A study published in Journal of Adolescence that focused on young people aged 12-17 found that vaping nicotine (as well as dual smoking and vaping) is significantly associated with greater odds of reporting sleep problems such as sleeping restlessly, bad dreams, and daytime fatigue. Another study of high school students found that e-cigarette users were at increased odds of reporting insufficient sleep compared with cigarette smokers or people who had never used tobacco products.
Research points to a similar association in adults: in a study of people aged 18-65, those currently vaping nicotine were more likely to report less sleep compared with those who had never used e-cigarettes. Nicotine is known to increase heart rate, blood pressure, and glucose levels, all of which has the potential to delay or interfere with sleep.
