My Husband Has Always Had Issues With Sleeping To Long.

My husband has always had issues with sleeping to long. Over the past 3 years it has gotten progressively worse. He will go to bed at midnight and wake up between 1:30-3. The last few days he has been getting up at 8 to watch over the men installing our new air conditioner. Last night he went to bed at 10 got up at 9 and tonight he went to bed at 8. Well the last couple of days he hasn't felt good. Could the sleeping have something to do with that?
