Staying up late regularly can increase stress, cause mood swings, reduce concentration, and even lead to anxiety or depression over time. Your brain uses sleep to reset, repair, and regulate emotions. When you don’t get enough rest, it becomes harder to manage your mood, focus, and overall mental well-being. Aim for 7–9 hours of quality sleep each night. Try to maintain a consistent sleep schedule and avoid screens or caffeine before bedtime. Good sleep is one of the simplest ways to protect your mental health.
