How Tattoos Might Affect Your Workout
Guest posted a topic in TopicsTattoos may permanently alter the physiology of skin in ways that affect sweating. According to a small, new study, the amount and saltiness of sweat change after skin has been dyed, a finding that might have implications for athletes who ink large swaths of their bodies and maybe even for those of us who sport one or two discreet tattoos (such as the small one on my right shoulder, in case you were wondering). Tattoos are decorative, often metaphoric, sometimes regrettable, but always injurious. To create a tattoo, the artist punctures the skin with dye-filled needles at a rate of up to 3,000 times per minute. The dye is injected into the skin’s dermal layer, which is also where most sweat glands are. The body recognizes these injections as abnormal. They have slightly damaged the tissue and left behind a foreign substance, the ink. So the immune system gears up, sending a variety of cells to the site of the inking. Some cells carry off tiny amounts of the ink, primarily to the lymph nodes, where it dissipates. Other immune cells merge with the remaining ink, so that both become long-term residents of that portion of the skin. Still other cells initiate an inflammatory response, helping the injured tissue to mend, which it usually does within a few weeks.
