We all know someone, or perhaps you are that person yourself, that loves a bit of adventure, whether that is the thrill of speeding around a rollercoaster or jumping out of a plane or perhaps even taking part in a Tank Driving Experience like those you can find at www.armourgeddon.co.uk/tank-driving-experience Regardless of what activity it is that gets your blood pumping there is one common thread between everyone that seeks this – Adrenaline!
Our bodies need adrenaline in order to survive and it plays an important part in the fight, flight or freeze mechanism that we have within it. For some, this mechanism is triggered too easily and can lead to high levels of anxiety and panic attacks. Essentially adrenaline is a chemical that is released from the adrenal glands during moments of high stress or excitement. It causes a number of changes to occur within our bodies, some functions are reduced, others supressed and some heightened.
The functions that are supressed include digestion, blood flow, and pain sensitivity. Blood flow is directed to the internal organs that need it the most including the lungs and heart this is in order to be able to either fight or flight. The reason digestion is supressed is to help conserve energy once again to ensure that you can perform whatever task is needed and almost seem super-human for a short period of time.
Heightened functions include creating an almost superhero style quality to the body and is a bit like jump-starting a car. After the release for adrenaline blood pressure spikes, breathing is increased, and a surge of sugars are released into the bloodstream. Some people also report feeling like they are invincible and can do anything. The release of sugars gives the body an energy shot which allows you to jump out of that plane or run away from the tiger that is chasing you. Equally the increase in respiration helps to provide the muscles with more oxygen so they can operate at a heightened level. It is these heightened feelings that give some people the euphoric feeling when they speed around the rollercoaster. These “highs” can last a while after the event and can almost become addictive in some way which is why you find some people seeking new thrills.
There is, however, an after effect of an adrenaline surge and this is what causes issues for people who experience them on a regular basis perhaps as a result of heightened anxiety levels, periods of high stress or other trauma-related issues such as Post-Traumatic Stress Disorder. This ‘let-down’ effect can include the involuntarily shaking of the arm and leg muscles.
