Our Bodies Are Getting Colder
You’ve had your temperature checked before, right?
If your body temperature is too
high
or too low, it means you’re not
well.
體溫太高或太低 ….代表你生病了.
But your body temperature should usually be about the same each time you check it.
That is because our bodies are
really
good at controlling their own
temperature.
人的身體很會控制體溫.
If you’re hot you will probably sweat.
熱的時候會流汗
And if you’re cold you
might get goosebumps.
感覺冷會起雞皮疙瘩.
These are just some of the ways our bodies control our temperature.
But did you know bodies are actually slowly getting colder and colder? Yep,
it’s true.
Researchers found out that humans’ average body temperature became
half a degree cooler in the last 200 years or so.
人的體溫變低了!
That may not sound like a lot, but it means our bodies are changing.
But …
why? Well, the truth is … we’re not quite sure.
It’s probably because of a
lot of reasons.
If you compare the world now to
200
hundred years ago, people have
better
medicine,
藥比以前有效，
more food,
更多食物，
and more information about what
is good for us and what is bad for
us.
We’re overall healthier.
基本上，我們現在比較健康!
We also have heating and air-
conditioning now, so our bodies
don’t
have to
work as hard to control our
temperature.
And that’s not the only thing that’s
changing … we’re getting taller,
heavier, and living longer too.
也活得比較久!
What all this means is that if you were born two-hundred years ago, you would
have probably looked a little bit different. And that’s pretty interesting.
