CBD for Sleep: Does it work?

UK Sleep Statistics

A 2020 survey revealed that 24.7% of UK citizens have been experiencing sleep deprivation since the COVID-19 pandemic. This figure is up from 15.7% previously1. Worldwide, studies have shown that the average prevalence of sleep deprivation is 10-30%, with some areas reaching as high as 50-60% 2 3 4.

Interestingly, a study in 2016 found that 33% of test subjects suffered from chronic insomnia, but only 27% of these people perceived themselves as a sufferer of insomnia5. With this in mind, sleep deprivation statistics may not give us an accurate picture of sleep quality worldwide because people aren’t aware that their situation is abnormal. 

Even so…If at least 1 in 4 of us are struggling with our sleep, that depicts a significant problem and from looking at the figures, it is only getting worse. Life doesn’t appear to be slowing down, so many are looking to CBD as a way to switch off at night.

Can CBD help with sleep?      


The sleep inducing effects of the cannabis plant have been known for centuries, with documented research on the subject dating back to the 1800s6 7 8 9. CBD is an abbreviation for cannabidiol, one of the naturally occurring compounds in cannabis responsible for these hypnogenic effects10. CBD is now legal in most parts of the world and has gained popularity as a potential solution to the sleep issues one quarter of us are reporting. CBD is particularly attractive to consumers because it exhibits many of the positive effects of the cannabis plant without the ‘high’ or any of the psychotropic side effects11.

Aligned with ever-growing public interests, scientists around the world have contributed to a volume of research into the use of CBD for sleep. At this point, it is difficult to find a single study which denies CBD helping with sleep…we tried. 

One study showed that 66.7% of subjects reported improved sleep within the first month of consistent CBD use, with “no evidence of a safety issue that would limit future studies”12. This is one of many studies illustrating that using CBD for sleep is an effective, natural and safe solution13 14.

3 Sleep Disorders and CBD

3 of the most common sleep disorders are15

  1. Insomnia
  2. Sleep Apnea 
  3. Narcolepsy 

Insomnia and CBD

Insomnia can come about at any point in life, for a long list of reasons. In 2015, one case study followed the experiences of a 10 year old girl, to find out the “Effectiveness of Cannabidiol (CBD) Oil for Pediatric Anxiety and Insomnia as Part of Posttraumatic Stress Disorder”.  For this particular girl, pharmaceutical medication had failed her and caused major side effects, but a trial of cannabidiol oil resulted in a “maintained decrease in anxiety and a steady improvement in the quality and quantity of the patient’s sleep.” These benefits occurred with a daily dosage of 12-25mg and the patient did not voice any complaints of side effects or discomfort due to the use of CBD. This particular CBD case study provides clinical data showing that cannabidiol (CBD) effectively improves sleep in a sufferer of insomnia. Further to this particular study, there are multiple non-clinical studies and reviews which conclude CBD may be an effective sleep treatment17 18

Sleep Apnea and CBD

Sleep apnea is a disorder characterised by “repetitive pauses in breathing during sleep caused by airway occlusion (obstructive sleep apnoea) or altered control of breathing (central sleep apnoea)” 19. Research has been carried out into the effect of cannabis treatments as a solution to sleep apnea, with mixed results, but there is insufficient research to make any claims about CBD’s specific interaction with symptoms of sleep apnea 20 21. When we can answer the question ‘can CBD help sleep apnea?’, our readers will be the first to hear about it so make sure you keep checking back!

Narcolepsy and CBD

Narcolepsy is a lifelong sleep disorder associated with symptoms of overwhelming daytime drowsiness and uncontrollable sudden attacks of sleep. Some people also experience further problems such as cataplexy (sudden muscle weakness), hallucinations and sleep paralysis 22. Interestingly, although CBD has been shown to help people get to sleep, it also exhibits enhanced daytime wakefulness in some test subjects 23. If specific administration of CBD could be clinically proven to promote wakefulness, it will likely deliver great benefits to sufferers of daytime exhaustion as a result of narcolepsy.

How does CBD help sleep?

Our body has something called the endocannabinoid system (ECS), which is responsible for maintaining a general level of stability and balance in our body, through the regulation of important well-being factors such as sleep24. CBD enhances the function of the endocannabinoid system and this is one of the main supposed reasons for its hypnogenic effects25. Also, CBD’s other capabilities may lead to easier sleep. For example, a CBD induced reduction in anxiety and inflammation is bound to help subjects doze off when the time comes.

CBD Oil Dosage For Sleep

The majority of cited studies found CBD to have a positive effect on sleep based on daily usage, but dosage amounts and timings vary from study to study. The UK government recommended that daily dosage does not exceed 70mg, but hypnogenic benefits have been shown in studies at levels of 70mg or less.
