In what ways is it bad to paint your nails all the time?

I love painting my nails, my friend says im addicted. I tend to paint them every three days to every other day at the most. I have have been wondering can that be bad in any way. Like I'm usually right over nails when i do them, the door is usually shut, and my ceiling fan is on a low speed. So if there is anything that you may know PLEASE tell me.
