The Effect of Cigarette Smoke on Sleep Quality and Physical Activity in People With Multiple Sclerosis

Plain-language summary

Current evidence suggests that cigarette smoke increases disease progression in people with multiple sclerosis (PwMS) and worsen their symptoms. 70% of PwMS report sleep disturbances that negatively affects their quality of life. Cigarette smoke has been found to be associated with sleep disturbances in healthy adult smokers, but this relationship is unknown in PwMS. Also, those who smoke cigarettes have less physical endurance resulting in undesirable effects on physical activity. Also, current evidence suggests that genes play a major role in smoking behavior and that certain genetic differences greatly affects nicotine dependence. To our knowledge, this was never explored before among PwMS. This study aims to explore the association between cigarette smoke, sleep quality, and physical activity in PwMS. Another aim is to explore the genetic susceptibility of people with MS to cigarette smoke, specifically to nicotine dependence
