1-40. The Chemistry of Sleep

People today are in trouble with tons of information and stress, making it difficult to get a healthy sleep.

Recently there have been an increasing number of articles about sleep on various journals.

“Sleep is more about quality than length.”

“Sleep when you’re sleepy.”

There is a wide range of advice on sleep.

“Why We Sleep: Unlocking the Power of Sleep and Dreams”, which was published in the US in 2017 and became a best-seller, is about the power of sleep.

Matthew Walker, a professor at the University of California, Berkeley, who studies sleep, summarizes the results of his previous research.

In it, he described how to improve the quality of sleep.

First, sleep researchers recommend eight hours of sleep.

The reason for this is that the ratio of REM and non-REM sleep changes at the beginning (late night) and end (early morning) of sleep.

REM sleep is a dreaming state and non-REM sleep is a state in which the brain is resting, and the brain repeats this cycle while you sleep.

Studies show that the closer morning, the percentage of REM sleep is increased.

Therefore, the dreams you remember when you wake up are the dreams you were having just before you woke up.

In order to balance this REM and non-REM sleep, you have to sleep for 7-8 hours.

That’s why, Dr. Walker says, “Eight hours of sleep is necessary.”

There are many negative effects that lack of sleep can have on the body and mind, and usually you’re barely aware of them.

He warns against getting less than six hours of sleep because “sleeping in batches later doesn’t cancel out the fatigue.”

As a perpetual insomniac, this is very serious facts for me, too…

We want to be conscious of our daily sleep so that we don’t let the accumulation of a lack of sleep in our lives destroy our bodies.

In next article, I’ll introduce the basic rules of good sleep as recommended by sleep researchers…

1-39.「EGFマスト」

EGFは細胞表面に結合し、タンパク質チロシナーゼ活性を向上させます。

チロシナーゼ活性は多様な生化学反応を開始して、

最終的にはDNA結合と細胞増殖に導き、

新しい「娘細胞」が発生します。

年齢と共に体内EGFが減少すると、肌老化が加速します。

そこで
EGFを補給するとターンオーバーが促進し肌本来の美しさが戻ってきます。

年齢と共に出現した、シワ、シミ、タルミは諦めなくても良いのです。

そして最近では、
アトピーやアレルギーなどで弱って傷ついた肌が多く見られます。

EGFは、傷を受けた肌に欠かせない大切な働きをしていますので、そのような肌へも有効と考えます。

では、EGFなら何でも良いのか？？

注意すべき点は、EGFが非常に繊細であるということと、、

EGFは「活きた状態」でないと、美容効果を発揮することができないということです。

そのような理由からも、、

EGFを主要成分とし、
EGFの活性力をそのまま温存した「生プラセンタ」は

その驚異的活性数値からみても、

奇跡的な肌若返りの「秘薬」であること間違いなし！といえます。

1-39. EGF is essential

EGF binds to the cell surface and increases protein tyrosinase activity.

Tyrosinase activity initiates a variety of biochemical reactions that eventually lead to DNA binding and cell proliferation, resulting in the generation of new “daughter cells”.

As the concentration of the EGF in our body decrease with age, the skin’s aging process is accelerated.

Supplementing with EGF accelerates the turnover and restores the skin’s natural beauty.

You don’t have to give up on the wrinkles, spots, and sagging skin that appear with age.

And these days,

we see a lot of weak and damaged skin due to atopy and allergies.

Since EGF plays an important role in the skin that has been damaged, we believe it is effective for such skin.

So, is any EGF good for you?

It is important to note that EGF is very sensitive and,,,

That EGF must be in an “active state” to be able to exert its beauty benefits.

For this reason,

we can say that a “raw placenta” preserves the active power of EGF which must be definitely a miraculous skin rejuvenation “secret medicine”!

1-38.「肌の衰えについて」

ターンオーバー(皮膚の新陳代謝システム)が遅くなると、肌老化が加速します。

ここで改めて、肌老化の仕組みとEGFの重要性についてのおさらいです。

ー肌老化の仕組みー

私たちの皮膚は約４５日間のサイクルで新しくなります。
これをターンオーバー時間と呼びます。

新しい皮膚は表皮のもっとも深い層(基底層)で生まれ、
その「娘細胞」は形を変えながら表面の角質層に到達し、
最後は垢として脱落します。

ターンオーバー時間は年齢を重ねる毎に遅くなります。

ーEGFの必要性ー

この「娘細胞」を作るために基底細胞はさまざまな「生理活性物質」を必要とします。

その中で最も重要なファクターが上皮成長因子「ＥＧＦ」です。

このＥＧＦが年齢と共に減少し、肌の衰えにつながるのです。

ですので、積極的にEGFを補うことは、
肌老化にブレーキをかけると共にアンチエイジングには欠かせません。

年齢と共に加速する肌老化にとっての
「ＥGＦ」の効果性と重要度
お解り頂けましたでしょうか。

繰り返しますが、、

この「EGF」あくまでも活性力が要ですので、活きていなければ意味がありません！

1-38. Skin aging

When the turnover (the skin’s metabolism system) slows down, skin aging is accelerated.

Here’s another review of how skin aging works and the importance of EGF.

– Mechanism of skin aging –

Our skin renews itself in a cycle of about 45 days.
This is called the turnover time.

New skin is born in the deepest layer of the epidermis (the basal layer) and its “daughter cells” change shape to reach the surface stratum corneum and finally shed as plaque.

The turnover time increases with age.

– Necessity of EGF –

In order to make these “daughter cells”, basal cells require various “bioactive substances”.

The most important factor among them is the epidermal growth factor “EGF”.

This EGF decreases with age, leading to skin deterioration.

Therefore, actively supplementing EGF is essential for anti-aging because it can put the brakes on skin aging.

I hope you have understood the effectiveness and importance of EGF for skin aging that accelerates with age.

Again, this “EGF” is meaningless if its activity is not maintained, as its activity is very important!

Next time I’ll explain in more detail…
