  • Interesting fact: During the heating months of winter, the relative humidity of the average American home is 13% nearly twice as dry as the Sahara Desert.
    • Humidity Moisture; dampness; a moderate degree of wetness, which is perceptible to the eye or touch; -- used especially of the atmosphere, or of anything which has absorbed moisture from the atmosphere, as clothing.
    • Humidity The content of water vapor in the air, expressed as a percent of the maximum amount of water vapor that the air can hold at the given temperature; also called relative humidity. The capacity of the air to hold moisture increases with temperature, so if the temperature changes without changing the absolute content of the atmospheric moisture, the relative humidity will also change.

    • n humidity The state of being humid; moisture; dampness; especially, a moderate degree of wetness which is perceptible to the eye or touch.
    • n humidity In meteorology, the amount of aqueous vapor in the atmosphere compared with that which is required to saturate it under the given condition as to temperature: specifically called relative humidity. If the atmosphere is completely saturated, the humidity is expressed as 100; if perfectly dry, as 0. The humidity varies widely in different places, and in the same place at different times.

God's pallid poor, His people, with scarcely space for breath;
So foul their teeming houses, so full of shame and taint,
They cannot crowd within them for the frightful fear of Death.
