Can you wake a Beardie up with heat in brumation?

[MushuDaBeardie]

The title pretty much states it all. Not wanting to harm him at all. but I was wondering if more heat is added while he is asleep will the heat help him wake up and out of brumation. Just curious! His cage gets to about 67 degrees when he's brumating no lights. will he still in brumation for a long long long long time?? Thanks!

I leave my lights on a normal cycle and normal temperature range throughout brumation. They seem to react to some different signal than direct light or heat though. They just sort of come out of it when they're ready. I'm not sure how it's controlled exactly.
