My children first brought this to my attention: They told me they always felt really tired on our long trips and very sleepy. They told me it was due to lack of oxygen because I would always turn the A/C on "recirculate".
They might have a point here. The vehicles today are very good at sealing up wind noise and insulating the interior from heat or cold. So I guess it would follow that if the air conditioning system was recirculating all it's air, we would be re-breathing the same air.
So this time, on our long trip out and back from our vacation, I left it on outside air(or normal A/C setting), and they actually seemed to do better.
Something to ponder.
