above 65 F (18 C)
to be uncomfortably high.

Can you have 100% humidity?

yes
, the condition is known as supersaturation. At any given temperature and air pressure, a specific maximum amount of water vapor in the air will produce a relative humidity (RH) of 100 percent.
Why does high humidity make me feel bad?
Humidity is how much water vapor is in the air. When we perspire, our bodies normally rely on air to get rid of the sweat that accumulates on the skin. This allows the body to cool down.
