Use sleep in the loop.

while <whatever>
     do 
      your command
      sleep 5
     done

while :; do id; sleep 5; done

It's a shell built-in that evaluates its arguments and exits with status 0. Sometimes incorrectly referred to as a no-op.

Actually, not needed here:

while sleep 5 ; do command ; done
