Anxiety has the capacity to be both incredibly helpful and harmful. In the event of finding yourself face to face with a cougar, down to the wire on a final project, or gearing up for a big race, anxiety gives us the "juice" to dig deep, focus, and function at a high level. There are consequences of course to these bouts with anxiety, including adrenaline and its counterpart cortisol - which, studies have shown, can be very harmful in high doses. Similarly prolonged states of anxiety can lead to fatigue, GI issues, heart problems, and memory problems. For brief periods of time, this anxiety can be functional and help us overcome challenges.
