So a couple of years ago, a woman I know who I'll call Maya, went through a lot of big changes in a short amount of time.
0:04.29 – 0:12.18 (7.9s)
2
She got married.
0:12.22 – 0:13.38 (1.2s)
3
She and her husband moved for his job to a new city where she didn’t know anyone.
0:13.43 – 0:17.76 (4.3s)
4
She started a new role working from home, all while managing her dad's new diagnosis of dementia.
0:17.81 – 0:23.98 (6.2s)
5
And to manage the stress of all this change, Maya doubled down on her physical and mental health.
0:24.69 – 0:30.94 (6.3s)
6
She exercised almost every day, she ate healthy foods, she went to therapy once a week.
0:30.99 – 0:35.99 (5.0s)
7
And these actions really helped.
0:36.32 – 0:37.95 (1.6s)
8
Her body got stronger.
0:37.99 – 0:39.66 (1.7s)
9
Her mind got more resilient, but only up to a point.
0:39.70 – 0:43.54 (3.8s)
10
She was still struggling, often losing sleep in the middle of the night, feeling unfocused, unmotivated during the day.
0:44.33 – 0:51.26 (6.9s)
11
Maya was doing everything that doctors typically tell us to do to be physically and mentally healthy, and yet something was missing.
0:51.30 – 0:59.68 (8.4s)
12
What if I told you that what was missing for Maya is also missing for billions of people around the world, and that it might be missing for you?
1:01.06 – 1:09.86 (8.8s)
13
What if I told you that not having it undermines our other efforts to be healthy and can even shorten your lifespan?
1:10.86 – 1:18.28 (7.4s)
14
I’ve been studying this for over a decade, and I've discovered that the traditional way we think about health is incomplete.
1:19.95 – 1:27.96 (8.0s)
15
By thinking of our health as primarily physical and mental, we overlook what I believe is the greatest challenge and the greatest opportunity of our time.
1:28.46 – 1:38.64 (10.2s)
16
Social health. While physical health is about our bodies and mental health is about our minds, social health is about our relationships.
1:39.30 – 1:50.19 (10.9s)
17
And if you haven't heard this term before, that's because it hasn't yet made its way into mainstream vocabulary, yet it is equally important.
1:50.65 – 1:59.32 (8.7s)
18
Maya didn't yet have a sense of community in her new home.
2:00.16 – 2:03.45 (3.3s)
19
She wasn't seeing her family, or her friends or her coworkers in person anymore, and she often went weeks only spending quality time with her husband.
2:03.45 – 2:12.04 (8.6s)
20
Her story shows us that we can't be fully healthy, we can’t thrive, if we take care of our bodies and our minds, but not our relationships.
2:12.04 – 2:22.31 (10.3s)
21
Similar to Maya, hundreds of millions of people around the world go weeks at a time without talking to a single friend or family member.
2:23.72 – 2:33.15 (9.4s)
22
Globally, one in four people feel lonely.
2:34.28 – 2:37.74 (3.5s)
23
And 20 percent of adults worldwide don't feel like they have anyone they can reach out to for support.
2:38.49 – 2:44.62 (6.1s)
24
Think about that.
2:45.25 – 2:46.41 (1.2s)
25
One in five people you encounter may feel like they have no one.
2:46.75 – 2:50.92 (4.2s)
26
This is more than heartbreaking.
2:52.38 – 2:54.92 (2.5s)
27
It's also a public health crisis.
2:54.96 – 2:57.22 (2.3s)
28
Disconnection triggers stress in the body.
2:57.55 – 3:00.18 (2.6s)
29
It weakens people's immune systems.
3:00.22 – 3:02.89 (2.7s)
30
It puts them at a risk, greater risk, of stroke, heart disease, diabetes, dementia, depression and early death.
3:02.93 – 3:11.15 (8.2s)
31
Social health is essential for longevity.
3:11.65 – 3:14.61 (3.0s)
32
So you might be wondering, what does it look like to be socially healthy?
3:16.03 – 3:19.86 (3.8s)
33
What does that even mean?
3:19.86 – 3:21.24 (1.4s)
34
Well it’s about developing close relationships with your family, your friends, your partner, yourself.
3:21.53 – 3:28.08 (6.5s)
35
It's about having regular interaction with your coworkers, your neighbors.
3:28.58 – 3:32.92 (4.3s)
36
It's about feeling like you belong to a community.
3:32.92 – 3:35.50 (2.6s)
37
Being socially healthy is about having the right quantity and quality of connection for you.
