Does cold air have less oxygen?
Increasing water vapour contributes to increasing air pressure, so in very warm air there's enough water vapor to make a room stuffy or humid. The two temperatures don't intrinsically have different amounts of oxygen—it's just that cold air is heavier and more dense, so it contains more oxygen by volume.
Is it harder to breathe in cold weather?
Even in healthy people, cold, dry air can irritate the airways and lungs. It causes the upper airways to narrow, which makes it a little harder to breathe.
