1. Help your lungs detoxify, don't harm them
Advice:
''So you see, those suffering from lung diseases often cough during the 'dần' hour, from 3 to 5 AM. The lungs exist for breathing. Between 3 and 5 AM, the lungs detoxify.
If you wake up early in the morning, the air is the freshest because the dust has settled overnight, and the positive energy begins to flow, making it the perfect time to breathe deeply and actively, which helps the lungs expel toxins.
Waking up at this time is ideal. That’s why the saying ‘A day’s essence is in the ‘dần’ hour’ exists.
As long as you’re breathing, you’re alive. If you exhale and cannot inhale, that’s the end of life. Life is measured by each breath. Yet, many people, possibly even you, take their breath for granted. Only when you're congested or short of breath do you realize the value of every breath.
Breathing is the connection between the body and the mind. Breathing is the connection between life and death. Breathing is the link between consciousness and the subconscious (also known as the ‘storehouse consciousness’ or ‘Alaya-vijnana’ in Buddhism). Breathing is the connection between body and soul. Remember this.
Wise people focus first on their breath. Those who are mindful of their breath and practice conscious breathing are called meditation practitioners. Let me emphasize: conscious breathing means being aware of your breath. Everyone else still breathes (because otherwise they’d die), but they breathe automatically, like a machine.
Those who master meditation and can guide others are called Zen masters. However, the term Zen master refers to great masters of high-level meditation, such as Khương Tăng Hội, Vạn Hạnh, Thích Nhất Hạnh, Thích Thanh Từ, etc. (In English, they are known as Zen masters).
Those who teach meditation at lower levels (like myself) are called meditation teachers or Zen teachers in English.
Therefore, if you refuse to wake up during the ‘dần’ hour, you’re speeding up your journey to the grave.''
Additional explanation:
And indeed, between 3 and 5 AM is the lung detox period. This is why people with coughs often experience intense coughing at this time – as the detoxification process reaches the lungs. Hence, it's not advisable to take cough medicine, as it could hinder the body’s natural detox process. Also, sleeping too late and waking up too late disrupts the elimination of unnecessary chemicals from the body.

2. Don't let waste stay in your body past 7 AM
Advice:
''As mentioned earlier, between 5 and 7 AM is the time for the large intestine to detoxify, releasing waste in the form of stool. A healthy person must defecate during this time, without fail.
It's as if your body naturally demands you to go to the toilet at this hour, and if you only go once a day, it should be at the 'mão' hour. If you fail to go at this time, it's harmful to your large intestine and digestive system. And remember, you need to ensure you fully expel waste, keeping the large intestine clean (I'll write a separate article about this).
If you're still sleeping between 5 and 7 AM, waste is stuck in your intestines. Is this good? Stool is a toxin, which should be expelled from the body, but instead, due to your desire to sleep or your harmful habit of waking up late, your whole body has to deal with this waste.
Not to mention that when you defecate, you also naturally urinate, expelling urine from the bladder. And surely, no one believes that holding urine in the body is good.
So, if you continue to refuse to wake up early for a proper bowel and urinary movement, you're giving yourself a 'chance' to reach the grave earlier. Don't you care about your large intestine, bladder, and your precious body? Therefore, I recommend those who like to sleep late to wake up during the 'thìn' hour to expel waste, then go back to sleep.
While I give this advice, I know many won't listen, as they believe sleeping is more enjoyable and beneficial. People understand that if they don't breathe, they die; if they don't eat, they get hungry; and if they don't drink, they get thirsty, but they don't fear holding waste inside, even though it can harm the body. Sleeping late speeds up your journey to the grave.''
Additional explanation:
In summary, we should maintain the habit of going to the toilet from 5 to 7 AM because after waking up, the pressure in the rectum is higher than that in the anus, and both the internal and external anal sphincters relax. This daily morning defecation habit is very beneficial to health, as it helps the body expel toxins and creates a sense of comfort for the day ahead.

