Mariah Carey sleeps in a steam room to protect hervoice.The 'Hero' singer has revealed her bedroom is a humidified chamber which keeps her vocal chords in the best possible condition.Mariah told V magazine: "Literally, I'll have twenty humidifiers around the bed. Basically, it's like sleeping in a steam room. The bed is all terry-cloth, the ceiling is pitched so the water can't fall on my head, and it drips down to my side, and the TV is behind glass."The singer also confessed she feels under pressure to look sexy, and that she can't help it when her image appears over the top. She said: "I think that a lot of women are just trying to live up to the stereotypes and to the standard that's set on TV and in magazines, which is air brushed women who weigh 3 pounds."And it's not fair. It's not easy. But everybody gets really protective of me. They're, like, 'Be less sexy.'""If I look too sexy it's not intentional - if you film my body a certain way, it's gonna look like a certain way. But honestly, I've been the same way since I was a little kid. Like, I'm just emulating whatever's on a magazine."
