Why do we get sleepy?

Quick Answer

We get sleepy because our bodies have an inner clock and a ‘sleep pressure’ that builds during the day. When it’s dark and we’ve been awake for a while, the brain sends signals that it’s time to rest and recharge.

Story Synopsis

Sometimes sleepiness feels like a soft wave: heavy eyelids, slower thoughts, and a wish to curl up. This story explains why that happens. Miluna introduces two gentle helpers. One is your inner clock, which notices day and night. When it gets darker, your brain begins to prepare for rest. The second helper is ‘sleep pressure.’ As you stay awake, your body uses energy and your brain does lots of work. Little by little, the desire for sleep grows—like a quiet reminder. The story also mentions that calm routines—dim lights, cozy blankets, and a story—can help the body understand it’s safe to rest. It keeps everything warm and comforting, showing children that sleepiness is a kind signal: your body is getting ready to recharge.
