Is it easier to cool humid or dry air?

The same way that high humidity makes the heat feel hotter, dry air makes the cold feel colder.

High humidity levels slow down the heat release, trapping more heat and making the body feel hotter.

Does humidity affect oxygen levels?

The amount of humidity in the air (water content) on the oxygen concentration. As water content increases, this reduces the oxygen content (called partial pressure) of oxygen in the air. Thus it would make sense that during humid conditions, less oxygen is available in the air.
