Why do we toss and turn on a hot night?
You're lying in bed on a hot summer night. The sheets feel warm. Your pillow is warm. Even the air is warm. And somehow, no matter how you arrange yourself, you just can't get comfortable. You flip to the cool side of the pillow. You stick one leg out. You roll over. Again. And again.
