Can CBD Help You Sleep?
A small but growing body of scientific research provides some support for CBD as a sleep aid. A study out this month, for example, suggests CBD might help people with short-term sleep problems.
And Joseph Maroon, M.D., a clinical professor and neurosurgeon at the University of Pittsburgh Medical Center who has researched the effect of cannabis on the brain, says that CBD has properties that could help some people sleep better. Most notably, he says, it appears to ease anxiety and pain, both of which can make it harder to fall asleep or stay asleep.
One way CBD may help with sleep is by easing anxiety. In a study in the January issue of The Permanente Journal, published by the Kaiser-Permanente health insurance company, Colorado researchers looked at the health records of 72 patients who were treated with CBD for either anxiety or poor sleep.
During the three-month study, anxiety levels did decline, even in people whose main complaint was poor sleep. For those with sleep problems, the results weren’t as clear cut, though people did report some improvement in the first month.
CBD may work better for anxiety than sleep. There’s more evidence for CBD’s ability to ease your anxiety than to help you fall asleep, though helping you relax could help you sleep, too.
Short-term use might be best. CBD’s ability to improve sleep may diminish the longer you use it, so you may not want to use it daily or long-term.
Higher doses could work better. There’s not much research on dosing, but what there is suggests low doses might not be very effective. A 2004 study found that low doses (15 mg in this case) didn’t help people fall asleep and might actually have made people more wakeful. And an even earlier study found that a relatively large dose—160 mg—worked better than a lower one. In Shannon’s study, patients were given a 25 mg dose.
