Can Turmeric Affect Your Sleep?


Turmeric is a bright yellow spice that has been used for centuries in Indian cuisine and Ayurvedic medicine. More recently, turmeric has grown in popularity in the West due to its many purported health benefits. One question that often comes up is whether consuming turmeric can affect sleep.

Turmeric contains a compound called curcumin which is thought to be responsible for most of its beneficial effects. Curcumin has anti-inflammatory, antioxidant, and even anti-depressive properties. With all of these diverse effects, it's understandable that people wonder if turmeric can impact sleep as well.

Can Turmeric Affect Your Sleep

In this post, we’ll take an in-depth look at the evidence surrounding turmeric and sleep. Does turmeric help you sleep? Can it keep you awake? How much turmeric is too much before bedtime? Let's find out.

How Could Turmeric Affect Sleep?

Before looking at the research, it's helpful to understand the different ways turmeric could hypothetically impact sleep.

Turmeric contains compounds that can cross the blood-brain barrier and influence neurotransmitters like serotonin and dopamine. These brain chemicals play an important role in regulating our sleep-wake cycles. In theory, turmeric could increase levels of calming neurotransmitters, inducing a sedated effect.

On the other hand, curcumin may slightly boost brain-derived neurotrophic factor (BDNF), which plays a role in learning, memory and mood. Some experts speculate BDNF levels that are too high at night could lead to insomnia.

Finally, turmeric and curcumin are associated with gastrointestinal side effects like nausea, diarrhea or stomach pains when consumed in large amounts. These issues could certainly disrupt sleep.

Now that we have an idea of the potential mechanisms, let’s look at what studies actually show about turmeric’s effects on sleep.

Research Investigating Turmeric and Sleep

Surprisingly, there are very few studies that have directly analyzed the impact of turmeric on sleep in humans. However, the limited research available provides some clues.

Does Turmeric Act as a Sedative?

Some older animal research from the 1990s suggested turmeric can have sedative and sleep-enhancing effects:

  • In one study, mice given high doses of curcumin spent more time asleep. The researchers speculated curcumin’s anti-inflammatory properties contributed to the sedative effects.
  • Another study in rats found turmeric essential oil reduced spontaneous activity and promoted sleep.

However, these results in rodents and other animals don’t necessarily translate to humans. More recent studies suggest curcumin is unlikely to cause drowsiness in people, except perhaps at very large doses:

  • A trial on healthy adults found curcumin supplements up to 1 gram per day over 4 weeks did not cause any adverse effects on cognition or mood, indicating no sedative action.
  • Similarly, a study in the elderly found curcumin doses up to 4 grams per day did not negatively affect cognitive function or mood.

Overall, current evidence in humans indicates that standard supplemental doses are unlikely to have major sedating properties. But we can't completely rule out this possibility at very high intakes.

Can Turmeric Tea Help You Sleep?

Many natural health enthusiasts drink turmeric tea before bed, claiming it helps them sleep. Unfortunately, there is minimal formal research on turmeric tea for sleep.

However, we do know that warm beverages like chamomile or passionflower tea can promote sleep simply through the calming ritual of sipping a hot drink before bed. Theoretically, turmeric tea could provide the same benefit. Warm milk is also thought to boost levels of sleepiness-inducing tryptophan.

If turmeric tea relaxes your mind and body, it very well may result in better sleep quality, even without strong sedative properties. That said, more studies are needed to determine if turmeric tea has direct benefits for sleep compared to placebo.

Does Turmeric Keep You Awake?

Based on anecdotal reports, there is some concern that turmeric may overstimulate the brain and make it difficult to fall asleep. However, limited data is available to confirm or refute this idea.

Some supplements like vitamin B12, ginseng or guarana are known to occasionally cause insomnia in sensitive people. This is generally due to stimulant substances that activate the central nervous system.

Turmeric is not usually considered a stimulating herb, and no studies confirm it causes insomnia or anxiety at standard doses. However, its potential to slightly boost BDNF could theoretically interfere with sleep in some circumstances.

Overall, there is currently no strong evidence that turmeric disrupts sleep or causes insomnia, unless consumed in extremely large amounts. More research is needed to know for sure.

What Does The Research Say Overall?

