Among college students and athletes, insufficient sleep was linked to mental health issues, including self-harm and suicide ideation.
Results show that in adjusted models, insufficient sleep was associated with all mental health variables, and a dose-response relationship resulted when insufficient sleep was treated as categorical.
With every additional night of insufficient sleep, the risk of experiencing mental health symptoms increased on average by more than 20% – including an increased risk of 21% for depressed mood, 24% for hopelessness, 24% for anger, 25% for anxiety, 25% for desire to self-harm, 28% for functional problems, and 28% for suicide ideation.
