Pop superstar Mariah Carey protects her voice while touring by going to bed early every night - and sleeping next to five humidifier machines.

The HONEY singer, 35, is so concerned with providing fans with a high quality performance, she even forces herself to remain mute for as long as possible.

She says, "If there's (a concert) the next day I come home and get right in bed to rest my voice.

"I've got five humidifiers by my bed. I zone out and try not to talk too much. It's very boring."
