We all get afraid and feel fear. Seeing a spider, a loud noise or a creak on floorboard late at night can strike fear suddenly right through our bodies. The feeling of fear can make your heart race, breath quicken, scream, sweat pupils dilate, freeze you in place and can even cause involuntary urination. These are all stress reactions caused by our limbic system a chain reaction in areas of the brain that work together to control a built-in ‘fight-or-flight’ response. We have this built into us to help us react to and survive threats. If not for fear, we would most likely not have survived as a species. Lots of people actually seek out fear enjoying being and feeling scared. Watching horror films, playing scary games or even going on a roller-coaster. When our ‘fight or flight’ response is triggered, we release chemicals which are similar to that of when we are excited or happy. When we trigger this in what we perceive as a safe environment, it is thought that we can then enjoy being scared and the chemicals running around our body that are akin to high arousal states.