3:36.25 – 3:42.59 (6.3s)
38
And Maya's story is one example of how social health challenges come up.
3:43.84 – 3:48.18 (4.3s)
39
In my work, I hear many others.
3:48.22 – 3:50.56 (2.3s)
40
Stories like Jay, a freshman in college who’s eager to get involved in campus yet is having a hard time fitting in with people in his dorm and often feels homesick.
3:50.60 – 4:00.61 (10.0s)
41
Or Serena and Ali, a couple juggling the chaos of young kids with demanding jobs, they rarely have time to see friends or spend time one-on-one.
4:01.15 – 4:10.21 (9.1s)
42
Or Henry, recently retired, who cherishes time with his spouse and yet feels untethered without his team anymore and wishes he could see his kids and grandkids more often.
4:11.00 – 4:22.01 (11.0s)
43
These stories show that social health is relevant to each of us at every life stage.
4:22.47 – 4:29.14 (6.7s)
44
So if you're not sure where to start, try the 5-3-1 guideline from my book.
4:29.77 – 4:34.52 (4.8s)
45
It goes like this.
4:34.56 – 4:35.86 (1.3s)
46
Aim to interact with five different people each week, to strengthen at least three close relationships overall, and to spend one hour a day connecting.
4:35.90 – 4:46.45 (10.6s)
47
Let's dig into these.
4:46.45 – 4:47.83 (1.4s)
48
So first, interact with five different people each week.
4:48.20 – 4:52.04 (3.8s)
49
Just like eating a variety of vegetables and other food groups is more nutritious, research has shown that interacting with a variety of people is more rewarding.
4:52.08 – 5:01.84 (9.8s)
50
So your five could include close loved ones, casual acquaintances, even complete strangers.
5:01.88 – 5:07.09 (5.2s)
51
In fact, in one study that I love, people who just smiled, made eye contact and chit-chatted with a barista, felt happier and a greater sense of belonging than people who just rushed to get their coffee and go.
5:07.14 – 5:19.31 (12.2s)
52
Next, strengthen at least three close relationships.
5:20.07 – 5:23.78 (3.7s)
53
OK, we've all heard of a to-do list, but I would like to invite you to write a to-love list.
5:24.24 – 5:30.41 (6.2s)
54
Who matters most to you?
5:31.33 – 5:33.16 (1.8s)
55
Who can you be yourself with?
5:33.20 – 5:35.29 (2.1s)
56
Make sure that you invest in the names of at least three of the people that you write down.
5:35.33 – 5:40.63 (5.3s)
57
By scheduling regular time together, by showing a genuine interest in their lives, and also by opening up about the experiences that you're going through.
5:40.67 – 5:49.26 (8.6s)
58
And I'm often asked, does it have to be in person?
5:49.64 – 5:52.18 (2.5s)
59
Does texting count?
5:52.22 – 5:53.73 (1.5s)
60
Studies have shown that face-to-face is ideal, so do that whenever possible.
5:54.31 – 5:58.31 (4.0s)
61
But there are absolutely still benefits to staying connected virtually.
5:58.31 – 6:02.11 (3.8s)
62
And last, spend one hour a day on meaningful connection.
6:02.90 – 6:07.49 (4.6s)
63
OK, if you're an introvert, right now you're probably thinking one hour sounds like a lot.
6:07.49 – 6:13.04 (5.5s)
64
I get it.
6:13.49 – 6:14.70 (1.2s)
65
It might be surprising, but I'm actually also an introvert.
6:14.70 – 6:18.00 (3.3s)
66
However, keep in mind that just like getting eight hours of sleep at night, the exact amount that's right for you personally might be higher or lower.
6:18.79 – 6:27.30 (8.5s)
67
But if you are thinking that one hour a day sounds like way too much because you're just way too busy, I challenge you.
6:28.26 – 6:35.31 (7.0s)
68
Adults in the US spend an average of 4.5 hours each day on their smartphones.
6:35.85 – 6:40.90 (5.0s)
69
So instead of scrolling on social media, text a friend.
6:41.36 – 6:45.40 (4.0s)
70
Instead of reading news headlines, write a thank-you card.
6:45.94 – 6:49.66 (3.7s)
71
Instead of listening to a podcast, call a family member.
6:50.32 – 6:53.62 (3.3s)
72
Maya put this into practice by scheduling recurring hangouts with a new local friend that she made, by attending community events and dropping cards off in her neighbors mailboxes, by planning trips to see family and inviting friends in other cities to come visit.
6:54.95 – 7:12.05 (17.1s)
73
And bolstering her social health made more of a difference than focusing solely on her physical and mental health ever could.
