Why Sleep Matters for Mental Health

This lesson explains why sleep is a core factor in mental health, not just a recovery period for the body. Students will learn how sleep affects mood, attention, stress regulation, memory, and emotional control, and why even small sleep problems can make mental health symptoms harder to manage.

The lesson also distinguishes normal sleep loss from chronic sleep disruption and shows how poor sleep can both worsen existing mental health concerns and increase vulnerability to new ones. Later lessons will go deeper into sleep science, common sleep problems, and practical strategies for improving sleep.
