DARIEN, IL \u2013<\/strong> A new study to be presented at the SLEEP 2025 annual meeting found that adolescents who prefer to sleep and wake up later (\u201cnight owls\u201d) reported greater impulsivity than those who prefer to sleep and wake up earlier (\u201cmorning larks\u201d).<\/p>\n

Results show that adolescents with self-reported evening preference, or \u201cnight owl\u201d tendencies, reported greater negative urgency and lack of perseverance, which are two aspects of impulsivity. This means that they were more likely to act impulsively when experiencing negative emotions and quit difficult tasks. In contrast, there was no association between objectively measured circadian phase and impulsivity.<\/p>\n

\u201cSurprisingly, we did not find a significant link between dim light melatonin onset and impulsivity in our sample,\u201d said lead author Riya Mirchandaney, who is a doctoral candidate in clinical-health psychology at the University of Pittsburgh. \u201cThis suggests that there may be unmeasured psychological or behavioral factors influencing both impulsivity and the self-assessment of circadian preference, regardless of the timing of an individual\u2019s internal circadian clock.\u201d<\/p>\n

According to the American Academy of Sleep Medicine, circadian rhythms are internal biological rhythms that exist in all living organisms. This timekeeping system, or \u201cbody clock,\u201d is synchronized to the 24-hour, light\u2013dark cycle. Circadian preference reflects an individual\u2019s desired timing of sleep and wake, and circadian timing can be objectively measured by analyzing saliva or blood plasma to detect dim light melatonin onset.<\/p>\n

The study involved 210 adolescents across two studies. They had a mean age of 17 years, and 60.5 percent were female. Participants completed self-reported measures of impulsivity and circadian preference. Laboratory samples of saliva were taken to assess circadian phase by determining dim light melatonin onset. During a week-long protocol, participants also wore a wrist actigraph to estimate sleep midpoint and duration, and at bedtime they completed an assessment of impulsivity.<\/p>\n

Mirchandaney emphasized that the results could influence future research to help teens avoid the negative effects of impulsivity, which is a well-established contributor to alcohol and substance use.<\/p>\n

\u201cAdolescence may be a prime opportunity for preventing adverse outcomes associated with impulsivity using chronotherapeutic interventions to advance sleep and circadian timing,\u201d she said.<\/p>\n

This study was supported by grants from the National Institute on Drug Abuse and the National Institute on Alcohol Abuse and Alcoholism within the National Institutes of Health. The research abstract was published recently in an online supplement<\/a> of the journal Sleep and will be presented June 9 during SLEEP 2025 in Seattle. SLEEP is the annual meeting of the Associated Professional Sleep Societies, a joint venture of the American Academy of Sleep Medicine and the Sleep Research Society.<\/p>\n
