I'm currently developing a character concept for a Moon Druid I'll be playing in Storm King's Thunder soon, and I've been thinking about going with a Water Genasi.
The more human-looking have fiery red hair that writhes under extreme emotion, while more exotic specimens sport actual flames dancing on their heads.

Now, as badass as this looks, I can't help but wonder - how does this guy sleep? I mean, anything he rests his head on will inevitably catch on fire, unless he does it dwarf-style and sleeps on stone. So what, he has to use fire retardant pillows?
Is there any lore from previous editions - or 5e lore that I've overlooked - that explains how fire genasi with flaming hair sleep?
(For example, something that states "a fire genasi's flaming hair is magic and doesn't ignite stuff".)
