Cannabidiol — also known as CBD — is one of the main cannabinoids in the cannabis plant. Cannabinoids interact with your endocannabinoid system, which helps your body maintain a state of balance and stability, or homeostasis.
Unlike tetrahydrocannabinol (THC), CBD isn’t psychoactive, meaning it won’t get you “high.” Instead, it has a range of health applications, like reducing seizures in people with epilepsy and pain relief from various conditions.
Some research and anecdotal evidence suggest that CBD can also help you get a good night’s sleep. Here’s what you need to know about using CBD for sleep.
To understand whether CBD can improve sleep, we first have to understand what causes poor sleep.
- 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 painandrestless 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.
While research on CBD is still in its infancy, some research suggests that CBD can treat anxiety.
Pain, which may also cause sleep problems, can be helped by CBD as well. A
Other research tells us that CBD affects the sleep cycle.
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
CBD may help treat:
- the causes of sleepiness
- excessive daytime sleepiness
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.
Side effects are relatively uncommon. However, you may experience some minor side effects.
Possible side effects
- changes in appetite
- changes in weight
Though CBD is generally regarded as safe, a 2019 study done on mice did raise concerns about CBD’s potential for liver damage. CBD may also interact with other medications you’re taking, so speak to your doctor before using it.
Currently, the Food and Drug Administration (FDA) doesn’t guarantee the safety, effectiveness, or quality of over-the-counter (OTC) CBD products. However, in order to protect public health, they can take action
Since the FDA doesn’t regulate CBD products in the same way they regulate drugs or dietary supplements, companies sometimes mislabel or misrepresent their products. That means it’s especially important to do your own research and find a quality product.
Before you buy CBD from a company, research their history. Avoid companies with a history of mislabeling CBD, and opt for CBD that has been tested by a third party.
According to the Mayo Clinic, doctors seldom recommend using sleep medication for longer than a few weeks. While CBD and other medication can be helpful, it’s important to get to the root cause of your sleep problems.
You may need a physical examination, to change your sleep habits, or to change your medication. Talk to your doctor if you have trouble sleeping.
It’s essential to talk to your doctor before taking supplements or medication of any kind — including CBD. A doctor is best equipped to tell you how to use CBD to improve your sleep based on your specific circumstances.
Is CBD Legal? Hemp-derived CBD products (with less than 0.3 percent THC) are legal on the federal level, but are still illegal under some state laws. Marijuana-derived CBD products are illegal on the federal level, but are legal under some state laws. Check your state’s laws and those of anywhere you travel. Keep in mind that nonprescription CBD products are not FDA-approved, and may be inaccurately labeled.
