Why anxiety shows up in your body first — the long answer, briefly, when nothing else has worked today
Racing heart, tight chest, churning stomach. Understanding the mechanism makes the symptoms less frightening.
Start here
Six things, in the order that makes the most difference. The first two do most of the work.
Nothing else has worked today. That is not a reason to skip this.
If you only do one thing from this page, do the first point below. It is first because it removes the most friction for the least effort.
What helps
The physical symptoms come from the same system that gets you out of the way of a car. It is fast, physical and not very smart.
Your heart rate rises, breathing speeds up and blood moves to your muscles. That is why your hands go cold and your chest feels tight.
Checking your body for symptoms increases your sensitivity to them. This is why health anxiety tends to escalate.
What to do when it does not work
The symptoms are uncomfortable but not dangerous. Chest tightness from anxiety does not damage the heart.
Because the system is physical, physical things work on it: slow exhales, cold water, walking, moving your shoulders.
The symptoms usually peak within ten minutes and then fall, even if nothing is done. Knowing that the peak is short helps more than it sounds.
Questions people ask
How do I know it is anxiety and not my heart?
That is a question for a doctor, and one worth asking once. After it has been checked, treating new sensations as anxiety is usually correct.
