Rebekah Kelley Reviewer I was one of those overachiever kids.
2
12 things going at once,
3
already dreaming of changing the world.
4
And I was so excited to go to summer school at Yale when I was 16.
5
I didn't say I was cool.
6
The classes were tough and thought-provoking,
7
But that's when something strange started happening to me.
8
I'd be sitting in class,
9
completely engaged, when suddenly a fog rolled in.
10
My thoughts fuzzed, my senses dulled,
11
the world blurred, like someone was slowly turning a dimmer switch on my brain.
12
I'd pinch my thigh, tap my foot,
13
anything to fight this overwhelming urge to sleep.
14
Once I bit my tongue so hard it bled,
15
and then the thought would hit me like a hammer.
16
If I don't go to sleep right now, I'm going to die.
17
So somehow quietly, I'd excuse myself,
18
slip into a bathroom stall,
19
lean my head against the wall, and fall asleep.
20
When I told my family doctor,
21
she said, you're busy, and busy people are tired.
22
It felt dismissive, but also like some secret initiation into adulthood.
23
I had big dreams, a lot to accomplish,
24
so I figured I just had to get better at being awake.
25
When I started working in professional politics,
26
exhaustion was a badge of honor.
27
The later you stayed up,
28
the more coffee you drank,
29
the more worthy you felt.
30
Society convinced us that if we were tired,
31
we were doing it right.
32
In 2008, I joined the Obama Advance team,
33
the people responsible for everything from logistics to aesthetics on the campaign.
34
But the thing about Advance,
35
you're in a new city every four to six days,
36
regularly pulling all-nighters on behalf of the future president of the United States.
37
The stakes were high, it was fast-paced, everyone was exhausted.
38
I was surrounded by the best,
39
the brightest, and the busiest,
40
but I never saw them sneaking into the bathroom to nap like I did.
41
I thought I must be lazy,
42
that I lacked the willpower everyone else seemed to have.
43
And underneath all that drive,
44
I felt utterly alone in my inability to keep up.
45
As the years passed,
46
I kept bringing up my sleepiness to doctors who kept pushing the same glossy handouts on improving my sleep hygiene.
47
My gut knew something else was going on.
48
And then came the dreams.
49
I'd wake up, frozen in bed,
50
convinced something terrifying was in the room.
51
I could see it, but I couldn't move or scream.
52
One doctor said it was just me manifesting stress from my job.
53
One night, I woke to a child whispering,
54
can I hold your hand?
55
The next day, I saged my entire bedroom,
56
like never crossed my mind I might have a neurological disorder.
57
at 35 i hit my wall i could fall asleep
58
but i couldn't stay asleep i was awake most of the
59
night falling back asleep just before my alarm went off most
60
days i felt like a lunatic zombie barely holding it together
61
i would drop things suddenly in the middle of stressful meetings
62
at work at my wits end i begged my general practitioner for help she ordered an at-home sleep test
63
which came back negative for sleep apnea
64
and i was told you're fine i marched back into her office with a full defense that something else was wrong.
65
She stopped me mid-sentence and admitted,
66
we're officially beyond both our knowledge of sleep.
67
I was referred to a sleep specialist,
68
which is a doctor trained to diagnose and treat sleep disorders.
69
And two months later, after 19 years of symptoms,
70
shame, and self-doubt, I was diagnosed with narcolepsy,
71
a chronic neurological condition of the brain sleep-wake cycle.
72
And before you say 19 years, that's extreme.
73
It's not.
74
The average diagnosis period for narcolepsy is 8 to 15 years.
75
And that's because in medical schools worldwide,
76
doctors receive on average less than three hours of education on sleep total across their entire medical training.
77
No wonder no doctor thought my Why sleepiness was an issue or asked any follow-up questions?
78
Narcolepsy has five distinct symptoms that on their own seem completely unrelated.
79
Excessive sleepiness that can feel like you've been awake for 48 hours,
80
even after a full night's rest.
81
Nighttime hallucinations, sleep paralysis, disrupted sleep, and sometimes cataplexy.
