In all, yawning is not something done because a person is bored. It serves as a cooling agent of sorts as far as medical implications are concerned. Doctors may be able to use excessive yawning as a way to identify patients with conditions that affect temperature regulation.

“The brain is exquisitely sensitive to temperature changes and therefore must be protected from overheating,” they said in a University of Maryland news release. “Brains, like computers, operate best when they are cool.”

Sleep deprived people who rely heavily on melatonin may want to change their reliance on such pills. Though they may help, the question is how long. And if you want something better to act as a substitute, here is one called a Melatonin Skin Patch which can aid you even better.

The patch may be more effective than melatonin pills because oral melatonin wears off quickly while the dose from the patch lasts longer. The study, published this week in the journal Clinical Pharmacology & Therapeutics, only involved eight people. They were given a patch containing either 2.1 milligrams of melatonin or no drug. The researchers measured their sleep performance and the melatonin levels in their blood.

“And, importantly, melatonin levels rose gradually, such that the peak concentration occurred in the early evening, during the latter part of the bed rest. We know — and shift workers know — that this is a time during which it is particularly difficult to remain asleep,” Aeschbach said in a news release.
