We sleep because our bodies and brains need a complete system overhaul daily. It's for repair, memory consolidation, hormone regulation, and waste removal from the brain. If you don't sleep, your body literally breaks down. It's non-negotiable for survival and optimal functioning.

Simple reason hai – body ko reset karna hota hai. Poore din mein jo bhi wear and tear hota hai, usko repair karna. Brain ko saaf karna, memories organize karna. Without proper sleep, you can't function. It's not a luxury, it's a necessity. Don't compromise on it.

Amma always told us, 'Sleep is food for the soul and body.' It's when our body rests and heals. The doctor also explained it's for brain development and processing things. If we don't sleep well, we become tired and easily fall sick. So, it's very important to sleep peacefully.

We sleep because our bodies are essentially demanding a daily recharge. Otherwise, we'd probably just short-circuit or start yelling at inanimate objects. Plus, it's the only time my mind gets a break from thinking about taxes and bills. So, thank god for sleep, honestly.
