Yawning
Yawning is familiar to everyone and
totally mysterious, as scientists continue to
puzzle over its possible functions.
Yawning is a behaviour found in fish, reptiles and
birds, as well as in humans. Described in ancient
times by Hippocrates (who thought it served to
evacuate fever), yawning did not become a subject of
serious interest until the advances achieved in
neuroscience in the 1980s.

Below are some of the facts you will find interesting

1. Thinking or reading about oscitation will make you
just do it. You will be yawning in a few minutes or
so…if not right now

2. There is still no clear basis regarding the
mechanism of yawning. Several causes have been
attributed to this activity. Hippocrates thought of
yawning as a way to decrease one’s fever, while
some modern scientists postulated it as the body’s
way of getting the oxygen that it needs. But that
theory is contradicted by modern science.

3. Yawning occurs as early as 20 weeks after
conception. Several 4D ultrasound image shows that
fetuses as young as 11 weeks old know how to yawn.
Experts attribute this to the development of the
brain during this stage in the womb.

4. The average yawn lasts 6 seconds. Heart rate
significantly increases during these 6 (or lesser)
seconds.

5. Yawning is truly contagious. This activity starts to
become ‘transmissible’ in the first 1-2 years of a
person’s life. Proof of yawning’s infectiousness?
Several studies show that when a single person in a
group begins to yawn, more than half of the
assembly will follow right after – in as short as 5
minutes. The other lesser half will be enticed to yawn
too.

6. Yawning is more contagious in best buddies.
Studies show that persons related to you – whether
genetically or emotionally – are most likely to ‘catch’
your yawn.

7. Yawning helps cool down the brain. Studies show
that yawning episodes increase during wintertime, in
order to usher cool exterior air to the individuals’
brains.

8. Yawning is an activity that can help athletes
prepare prior to a competition – you can ask Apolo
Ohno, a speedskater who is notorious for his pre-
contest yawning ritual. Since yawning cools the brain
(especially the frontal lobes), the athlete will be able
to improve his concentration and attention span prior
to the race.

9. Yawning often occurs when a person is bored, as
proven by a 1986 study of college students who
oscitated more during a lackadaisical color video
rather than a hard-hitting, head-banging rock music
vid

10. Animals yawn too! Biologists have observed this
activity in primates, specifically chimpanzees,
macaques and baboons. Dogs catch the
contagiousness of yawning too; you can expect your
pooch to do the deed right after you do.

11. While yawning is a normal bodily activity, too
much yawning might mean that you are suffering
from an underlying medical condition. Excessive
yawning is one of the ‘rare’ symptoms of heart
conditions, as oscitation is a result of vagus nerve
reaction. Too much Yawning might signify brain
illnesses as well.
