Between 45% and 55% RH, static builds up at reduced levels, while humidity above 55% RH ensures that static will never build up. [11] The American Society of Heating, Refrigerating and Air Conditioning Engineers has traditionally recommended a range of 45–55% RH in data centers to prevent sparks that can damage IT equipment.

The Levoit Duual 200S Smart Humidifier is a compact and reasonably priced mister that can help maintain comfortable humidity levels in your home. ... The best sleep masks of 2025, according to ...
Much has been made about the dangerous pandemic pathogens flying around the air outside of our personal bubbles this year, but in the cold months ahead, the safety of indoor locations may be a ...
[citation needed] However, high humidity outdoors creates the need for careful attention to humidity levels indoors. High humidity give rise to mold growth and moisture indoors is associated with a higher prevalence of occupant respiratory problems. [citation needed] The "dew point temperature" is an absolute measure of the moisture in air ...
For example, in the range of normal temperatures, air at 68 °F (20 °C) and 50% relative humidity will become saturated if cooled to 50 °F (10 °C), its dew point, and 41 °F (5 °C) air at 80% relative humidity warmed to 68 °F (20 °C) will have a relative humidity of only 29% and feel dry.
A hygrometer is an instrument which measures the humidity of air or some other gas: that is, how much of it is water vapor. [1] Humidity measurement instruments usually rely on measurements of some other quantities such as temperature, pressure, mass, and mechanical or electrical changes in a substance as moisture is absorbed.
A generalized view of the heat index showing how the perception of heat by the human body increases with temperature but more rapidly at higher humidity levels. The heat index of a given combination of temperature and humidity is defined as the dry-bulb temperature which would feel the same if the water vapor pressure were 1.6 kPa. Quoting ...
The wet-bulb temperature is the lowest temperature that may be achieved by evaporative cooling of a water-wetted, ventilated surface.. By contrast, the dew point is the temperature to which the ambient air must be cooled to reach 100% relative humidity assuming there is no further evaporation into the air; it is the temperature where condensation (dew) and clouds would form.
