This is an ancient response that human beings developed to help them respond to danger (or threat of danger). It happens in less than a second without us having to consciously think about it. This reaction helps prepare our bodies to fight or to run away (flight).
When we detect a ‘threat’ in our environment (sometimes without realising), a hormone called adrenaline is released into our bodies. This makes our heart beat faster to pump oxygen-rich blood to our arms and legs to help us fight or run away. Our muscles tense (ready for action), and we sweat and flush to keep our bodies cool. We might get a funny feeling (butterflies) in our tummy because our digestive system is not our top priority. Some people might feel dizzy too. Sometimes we ‘freeze’ because it is sometimes safer to ‘play dead’ than to fight or run away.
If we do have to fight or run this reaction is very useful, but these days most of the ‘threats’ we have are social and emotional, not life threatening. This means that the energy we create is not used up and sometimes continues for longer. We can also start to shake, or develop aches and pains, as our muscles are ready to do something that they do not need to do.
Sometimes these physical reactions are frightening or worrying if we don’t know what is causing them. This makes more adrenaline.
This reaction is not a bad thing. It is one of the things that helped the human race survive. It only causes problems if:
- it is ‘switched on’ by things that are not normally a threat or danger
- our response is too big when we only need a small one
- we have trouble switching it off again
