Anxiety is a presence of unwanted energy – so people when they may have sweaty hands, they may get
quite shaky, they may feel dizzy, their breathing will increase, the rate of
their breathing and it’s an incredibly aversive experience. And it’s because
there’s adrenaline in our system, so anxiety is actually a very helpful
emotion to have. Years and years ago, if you think about cavemen, if they see a
big tiger hurtling towards them their body fills with adrenaline and they have
the fight-or-flight response. So their body’s full of adrenaline, their heart’s
beating really fast and that’s pumping blood to all the vital organs – like their
leg muscles so they can run away, their chest and arms so that they could fight
the tiger, because they’re preparing to either flee or or fight to save their
life. What’s unhelpful about that now is if your doctor causes you anxiety – going to
the hospital – you can’t fight them or run away, so the adrenaline comes into your
body but then it sits there with no release because you’re not able to have
a burst of activity that releases it. So all that adrenaline is sitting in your
body and it’s making you go a bit shaky, a bit
sweaty your heart’s pounding but it’s no real reason. And that’s where
anxiety becomes a problem for people.