7:12.10 – 7:21.19 (9.1s)
74
And I know this because Maya is actually me.
7:21.65 – 7:26.48 (4.8s)
75
I am so passionate about sharing tools to be socially healthy because honestly, I need them too.
7:28.82 – 7:34.41 (5.6s)
76
And the 5-3-1 guideline is one way that we can be proactive and intentional about our relationships.
7:34.70 – 7:41.67 (7.0s)
77
And that is really the point.
7:41.71 – 7:43.33 (1.6s)
78
Be proactive and intentional about your social health.
7:43.38 – 7:47.17 (3.8s)
79
So zooming out beyond the steps that you and I take individually, together, we need to shape a society that thrives through social health.
7:48.55 – 7:57.64 (9.1s)
80
Over the next decade, I envision educators championing social health in schools.
7:58.10 – 8:03.27 (5.2s)
81
And just like kids build their physical muscles in gym class, they'll exercise their social muscles in connection class.
8:03.27 – 8:10.53 (7.3s)
82
Over the next decade, I see our cities and neighborhoods being designed with social health in mind, where vibrant gathering places foster unity and community builders are empowered to bring them to life.
8:11.24 – 8:23.71 (12.5s)
83
Over the next decade, I believe that social health will become as ingrained in our collective consciousness as mental health is today.
8:24.71 – 8:33.34 (8.6s)
84
Because not that long ago, mental health was a taboo topic shrouded in stigma.
8:33.38 – 8:38.35 (5.0s)
85
And now public figures talk openly about it, there's an entire industry to support it, and more and more people think of going to therapy like going to the gym.
8:38.35 – 8:47.98 (9.6s)
86
In this future, loneliness will subside, just like smoking subsided when we recognized and treated it as a public health issue.
8:49.19 – 8:57.49 (8.3s)
87
In this future, I hope that social health will become so deeply woven into the fabric of our culture that no one needs the 5-3-1 guideline anymore.
8:58.49 – 9:08.59 (10.1s)
88
So to get there, make relationships your priority not only for you, but also for the people you love.
9:09.84 – 9:17.89 (8.0s)
89
Because the beauty of nurturing your own social health is that it naturally enriches the social health of everyone you connect with.
9:17.93 – 9:26.02 (8.1s)
90
Thank you. (Applause)
9:26.85 – 9:34.95 (8.1s)
このレッスンについて
TED Talkのスピーカー、キャスリー・キラムは、「Why Social Health Is Key to Happiness and Longevity」という講演で、健康の概念に新たな視点を提供しています。一般的に重視される身体的・精神的健康に加え、「社会的健康 (Social Health)」が幸福と長寿にいかに不可欠であるかを詳しく解説しています。
この動画では、人間関係の重要性、孤独がもたらす心身への悪影響、そして社会的健康を育むための具体的な「5-3-1ガイドライン」が紹介されます。新天地での孤独に悩む女性「マヤ」の事例や、様々なライフステージでの人間関係の課題を通じて、社会的つながりの重要性が鮮やかに描かれています。
このコンテンツは、英語学習者にとって非常に有益です。感情や社会問題について意見を述べるための語彙やフレーズを学ぶことができ、英語スピーキング練習の絶好の機会となるでしょう。特に、人とのつながりや幸福に関する個人的な経験を語る際、また社会的なトピックについて議論する際の表現力を高めるのに役立ちます。IELTS対策として、社会問題や健康に関するエッセイやスピーキングパートのテーマとしても活用できます。
重要な語彙とフレーズ
- doubled down on
（～に二倍の努力をする、真剣に取り組む）
