What Research Says About CBD and Sleep
Key Takeaway
The relationship between CBD and sleep is more nuanced than most CBD marketing suggests. The research is promising but the picture is complex. Here is what the science actually shows.
Key Sleep Studies
The Permanente Journal, 2019
72 adults with anxiety and poor sleep. 66.7% reported improved sleep scores in the first month. However, scores fluctuated over time, suggesting the sleep benefit may be dose-dependent or related to anxiety reduction.
Medicines Journal, 2018 (Review)
Reviewed existing literature and found preliminary evidence that CBD may have therapeutic potential for insomnia. Noted that CBD at different doses may have different effects, with higher doses being more sedating.
Journal of Clinical Pharmacology, 1981
An older but frequently cited study found that 160mg CBD significantly increased total sleep time compared to placebo. Participants also reported fewer sleep interruptions and better subjective sleep quality.
Frontiers in Pharmacology, 2018
Animal studies suggest CBD may interact with specific receptors involved in the sleep-wake cycle, including serotonin (5-HT1A) and adenosine receptors.
An important nuance: lower CBD doses (15-25mg) may actually promote wakefulness in some people, while higher doses (150mg+) tend to promote sleep. This dose-dependent relationship is why some people try CBD for sleep at low doses and conclude it does not work, when a higher dose might be effective.

CBD does not appear to work like a traditional sleeping pill that simply sedates you. Instead, research suggests it may improve sleep through several indirect and direct pathways.
Reduces Anxiety
Racing thoughts are one of the most common causes of insomnia. By reducing anxiety, CBD may remove the mental barrier that keeps you awake. Research on CBD for anxiety is stronger than for sleep directly.
May Reduce Pain
Physical discomfort is another major sleep disruptor. CBD's potential anti-inflammatory and pain-modulating properties may help people who cannot sleep due to chronic pain or tension.
Serotonin Interaction
CBD activates the 5-HT1A serotonin receptor, which plays a role in sleep-wake regulation. This same receptor is involved in the body's natural transition from wakefulness to sleep.
Cortisol Reduction
One study found that 300-600mg CBD significantly reduced cortisol levels. High cortisol at night is a known cause of insomnia and night waking, so cortisol reduction may directly improve sleep.
CBD vs THC for Sleep
| Factor | CBD | THC |
|---|---|---|
| Helps fall asleep | Higher doses may help | Yes, commonly used for this |
| Sleep onset speed | Gradual | Faster, especially indica strains |
| REM sleep | May support normal REM | May reduce REM sleep |
| Deep sleep | Research is limited | May increase deep sleep |
| Next-day grogginess | Rare | Possible, especially at higher doses |
| Tolerance buildup | Less common | Can develop with nightly use |
| Impairment before bed | None | Yes (intoxicating) |
| Dream recall | Normal | Often reduced (suppressed REM) |
Many people find the best sleep results from combining CBD and THC in a CBD-dominant ratio. Products with 5:1 or 3:1 CBD:THC ratios may offer THC's sleep onset benefits while CBD reduces the risk of next-day grogginess and supports more natural sleep architecture. Our best strains for insomnia guide covers strain options in detail. Also explore our CBN sleep guide for another cannabinoid gaining attention for sleep.

Get DirectionsCBD vs Melatonin for Sleep
When to Choose CBD
- Anxiety keeps you awake (racing thoughts, worry)
- Physical tension or pain disrupts sleep
- You want something you can also use during the day
- Melatonin has not worked for you
- You prefer a multi-pathway approach to sleep
When to Choose Melatonin
- Jet lag or time zone adjustment
- Shift work disrupting your schedule
- Circadian rhythm is off (falling asleep too late)
- You need help with timing, not anxiety or pain
- You prefer a supplement with more established dosing
These are not mutually exclusive. Some CBD sleep products include melatonin for a combined approach, addressing both the timing signal (melatonin) and the anxiety or tension barrier (CBD). If you try this combination, start with a low dose of each and adjust one variable at a time so you know what is actually helping.
