You may have heard the saying ‘the early bird gets the worm’,
but when it comes to humans, do morning people really have an advantage over night owls?
Does one come out on top as more intelligent or successful than the other in this battle over bed time?
The somewhat surprising truth is that we have little say in sleep preference,
as it’s almost entirely genetically pre-determined.
Chances are, if you’re a night owl, it was likely passed down from an ancestor who was also a night owl.
And from an evolutionary perspective, it makes sense; having individuals with varying sleeping patterns
would allow for better protection of a group throughout day and night.
Instead of everybody sleeping at one time, some people naturally stay up later,
and some wake up earlier, aware of threats or predators while other sleep.
But considering most modern societal activities happen between 9am-5pm, it may seem clear that night owls are put at a disadvantage.
And researchers have actually coined the term ‘social jet lag’ to describe the sleep deprivation many experience to accommodate social norms.
For night owls, this social jet lag feels like living in a different time zone every single day.
Considering chronic sleep deprivation has a direct effect on brain functioning,
it’s no surprise that studies report night owl university students have lower overall grades.
Not to mention early birds tend to display more positive social traits such as being proactive and optimistic,
and are less prone to depression, or addictions to nicotine, alcohol and food.
And we can see these traits represented physically in the brain - particularly the white matter which helps neurons communicate.
Night owls exhibit significantly less white matter and,
as a result, there are fewer pathways for feel good hormones such as serotonin or dopamine to travel through.
But it’s not all bad for the late nighters. In fact, they tend to be much more creative,
have been found to have higher cognitive abilities, and are known to be risk takers.
What they lack in white matter, they make up in cortisol levels.
This ‘stress hormone’ gets your body ready to face an immediate threat, contributing to their risk taking behaviour,
which studies show can translate into opportunities and potentially more financial gain.
Furthermore, even though morning people can be very energetic right after waking,
they tend to lose steam faster than night owls throughout the day.
Both sides perform equally well in reaction-time tests an hour after waking,
but after 10 hours of being awake, night owls perform significantly better.
Your inner clock is regulated by many proteins which are created from various genes in your DNA.
Studies have even shown that a single change of the genetic code, near a gene called Period 1,
can result in an hour difference in your waking time.
As crazy as it seems, scientists also found a correlation between these same genes and your time of death.
The early risers were more likely to die around 11am,
while the night owls were more likely to die before 6pm.
What about teenagers, you say? It’s true, most tend to be night owls due to the hormonal changes during puberty,
but this tends to wane out into your genetic default as you enter adulthood.
So while there may be some truth to early birds getting the worm,
night owls aren’t exactly lagging behind in life...they’re just lagging behind in time!

1the early bird gets the worm0.04
早起的人除了常用的early bird,我們也會說early riser 或 morning person。 還有很多店家常常會推出早鳥優惠,就是early bird discount。 夜貓子在英文裡面是night owl,也可以說late nighter 或 night person。

早睡早起: keep early hours
熬夜: stay up late/ burn the midnight oil

2come out on top0.11

3We have little say about...0.18
這句話的意思不是我們可以說的很少,而是說我們在這個方面沒有什麼發言權。 翻成白話就是,某件事「並非我們可以控制的」。

4Chances are...0.22
chances就是機會,這句話有「很有可能」的意思。也可以用It’s likely that...來替換。

5coin the term0.52
coin在這裡不是「硬幣」噢!coin有「創造字彙」的意思,所以影片的意思是,研究員「創造」出 “social jet lag” 這個字彙來形容夜貓子的人。

6inner clock2.13
咦?內部的時鐘? 就是「生理時鐘」的意思!
也可說是biological clock 或body clock。


【TED】Russell Foster:我們為什麼需要睡眠? Why do we sleep?

Why Does My Brain Sleep

7wane out2.44
wane這個字是「月虧」,相反月盈則是 “wax”。 wane out 有衰減,衰弱的意思。 我們中文常說「月有陰晴圓缺」,英文可以說 “Every flow must have its ebb”。 字面上的意思是,漲潮都會伴隨著落潮。