3. To live long, you must definitely eat breakfast
Advice:
''The upcoming time is the dragon hour, from 7 to 9 AM. This is the time when your stomach is active. If you don't have breakfast before 7 AM, what happens to your stomach? It squeezes an empty stomach, right?
The stomach secretes substances to digest food, but without food, is it good or bad for the stomach and your overall health?
Here’s something you might not know: your stomach contains a lot of acid, and its acidity level is similar to that of lemon juice. If you’re used to not eating breakfast or skipping it during this time, the risk of stomach diseases increases significantly.
What you might not realize is that the digestive system is our second brain, with the stomach being the heart of the brain. If the stomach doesn’t digest food, it affects many other organs in a chain reaction, from the small intestine to the large intestine, liver, kidneys, spleen, gallbladder, heart, and lungs... The whole body feels the impact.
So, if you know someone who stays up late, even on days off, and doesn’t wake up until after 7 AM, encourage them to read this.
For those who are used to waking up late or are too lazy or unwilling to have breakfast, I say this: YOU MUST HAVE BREAKFAST. If you can’t eat before 7 AM, it’s better to have breakfast before 9 AM than not to eat at all. Otherwise, the road to the grave gets a lot closer.
Additional Explanation
It’s important to emphasize that after a long night of sleep, your body will be severely lacking in energy. Meanwhile, morning is the time when we are most active, requiring our bodies to replenish nutrients. Therefore, breakfast is absolutely necessary to give our bodies the energy needed for a full day. We should eat before 7 AM because between 7 and 9 AM, the stomach is most active, and the small intestine absorbs nutrients at its peak. For those with a history of stomach issues, skipping breakfast can make the condition worse. The digestive fluids increase without food to mix with, which leads to attacks on previous ulcers, resulting in frequent pain.

4. Working relentlessly from 9 PM to 11 PM is detrimental to the Triple Burner
Advice:
''Let me explain about the 'Tuât' hour, which is from 9 PM to 11 PM. This is the time of the 'Tam Tieu' (Three Burners).
Many people are unaware of what 'Tam Tieu' is and how crucial it is. To make it simple: 'Tam Tieu' refers to the three hollow spaces in the human body: the Upper Burner, the Middle Burner, and the Lower Burner.
The Upper Burner is the uppermost cavity, from the mouth to the cardiac region of the stomach, containing the heart and lungs. The Middle Burner is the space in the middle, from the cardiac region of the stomach to the pylorus, containing the spleen and stomach. The Lower Burner is the lowest cavity, from the pylorus to the anus, containing the liver and kidneys. Now, do you see how important 'Tam Tieu' is?
Moreover, the function of 'Tam Tieu' is to convert food into energy, which means it turns substances in the body into vapor. This vapor then changes into another substance within the body. These are the biochemical reactions occurring inside.
You may have heard that the Upper Burner is like mist, the Middle Burner like bubbling water, and the Lower Burner like flowing water. You've heard this before, right? But now you understand it properly, don't you?
Are you surprised to hear that 'Tam Tieu' is essentially a home to live in, a wallet to keep money, a basket for shopping, or clothing to wear?
If you're surprised, that's great. It's a wake-up call. A wake-up call to change your thinking, to break bad habits, and to focus on nurturing 'Tam Tieu'.
Also, it is well known by those who read that in the Upper Burner, the lungs manage breathing, distributing air and nutrients into the bloodstream and throughout the body.
In the Middle Burner, the spleen processes and absorbs the essence of food and water, sending it to the lungs. In the Lower Burner, refined substances are stored in the kidneys, and waste is expelled via defecation and urination.
The energy of the Lower Burner flows downward, not taking in more. Furthermore, 'Tam Tieu' also plays a role in protecting the internal organs. Now, do you understand?
Yet, some people still work tirelessly during the time when 'Tam Tieu' needs rest, from 9 to 11 PM. I’m talking about those who intentionally harm their health, excluding those who have to work night shifts due to their job.
