Can I harm my Macbook Pro if I prevent from sleeping for an extended period?

I'm at currently at a location where my wireless connection is iffy and often gets dropped, after which it's frequently a struggle to get it back. I've discovered that this is much less likely to happen if I never close the laptop or otherwise put it to sleep (or shut it down). In order to maintain the connection, I've set it to dim after 15 minutes but not to sleep automatically when plugged in (screen shot below). However, I'm worried that I could harm the Macbook if it doesn't sleep for several weeks straight. Is there any reason to worry? Thanks for any information.
