Narrative:
On the descent into ZZZ at approximately 6000 feet; we both noticed a musty dirty sock; oily; overpowering smell. We both donned our oxygen masked with 100% oxygen. There was multiple power changes with the auto throttles during the descent. We landed and taxied to the gate and shut down the engines and opened both flight deck windows. We removed our oxygen masks and the smell was still overwhelming. We vacated the flight deck until the smell was gone. Both pilots experienced light-headedness; dizziness; irritated throats; headaches; and some nausea. Both pilots went to an emergency room for treatment.