You are the one who does this intentionally. Violating this rule on purpose is far worse than doing so accidentally. If we are not required to work during 'Tuât' hour but still force our bodies and minds to work, the consequences can be severe.
Even negative thoughts, watching harmful movies, or reading unhelpful news, overburdening the senses... are detrimental to 'Tam Tieu'. It's best to rest at this time.
The wise meditate during the 'Tuât' hour. Some people live well by listening to calming music, drinking tea, relaxing, enjoying the moonlight and fresh breeze, and appreciating the sound of the wind.
They do everything possible to ensure 'Tam Tieu' rests and rejuvenates as much as possible. If you exploit your body and mind during 'Tam Tieu', you are hastening your own downfall.
As I mentioned earlier, I sleep during the 'Tam Tieu' time. I usually meditate from 9 to 10 PM and then sleep. It is extremely beneficial for health. It makes us strong, clear-minded, and peaceful. Truly amazing. Try it for a week, and you'll immediately notice the difference.''
Additional Explanation
Furthermore, working past 9 PM can lead to anxiety, agitation, or mental exhaustion. In a 2014 study, individuals who used smartphones late at night reported feeling tired, unable to sleep, and having difficulty concentrating the following day.

5. Why Do People Often Die at 3 AM? Save Your Liver
Lời khuyên:
''Từ 23 giờ đêm đến 1 giờ sáng là giờ của mật. Giờ này mật tiết chất độc ra. Bạn cảm nhận được ngay mà. Bởi miệng đắng. Buổi sáng ngủ dậy, bạn thấy miệng đắng là do mật tiết ra chất độc vào giờ tý đấy nhé.
Xin nhắc lại, theo đông y thì 23 giờ là bắt đầu ngày mới. Ngoài chuyện mật thải độc ra, nếu tại thời điểm ngày mới mà bạn không ngủ, không nghỉ ngơi thì rất có hại cho cơ thể. Hại nhất là mật. Mà mật liên quan chặt chẽ đến gan.Vậy nên, nếu không muốn đến nghĩa địa sớm, xin đừng thức đến tận giờ tý. Cơ thể bạn, bao gồm cả thân và tâm, không thích bạn đưa họ đến nghĩa địa sớm đâu nhé.
Cuối cùng tôi muốn bàn đến khung giờ sửu, tức từ 1 đến 3 giờ sáng. Đây là giờ của gan. Cũng xin nói luôn rằng có rất nhiều người chết vào giờ này.
Nguyên nhân là do gan có đến 64 chức năng. Khi mà gan yếu, các chức năng này không hoạt động được nữa thì ta chết. Nếu có người nhà bị bệnh nặng, khi thức đêm chăm bệnh nhân, nên lưu ý khung giờ này.
Nếu 1 giờ sáng mà bạn vẫn không ngủ thì rất hại gan. Giờ này gan thải độc. Giờ này gan đang cần bạn nghỉ ngơi nhất, cần bạn ngủ thật sâu nhất. Ấy vậy mà có người lại dại dột đi chống lại gan, làm tổn thương gan. Thật chẳng có cái dại nào dại hơn cái dại này. Rất thương!
Tôi muốn nhấn mạnh đến 1 ý rằng gan và mật hỗ trợ lẫn nhau, gắn kết chặt chẽ với nhau như một. 23 giờ là lúc kinh mạch của túi mật được mở ra. Nếu bạn chưa hoặc không ngủ thì sẽ làm tổn hại lớn tới đảm khí.
Tại sao ư? Bởi tất cả 11 cơ quan bao gồm lục (tức 6) phủ và ngũ (tức 5) tạng đều phụ thuộc vào túi mật. Nếu đảm khí hư, hỏng, yếu, thiếu sẽ dẫn tới việc giảm chức năng của tất cả các bộ phận trong cơ thể. Hơn thế nữa, khả năng miễn dịch giảm xuống.
