The Yawn Explained: It Cools Your Brain : Discovery News
"It is interesting to note that instances of excessive yawning in humans may be indicative of brain cooling problems," Gallup, Jr., told Discovery News, pointing out that patients with multiple sclerosis often experience bouts of excessive yawning "and MS involves thermoregulatory dysfunction."
Well, that last bit just solidifies my belief that hypothalamus is geb0rked - one of its main functions is thermoregulation and I am ALWAYS either too hot or too cold. NEVER "just right" (other than fleetingly as it switches mode from cooling to heating). It probably also explains why this damned flu/fever is SO! UNCOMFORTABLE!!! for me.
