Why is it not safe to tan after a naval piercing?

You aren't supposed to tan indoors after getting a navel piercing because of the UV rays can dry out your piercing and make it uncomfortable, and if the lotion gets into your piercing it can get infected. Your piercing may take 6-12 months to heal so until then you should take good care of it and avoid tanning and swimming. You should wait until the weather cools down to get your piercing so then you have all winter for it to heal.