Nguy hiểm hơn nữa còn ở chỗ nếu đảm khí bị tổn thương (do đảm khí hỗ trợ trung khu thần kinh) thì quý vị có nguy cơ rất cao mắc các bệnh về thần kinh. Đó là lý do tại sao những người mất ngủ triền miên dễ bị các triệu chứng hay bệnh như uất ức, tâm thần phân liệt, bồn chồn, ám ảnh,…
Từ 1 đến 3 giờ sáng cần ngủ rất ngon, rất sâu. Bạn nên nhớ nằm lòng rằng đây là thời gian kinh mạch của gan vượng nhất. Lúc này gan thải độc, sản xuất ra lượng máu mới.
Nếu bạn chưa ngủ hay không ngủ, có nguy cơ bạn sẽ có sắc mặt xanh xao, dần dần có thể sẽ mắc các bệnh về gan. Thức khuya vào giờ sửu, bạn rất có nguy cơ bị bệnh viêm gan siêu vi B.
Nguyên nhân rất dễ hiểu, là do cơ thể quá suy nhược, thậm chí bị rối loạn và virus cứ thể mà tấn công, xâm nhập vào cơ thể. Cơ thể yếu quá, bó tay, virus vào tự do, vô tư, thoải mái.
Và bạn cũng giúp tôi ghi tâm khắc cốt rằng tim chủ huyết mạch, tức là làm cho huyết dịch vận hành trong các mạch máu để dinh dưỡng và tư nhuận. Còn gan có chức năng lưu giữ và điều tiết máu.
Vậy nên nếu quá 23 giờ sáng mà không đi ngủ sẽ làm can huyết bất túc dẫn tới tình trạng tim không cung cấp đủ máu. Khi đó tim sẽ đập mạnh, loạn nhịp, run sợ, có thể dẫn đến cao huyết áp, xuất huyết não và nhiều bệnh nguy hiểm khác.
Đấy, ngủ đúng giờ là tối quan trọng. Ngủ đúng giờ còn quan trọng hơn cả ngủ đủ giờ. Nếu ban ngày bạn ngủ suốt cả ngày, dù có ngủ từ 8 giờ sáng đến 8 giờ tối cũng thua ngủ sâu vài tiếng lúc cần, tức quãng thời gian cho mật và gan.''
Giải thích thêm
Đối với gan, khoảng thời gian từ 1h đến 3h sáng là lúc gan hoạt động mạnh nhất để có thể bài tiết các chất độc hại, vì thế trong khoảng thời gian này càng ngủ sâu thì càng có tác dụng giúp gan hoàn thành việc loại trừ các độc tố trong cơ thể. Vậy nên, việc thường xuyên đi ngủ muộn sẽ ảnh hưởng không tốt đến quá trình bài tiết này của gan và dẫn đến những hậu quả xấu về sức khỏe.

6. Ngủ sâu 4 tiếng: Bí quyết vàng
Advice:
''Based on my personal knowledge and experience, we need to sleep deeply for at least 4 hours, from 11 PM to 3 AM. If you wish to extend your sleep to 6 hours, you should go to bed by 9 PM. For a full 8-hour sleep, you can wake up around 4:30 AM or close to 5 AM.
Some people are determined to sleep as early as 9 PM, or even earlier. Those who live longer often reside in high mountain areas. The air there is very fresh due to abundant trees, minimal traffic, and few factories. Additionally, they sleep early because they are not distracted by modern devices or the 'night owl' lifestyle common in cities.
Furthermore, you might not believe it, but many families and individuals go to sleep as early as 8 PM, which is the time of the fetus, the time of the heart. It's truly wonderful.
Why do some people live healthily to 100 years old? What’s their secret? Let me remind you, they live healthy well into their centenarian years, not just barely surviving in sickness and suffering.
My grandmother lived in Dong Hoa commune, a suburb of Thai Binh city, and she stayed healthy until she was 93. Before she passed, she was still strong and sharp.
