Sleep Quality
Supporting Mental and Physical Well-Being - Why Sleep Matters

​Sleep is essential for emotional regulation, cognitive functioning, physical health, and overall well-being (Walker, 2017). Adequate sleep helps children and teens manage stress, stay focused, and develop resilience. Conversely, poor sleep can worsen mental health issues, increase irritability, and impair learning.

An important note for teens and sleep, during adolescence, the body's natural sleep-wake cycle shifts. Starting around ages 10 to 12 and continuing into the mid to late 20s, the brain releases melatonin, a hormone that makes us sleepy, about one hour later each year (J. DeCarli, CBI Programs). This shift makes it harder for teens to fall asleep early, especially when early school start times require them to wake up before they’re naturally prepared to sleep, leading to sleep deprivation and daytime fatigue.
