Are you a quick healer?
stay out of the hot room for at least a week. When you go back, take it easy on that area for at least another week. for example, if the tattoo is on your arm, don’t stretch that arm like you usually do in ardha chandrasana, just lift it up slightly. if there are bright colors, you really don’t want your sweat making them fade while it’s healing.
you spent a lot of money on that new tattoo, don’t mess it up by stretching the skin while it’s healing!