例: Maya doubled down on her physical and mental health.（マヤは身体的・精神的健康に真剣に取り組んだ。） - up to a point
（ある程度までは、限られた範囲で）
例: Her actions really helped, but only up to a point.（彼女の行動は確かに役立ったが、ある程度までだった。） - undermines our other efforts
（他の努力を台無しにする、弱体化させる）
例: Not having social health undermines our other efforts to be healthy.（社会的健康がないと、健康になろうとする他の努力も台無しになる。） - made its way into mainstream vocabulary
（主流の語彙になる、広く知られるようになる）
例: Social health hasn't yet made its way into mainstream vocabulary.（社会的健康という言葉はまだ主流の語彙にはなっていない。） - sense of community
（コミュニティへの帰属意識、共同体感覚）
例: Maya didn't yet have a sense of community in her new home.（マヤは新しい家でまだコミュニティへの帰属意識を持っていなかった。） - thrive
（成功する、繁栄する、生き生きと過ごす）
例: We can’t thrive if we neglect our relationships.（人間関係を疎かにすると、私たちは生き生きと過ごすことができない。） - public health crisis
（公衆衛生上の危機）
例: Disconnection is also a public health crisis.（孤立は公衆衛生上の危機でもある。） - untethered
（つなぎ止められていない、孤独な、不安定な）
例: Henry felt untethered without his team anymore.（ヘンリーはもうチームがいないことで孤独を感じていた。）
この動画の練習のコツ
このTED Talkは、英語の流暢さを高めるための優れた教材です。特に、キャスリー・キラム氏の話し方は明瞭で、適切なポーズとイントネーションが特徴的です。以下の点を意識して練習してみましょう。
- シャドーイングで話速とリズムを掴む:
スピーカーの話し方は、おおよそ中程度の速度で、非常に聞き取りやすいです。まずは、スピーカーの声に遅れないよう、完全に真似て話すシャドーイングに挑戦しましょう。特に、文の区切りや強調したい単語でのポーズ、そして感情を込めた話し方（例: "This is more than heartbreaking."）を意識的に再現することで、自然な英語のリズムと流れを体得できます。
- 発音練習とアクセント:
標準的なアメリカ英語のアクセントです。特に、"social health"というキーフレーズや、"longevity"、"resilient"、"disconnection"といった少し長めの単語の発音練習に注力してください。単語単体の発音だけでなく、文中の単語同士のつながり（リエゾン）にも注意して、よりネイティブに近いサウンドを目指しましょう。
- トピックの難易度とIELTS対策:
「社会的健康」というトピックは、個人的な経験から社会全体の問題まで幅広く応用できます。スピーカーが「マヤ」のような具体例を挙げる部分では、ストーリーテリングのスキルを磨く練習になります。また、孤独が健康に与える影響や、人間関係の重要性を説明する箇所は、IELTS対策のスピーキングパート2やライティングパート2で社会問題や個人の幸福について意見を述べる際の表現の参考になります。自分の言葉で要約したり、賛成・反対の意見を述べたりする練習も取り入れましょう。
- 説得力のある話し方:
スピーカーは聞き手に語りかけるような問いかけ（"What if I told you that..."）や、データを用いた論拠（"one in four people feel lonely"）を巧みに使って、メッセージに説得力を持たせています。これらの表現方法を真似ることで、英語スピーキング練習における表現の幅が広がり、より効果的に自分の考えを伝えられるようになるでしょう。
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。
ShadowingEnglishでの効果的な学習方法
- 動画を選ぶ: 自然で明瞭な英語が使われているYouTube動画を選びましょう。TED Talks、BBC News、映画のシーン、ポッドキャスト、IELTS模範解答などが最適です。URLをコピーして検索バーに貼り付けてください。短い動画（5分以内）や、自分が本当に興味を持てるテーマから始めるのがコツです。
- まず聞いて内容を理解する: 最初は1倍速でただ聞くだけにしましょう。まだ繰り返す必要はありません。文の意味を理解し、話者がどのように単語を強調し、音を繋げ、間を取っているかに注目してください。内容を把握してからシャドーイングに入ると、はるかに効果的です。
- シャドーイングモードを設定する:
- Wait Mode（待機モード）:
+3sまたは+5sを選ぶと、動画が一文を読み終えた後に自動で一時停止し、繰り返す時間が生まれます。完全に手動でコントロールしたい場合はManualを選んでNextを自分で押しましょう。 - Sub Sync（字幕同期）: YouTubeの字幕と音声がずれることがあります。
±100msで調整して、正確なタイミングで追えるようにしてください。
- Wait Mode（待機モード）:
- 声に出してシャドーイングする（最重要）: ここが練習の本質です。文が流れると同時に——または一時停止中に——はっきりと自信を持って声に出して繰り返しましょう。ただ単語を読むだけでなく、話者のリズム、強調、高低、連音をそっくりそのまま真似することが大切です。「影」のように話者に重なるのが理想。Repeat機能を使って同じ文を何度も繰り返し、自然に出てくるまで定着させましょう。
- 徐々に難易度を上げて続ける: 一つのパッセージに慣れたら、さらに挑戦してみましょう。速度を <code>1.25x</code> や <code>1.5x</code> に上げれば、高速の言語反射を鍛えられます。Wait Modeを <code>Off</code> にして連続シャドーイングするのが最も上級で効果的なモードです。毎日15〜30分継続すれば、数週間で目に見える変化を実感できます。
