What is Biological Clock?
How It Works?
By Dr. Jack Hsu, (6/1/2013)
Our biological clock controls our daily circadian rhythms to conduct our body’s daily activities, such as when to wake, to sleep, to eat, to drink, to release liquid or solid wastes from out body, to conduct functions of organs in our body, such as body temperature, blood circulation, heat beats, physical energy, mood, memory, woman’s period cycle, producing hormones, enzymes, metabolisms, detoxing cycle, etc. Our biological clock is also known as clock genes, is controlled by suprachiasmatic nucleus (SCN) of brain hypothalamus. The SCN is responsible for controlling circadian rhythms. The neuronal and hormonal activities it generates regulate many different body functions in a 24-hour cycle.
Disruption of the biological clock has tremendous effects on our body health and causes many kinds of diseases such as disordered metabolic diseases (e.g. obesity, diabetes and insulin resistance..), aging acceleration, etc. and even jeopardize our life.
The organs in our body like heart, liver, pancreas and the intestines, etc. all have their own circadian rhythms. Each organ produces hormones, enzymes and other molecules at various times of the day. Our brain conducts coordination the functions of the various organs.
Metabolic disorders occur when the brain is not in sync with the related organs. For example, when the pancreas is out of sync with the liver and the brain, the insulin production will be too high or too low. Studies have shown that people who work at night and sleep during the day are at increased risk for diseases like diabetes, metabolic syndrome and obesity.
As we learn more about the importance of our body biological clock to body health, it becomes clear that a normal sleep-wake cycle is vital for normal functioning of our body organs to maintain at healthy conditions.
There are many important organs in our body:
- Heart, liver, spleen, lung, and kidney: These organs’ major functions are for storage, like liver for blood, lung for air, kidney for secretion liquid etc.
- Stomach, gall bladder, small intestine, large intestine, triple warmer, pancreas and bladder: These are digestion and excretion system.
How do these organs work? Dr. Huang (Reference) summarized the information about the biological clock and is shown below:
The green ribbon area shown means the best time for your body to relax, detox, clean, and recover, etc. So, it is strongly recommended to rest and sleep during this period, let your internal doctor has enough time to do repair, and maintenance work. As mentioned before, you may test yourself to verify how important the biological clock is: check yourself how you feel:
- Case 1: Sleep at 11 pm till 7 am next day, and
- Case 2: Sleep at midnight 3 am till 11 am the same day.
The sleeping time for both cases is 8 hours. Case 1 is the healthy way for rest. You should feel energized when you wake up from the case 1 practice, and ready to work! However, the second case you should feel still drowsy and tired! If you sleep after 3 am quite often, and your liver does not have enough time to do its job like detoxing, and the related metabolisms, etc. Your liver eventually will be damaged and shows symptoms of liver diseases.
The other example is “jet lag” effect. If you travel from USA to China, there are 13~14 hours difference. It is almost reverse day-night time cycle. You should feel very discomfort in the first week. And your biological clock needs about a few days to even a few weeks depending upon your age to be adjusted.
If you work too hard, eat too many fast foods, drink a little water daily, and not follow the biological clock to release excrements in time, or you have constipation problems, then you have good chance to get colon cancer! Normally, we have bowel movement in the morning every day to release excrements! At least once daily is required for your large intestine to eliminate the solid wastes, two times is better. But not more than 3 times daily. If your fart smells stink, it is possible because your bowel movement and elimination of solid wastes is not following your biological clock!
To keep you healthy, you have to follow your biological clock to do your work and rest! Rest is for your internal doctor to do its job to repair and recover your body to the good normal conditions, and ready for next day! If you mess up your body’s biological clock, you will have some kind of diseases occur soon and later. Keep in mind, rest is prepared for a longer life to go. So, work hard, but rest on time as well, no matter what! Your body health is the most important job for you to do in your whole life, not your projects, not your wealth, not your reputation, because if your body is gone, your everything is gone as well.
The daily circadian rhythms are (military clock):
- 07~09: Adrenal cortex hormone secretion reaches high point, so, it is time for high risk of strokes, or heart attack; Body temperature is increased slightly; Blood circulation is accelerated; The immune system is enhanced; Liver has completed detoxing job; Brain memory is strong in this period; Time for Breakfast.
Note: when you wake up following the following 3 step before standing up to avoid heart attack:
- Keep lying on the bed for at least 1 minute;
- Sit on the bed for at least 1 minute, and drink a cup of warm water;
- Stand up and move slowly to start daily work.
- 09~11: Spleen converts foods to blood, energy and different of secretion liquid required by body, and also produces red blood cells; heart is working in full power; body is energized and excited; good memory; The best time for work!
- 11~13: Heart is still fully working; Positive mood; The body is at the highest energy situation, tick a signal for lunch to recharge. Because blood pressure and heart beats are high in this period, so do not drink alcohol.
- 13~15: After lunch, feel drowsy and tired, need a nap (0.5 ~ 1 hour); Energy is decreasing, and reaction is slow. Small intestine absorbs nutrition, and separate solid and liquid wastes.
- 15~17: Energy is restored. Blood sugar is increasing; Bladder stores wasted liquid and releases body heat.
- 17~19: High work efficiency; good time for exercises; more sensitive in smell and taste; Kidney starts to store nutrition absorbed.
- 19~21: Blood pressure is increasing; unstable emotion in the hour of 19; fully store food, and water, the heaviest weight in a day; rapid response reaction; Good mood; Pericardium cleans pathogens around the heart.
- 21~23: Good memory; body temperature is decreasing slightly; feel sleepy; function of the immune system is enhanced; white blood cells are increasing; breathing and heart beats slows down; hormone secretion is decreasing, etc.
- 23~01: Body needs to rest; cell repair work starts; produce new cells for replacement; Gall bladder released bile to aid fat digestion; PSNS starts to work; Marrow produces blood cells; Start sleep.
- 01~03: Liver starts detoxing; producing enzymes; hormones; metabolism; blood cells, etc. Sensitive to pain; Most of organs are in rest or recovery mode.
- 03~05: Deep sleep situation; Body is fully relax and rest; low blood pressure; heart beats, and breathing frequency, so easy to pass away in this period; Sensitive in hearing. Lung help body detox.
- 05~07: Less secretion from kidney; the body is fully recharged; Blood pressure and heart beats is increasing; Bod temperature is increasing; Adrenal cortex hormone secretion is increasing; The body is under awaking mode; good memory; Large intestine absorbs water & some nutrients from wastes; Time to eliminate solid wastes stored.
Studies show that the cell production rate during 23 ~ 05 is about 8 times of day time. So, the absorption rate to skin products like nourishing night cream and moisturizers is high. This is the best time to maintain and to recover skin more effectively.
I believe researchers can find the best time of day according to the biological clock for weight loss and blood sugar control.