What I remember most is when the village head, Ha Van Tang, mentioned the several roles my grandmother held – she was a member of the Dong Hoa agricultural cooperative, a member of the elderly association, and a member of the Phu Sa temple.
That’s all. Yet, she lived healthily until her passing. There were many reasons (and I may write separately on this), but we can’t overlook that she always woke up early throughout her life. Waking up early is a great habit both my grandparents kept for many years. Thankfully, I inherited this good habit.''
Additional Explanation
At night, we should go to bed between 10 – 11 PM. Our sleep tends to be the deepest between midnight and 3 AM. Therefore, it is crucial to allow at least 1 hour to fall asleep soundly at night. This means that skipping this golden sleep window could lead to health problems, as the body’s natural rhythm is disrupted. During this time, you can relax by talking to someone, listening to music, or a radio program before bed to help your mind unwind and ensure a better, deeper sleep.

7. The Solution for Night Shifters
Advice:
''Finally, I want to address those who, due to the nature of their work, have to work late or on night shifts. With the right approach, they can still improve their situation. This is similar to how food can be 'yin' and we can transform it into 'yang.' There is always a solution to every problem.
For these individuals, the key is to keep their work as light as possible. But more importantly, they need to learn and practice mindfulness. Mindfulness is absolutely crucial.
The English term for mindfulness is 'mindfulness.' It is now being incorporated into many organizations, schools, and businesses in developed countries around the world. Many mindfulness centers have been established in the US and other countries. Some courses can even cost thousands of dollars.
I've been invited to guide people overseas on living and working with mindfulness. One fascinating aspect of Westerners is that when they discover something useful, scientific, and practical, they quickly adopt and apply it thoroughly with great determination. It’s quite impressive. And when they invite someone, they often look for experts, individuals with deep research and practical experience in the field.
I also hope that our local government, particularly the Ministry of Health, other agencies, schools, hospitals, and businesses, will take mindfulness seriously. At the very least, you can read the famous and brief book 'Cancer Treatment Through Mindfulness' by Phap Dang.
The author himself was diagnosed with cancer, but he successfully treated himself through mindfulness. It’s quite miraculous.''
Additional Explanation
Most people already know that working night shifts can have various impacts on health. Therefore, getting proper sleep after a shift is incredibly important. In addition to the advice provided, we can also compensate by scheduling sleep after the shift appropriately. For example, you should aim for 5-6 hours of sleep in the morning after the shift and 2 hours before starting your next shift. Along with this, proper nutrition, meal timings, and organizing night shift work schedules can all help maintain optimal health.

8. I never go to bed after 11 PM
Advice
''You and I - the one reading these words right now - live entirely opposite schedules. While you're awake, I'm asleep, and while you're asleep, I'm awake.
Right now, as I'm writing these words, I’ve been awake for about two hours.
As I’ve written (and lectured many times), "The key to a day is in the early morning hours", meaning the most precious time of a day is the early morning hours, from 3 to 5 AM.
I usually wake up during this time to take deep breaths, meditate, do yoga, and practice Qi Gong. I sit down to write my articles and check my email, often posting my first updates on Facebook by around 5:30 AM.
Right now, specifically, it’s 5:13 AM. I finish writing and send my work by about 6 AM.
I have breakfast before 7 AM, usually around 6:30. Before eating, after sending my articles and checking emails, I spend about 30 minutes reading.
Because I remember the words of Will Rogers: there are two ways to learn. One is by reading, and the other is by being around people smarter than you. The English version is "A man only learns in two ways, one by reading, and the other by association with smarter people".
I do all this so that by around 7 AM, I can be at work, teaching, or attending scheduled meetings.
Likewise, I go to bed at 10 PM (sometimes at 9 PM). I never go to bed after 11 PM, except for emergencies or special circumstances. However, most people stay awake past 9 or 10 PM. Some even go to bed after 11 PM.
There are a few individuals who seem to "destroy their health" or what I call those who "invite illness into their lives", or those who seem to want to "arrive at the cemetery sooner" by staying up late after 11 PM, even well into the early morning hours when a new day begins.
