Drinking Cinnamon Water Before Bed

Partly: Drinking cinnamon water before bed can be a pleasant way to hydrate if it does not disturb your sleep or trigger reflux, but it is not proven to help you sleep. Evidence for a sleep effect comes from an animal study of cinnamon extract, not from people drinking cinnamon water. Keep the portion comfortable and move it earlier in the evening if it causes problems.

Is drinking cinnamon water before bed good for you?

Cinnamon water can fit into a bedtime routine if you enjoy the taste and tolerate it well. It supplies fluid, and plain cinnamon water does not contain caffeine or added sugar. Its value at bedtime, however, is mainly a matter of preference rather than a demonstrated sleep benefit.

In a 2022 study of rats with experimentally induced insomnia, cinnamon extract affected levels of hormones and neurotransmitters associated with sleep. The study did not test cinnamon water or show that people sleep better after drinking it. Animal findings cannot establish an effective bedtime drink or dose for humans.

There is no need to start drinking cinnamon water if your current routine works for you. If you try it, pay attention to whether the drink makes bedtime more comfortable or instead leaves you awake or uncomfortable.

What are the possible benefits before bed?

Hydration

Cinnamon water contributes to your fluid intake, just as plain water does. A flavored drink may be appealing if you find it easier to drink than plain water, but drinking it immediately before sleep is not necessary to get the hydration benefit.

If you are thirsty at bedtime, a modest serving may be more comfortable than forcing yourself to drink a large glass. You can also spread your fluid intake through the day so that bedtime is not your main opportunity to drink.

A simple, caffeine-free ritual

Preparing a cup of cinnamon water can be a calming part of winding down if you enjoy the flavor. That is a personal routine, not evidence that cinnamon acts as a sleep medicine. Avoid adding caffeinated ingredients if your aim is a caffeine-free bedtime drink.

Steeped infused water is very low in calories, usually under 10 kcal per glass. Sweeteners or other additions can change that, so plain cinnamon water is the simplest choice if you want to avoid added sugar.

Support for normal body functions

Hydration helps your body function normally, but cinnamon water does not provide a special overnight detox. The liver and kidneys do most of the body's detoxification, while the lungs and gut also help eliminate waste.

What are the downsides of cinnamon water before bed?

Sleep and bathroom trips

Drinking a lot of any fluid close to bedtime may leave you needing the bathroom during the night. If that happens, try a smaller serving or have cinnamon water earlier in the evening. It is the fluid and your individual response that matter; there is no proven bedtime amount that works for everyone.

Do not keep drinking it in the hope that cinnamon will overcome an existing sleep problem. If difficulty sleeping persists or affects your daytime functioning, speak with a healthcare professional rather than relying on a drink as a treatment.

Reflux or stomach discomfort

If you are prone to reflux, a drink close to lying down may be uncomfortable. Cinnamon may also irritate some people. Stop drinking cinnamon water or have it earlier if you notice burning, stomach discomfort or another unpleasant reaction.

Seek medical advice for persistent reflux or trouble swallowing. Chest pain, especially with shortness of breath or pain spreading to the arm or jaw, needs urgent medical attention rather than being assumed to be reflux.

Who should be careful?

Cassia cinnamon can contain more coumarin than Ceylon cinnamon; regular exposure to high amounts of coumarin can be a concern for the liver. The amount transferred into an infusion is uncertain, so a strong daily brew should not be assumed risk-free.

If you have liver disease, are pregnant or breastfeeding, or take medicines such as blood thinners or diabetes medicines, ask a healthcare professional before using cinnamon water regularly or in concentrated amounts. Stop if you develop signs of an allergic reaction, and seek urgent help for breathing difficulty or swelling of the face or throat.

When is the best time to drink cinnamon water?

There is no evidence-based best bedtime for cinnamon water. Choose a time that lets you enjoy it without waking to use the bathroom or feeling uncomfortable when you lie down. For some people that may be earlier in the evening; others may tolerate a small serving closer to bed.

You can make an infusion ahead of time and keep it refrigerated. This recipe makes more than one bedtime serving, so you do not need to drink the whole batch at once.
