Sleep isn’t just rest — it’s repair. During sleep, your brain processes emotions, memories, and stress. When you don’t sleep enough, small problems start feeling overwhelming. A good night’s rest stabilizes mood, sharpens focus, and gives you emotional strength for the next day. Try keeping a bedtime routine: dim lights, no screens before bed, and gentle stretches or reading. Sleep isn’t a luxury; it’s one of the most powerful tools for mental well-being.
