hey dr. Berg here in this short video we're going to talk about the water a myth I know you were taught that you need to drink eight glasses of water a day I was taught that everyone knows that
2
that's what they say you need to do well someday I'm gonna find who they is because every time I find out a concept that everyone is doing because we just have to do it I'm suspect because it turns out most of
3
those recommendations end up to be false down the road so I guess the common thought is you have to drink half of your body weight in ounces so if I'm 200
4
pounds that's a hundred ounces that's twelve and a half glasses of water a day that's a lot of water and that's eight ounce glasses okay so let's just go
5
through this okay number one sixty percent of the body is water is that true no it's not true in fact zero percent of your body is water not one millimetre of your body is pure water it's all electrolyte fluids
6
you got your blood you live your urine all these fluids are electrolytes that's minerals it's sodium potassium calcium and a lot of other stuff in these fluids it's not just pure water so that's kind of a a falsity
7
number two the body doesn't know when it's thirsty I love this well first of all it does know when is thirsty you can perceive thirst hunger hot cold
8
temperature you can perceive a lot of things you have 52 perceptions of perceiving a lot of stuff so when someone tells you well sometimes when you're hungry you're really thirsty they're just making stuff up okay all
9
right that's a false all right so now number three water flushes out the fat so you need to drink more water because it helps you with losing weight there's
10
never been one person that lost even an ounce of fat by drinking more water it's a myth you can't lose weight by drinking more water because fat is fat soluble
11
it's not water soluble it doesn't dissolve by pouring more water on to it it's not going to happen try this take a slab of bacon fatty bacon and pour water and shake it up and see if it dissolves I tell you the stuff
12
that people believe it's incredible or they say drink more water because you're going to eat more eat less calories right because it's you're going to not be as hungry well yeah until you have to use the bathroom all right number four water flushes out toxins
13
well again toxins are fats Seibel they're not water-soluble and that would be like pesticides insecticides herbicides drugs they're all fat soluble
14
they're not water soluble so it's not going to flush anything out it's going to get stuck in the fat so drinking more water is not going to flush those out okay number five water helps dry skin not true dry skin is a deficiency of
15
vitamin A and that's in the skin that is in the eyes it's in the dry mouth your
16
body will dry out when it doesn't have the oils in the fat not the water same thing with your joints your joints are lubricated and your your skin is
17
lubricated and it will look young when you have oil and fat but it's not water the people that drink the most water actually are the most dehydrated now how
18
can that be because the the difference in electrolytes there's a condition called hyponatremia and that is a condition where you can die of and it's drinking too much water because it's going to flush out all the electrolytes
19
and the cells are going to swell because they have no electrolytes to mobilise the fluid even your brain will swell you can even have a coma a heart attack
20
enlarged liver okay seizures so all these things can come by drinking so much water alright so I probably drink on a given day maybe two maybe three
21
cups of water a day that's what I drink your body adjust if you drink less you'll pee less if you drink more you'll pee more your body is always trying to
22
maintain natural balance I personally drink Pellegrino because I like the carbonation some people don't I like this it's mineral water naturally from the I think it's Italy and this is what I drink but you could just drink
23
filtered water but here's the thing make sure you only drink when you're thirsty and if you have someone pushing this water on you just go ahead and send this
24
video I'll see you in the next video

練習のコツ
この動画のスピードは比較的早めですが、影響を受けずにシャドーイングを行うためのいくつかのテクニックを紹介します。まず、リスニングをする際に、理解できない部分を繰り返し再生して、音のつながりを意識しましょう。特にshadowspeakを意識しながら、言葉の流れを掴む練習が有効です。次に、映像を見ながら音声を真似することで、英語の発音を良くすることができます。
また、英語の発音を良くするためには、息を吸い込むタイミングや声の抑揚を意識してみてください。例えば、ドクター・バーグが話す際のリズムや強弱に注目し、そのスタイルを模倣しながら話すと、より自然になります。何度も繰り返すことで、より効果的に英語シャドーイングを行い、スピーキングの力を高めることができるでしょう。
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。
