About CBD for Sleep
Since it became legal to use CBD for Sleep in the United States, people have been using this natural remedy to help them sleep better at night. Several studies support that CBD might improve sleep, although it’s important to keep in mind that it might not be effective for everyone.
In a case series at a psychiatric clinic, researchers documented monthly anxiety and sleep scores in 103 adult patients who received CBD to treat a primary diagnosis of either anxiety or poor sleep. Patients were treated with CBD for 3 months and comorbid psychiatric disorders were not excluded.

Most patients reported improved anxiety and sleep, and these improvements were sustained over the study period. The researchers found that in the first month of CBD treatment, 79.2% of patients with an anxiety diagnosis and 66.7% of those with a sleep disorder experienced an improvement in their symptoms. In the second month of treatment, these percentages rose slightly to 78.9% and 69.4%, respectively.
The researchers found that CBD may boost the levels of a molecule in the body called anandamide, which is known to promote sleep. Additionally, CBD may interact with the CB1 receptors in the brain, spine and gut that regulate pain transmission, anxiety, inflammation and circadian rhythm.
However, the research also shows that it takes time for CBD to work. In Shannon’s study, people whose main complaint was insomnia saw their symptoms improve in the first month of treatment, but the improvements faded in months two and three. Similarly, in animal experiments, CBD increased NonREM sleep but did not affect Intermediate or REM sleep and did not alter the number of sleep stage transitions.
