You've got a minor yet noticeable cut that just won't go away.
People keep asking you how you hurt yourself and you have to jog your memory to remember (Were you chopping carrots? Washing the vegetable peeler?). Studies have shown that psychological stress can affect the body's ability to heal itself
. People who showed higher than normal levels of stress took longer to heal from skin wounds, minor surgical procedures and even blisters. There's ample evidence that stress causes a release of chemicals (like cortisol and glucocorticoids) that get in the way of the healing process at numerous key steps and can also leave the wound more vulnerable to infection.
