Sleeping more than 15 hours a night is way beyond the recommended 7-8 hours a day for human adults. "I've got to sleep 15 hours to sing the way I want to," Mariah Carey told Interview magazine in 2007. Well, sleep varies across ages and are impacted by lifestyle and health. But this award winning Diva Mariah Carey sleeps 15 hours a night in a room full of air humidifiers before her live concerts. "It's bleak, but you gotta do what you gotta do… I live in my own little universe."
Moisture is everything for Mariah because she needs to take care of her five-octave vocal range referred to as the "songbird supreme" by the Guinnes World Records. One's vocal folds require moisture to work effectively. Ideally wet enough to vibrate up to 1700 times every second.
Homes with dry air only need one humidifier, but Mariah prefers to sleep with a whopping 20 humidifiers in her sleeping quarters because she thinks that it can aid her voice by keeping her surrounding atmosphere moist. Plus it gives her healthier skin and/or allergy relief. "Literally, I'll have 20 humidifiers around my bed," she told V magazine. "Basically, it's like sleeping in a steam room." It was Luther Vandross from whom she learned this trick.
Furthermore, there are other singers that were rumored heavily to take a humidifier wherever they go, especially during a tour of before another important performance. They are Mary J. Blige, Celine Dion and Britney Spears.
