To understand whether CBD can improve sleep, we first have to understand what causes poor sleep.
If your insomnia is caused by external factors or related conditions, CBD may help by treating the causes of sleeplessness.
While research on CBD is still in its infancy, some research suggests that CBD can treat anxiety.
ResearchTrusted Source published in 2019 looked at whether CBD could improve sleep and or reduce anxiety. The study involved 72 subjects, with 47 experiencing anxiety and 25 experiencing poor sleep. The subjects were each given 25 milligrams (mg) of CBD in capsule form each day. In the first month, 79.2 percent of the patients reported lower anxiety levels and 66.7 percent reported better sleep.
Pain, which may also cause sleep problems, can be helped by CBD as well. A 2018 reviewTrusted Source in Frontiers in Pharmacology noted that there’s a fair amount of evidence to support the claim that CBD soothes pain. The authors note that by reducing chronic pain, CBD can improve sleep.
Other research tells us that CBD affects the sleep cycle. Research from 2014Trusted Source looked at four patients with Parkinson’s disease. It found that CBD improved the symptoms of REM sleep behavior disorder (RBD), a disorder in which a person acts out their dreams. RBD is associated with poor sleep and nightmares.
A 2017 review also noted that CBD may be helpful in treating RBD, and that it shows potential for treating excessive daytime sleepiness.
Grogginess, another symptom of insomnia, might also be affected by CBD. A 2014 reviewTrusted Source found that CBD could have the potential to promote wakefulness, based on both human and animal research. The authors noted they weren’t sure exactly how or why CBD promoted wakefulness in some instances.CBD may help treat:
Even studies that conclude that CBD can improve sleep aren’t always able to say whythis is the case. Most of the above-mentioned studies emphasize that we need more research on CBD before we fully understand how it affects our sleep.
However, as mentioned above, many researchers say that CBD improves sleep because it tackles the root causes of insomnia.
As more research is done on CBD, we’ll learn more about why and how it can help us sleep.
There are a number of ways to take CBD. It comes in a few different forms, including:
Generally, vaping CBD gets it into your system faster than other forms. However, there’s not much research on vaping CBD, and vaping in general may pose respiratory risks.
The dosage of CBD you use, and the time you take it, will depend on a number of factors. Your weight, personal body chemistry, and the nature of your sleeping troubles will affect how the CBD works. What works for some people might not work for others.
Most clinical trials on CBD and sleep have involved giving the subjects anywhere between 25 mg to 1,500 mg of CBD per day. It’s best to start with a low dosage and gradually increase it until you find something that works for you.
Much of the research on CBD, anxiety, and sleep has noted that many patients don’t notice an immediate difference. The 2019 study mentioned above noted that it took about a month for the subjects to notice a difference. Be patient, and remember that you’re unlikely to get immediate results.
