Narrative:

On climb out with first officer flying at approximately 17;000 ft; we received ECAM; air engine 1 bleed fault. ECAM procedures followed immediately. After completion of ECAM procedures and as follow up with FM was started; both pilots noticed an increase in heat in the cockpit and hypoxia type symptoms. Both pilots' donned oxygen masks; emergency declared; descent initiated; and return to [departure airport]. I looked at pressurization initially when ECAM occurred and I did not notice any abnormalities with pressure. The only abnormal indication was an elevated (300 C) temperature and amber warning on engine 1 bleed air. All valves in system reacted as expected and no further incidents reported. Neither flight attendants nor passengers reported any symptoms. Overweight landing procedure followed. After completion of flight; both pilots still felt physiological symptoms and both visited a medical facility; I was cleared to return to flight status with no restrictions.
