Finding a drink that genuinely helps you sleep can feel confusing. You hear that warm milk is soothing, herbal teas are relaxing, and cherry juice might boost melatonin. When you are tired and wide awake at 2 a.m., you just want to know what actually works and what might keep you up.
Below, you will learn what drink is good for sleep, how these beverages work in your body, and which ones you may want to avoid in the evening. You will also see how to build a simple nighttime drink routine that supports better rest.
How bedtime drinks support sleep
There are two main ways a bedtime drink can help you sleep.
First, certain ingredients have chemical effects on your brain and nervous system. Many herbal teas contain plant compounds that bind to receptors involved in anxiety and drowsiness. For example, some interact with GABA, a calming neurotransmitter that helps quiet overactive thoughts and prepares your body for sleep. Others contain melatonin or support your own melatonin production.
Second, sipping a warm, noncaffeinated drink can become a calming ritual. Doing the same simple steps each night, such as brewing tea or warming milk, signals to your brain that bedtime is coming. This behavioral routine can help you unwind even if the drink itself has only a mild physiological effect on sleep. A Cleveland Clinic overview notes that bedtime teas work through both sedative plant compounds and the relaxing habit of drinking them before bed (Cleveland Clinic).
The key is choosing drinks that support these effects instead of fighting against them.
Best herbal teas for better sleep
Herbal teas are some of the most popular nighttime drinks. Most are naturally caffeine free and fairly gentle, which makes them a good starting point if you want to experiment.
Chamomile tea
Chamomile is often the first answer to the question, "What drink is good for sleep?" This flower-based tea contains a flavonoid called apigenin, which binds to receptors in your brain that help reduce anxiety and increase drowsiness (Cleveland Clinic).
Research has linked chamomile tea to better sleep quality. A review cited by the Sleep Foundation found that chamomile may reduce awakenings during the night and improve overall sleep satisfaction, especially in older adults and postpartum women (Sleep Foundation). While it may not dramatically increase how long you sleep, it can make your sleep feel more restful.
Chamomile tends to be well tolerated. If you have allergies to plants in the daisy family, check with a healthcare provider first.
Lavender tea
You may already associate the scent of lavender with relaxation. You can also drink it as a tea. Lavender tea has been shown to help people feel more relaxed and fatigued at night and to decrease anxiety and depression symptoms, with some studies suggesting postpartum sleep benefits (Cleveland Clinic).
Sleep Foundation research notes that lavender tea might improve sleep quality and duration in the short term, although the measured benefits often fade after a few weeks (Sleep Foundation). That means it may be particularly helpful during a stressful period, such as after a major life event, rather than as a long term standalone solution.
Valerian root tea
Valerian root is one of the more potent sleep teas. It contains natural sedatives called valepotriates and sesquiterpenes, which may increase levels of GABA in the brain and promote calm.
Studies summarized by the Sleep Foundation found that nearly 90 percent of participants reported better sleep and faster sleep onset with valerian-based preparations and that it did not carry the same side effect profile as many prescription sleep medications (Sleep Foundation). A separate 2020 review of 60 studies supports valerian root as a generally safe and effective natural remedy for insomnia and sleep promotion (Healthline).
However, valerian tea can cause side effects for some people, such as vivid dreams, headaches, stomach upset, or morning drowsiness (Cleveland Clinic). Intermountain Healthcare also notes that valerian has mild addictive potential and should be used with care (Intermountain Healthcare). If you try it, start with a small amount on a night when you can sleep in and see how you feel the next day.
Lemon balm and passionflower
Lemon balm tea, made from a mint family herb called Melissa officinalis, is another calming option. Research summarized by the Sleep Foundation suggests it may ease insomnia symptoms and improve both anxiety and depression, with some studies reporting quality of life improvements similar to those seen with antidepressant medication (Sleep Foundation).
Passionflower tea contains flavonoids that act on benzodiazepine receptors in the brain, which may explain why it improves subjective sleep quality in some studies (Sleep Foundation). Passionflower combined with valerian in capsule form has also shown promise as a short term insomnia treatment, though this research used a more concentrated dose than a typical cup of tea.
If you are new to sleep teas, you might start with chamomile or lemon balm. If you need something stronger and your healthcare provider agrees it is safe for you, you could then explore valerian or passionflower blends.
Warm milk, almond milk, and "night milk"
Warm milk is one of the most traditional answers to what drink is good for sleep. The science behind it is more nuanced than simple bedtime stories suggest.
Regular warm milk
Milk naturally contains tryptophan, an amino acid that your body uses to produce serotonin and melatonin, two key players in regulating sleep and your circadian rhythm (Healthline). Because of this, warm milk is often recommended as a sleep aid and is thought to help with issues like insomnia and jet lag (Healthline and Intermountain Healthcare).
However, there is currently no strong evidence that a single glass of milk contains enough tryptophan or melatonin to significantly change your natural melatonin production or treat a sleep disorder on its own (Healthline). Experts suggest that the soothing effect may be as much about the comforting ritual and associations with childhood as about the nutrients themselves.
There is also no proof that warm milk is more effective than cold milk. Warm drinks in general tend to feel calming, and that may be why many people prefer warming their milk before bed (Healthline).
Almond milk
If you prefer a dairy free option, almond milk can be another drink that is good for sleep. It contains tryptophan, melatonin, and a notable amount of magnesium, about 17 milligrams per cup, which may help with muscle relaxation and sleep quality, especially in older adults (Healthline and Intermountain Healthcare).
Choosing an unsweetened version is important so that added sugar does not interfere with your sleep.
