Cardiovascular Effects of Anxiety

Activity in the sympathetic nervous system increases our heartbeat rate, speeds up the blood flow throughout the body, ensures all areas are well supplied with oxygen and that waste products are removed. This happens in order to prime the body for action.

A fascinating feature of the “fight or flight” mechanism is that blood (which is channeled from areas where it is currently not needed by a tightening of the blood vessels) is brought to areas where it is urgently needed. For example, should there be a physical attack, blood drains from the skin, fingers, and toes so that less blood is lost, and is moved to “active areas” such as the thighs and biceps to help the body prepare for action.

This is why many feel numbness and tingling during a panic attack-often misinterpreted as some serious health risk-such as the precursor to a heart attack. Interestingly, most people who suffer from anxiety often feel they have heart problems. If you are really worried that such is the case with your situation, visit your doctor and have it checked out. At least then you can put your mind at rest.
