Everyone and anyone that has a tattoo will tell you one thing when you get your first, "be careful, they're addictive." The truth is, there are lots of studies out there that are totally right. You are likely to become addicted to getting that ink because of the adrenaline rush.
Before you know, you're half-sleeve turns into a full-sleeve. And your one-time matching sister tattoo turns into a best friend tattoo, a mom/daughter tattoo, and more. But regardless of how many you have on your skin, turns out that every time you take a seat at the tattoo parlour, you're actually boosting your immune system.
29 participants took part in a recent research study published in the American Journal of Human Biology. The study found that those with more "tattoo experience" (AKA people with more ink) adjusted to the ink process and reacted faster to immune system stressors.
So what does that mean for us? Well, the people in your life with a lot of tattoos might actually be able to fight off other things that hit their immune system.
"After the stress response, your body returns to an equilibrium," said Christopher Lynn an associate professor of anthropology at the University of Alabama to the Huffington Post. "However, if you continue to stress your body over and over again, instead of returning to the same set point, it adjusts its internal set points and moves higher."
So, if you just got that first tattoo and are 100% addicted and ready for more, this is just another reason to love and appreciate that badass body art.
