sleep CPU usage + threads

I have a daemon thread running that gathers info into structs, and then another regular thread that dumps the structs to file every 5 minutes. For the second thread i was just  doing something like this:

while(1){
     sleep(300);
   ..................


}

Just wondering if this will hog the CPU more than one would think.

Nope, a sleeping process/thread does not use any CPU.

sleep() is fine in a thread. It'll stop the whole thread from being scheduled until the time expires.