CBD Sleep Dosing Guide
Recommended Approach
Week 1
50mg
30-60 min before bed. Use sublingual tincture for faster onset.
Week 2
75mg
If no improvement, increase. Same timing.
Week 3
100mg
Continue increasing if needed. Most people find their sweet spot between 50-150mg.
Week 4
100-150mg
Stabilize at effective dose. Note that research used 160mg as an effective sleep dose.
Important Dosing Note
Best CBD Products for Sleep
CBD Tincture (Full-Spectrum)
Fastest sublingual absorption. Easy to adjust dose precisely. Best for people who want to find their exact effective dose.
CBD + CBN Gummies
CBN is another cannabinoid with potential sleep-promoting properties. Products combining CBD and CBN may be more effective for sleep than CBD alone.
CBD + Melatonin Gummies
Addresses both sleep timing (melatonin) and sleep barriers (CBD anxiety/tension reduction). Convenient single product.
CBD:THC Ratio Products (5:1)
For people who find CBD alone insufficient. Small amount of THC helps with sleep onset while CBD dominates the formula.
Building a CBD Sleep Routine
CBD works best as part of a consistent sleep routine, not as a standalone fix. Here is a framework that integrates CBD with evidence-based sleep hygiene.
2 hours before bed
Stop screens. Dim lights. Begin winding down. Avoid caffeine after 2pm.
60-90 min before bed
Take CBD gummies or capsules if using oral products. This gives them time to absorb.
30-45 min before bed
Take CBD tincture sublingually if using oil. Hold under tongue 60-90 seconds.
15 min before bed
Light stretching, reading, or breathing exercises. Cool bedroom to 65-68 degrees.
Bedtime
Consistent bedtime. Dark room. No phone. Let the CBD support your body's natural sleep transition.
Frequently Asked Questions
Does CBD help you sleep?
Research suggests CBD may help improve sleep, particularly when poor sleep is caused by anxiety, pain, or stress. A 2019 study in The Permanente Journal found that 66.7% of participants reported improved sleep scores in the first month of CBD use. CBD appears to promote sleep primarily by addressing the underlying causes of insomnia rather than acting as a direct sedative, though higher doses (150mg+) may have more direct sleep-promoting effects.
How much CBD should I take for sleep?
Research suggests higher CBD doses are more effective for sleep than lower doses. Most studies used 25-175mg, with 160mg showing significant improvement in one study. A good starting point is 50mg taken 30-60 minutes before bed. If that does not help after a week, gradually increase to 75mg, then 100mg. Some people need 150mg or more for noticeable sleep benefits. CBD tinctures taken sublingually allow for faster onset than gummies.
Is CBD or THC better for sleep?
Both may help with sleep through different mechanisms. THC tends to help you fall asleep faster and is commonly used for insomnia, but it may reduce REM sleep and can cause grogginess. CBD addresses anxiety and pain that keep you awake without altering sleep architecture as much. Many people find the combination most effective, with CBD-dominant ratio products (like 5:1 or 3:1 CBD:THC) offering sleep onset from THC and deeper rest from CBD.
Is CBD better than melatonin for sleep?
They work differently. Melatonin signals your brain that it is time to sleep and helps with sleep onset timing. CBD may help with sleep by reducing the anxiety, pain, or restlessness that prevents sleep. Melatonin is better for jet lag or circadian rhythm issues. CBD may be better when racing thoughts or physical tension keep you awake. Some products combine both for a multi-pathway approach.
When should I take CBD for sleep?
Take CBD 30-60 minutes before your target bedtime. Sublingual tinctures absorb faster (15-30 minutes) than edibles (30-90 minutes), so adjust timing accordingly. For gummies or capsules, take them 60-90 minutes before bed. Consistency matters. Taking CBD at the same time each night as part of a wind-down routine may improve results over time.
