So even though there are fewer particles in the air that could absorb heat from your body, there are still enough water particles to keep you cooler than normal. When the air humidity is very high, the perspiration process is impeded; it will be harder for water to be evaporated from our skin into the air since the air is already quite moist (full of water). This is because humidity causes your pores to open more than normal, which means that your skin produces more oil in response. With Temperature and Relative Humidity you can determine Dew Point of air, Preservation Index of paper, Days to Mold of wood, and finally, Equilibrium Moisture Content of wood, respectively.
