Aversion therapy

Aversion therapy is like when you don't like something and you try to change your feelings about it by doing something that makes you feel really uncomfortable.

For example, let's say you love eating chocolate but your parents think you eat too much of it, so they might take you to a doctor who uses aversion therapy to help you stop eating so much chocolate.

The doctor might have you eat a really gross food, like Brussels sprouts, and then make you smell chocolate. This is really uncomfortable because you don't like the gross food, but you do like the smell of chocolate. The doctor does this a few times to train your brain to associate chocolate with feeling gross instead of feeling happy.

Over time, you might start to not like chocolate as much because your brain has been trained to feel like it's a gross food. This is how aversion therapy works - it tries to change how you feel about something by making you associate it with something negative.
