I’m sure you think you know a lot about adrenaline. It’s the ‘Let’s do this’ hormone which makes you feel excited and confident when you’re about to bet on a risky hand of cards or rushing past a red traffic light. A racing heart, sweaty palms and more rapid breathing are classic accompaniments to the ‘adrenaline rush’ accompanying a flight-or-fight response.
At a physical level, adrenaline makes blood vessels contract and redirect blood towards major muscle groups including the heart and lungs. For a limited amount of time, you become stronger, faster and more perceptive.
On the other hand, if adrenaline peaks too often, the body is going to tire like a burned-out motor. The burst of energy accompanying an adrenaline high zaps your body’s glucose, meaning you’ll feel the need to refuel after watching a tense boxing match or playing a tough round of golf. Super high levels of the hormone due to stress in everyday life can cause heart damage, insomnia and anxiety. Watching your stress levels, as ever, is essential to a happy body and mind.
