it is important to speak with a healthcare professional.

Are sleep teas safe during pregnancy?

Some herbal teas are generally considered safe during pregnancy (chamomile in moderate amounts, for example), but others – particularly valerian root – may not be recommended. Always consult your doctor before adding herbal teas to your routine during pregnancy or while breastfeeding.

Can I drink caffeinated tea before bed?

If you are not caffeine-sensitive, a very lightly brewed true tea or an aged pu’erh may be fine in the early evening. However, for most people, caffeine-free herbal teas are the safest choice within a few hours of bedtime. For more on tea caffeine levels, see our caffeine comparison guide.
