Not later, but longer: sleep, chronotype and light exposure in adolescents with remitted depression compared to healthy controls

Adolescents with remitted depression slept significantly longer on work-free days compared to healthy controls.

• No significant differences in chronotype or social jetlag were found between adolescents with remitted depression and healthy controls.
• Adolescents with remitted depression reported worse subjective sleep quality than their healthy counterparts.
• Light exposure was higher in remitted patients, but this was influenced by living in a rural environment.
• The potential for chronotype modification during remission suggests a need for further investigation in longitudinal studies.
