1. Why Do Babies Yawn?
- As I have already mentioned, ultrasound imaging revealed babies yawning before their birth. Scientists at Durham and Lancaster Universities states that the moment may be related to the maturation of the central nervous systems. ” It may be that in order to get part of the brain to mature in a correct way it needs a stimulus. Yawning maybe the stimulus.” they said.

- Recently, another physiological function of yawning has been proposed stating that yawning regulates the temperature of the brain. It might cool down the brain while the temperature increases.
- It also linked with actions like muscle stretching, joint movement and increased heart rate ( think early morning waking), yawning may be the way to gear up.
- Its theorized that yawning is a not a sign of sleepiness or boredom but it induces your brain to wake you up and makes more alert.
- A disproven theory is that we yawn to improve oxygen in the blood and reduce carbon dioxide. This seems logical since yawning can increase oxygen with a deep breath an expiration removes carbon dioxide than the usual breath buy research by putting up people in low oxygen and high carbon dioxide environments does not produce yawning.
