We asked many questions like, can tattoos can cause allergies? Or can they prime the immune system?
Alison Pearce Stevens from sciencenewsforstudents.org explains "research now indicates tattoos aren’t bad for everyone. In people who heal well, getting a tattoo may prime their germ-fighting immune systems for action — and in a good way."
She goes on to explain "When a tattoo is done right, that ink winds up in the dermis. This layer of skin lies beneath the epidermis, the outer layer that we see. The epidermis is always growing new skin cells and shedding old ones. If tattoo ink were placed there, it would last only about a month before disappearing"...
A study published in the American Journal of Human Biology uncovered that tattooing serves to inoculate the immune system. There are two reasons behind this. One is that they have less reduction in immunoglobulin A. The second is that getting a tattoo stimulates an immune response.
Immunoglobulin A is an antibody that helps the immune, gastrointestinal, and respiratory systems. Higher levels of the antibody help the body to ward of pathogens and even the common cold or flu.
chronicinktattoo.com write "In addition to immunoglobulin A, the above study also tested for cortisol levels. Cortisol is a stress hormone. It was tested in the study because cortisol is an immune response suppressant.
Multiple tattoos were found to reduce cortisol levels, improving the immune system benefits of tattoos, but also helping with stress reduction."
So maybe getting a tattoo could be good for you after all? As long as you use a reputable tattoo artist with experience and an ultra clean tattoo studio you will have body art to be proud of.