Given the limited direct evidence, what conclusions can we draw about turmeric’s effects on sleep? Here’s a quick summary:

  • Animal studies suggest turmeric may have sedative and sleep-enhancing effects, but these results don’t always apply to humans.
  • Research in humans indicates curcumin is unlikely to cause drowsiness except possibly at very large doses exceeding 1 gram.
  • Turmeric tea could hypothetically promote sleep through relaxation, but more research is needed specifically on turmeric tea.
  • Despite anecdotal reports, there is currently no solid evidence that turmeric causes insomnia or disrupts sleep in standard supplemental doses.

In summary, turmeric appears unlikely to have major impacts on sleep – either positive or negative – for most people at normal intakes. However, some people may be more sensitive to potential subtle effects.

How Much Turmeric is Safe Before Bed?

So how much turmeric is too much to have before bedtime? Here are some general dosage guidelines:

  • Up to 500 mg curcumin from a supplement is unlikely to affect sleep for most people. This is equivalent to roughly 2,000 mg turmeric powder.
  • 1,000 mg curcumin or more may potentially cause slight drowsiness in sensitive individuals, but is still unlikely to have major sedative effects.
  • Very large doses over 4 grams of curcumin could affect cognition and mood, which might interfere with sleep. It's best to stay under this amount close to bedtime.
  • Drinking 1-2 cups of turmeric tea before bed is generally fine and may even promote sleep through relaxation.

Of course, some people may feel differently, so it’s best to pay attention to your own experience. Avoid taking turmeric/curcumin supplements within 2 hours before bedtime to play it safe.

Other Factors That Can Determine Turmeric’s Effects

A few other factors may help explain the mixed reports of turmeric’s effects on sleep:

1. Time of day

Consuming turmeric early in the day is less likely to affect sleep compared to taking a dose in the evening.

2. Individual differences

People have varying sensitivities to compounds that alter neurotransmitters and sleep cycles. Someone prone to insomnia may be more likely to notice sleep disturbances from turmeric compared to a heavy sleeper.

3. Dosage and concentration

Extracts delivering higher concentrations of curcumin are more likely to influence sleep than raw powdered turmeric, although dosage also matters.

4. Source and quality

The curcumin content of turmeric powder can vary greatly. Pure turmeric extracts may be more potent.

As with any supplement, your unique biology and dosage can affect results. Stay below suggested amounts and see how your body responds.

7 Tips for Using Turmeric to Improve Sleep

While more research is still needed, the following tips may help you take advantage of any potential sleep benefits from turmeric:

  1. Try turmeric tea: Sip turmeric tea 1 hour before bed for relaxation. Add anti-inflammatory ingredients like ginger or cinnamon.
  2. Take curcumin earlier in the day: In case higher doses are sedating for you, take supplements no later than mid-afternoon.
  3. Use turmeric milk: Golden milk combines anti-inflammatory turmeric with relaxing warm milk. Avoid adding sugar or caffeine.
  4. Add black pepper: Piperine in pepper boosts curcumin absorption. Combine pepper and turmeric in savory dishes or smoothies earlier in the day.
  5. Reduce inflammation: Chronic inflammation can impair sleep. Turmeric's anti-inflammatory properties may indirectly improve sleep over time.
  6. Limit doses: Stick to evidence-based doses and avoid ingesting turmeric/curcumin right before bedtime.
  7. Try other herbs: Magnolia, chamomile, passionflower and lemon balm are alternatives specifically shown to improve sleep.

Focus on anti-inflammatory recipes earlier in the day and soothing nighttime rituals for best results. Monitor effects carefully if trying higher therapeutic doses of curcumin.


Research on the sleep-related effects of turmeric is limited but indicates the following:

  • Animal studies show potential sedative and sleep-promoting effects, but human data is mixed.
  • Turmeric is unlikely to cause drowsiness except perhaps at very high doses over 1 gram of curcumin.
  • Despite anecdotal reports, there is currently no strong evidence turmeric causes insomnia or disrupts sleep at standard doses.
  • Sipping turmeric tea before bed may help relaxation and sleep through the calming ritual.
  • Stay under 500 mg curcumin near bedtime to avoid any possibility of interference with sleep cycles.
  • Pay attention to your own experience, as individuals can vary in sensitivity.

