A recent study conducted by researchers from Macquarie University and the University of Sydney suggests that cannabinoid products may have an impact on the sleep patterns of adults with insomnia. The study, published in the Journal of Sleep Research, focused on the effects of a single oral dose of a cannabinoid product on sleep duration and quality.
The study involved 20 participants, all of whom had been clinically diagnosed with insomnia disorder. These individuals experienced difficulties falling asleep and staying asleep, which affected their daily functioning. The average age of the participants was around 46 years.
During the study, participants spent two nights at a lab, with one night involving a placebo and the other a single oral dose of a medical-grade cannabis oil containing THC and CBD. The order in which they received the treatments was randomized to ensure unbiased results.
After taking either the treatment or the placebo, participants were monitored using a high-density electroencephalogram (EEG) cap while they slept. The following morning, they underwent tests to assess their alertness and cognitive function. Surprisingly, the results showed a decrease in total sleep time and REM sleep following the cannabinoid treatment.
While the objective data indicated a decrease in sleep duration and REM sleep, participants themselves did not perceive a change in their sleep quality. Furthermore, their alertness and cognitive performance the next day remained consistent, despite feeling slightly sleepier after the treatment.
The study’s findings raise questions about the potential long-term effects of cannabinoid products on sleep patterns when used regularly. The researchers emphasized the need for further research with larger sample sizes and longer treatment durations to fully understand the impacts of medicinal cannabis on sleep and daytime functioning.
These results highlight a disparity between public perception and scientific evidence regarding the use of cannabis for sleep disorders. Despite the widespread belief in cannabis as a sleep aid, the research base is still limited, underscoring the importance of rigorous clinical trials to provide clear guidance for patients and healthcare providers.
As the field of sleep research continues to evolve, studies like this one play a crucial role in unraveling the complexities of how different interventions, such as cannabinoid products, affect sleep patterns and overall health. By expanding our understanding of these interactions, we can pave the way for more effective and evidence-based treatments for sleep disorders in the future.
