Adrenaline, medically known as epinephrine, is released into the bloodstream from the medulla in the adrenal glands when surfers ride intense waves. So, is it good or bad to be an adrenaline junkie?
Adrenaline is a fantastic hormone. As danger and fear are activated in human's brain, adrenaline bursts invade almost all body tissues and change the way muscles behave.
When surfers put their life in danger - especially in big wave surfing conditions or dangerous wave peaks - their bodies ignite the so called fight-or-flight response, a reaction to the information transmitted to the nervous system by your senses.