You and I have opposite sleep schedules, even reversed. This means one of us is being unreasonable. Please don’t jump to conclusions or judge just yet, try to read the entire article first.
I must also clarify that this article isn’t solely based on my research through reading and studying hundreds of books in various languages, including English, Russian, French, Chinese, and Vietnamese… but on what I have practiced for many years.This is my personal experience. Let me emphasize again, this is real experience. It’s my habit. So when you read it, you might find some things completely new or even shocking, while other parts may seem familiar, perhaps from a book you’ve read before.
That’s fine. And once again, let me remind you, I’m only sharing my real experiences, things I’ve witnessed, and practices I’ve tested on my own body. Don’t trust me immediately, read carefully, even read several times. And if it feels reasonable, apply it. The most practical proof of this is the tangible results you’ll see after applying it for a short time."
Clearly, Dr. Nguyễn Mạnh Hùng’s advice is: we should go to sleep before 11 PM.

9. Did you know that a new day starts at 11 PM?
Advice
''Some people, lacking knowledge, believe that a new day begins when they wake up. Others think it begins at sunrise, while some say it starts at 5 AM or 3 AM. All of these ideas are incorrect!
Scientists, however, are very precise, stating that the new day begins at midnight, or 12 AM, or 00:00 hours. But even this isn’t entirely accurate!
Today, I’m sharing the truth with you: a new day actually starts at 11 PM. Yes, the new day begins a full 60 minutes before midnight. Let me explain further.''
Further Explanation
According to scientists, the evening is the time when the immune system expels toxins and recovers. From 9 PM onwards, the human body begins to need relaxation to easily fall asleep. About 1-2 hours later, the body can enter a deep sleep, which helps the biological clock function smoothly, allowing the immune system to work effectively. If you stay up too late, you increase your risk of illnesses such as obesity, memory loss, blurry vision, hearing loss, premature aging, heart disease, diabetes, and more. It is best to sleep before 11 PM to ensure that your body rests and recovers properly.

10. It's important to remember the specific times for each part of your body
Advice:
''You are probably well aware (except for those who are too lazy to read or haven't acquired basic knowledge about the body and health) that the body consists of six viscera and five organs.
However, what you may not know is the exact time when each part of the body functions. Let me share this information first, as it is intricately linked to your sleeping schedule and overall lifestyle for better health.
From 3 to 5 AM is the hour of the tiger. This is the time for the lungs. From 5 to 7 AM is the hour of the rabbit, the time for the large intestine (also called the colon).From 7 to 9 AM is the hour of the dragon, the time for the stomach (also called the gastric). From 9 to 11 AM is the hour of the snake, the time for the spleen (also called the pancreas).From 11 AM to 1 PM is the hour of the horse, the time for the heart (also called the cardiac). From 1 to 3 PM is the hour of the sheep, the time for the small intestine (also called the duodenum).From 3 to 5 PM is the hour of the monkey, the time for the bladder (also called the urinary bladder). From 5 to 7 PM is the hour of the rooster, the time for the kidneys.From 7 to 9 PM is the hour of the dog, the time for the pericardium (also called the heart covering). From 9 to 11 PM is the hour of the pig, the time for the triple burner. From 11 PM to 1 AM is the hour of the rat, the time for the gallbladder (also called the bile). From 1 to 3 AM is the hour of the ox, the time for the liver (also called the hepatic).''
Further Explanation
According to traditional Chinese medicine, the organs in the human body follow a continuous cycle every day. Providing the body with nutrients and energy, while eliminating waste naturally, keeps it healthy. However, when waste is not properly eliminated, it turns into toxins and harms health. Each organ has its own detoxification period. As a rule, we must pay the price for irregular habits that deviate from the natural rhythm of bodily functions. Therefore, to maintain a healthy body, we should consider setting up a daily schedule that aligns with the body's internal clock to achieve the highest effectiveness.
