You have a few options. If you are unsure about what to do give it to a professional guitar tech or better still (if you are coming to Samois this year) give the guitar and adjuster tool to the Dupont guys on the stand!!
If you fancy having a go yourself firstly check the rod still has the nut on it that you will be tightening. I say this because if it is loose it may have vibrated off. Assuming it is just loose take up any slack by tightening clockwise - do this with the strings on. As you feel any resistance stop and check. If you need more tension to correct relief beyond 10 thou of an inch go very slowly no more than half a turn without checking.
DO NOT FORCE ANYTHING. If it becomes hard work or force is required STOP. It is at this point rods snap or things get damaged.
Under normal circumstances it is OK for a player to fine tune an instrument. Things move due to different string choices, weather, etc. I also put more relief in the neck if I am doing a rhythm gig - as the string clearance makes for a cleaner, louder guitar. If I am soloing I prefer a straighter neck - and tightening also drops the action overall making the guitar generally easier to play.
A rattling rod in your neck!!?? If nothing else an adjustment will make the guitar sound better.
