Organ Clock

Although we as humanity increasingly tend towards new technologies and the digital world, we must not forget that, like everything else, we are part of nature. We live on a planet that is constantly influenced by the surrounding universe, as it orbits the Sun, how it rotates around its axis, and how the Moon orbits around it. Thanks to all this, we get to know day and night, different seasons, etc. Plants turn to the sun, wolves howl at the moon, bears go to sleep, leaves of deciduous trees fall and birds and salmon migrate. Similarly, the human body is subject to many rhythms – daily rhythm, lunar rhythm, hour rhythm, annual rhythm and rhythms with far longer periods. The Chinese, who have been studying natural phenomena and laws of nature for thousands of years, did not distinguish between the dynamics of nature and the dynamics of the human organism – the events in the outside world are also reflected within the living organism. One way in which Chinese medicine traditionally describes the course of energy depending on the daily cycle is organ clock. They represent maxima and minima of energy in a particular meridian over a 24-hour cycle.

In organ hours, the 24-hour cycle is divided into 12 parts after 2 hours. There are 6 pairs of organs, one organ of the pair is always yin (full) and one yang (hollow). One organ is assigned to every two hours. During the day cycle, the organ has the highest activity in its hour. 12 hours earlier or later, this body has the lowest activity. This is called the noon-midnight rule in Chinese medicine. We suspect that humanity in ancient times lived in greater intuition and feeling. The rhythm of the day was far more important to man than we understand today.

The organ clock is based on a system of Chinese astrology that works with 10 energies of celestial tribes (which correspond to the element of wood, fire, earth, metal and water) and 12 energies of earthly branches (which correspond to the energy of wind, heat, heat, moisture, dryness and cold) . They always go together in pairs and together they form the four pillars of time energy – the pillar of the year, the pillar of the moon, the pillar of the day and the pillar of the two-hour patrols.

By respecting the organ clock,for example, you will know when your brain is most active, at which hour you diget food the easiest, when it is best to go exercise or at what time effects of certain drugs will be increased (that’s why healers tell you when to take certain medications).

Here are the organ clocks themselves (and a more detailed description below):

From 11pm to 1am

Gallbladder starts working. Those who have trouble with this organ usually wake up or cannot sleep at this time. If you don’t sleep yet, try not to think too much.

From 1am to 3am

The liver is activated, thus causing the greatest detoxification of the organism. At this time, attenuation occurs (the lowest oxygenation of the brain). It is not recommended to drink alcohol, smoke, use fats or drink coffee.

From 3am to 5am

The lungs are in action, which are being cleaned at this time. At this time, smokers, asthmatics, those with sick bronchi, rhinitis and inflammation of the airways usually wake up. People who have a weaker psyche should make no serious decisions, right now they are most prone to fear and pessimism.

From 5am to 7am

The colon has the highest activity. If you wake up to the toilet at this time, it’s okay. Blood pressure increases and heart rate accelerates. The organism is awakening. It’s good to get used to getting up regularly at this time, even during the weekend. You will have much more energy all day long. It is good to drink a glass of lukewarm water with lemon.

From 7am to 9am

The stomach gets into action. It is very important to consume vitamins at this time. The body needs to be warm. Therefore, no cold shower or bath is suitable at this time. The human psyche is positive

From 9am to 11am

At this time, the pancreas and spleen are in operation, so do not use alcohol at all, which does not benefit them. It’s good to eat fruit, honey (it’s the only time of day when the body is able to digest sweets). Avoid excessive physical activity. We can perform high mental performances. Around 11 am, there is a morning performance peak.

From 11am to 1pm

The time of active heart activity. Lunch time, but definitely not overeating and certainly not coffee. There is a slight attenuation. A walk in the open air or a short sleep is recommended.

From 1pm to 3pm

The small intestine is now the most active, taking care of digestion, so forget about the next meal. The ideal time to go to the dentist because the sensitivity of the teeth is reduced at this time. Physical activity begins to increase.

From 3pm to 5pm

The bladder works the most. It’s good to drink herbal teas, do sports. The digestive system is capable of receiving hearty food. Organism handles physical stress – activity rises and reaches second performance peak.

