Endorphins are like little helpers in our body that make us feel happy and good. They are chemicals that our brain releases when we do things that make us feel good, like playing or laughing. It's like when we get a hug from our parents or win a game of tag with our friends. Endorphins are like a special treat that our body gives us to make us feel even better. They can help us feel less pain and more positive. It's like a little pat on the back from our brains that says "good job, you're doing great!" So remember, endorphins are our special helpers that make us happy when we do things we love.
