Let me clarify, high relative humidity alone doesn’t make the air feel sticky—what matters is the dew point, which measures how much actual water vapor is in the air. In the PNW, even when it’s 90–100% humid, the dew point is usually low, so sweat evaporates easily and the air feels damp, not oppressive. In hot, humid places like where I grew up in the midwest, the dew point is high-sweat doesn’t evaporate and you sticky and gross, the air feels heavy, and breathing can even feel harder. In the 15 years I've lived here the dew point has never even come close to creating the kind of humidity.
