As Sharon says, the flight or fight response is wired in us but it needs to translate into acceptance or you'll become a hostage to your own fear.
The first step to manage anxiety in uncertain times is to assess your immediate situation.
"Ask, is red alert really called for right now?" says Sharon.
"I'm in my home. I'm safe. I've sanitised my hands. I'm not letting people into my home unless they're family or they live with me. There's no physical danger in this moment.
"So to stay at red alert or DEFCON 5 can be unhealthy. It can weaken the heart, it increases blood pressure and it can lessen longevity."
The second step to flip "from lizard brain to cognition" is to stop feeling as if your reaction is reality.
That means getting proactive. Organise your work space. Do a great project with the kids. Anything that gives you focus and a recalibration about your situation.
