Why anxiety shows up in your body first — what works and what does not, when you feel restless rather than tired
Racing heart, tight chest, churning stomach. Understanding the mechanism makes the symptoms less frightening.
Start here
Here is what tends to work, in the order that helps most.
Restless is different from tired, and it needs a different approach.
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.
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.
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
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.
Because the system is physical, physical things work on it: slow exhales, cold water, walking, moving your shoulders.
The symptoms are uncomfortable but not dangerous. Chest tightness from anxiety does not damage the heart.
