Yawning REVISED FROM GLASS EYE MEDICAL
For us, yawning is a natural consequence of fatigue and drowsiness. But in terms of medical evaporated save a lot of secrets that still need to be researched and revealed. In recent years, yawning has been believed to reduce anxiety and tension effectively.
Yawn, is a mechanism for vigilance, begins in the fetus in the first 20 weeks after conception. It
helps regulate circadian rhythms newborns, and this adds to evidence
that yawning is involved in the process of setting up and sleep. Because
circadian rhythms become out of sync when the normal sleep cycle is
interrupted, yawning helps reset the brain to reorganize drowsiness. Yawning may also ward off the effects of jet lag and reduce discomfort caused by the altitude.
In addition to activate the precuneus, yawning also regulates the temperature and brain metabolism. It takes a lot of nervous energy to stay awake alert, and when working the brain becomes less energy efficient. Yawning may be as a way to cool the brain is too active, especially in the frontal lobe area. Some researchers even argue that it is a primitive form of empathy.
on brain scans recently, suggests that yawning can evoke neural
activity in the brain that generate social awareness and create a
feeling of empathy. Precuneus
is part of the brain, a small part hidden in the folds of the parietal
lobe, which plays a central in awareness, self-reflection, and memory
retrieval. In part this is also the most frequently and most severely stricken with age-related diseases.
to Andrew Newberg, director of Penn's Center for Spirituality and the
Mind, yawning should be integrated into the exercise and stress
reduction programs, cognitive and memory enhancement exercises,
psychotherapy, and contemplative spiritual. And,
because the precuneus has recently been associated with a system of
neurons in the brain (which allows us to resonate with the feelings and
behaviors of others), yawning is believed can help to increase social
awareness, compassion, and effective communication with others. However
this is difficult for most popular, because of the stigma that can not
be described in a society which implies that it is not polite to yawn,
and most of us were taught this when we were kids.
