Detaljerad beskrivning
Rationale The stress response is a biological cascade of physiological, psychological and behavioural processes allowing individuals to detect, interpret and react to perceived or actual threat. In the modern world, sleep loss is increasingly common, can be caused by stress, and can exaggerate the stress response in otherwise healthy individuals. Previous research using sleep restriction approaches has demonstrated that a loss of sleep reliably increases physical and psychological feelings of stress. The endocannabinoid system (ECS) is a network of receptors that regulates both the stress response and sleep processes, making it a suitable target to allow the study of these processes. Cannabinoids are compounds naturally occurring in the Cannabis plant that act on the ECS.
Approach This study will investigate the effects of different cannabinoid oils on physiological and psychological measures of stress following sleep restriction.
Participants will be healthy adults between the ages of 18-60 who are currently experiencing higher than average stress. Participants will undergo a previously validated sleep restriction paradigm (sleeping for 4 hours only) prior to the experimental session. This will allow the research team to safely replicate heightened stress related to poor sleep. Participants will be enrolled in the study for a minimum of 2 days and a maximum of 9 days.
