Alanis Morissette has a fear of air conditioning - because the fumes from the coolant destroy her voice.
The singer insists she isn't being difficult when she requests the units be turned off wherever she goes, claiming it's simply a danger to her vocal chords.
She says, "I refuse to go into rooms with air conditioning. People think I'm some sort of diva because I won't even put a foot into a place if the air con is on. It's not about being a diva - it's about my health. Within a matter of minutes of being exposed to air conditioning, my body goes into meltdown, and within three hours I'll contract laryngitis and won't be able to speak, let alone sing."
