Scientists from Tufts University have created the Uji illuminated shower head that gradually changes from green to red while in use, reminding users when to step out of the shower. Once the Uji has turned red, it makes users realize how much time is passing.
The current prototype is set to turn fully red after seven minutes, although the duration may be adjustable on a commercial version, according to a report.
According to its inventors, a six-month study indicated that the Uji reduces showering time by an average of 12 percent, which should add up to a savings of approximately USD 85 a year in a home setting. In a university setting, that figure goes up to USD 200 a year.
"It encourages [people] to take shorter and more energy efficient showers by letting people become aware of how long they're in the shower, we've actually been able to cut shower time by 12 percent," said one of the co-inventors, Brett Andler.
Inventors expect the Uji shower head, priced at about USD 50, to be available for sale early next year.