82
A loss of muscle tone with strong emotions.
83
Which is why I don't have slides in this talk,
84
because I was afraid I would drop the remote.
85
I never walked into a doctor's office and listed them all together
86
because there was no way for me to know they belong to the same story.
87
The same way there was no way for me to know my tired was different.
88
But for one in five of us, our tired is different.
89
While narcolepsy might be rare,
90
it's estimated 20% of the population has a sleep disorder.
91
Everything from sleep apnea to chronic insomnia,
92
restless leg syndrome, and other conditions that quietly steal rest.
93
And only 18% of those people have actually been diagnosed,
94
which means as many as 50 million people in the United States
95
and hundreds of millions of people worldwide are walking around exhausted,
96
untreated, and thinking it's normal to feel this way.
97
We've been taught to push through exhaustion instead of asking about it.
98
This isn't an epidemic of laziness.
99
It's a failure of diagnosis.
100
We dismiss people with sleep disorders all the time.
101
We think sleep apnea only affects middle-aged men with thick necks and square jaws.
102
But it can affect anyone at any age and any size.
103
Now, thankfully, we've started to recognize that sleep is vital,
104
one of the most important things you can do for your physical or mental health.
105
When you get enough sleep,
106
your body performs quiet miracles,
107
repairing cells, balancing hormones, clearing toxins from your brain.
108
Sleep is where creativity is born,
109
memories are filed, and the subconscious gets to color outside the lines.
110
Sleep is the engine of productivity.
111
Now, good sleep hygiene matters,
112
but for the one in five of us living with a sleep disorder,
113
sleep hygiene alone isn't a cure.
114
No perfect bedtime routine, no weighted blanket,
115
no lavender spray on your pillow will keep your airway open at night.
116
Because when the problem is neurological,
117
structural, or biochemical, without medical intervention,
118
your body pays the price.
119
Aside from brain fog, loss of productivity,
120
and the dangers of drowsy driving,
121
over time, when sleep disorders go undiagnosed,
122
they silently break the body down from the inside out,
123
fueling inflammation, accelerating aging, driving insulin resistance,
124
and raising the risk of heart attack, stroke, even Alzheimer's.
125
This isn't just exhaustion.
126
It's a slow erosion of health, focus, and longevity.
127
But it's also an identity issue.
128
I didn't become a whole person until I was diagnosed with narcolepsy.
129
Before that, I was working or sleeping.
130
There was nothing in between.
131
But with treatment, the world came alive to me.
132
Colors got brighter.
133
I felt a full range of emotions.
134
I started having hobbies.
135
I found my voice.
136
Before my narcolepsy diagnosis, I didn't think I was creative.
137
In the last eight years of treatment,
138
I've written two pilot scripts,
139
wrote and published a whole book,
140
became a keynote speaker, and had articles published in national outlets.
141
Before my diagnosis, my world felt extraordinarily limited.
142
Now, there's no limit to my capacity.
143
So consider this, your activation,
144
your permission slip, your reclamation,
145
your literal wake-up call to question not just your sleep,
146
but how you feel during the day.
147
If something is off, ask for help,
148
demand answers, see a sleep specialist.
149
Not just for your health,
150
but for the idea, the project,
151
the relationship, the version of you that's waiting to wake up.
152
Because I want you to live your biggest,
153
most beautiful life, full of color,
154
curiosity, and awe, wild and wide awake.
155
So I'm asking you, is your tired different?

練習のコツ
この動画のなめらかなスピーチに合わせて、英語シャドーイングを行うことが重要です。まず、声のトーンやリズムを注意深く聴きながら、何度も繰り返し練習してみましょう。特に、感情のこもった部分や重要なフレーズでは、より強調して声に出すことが大切です。スピーチの速さは一定ではないため、shadow speak技術を活用し、理解しやすいペースで繰り返すようにしましょう。また、IELTS スピーキング対策にも非常に役立つ方法です。YouTubeで英語学習を進めながら、自分の発音やリズムを録音し、改善点を見つけるのも良いでしょう。
シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
