Dry winter air may not be visible to the naked eye, but its effects can wreak havoc on everything in its path, including your skin and hair, as well as precious items in your home like family heirlooms, photographs and artwork.
In partnership with third-party environmental scientists from Environmental Heath & Engineering (EH&E), an environmental consulting and engineering services firm, EH&E placed grapes in a controlled low-humidity environment to show the impact to other items in the home. They quickly wrinkled, shrank and became dried out over time, showing how moisture can evaporate during cool, dry months. The findings underscore the importance of adding moisture to indoor air when relative humidity levels drop, to help reduce negative effects on similar items and on those living inside the home.
"As cold temperatures set in during fall and winter months, humidity levels drop because cold air is unable to hold as much moisture as warm air. Indoor humidity levels can be as low as 10 percent- drier than the Sahara Desert," said Dr. Ted Myatt, ScD, who led the study by Environmental Heath & Engineering (EH&E). "These experiments show the value of maintaining optimum relative humidity levels between 40 to 60 percent. This can be done by using a humidifier to add moisture to the air to help alleviate the effects of dry air on the home and body, including dry skin and hair, similar to what was observed with the grapes."