Incorporating turmeric into your diet and supplement routine has many potential anti-inflammatory and antioxidant benefits. With careful dosage timing, it’s unlikely turmeric will negatively impact your sleep quality. More research directly investigating turmeric’s effects may shed further light on this question.

Frequently Asked Questions

Does turmeric reduce inflammation that interferes with sleep?

Some research indicates turmeric's anti-inflammatory properties can reduce inflammatory cytokines and chronic inflammation. Since inflammation is linked to certain sleep disorders like insomnia, turmeric could indirectly improve sleep over time by lowering inflammation. However, this effect is still being investigated.

Is turmeric more likely to affect women's sleep?

Currently no evidence suggests turmeric affects sleep differently in men versus women. However, hormone fluctuations related to the menstrual cycle can impact women's sleep quality. Any compound that influences neurotransmitters and sleep cycles may interact with these hormonal changes. But more research is needed specifically on gender differences.

Can turmeric help with sleep apnea?

Sleep apnea is a condition where breathing stops temporarily during sleep. Curcumin has been researched for inflammatory conditions affecting respiratory function. In theory, it could help reduce inflammation contributing to apnea, but no studies confirm this effect. Don't use turmeric in place of standard apnea treatments without medical guidance.

Does turmeric keep you awake if taken at night?

Despite anecdotal reports of turmeric interrupting sleep, current evidence doesn't confirm this effect at commonly recommended dosages. However, everyone has different sensitivities. Pay attention to your own experience. Avoid curcumin supplements for several hours before bedtime just in case.

Can turmeric replace sleeping pills?

No, turmeric should not be used in place of prescription sleep medications unless approved by your doctor. Sleeping pills have stronger sedating properties. Turmeric may provide modest relaxation benefits when used in addition to doctor-approved treatments, but more research is still needed.

Does turmeric interact with any other medications?

Yes, turmeric can potentially interact with certain medications including blood thinners, diabetes drugs, stomach acid reducers, antidepressants and others. Be sure to consult your doctor before using turmeric if you take any medications, especially close to bedtime.

How long before bed should you avoid turmeric?

It's wise to avoid consuming large amounts of turmeric or curcumin supplements in the 2-3 hours before bedtime. This gives your body enough time to metabolize the compounds and prevent any potential disruption in your sleep cycles. Drink turmeric tea 1 hour or less before bed for the best relaxation benefits.

Is turmeric safe for children?

Turmeric is likely safe for children in small culinary doses. However, the use of turmeric/curcumin supplements in children is more controversial. Due to limited safety data, most experts recommend avoiding turmeric supplements for kids unless approved by a pediatrician. Always supervise children closely when consuming turmeric.

Does turmeric stain teeth yellow?

Yes, turmeric is prone to staining teeth, especially at high doses. Limit consumption close to bedtime and thoroughly brush/floss your teeth afterward. Avoid whitening treatments like bleaching right after using turmeric, as it can react and worsen stains. Discontinue use if stains become difficult to remove.

Can turmeric upset your stomach before bed?

In some people, large amounts of turmeric on an empty stomach can cause nausea, diarrhea or gastro-esophageal reflux. This could disrupt sleep. Start with low doses and take turmeric with food to minimize stomach upset. Stop using if it persistently causes discomfort.


Research into the effects of turmeric and its active compound curcumin on sleep is limited, but shows mixed results. Some initial studies in animals during the 1990s suggested turmeric may have sedative and sleep-promoting effects. However, more recent research in humans indicates standard supplemental doses of curcumin are unlikely to cause significant drowsiness or enhance sleep. While many people drink turmeric tea before bed claiming it helps them sleep, formal studies are still needed. Anecdotal reports of turmeric interrupting sleep are also not strongly supported by current evidence, unless consumed in extremely high doses over 1 gram of curcumin. The time of day, individual differences, dosage, and source of turmeric may also impact effects. More human research directly analyzing turmeric’s effects on sleep cycles and quality compared to placebo is needed. Current findings suggest incorporating turmeric in your routine is unlikely to negatively impact sleep for most people if taken earlier in the day at recommended dosages under 500 mg curcumin.
