Over the last few years there have been numerous studies looking at tattoos and their effect on the immune system.
And for all you fellow tattoo collectors I have good news. Tattoos do in fact have a positive impact on your immune system!
Are they going to keep COVID-19 away from you? Unfortunately, no, but people who have more than one tattoo generally have a stronger and healthier immune system than those who do not.
In one test, a group of 29 people were tested before and after visiting a tattoo shop in Alabama. The researchers tested levels of cortisol, which is one of the body’s indicators of stress levels, as well as Immunoglobin A, which is in simple terms is an antibody that helps our bodies fight infections . This study showed that those going in with no tattoos yet showed a greater strain on their immune system with a dip in their Immunoglobin A levels, while those going in for their second, third, or even tenth or more tattoo, actually experienced a large boost in their Immunoglobin A levels immediately following the tattoo. The full test can be read here “Tattoos to Toughen Up.”
Another test done in American Samoa by the same researcher took 25 saliva samples at the start and end of tattoo sessions on both tourists and locals getting tattooed. They also measured the tattoo recipients height, weight, and fat density to account for general health. Again, both cortisol and Immonoglobin A were extracted and tested, as well as an inflammatory marker C-reactive protein. A similar finding was concluded here, with Immonoglobin A staying remaining higher in the bloodstream even after tattoos had healed. As well, people with more and larger tattoos tested higher Immonoglobin A levels than those with less or no tattoos prior to the start of getting tattooed. This effect also appears to be dependent on getting multiple tattoos and not just having some time pass after getting tattooed once.
Of course having lots of tattoos won’t guarantee your health, but based on testing it can be beneficial for general immune health, and in particular skin injuries and health.
Both studies were done by Dr. Christopher Lynn.
