A sleep study from Columbia University which surveyed more than 15,000 teens and found that “levels of depression and thoughts of suicide are higher in kids who have later bedtimes on school nights.” This provides powerful evidence that a lack of sleep not only affects teenagers physically but mentally as well.

The study found that “teenagers who went to bed midnight or later were 25% more likely to have signs of depression and 20% more likley to have thoughts of suicide.” Dr. Charles Bae, Cleveland Clinic stated that “In . . . adolescents . . . any amount of depression is serious and should be looked at and anything that could prevent it from happening . . . should be looked at seriously.”
