Why Do We Have a 'Fight or Flight' Response?

Imagine you're in the forest and a bear is chasing you. Your body suddenly feels like it has superpowers, your heart beats fast, you can run faster, and you feel stronger. This is called the 'fight or flight' response. It’s our body's way of helping us survive dangerous situations by preparing us to either fight the danger or run from it.

What happens in our body? When we feel threatened, our brain sends a signal to our adrenal glands, which then release hormones like adrenaline into our bloodstream. This makes our heart beat faster and gives us more energy, so we can react quickly.
