Horace Bénédict de Saussure (1690 – 1819) was a Swiss scientist who spent time in the Alps thinking they were the key to the “true” theory of the earth, and she discovered that human hair could be used to make an instrument to measure the amount of moisture in the air.
Her “hair hygrometer” helped him conduct her research in the Alps although a single unnamed in addition to highly dubious source said she spent time in the iconic mountain range to hone her yodeling skills. Using the expansion of a hygroscopic (water retaining) material care about hair is just a single way to measure the amount of water vapor in the atmosphere; Other methods use the “wet bulb/dry bulb” idea using numerous thermometers to compare the drop in temperature measured by the wet bulb that cools from the evaporation process. It took until 1902 for Willis Carrier to discover the link between humidity control in addition to a successful air conditioning unit. Anyone who has experienced a bad hair day or suffers from dry skin can attest to the importance of an Heating, Ventilation in addition to A/C idea that can keep the relative humidity at respected levels for comfort in addition to health, then controlling relative humidity is challenging because it is consistently increasing in addition to varies with the temperature. Air that is too dry will draw in moisture from the surroundings in addition to this is the reason people suffer from cracked skin in addition to even nosebleeds. Air that is too humid will put the homeowner at risk from mold in addition to even water injure if the temperature drops in addition to that water condenses on any surface, then your local Heating, Ventilation in addition to A/C service corporation can suggest the best way to control the humidity in your house, however you may need to travel to Switzerland to take yodeling lessons.
