Likewise, very low humidity can make us feel cooler than the actual temperature. This happens because the dry air helps sweat evaporate more quickly than usual. Beside above, what is an uncomfortable humidity percentage? Dew Point Temp. High humidity in winter isn't uncomfortable, but high summer humidity makes the air feel sticky. Air at 80 degrees with a relative humidity of percent contains 22 times more water than air at zero with humidity at percent.
Humidity levels above 55 percent can allow mould to grow, although levels of 70 percent are more ideal for mould growth. A reading of percent relative humidity means that the air is totally saturated with water vapor and cannot hold any more, creating the possibility of rain.
If the air temperature is 75 degrees Fahrenheit 24 C and the relative humidity is percent , we feel like it's 80 degrees 27 C out. Every homeowner should own a hygrometer that measures temperature and relative humidity RH. High humidity can have a number of adverse effects on the human body. It can contribute to feelings of low energy and lethargy.
In addition, high humidity can cause hyperthermia — over-heating as a result of your body's inability to effectively let out heat. Humans are very sensitive to humidity , as the skin relies on the air to get rid of moisture. If the air temperature is 75 degrees Fahrenheit 24 C and the relative humidity is percent, we feel like it's 80 degrees 27 C out, and you start praying that you had the air conditioner serviced last fall. Here's my best advice: Don't do strenuous exercise outside.
If you want to do sports, find an indoor location. Wear loose, light clothing. Go for light colours and natural fabrics like cotton and linen.
Drink lots of water. Stay inside at noon. The level of moisture in the air affects the elasticity of our vocal cords. Singers can tell you that it is harder to carry a tune in a dry environment. More recently, researchers theorized that speech was one of many human behaviors adapted to fit environment.
After looking at more than 3, languages, they discovered that tonal languages, like Chinese and Vietnamese, rarely developed in dry climates. To understand how it worked, you need to know a thing or two about hair. In , Horace Benedict de Saussure, a Swiss physicist and geologist, made the first hair hygrometer, using a human hair to measure humidity. A single strand of hair has many layers.
The inner layer is filled with proteins called keratins that bind to each other, giving shape to your luscious locks.
These proteins bind by forming tough disulfide bonds or weaker hydrogen bonds. You can thank hydrogen bonds for the funny way your hair dries naturally after getting out of the shower. Water molecules two hydrogens and an oxygen are soaked up by your hair and act as a bridge linking keratin molecules together in place. These hydrogen bonds keep your hair fixed in shape until you wet it again, allowing new hydrogen bonds to form. In high humidity, water molecules in the air find their way into straight strands.
As hydrogen bonds connect keratin proteins, hair starts to fold back on itself and curl. Frizzy fly aways occur when hair folds back enough to break the cuticle — or the outer layer of hair that looks like dragon scales under a microscope. The drier the hair, the more likely it is to soak up moisture in the atmosphere. So damaged hair — scorched by curling irons or parched from over shampooing — is often treated with moisturizing salon products.
Enter hygrometer. Saussure attached one end of a inch piece of human hair to a screw. The rest of the strand he maneuvered through a pulley and attached to a weight.
As the hair took on moisture, the strand curled and shortened moving the pulley and lifting the weight. Saussure could then calculate how much humidity was in the air based on how much the weight moved. The hair hygrometer can be made more sensitive by dipping the hair in alcohol and removing any oils that might prevent the strand from soaking up moisture.
Even professional summer athletes have to adjust for changes in humidity. A baseball pitch can change position by an eighth of an inch for every 20 percent drop in relative humidity.
That might seem like a small amount to the average person, but for a major league player, that could be the difference between a fly ball and a grand slam. In , the Colorado Rockies started storing their baseballs in humidors to keep them wetter and bouncier. Homeruns are more frequent at high altitude venues that get little humidity, like Coorers Field.
But storing the balls in humidors helped decrease homeruns by roughly 25 percent , said Alan Nathan, a physics professor at University of Illinois at Urbana-Champaign. When we exercise in hot temperatures, our bodies sweat to cool down. In dry air, the sweat evaporates quickly. If there is not enough humidity, it can cause electric charges and static electricity within the air. It may also cause people to feel itchy because of drying out their skin.
By learning more about humidity percentage and what it means, you can start to take greater control of your work environment. You may find that by establishing the right percentage, you can eliminate a significant amount of dust and airborne particles that circulate within your environment.
It can also make it easier to keep your employees comfortable so that they are more productive throughout the workday. Contact Smart Fog Inc today to learn more about commercial humidification and how to find the right percentage of humidity for your work environment.