Night milk from evening-milked cows
You might also see references to "night milk," which is collected from cows at night instead of during the day. A 2015 study in mice found that night milk contained higher levels of tryptophan and melatonin than daytime milk, and that it produced sedative and anxiety reducing effects similar to the medication diazepam in several behavioral tests (Journal of Medicinal Food).
The same research showed that night milk shortened the time it took the animals to fall asleep and extended drug induced sleep duration, whereas day milk did not have these effects (Journal of Medicinal Food). Interestingly, EEG recordings suggested that night milk may help facilitate sleep rather than directly induce deep sleep changes.
These findings are promising, but they are based on animal models. Night milk products are not widely available, and the results may not translate directly to humans. If you come across such a product, you can consider it an experimental sleep drink rather than a proven treatment.
Green tea, ashwagandha, and other options
You may be surprised to see green tea on a list of drinks for sleep, since it usually contains caffeine. The key is choosing the right type.
Decaffeinated green tea
Green tea naturally contains L theanine, an amino acid that can reduce stress and improve sleep quality. Cleveland Clinic notes that L theanine may prolong sleep duration and make your rest more restorative (Cleveland Clinic). To get these benefits without stimulating your nervous system, you need a low caffeine or decaffeinated green tea.
Intermountain Healthcare highlights decaf green tea as a sleep friendly choice if you want a mild, relaxing drink that still feels more like a traditional tea than an herbal blend (Intermountain Healthcare).
Ashwagandha tea
Ashwagandha, a plant used in Ayurvedic medicine, is known for its adaptogenic properties. A 2021 study found that ashwagandha tea had a small but significant effect on improving sleep compared with placebo, particularly in people with insomnia or anxiety (Healthline).
In a 2024 Delish test of popular sleep drinks, ashwagandha tea caused noticeable sedation and made the taster feel extremely sleepy, matching some of the scientific evidence on its calming impact (Delish). Because ashwagandha can interact with certain medications and conditions, you should talk with a healthcare professional before using it regularly.
Tart cherry juice
Tart cherry juice is another option you might consider if you want a non tea drink. Intermountain Healthcare notes that studies published by 2010 found that about 16 ounces per day of tart cherry juice significantly decreased insomnia and helped regulate sleep cycles, likely because tart cherries are rich in melatonin (Intermountain Healthcare).
Some trendy sleep mocktails include tart cherry juice, magnesium, and added melatonin. However, personal testing in the Delish article found that a popular "Sleepy Girl Mocktail" did not actually induce sleep and instead caused jitteriness, despite cherry juice's known benefits (Delish). This highlights how individual responses and added ingredients can change your experience.
If you try tart cherry juice, aim for a pure, unsweetened version and watch your overall sugar intake.
Helpful rule of thumb: choose drinks that are caffeine free, low in sugar, and contain calming compounds like apigenin, L theanine, melatonin, or magnesium.
Drinks to avoid before bed
Knowing what drink is good for sleep also means knowing what to skip in the evening. Several common beverages can interfere with your ability to fall asleep, stay asleep, or get restorative deep sleep.
Alcohol
Alcohol can make you feel drowsy at first, which is why a nightcap is so tempting. However, it fragments your sleep later in the night. The American Academy of Sleep Medicine notes that alcohol increases nighttime trips to the bathroom, reduces REM sleep, worsens snoring and sleep apnea, and leads to more awakenings, even if you fall asleep quickly at first (American Academy of Sleep Medicine).
If you drink, try to keep alcohol away from your final hours before bed and keep your intake moderate.
Coffee, energy drinks, and soda
Caffeine is a powerful stimulant, and it stays in your system for hours. The American Academy of Sleep Medicine reports that consuming coffee six hours before bedtime can shorten total sleep time by about an hour and delay your internal clock (American Academy of Sleep Medicine).
Energy drinks contain even more caffeine than coffee or soda, which greatly impairs your ability to fall and stay asleep if you drink them later in the day (American Academy of Sleep Medicine). Soda combines caffeine with high sugar levels, which can both make it harder to fall asleep and increase night time awakenings (American Academy of Sleep Medicine).
For better sleep, switch to noncaffeinated drinks at least six hours before you plan to go to bed. Earlier is even better if you are sensitive to caffeine.
Too much water too late
Hydration supports your overall health and sleep, but timing matters. Drinking large amounts of water close to bedtime often leads to multiple bathroom trips during the night. Sleep experts recommend focusing on hydration earlier in the day and then reducing fluid intake in the hour or two before bed to limit sleep disruptions (American Academy of Sleep Medicine).
How to build a simple bedtime drink routine
Once you know what drink is good for sleep in theory, the next step is building a realistic habit that fits into your evening.
You can start small. About 60 to 90 minutes before your target bedtime, choose one calming, noncaffeinated drink. Boil water for chamomile or lemon balm tea, warm up a cup of unsweetened almond milk, or mix a half glass of tart cherry juice with water if you prefer something cool.
While you drink it, turn the moment into a transition ritual. Dim the lights, put your phone away, and do one quiet activity such as reading a physical book or stretching lightly. You are pairing the physiological effects of the beverage with environmental cues that tell your brain, "It is time to wind down now."
If you want to experiment, try one drink consistently for at least a week before switching to another. This gives you a better sense of how each option affects your body, instead of changing too many things at once.
Finally, if you have ongoing insomnia, are pregnant, take regular medications, or have health conditions such as kidney disease or sleep apnea, talk with a healthcare professional before adding new supplements or herbal teas. Many of these drinks are gentle, but it is still smart to make sure they are safe for your specific situation.
By choosing the right nighttime drink and turning it into a calming ritual, you give yourself another simple tool to support deeper, more restorative sleep.
