I was about to comment on why, but people here have described it all perfectly. If you want some pictures to explain it further or easier, google: sympathetic vs parasympathetic nervous system. There are great comparisons on google images and you will see and recognize the physical aspect of it all very easily. Hormones have very powerful effects on the human body. When you’re on a roller coaster for example you kind of “force” your body to release the hormones that make you enter “fight or flight”, the sympathetic nervous system. It’s very physical, even though you think it’s your brain playing tricks on you.
