Dating back as far as 1500 B.C, historical texts indicate the use of cannabidiol for inducing sleep. Legalization has increased access to and research of CBD, with more scientists turning their attention to studying its medicinal effects.
To understand whether CBD can improve sleep, we first have to understand what causes poor sleep.
Many things can cause you to sleep badly. According to the Mayo Clinic insomnia can be caused by:
- mental health disorders,such as anxiety, post-traumatic stress disorder (PTSD), and depression
- medication, which can disturb your sleep-wake cycle
- physical conditions, such as chronic pain and restless leg syndrome
- caffeine, especially when consumed late in the day
- environmental factors, such as loud noises or an uncomfortable bed
If your insomnia is caused by external factors or related conditions, CBD may help by treating the causes of sleeplessness.
Research 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 review Trusted 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.
HOW CBD WORKS TO IMPROVE SLEEP
Even studies that conclude that CBD can improve sleep aren’t always able to say why this 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.
There are many ways to take CBD including vape oils, tinctures, capsules and gummies. Vaping CBD is becoming more popular, as research shows it gets into your system quicker therefore you can feel the benefits quicker.
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.