From 5pm to 7pm

Kidneys are in action. It is very important to eliminate everything that harms them, fats, sugar, salt, lemonade, chemicals, coffee, alcohol, cold, stress. Drink heavily.

From 7pm to 9pm

The envelope of the heart (ie blood) comes into action. Memory is working at full speed, we are bright, the psyche is in harmony, so use it for relaxation, listening to music and mental development.

From 9pm to 11pm

The period of activity of the “three heaters” (connection of upper, middle and lower torso including all competent organs). It is a time when the body prepares for sleep. Do nothing to activate. Never smoke. Also skip food.

    This is an amazing article. It is the very first time I have encountered the organ clock and daily cycle.  I had no idea that the natural rhythm was that significant for our bodies.  These periods referred to as organ clock, if observed, I am now convinced that we could be much more healthy and very likely live a more fulfilled life and perhaps a longer life as well.

    The Chinese medicine appeared to be very much in tune with this natural rhythm.  Seems that our very early ancestors may have had this figured out as well.  Unfortunately with the advent of modern methods in farming, living in cities, and generally having much more busy life, we humans have fallen away from the more natural way of living and feeding our bodies at critical intervals.  

    Just a note here that I believe that processed foods are about the worse thing we can eat.  I am a firm believer in eating mostly raw fruit and vegetables and in eating fish over other forms of meat.  

    The organ clock is a fascinating article and thank you for publishing it.

      Hi Time, about the diet … that’s the right question, Chinese medicine is advising to consume mainly hot meals, that the body is like a stove in which it is necessary to continually throw fuel to “burn”. However, there are discussions that food is losing some of its beneficial effects through heat treatment. Either way, I don’t eat meat at all and I have a great experience with it … everyone can react differently, but for example (not only) digesting meat is very demanding.

    WOW! I had never realised that our bodies were so in-tune with our surrounding planet and I just thought that each bodily functions were working with the routine of each individual

    I personally have my own routine which I have kept for some time now so is your organ clock a general statement or is it the same for every single being on this earth?

    Fascinating article!  I had not heard of the organ clock before, but this ties in perfectly into some other research I was doing on what time of the day was best suited for certain activities.  It definitely makes sense to consider the organs and the natural rhythm of the body.  Thank you for this insight!  I’m going to keep experimenting with my schedule to be more productive and live a healthier, balanced life.  I’ll be giving this chart and the detailed info you’ve provided another look.

    Whao! Some of these ideology are related to my body function. For example, between 3 and 5a.m when the lung is at work, whenever i have cough or cattarh, it is that period they do affect me the most. That is what usually caused my sleeplessness at that our. Another one is colon regulation, I normally visit toilet between 5-7a.m, especially 6:00a.m. I think am growing love for astrology. Thanks for sharing.

    I am amazed to how accurate this organ clock is, as my mother frequents the toilet from 5am to 7am. She said, that morning habit is good as it helps her fine tune the day by eliminating wastes right in the morning. With that, I’m training myself to have that same morning habit for my own health.

    I just noticed something with this organ clock. It seems not all organs are involved here. What about the brain? I didn’t see brain in the clock.

      I suppose that it is due to complexity of brain functions. Organs in the organ clock function according to “cosmic time”, while the brain itself has its own function, through which it is able to perceive time … and that perception of time is not continuously the same, it is also subjective, so probably therefore. The brain is a control center for many processes, whereas the organs in the clock have a clear function that does not interfere with the psychological and chemical elements that happen in the brain.

    Thank you for the awesome and very informative website. I have never really thought about Chinese medicine. I absolutely love the organ clock that you put in there. As a nurse, I knew that some organs were more active at different times than others but it was great to find out the times that I should cut things out like coffee for example. I believe that the information you have provided is extremely helpful to me and to the rest of your readers.

    That was an amazing article. It sheds some light on why night shift workers feel so totally out of sync with the rest of the planet. I spent over 30 years rotating shifts month to month and to this day, after three years of retirement, still feel out of sync.
