eli5 Why do we have pressure points?
In: 25
Pressure points are where larger nerves are able to be compressed. When you pinch a nerve, it temporarily stops the signal from travelling along the nerve – like putting a kink in a hose to stop the flow of water.
So the message is never delivered. Why is this important? Because this explains why when we pinch a nerve, we often feel numbness or tingling distal (farther away from) to the point that is affected.
Knots in muscles can often have this effect, which is why they can be so annoying – but of course someone targeting the nerve is also annoying too 🙂
