What will happen if you don't sleep for many days

Missing sleep isn’t just about feeling tired — it rewires your brain, messes with your emotions, and slowly chips away at your mental health.

Memory gets fuzzy. Emotions get louder. Focus disappears. And over time, your brain starts reacting like it's in danger, even when you’re safe. Sleep isn’t a luxury — it’s maintenance for your mind, your mood, and your sense of self.

So if you’ve been running on fumes, there’s a reason everything feels harder. Your brain’s not broken — it’s just begging for rest.
