I you Jesy's

0:02

bet you didn't know. Interesting

0:05

trivia that's hopefully going to make you go, Oh,

0:07

let's talk about yawns. Come on, you've

0:09

done it. I've done it. We've all been caught doing

0:11

it right. It's involuntary and it comes so

0:13

naturally and and if you think about it. Come on. Admit

0:16

it, it's quite a shock when you yawn, right? It's like, Oh, it's

0:18

like, it's like a relief. Sometimes,

0:20

you know, de-stress us. Birds

0:22

do it. Fish do it. In fact, nearly

0:24

all cold and warm blooded vertebrates

0:27

do it, with the exception of giraffes and whales,

0:29

which have not yet been caught

0:32

yawning. OK, but how? Why

0:34

animals and human beings yawn. The

0:36

real reason confirmed reason

0:38

is still quite a bit of mystery. There are some theories,

0:41

though. First one is that we yawn when

0:43

we're sleepy aboard. That has led

0:45

recent research to suggest that is used

0:47

to increase vigilance. So,

0:49

you know, because you know your sleep and every

0:52

focus, you yawn so that you help you to focus.

0:54

Now, another theory is that yawning helps to cool the

0:56

brain, protecting cerebral activity and

0:58

boosting efficiency. Now what is known as

1:00

a factor, though, and this really quite

1:02

blew my mind, is that the average human?

1:04

You and I, we will yawn around 250000

1:08

times over the course of our

1:10

lives. And do you know babies?

1:13

Babies in the womb yawn

1:15

from as early as 12 to 14

1:18

weeks? One

1:20

certain disease that you

1:22

didn't know.
