When the relative humidity of the air is high, your sweat will evaporate leaving you to feel sticky and wet.

VERY SLOWLY.

Explanation:

When he air we breathe is readily saturated with water, the sweat on your skin can't evaporate. This state of the body will leave you feeling sticky and warm, in as much as the body tries to cool down. High humidity in hot weather will only worsen your discomfort, as the moisture simply sits on your skin unable to evaporate.

In the effort to cool, our bodies must work even harder. This leaves our body to excessive sweating, depth of blood circulation, increased rate and also increased respiration.
