Young people who go to bed later drink and smoke more due to their impulsivity
Young people who prefer to stay up late are more impulsive than their peers who go to bed earlier, which makes them more likely to drink alcohol and smoke, a new study in the journal Chronobiology International, reports.
In the first study of its kind, researchers from the University of Surrey and Brunel University London investigated how being an evening type (someone who prefers to stay up late and functions better in the evening) links to impulsivity, anxiety, and substance use. Young people often prefer to stay up late, and those who do are known to be at higher risk of mental health issues and problematic substance use.
To better understand why this is, researchers recruited 191 participants aged between 18-25 years old. Participants were surveyed on their sleeping preference (morning or evening types), their sleep quality, levels of anxiety and impulsivity, and asked about how many cigarettes they smoked and how much alcohol, coffee, and other caffeinated drinks they consumed.
