Summary
This study looked at how lack of sleep and evening light exposure stop morning bright light from helping teens reset their internal body clocks. Researchers tested 88 adolescents aged 14-17 to find the point where morning light stops working. The goal is to understand these limits so better sleep and light strategies can be developed for teens.
