Body clock patterns and risk of substance use problems in teenagers

Circadian Biology Weekly Brief ↗PubMed ↗DOI ↗

Updated

Abstract

Adolescents with drug and alcohol problems are reported to have sleep problems.

  • A shift to later preferred sleep times during adolescence can lead to sleep loss.
  • Early school start times may exacerbate sleep loss and circadian misalignment.
  • Sleep loss and circadian misalignment are associated with disruptions in reward-related brain function.
  • Impairments in inhibitory control may be linked to deficits in mature reward functions.
  • Changes in sleep and circadian rhythms during adolescence could accelerate substance use and related issues.
