We've long been told to think twice before getting a tattoo, because you don't want to end up regretting the ink.
But now we've got another reason to be 100% sure we REALLY want one before going under the needle.
It turns out tattoos have a strange side-effect on our body: it changes the way we sweat.
Scientists at Alma College in Michigan have found that people with tattooed skin produce less sweat than those with non-tattooed skin.
The results have lead medical professionals to warn people about the risks of getting a tattoo, as sweating is a vital function that helps us to control our body temperatures.
A reduction in the amount we sweat can potentially cause us to overheat or suffer heat stroke.
Furthermore, the sweat of those with tattoos contained almost twice the amount of sodium, which can cause cramps and quicker dehydration.
