Sleep is a special time when your body and brain rest and recharge. Even though you look still and quiet, a lot is happening inside you.
💤 What Happens to Your Body?
-
Muscles relax. Your body becomes still so you don’t act out your dreams.
-
Breathing and heartbeat slow down. This saves energy and calms you.
-
Temperature drops a little.
-
Cells repair themselves. Your body fixes damage and grows new cells.
-
Immune system gets stronger. This helps fight sickness.
🧠 What Happens to Your Brain?
Sleep has different stages that repeat in cycles during the night:
🌙 Stage 1 (Light Sleep)
-
You start drifting off.
-
You can wake up easily.
-
Muscles may twitch.
🌙 Stage 2 (Deeper Sleep)
-
Your brain waves slow down.
-
You are harder to wake.
-
Memory and learning begin to process.
🌙 Stage 3 (Deep Sleep)
-
This is the most restful sleep.
-
The body heals itself.
-
Growth hormone is released.
-
You feel refreshed when you get enough deep sleep.
🌙 REM Sleep (Dream Sleep)
-
REM stands for Rapid Eye Movement.
-
Your eyes move quickly under closed lids.
-
The brain becomes very active, almost like when you are awake.
-
This is when you dream the most.
-
Memories and emotions get sorted and stored.
Every night, you cycle through these stages about 4 to 6 times.
- In short:
During sleep, your body rests, repairs, and refuels. Your brain organizes memories and processes thoughts, while you drift through cycles of light sleep, deep sleep, and dreaming.
