There are no two individuals with the same biological clock, and each person has a different optimal learning time. Therefore, it is important to understand your "golden time" and plan your schedule accordingly to improve learning efficiency. The human body also has regular physiological fluctuations throughout the day.
1:00 AM
At this time, most people have already slept for 3-5 hours. It is the period of dreaming sleep, during which dreams are more frequent and people are more susceptible to pain. Some diseases may worsen at this time.
2:00 AM
The liver is still working and using this time to produce various substances needed by the body and eliminate harmful substances. Most organs in the body are in a state of slowed or stopped function, resting and recovering.
3:00 AM
The whole body is at rest and muscles are completely relaxed.
4:00 AM
Blood pressure, pulse, and respiration decrease at this time. Blood pressure is at its lowest, and blood supply to the brain is minimal. Muscles are in a weak circulation state, and respiration is still weak. This is a vulnerable period and the body organs are still functioning at a slowed pace. However, hearing is sensitive and can be easily awakened by minor noises.
5:00 AM
Kidney secretion decreases, body temperature rises, and the body has gone through 3-4 sleep cycles (non-dreaming and dreaming sleep cycles). If you wake up at this time, you can quickly enter a state of full energy. Therefore, 5-6 AM is the peak time of the body's biological clock.
6:00 AM
Blood pressure increases, heart rate accelerates, body temperature rises, and adrenal cortex secretion begins to increase. The body is fully awake and it is the best time for memory retention.
7:00 AM
Adrenal cortex secretion reaches its peak, body temperature rises, blood circulation accelerates, and immune function strengthens.
8:00 AM
The body has completed rest and enters an excited state. The liver has eliminated all toxins from the body. The brain has strong memory retention and it is the second best time for memory.
9:00 AM
Nervous excitability increases, memory remains optimal, infection rates decrease, and sensitivity to pain is reduced. The heart works at full capacity and energy is high.
10:00 AM
Enthusiasm increases and lasts until noon. It is the first peak time of the day and pain can be easily relieved. This is the best time for introverted individuals to analyze and create, and any work can be accomplished. It would be a waste to idle during this time.
11:00 AM
The heart continues to work rhythmically and maintains a positive mental state. At this time, the body does not easily feel tired and there is little work pressure.
12:00 PM
The body's energy is fully mobilized, and it is time to eat. Alcohol is still sensitive at this time. If you drink during lunch, it will greatly affect the afternoon's work.
1:00 PM
After lunch, there is a feeling of mental fatigue as the first phase of daytime excitement has passed. It is advisable to take a short nap of 30 minutes to 1 hour.
2:00 PM
Energy decreases and it is the second low point in the 24-hour cycle. Reaction time is slower.
3:00 PM
The body's functions start to improve, and sensory organs are particularly sensitive. The body enters a normal state, work capacity gradually recovers, and it is the most productive time for extroverted individuals, lasting for several hours.
4:00 PM
Blood sugar increases but quickly decreases. Doctors call this process "postprandial hyperglycemia."
5:00 PM
Work efficiency is higher. The sense of smell and taste are at their most sensitive, and hearing reaches its second peak of the day. Exercising at this time has better effects than in the morning.
6:00 PM
Physical activity and endurance reach their peak, and the desire for increased exercise rises. Pain sensitivity decreases, and athletes should train harder at this time to achieve good results.
7:00 PM
Blood pressure rises, psychological stability reaches its lowest point, and mental instability increases. Small matters can easily cause disputes.
8:00 PM
The body has already stored enough food and water for the day, and rest is most important. Reaction time is exceptionally quick, and drivers are in their best state, less prone to accidents.
9:00 PM
Memory retention is particularly good, and it is the best time for memory until just before sleep (the fourth and most efficient time).
10:00 PM
Energy levels start to decrease, drowsiness sets in, immune function strengthens, white blood cells increase in the blood, breathing and heartbeat decrease, and adrenal cortex secretion decreases. At this time, most organ functions are at their lowest point.
11:00 PM
The body prepares for rest, and cell repair work begins.
12:00 AM
The body starts its most demanding work, replacing dead cells and producing new cells to prepare for the next day.
Based on this information, you can plan your study schedule rationally. Remember, there are no two individuals with the same biological clock, and each person has a different optimal learning time. Therefore, it is important to understand and utilize your own "golden time" to improve learning efficiency.
