Even though CBD is known to induce alertness, in other cases and studies, it was revealed to be an effective sleep regulator. This effect, seemingly contradictory, reinforces the idea that the endocannabinoid system (ECS) acts as a regulatory system of balance, once that balance has been broken.
Researcher S. Shannon presented the case of a 10-year-old girl with post-traumatic stress disorder in which CBD was able to improve her quality of sleep, where other medications were not effective (Shannon, S. et al., 2016).
In a 4-case study on patients with Parkinson’s disease and associated sleep disorders, CBD regulated this disorder in 4 patients quickly and without any side effects (Chagas, MH et al., 2014).
It has also been proven that some cannabis consumers who want to improve their sleep problems use varieties with a high content of CBD, particularly in those who have sleep disturbances associated with nightmares during a night’s rest (Belendiuk, KA et al., 2015).
It is interesting to see how, despite CBD not having any side effects when high doses were administered to healthy individuals, some patients said they felt drowsy at the very beginning of their treatment with CBD. This phenomenon is most likely explained by the anxiolytic effect of CBD that, when the patient’s level of anxiety is decreased, facilitates the predisposition of the body to rest and obtain a restful sleep.
