Formation of Inner Time

Time is lived together with two different perceptions of time. First, time is perceived in its true form and without error. Such is the biological and internal clock. Here, time is smooth and standardized so that it flows with time. In the second, the perception of time is impaired. Time never passes, or more often, it flows like water. Can’t keep up with the pace…

1-Biological Clock

The biological clock is our daily routine. It is the body’s natural response to the world, to every event and person encountered, according to certain times of the day. Such as the secretion of hormones that make us sleepy in the evening, the feeling of hunger when our stomach is empty… In recent years, it has been revealed that many diseases that people experience are caused by behaving inappropriately to their daily biological rhythms.

This is not just for humans. Mairan placed the mimosas in a dark room. However, the leaves of the plant invariably continued to open in the morning and close again in the evening. In 1929, at the talks at the Paris Academy of Sciences, he talked about his experiments. He made a bold conclusion in his publication: “The plant’s activity depends on the bed it is connected with that sensitive sense that allows a patient to feel the difference between day and night.” In his time, hospital rooms were dark” (Klein, 2006).

The biological clock is found even in simple single-celled animals such as the euglena. This little creature has lived on earth for over a billion years. Just like the mimosa, it does its usual movement in pitch darkness (Klein, 2006, Palmer, 2002). Öglena produces the rhythm of her simple life herself. Indeed, there is a biological clock inside this tiny organism (Klein, 2006).

2-Internal Clock

Our internal clock, which is like a biological clock, but becomes specific by being specific to the cells rather than being directed to the whole body, works with a great performance. “There are 100 billion cells in the human body, each up to about one noon. As incredible as it may sound, each cell has its own internal clock.

This timepiece works according to the hourglass principle. Genes called “clock” (hour) and “per” (short for “period”) enable the cell to produce proteins. But when the amount of these proteins rises above a certain threshold, the genes are blocked. The chamber of the watch is full, the mechanism stops. Now the hourglass will be reversed and the cell will be emptied: Proteins are in the process of being broken down. After a while the game restarts. Re-production is underway. Such a cycle takes exactly 14 hours and a few minutes” (Klein, 2006).

Molecular biology owes its knowledge that such a clock works inside every cell to its favorite experimental animal, the fruit fly (Klein, 2006, Young, 2000, Dunlap, 1999, Young, 1998).

Before long, biologists discovered clocks in all possible cells of mammals—even in their eyes, lungs, and even bone-forming cells (Klein, 2006, Dunlap, Loros, and De Coursey 2004). There is only one explanation for this: A timing mechanism is hidden in each cell. Since fly and human cells have basically the same structure, humans also contain billions of hours (Klein, 2006).

Indeed, some organs regulate their own functioning (Klein, 2006, Yoo et al., 2004). For example, the liver even has sensors that enable it to exchange information about time with other organs (Klein, 2006, Zulley and Knab 2000). The American chronobiologist Jay Dunlap likens the human body to a gigantic watchmaker’s shop, where the tick-tock of some clocks can be clearly heard, while others work silently (Klein, 2006).

Because genes regulate the internal clock, this personality trait is inherited. Sleep researchers have discovered variations of certain clock genes associated with being more awake in the morning (Klein, 2006; Archer 2003, Katzenberg 1998).

3-The Importance of Light

Light energy is the most important energy in the world. Sunlight regulates the biorhythm and the internal clock. If the sun did not have lights and the earth remained in darkness, there would be no life. Light, which is an indispensable part of life; It is very necessary for the human body to lead a healthy life. A very popular Turkish proverb on this subject is known by everyone. “A doctor enters the house where there is no light”.

When the summer months come, almost everyone knows how people who are overwhelmed by the dark and closed air of the winter months and become depressed are relieved by the shine of the sun. As a matter of fact, ‘light therapy’ among complementary treatment methods has become extremely popular in countries with mostly closed air in recent years.

“All creatures use the sun to set their chronometers. Even the boy has only one eye for this. Not to see. This single-celled “eye animal” senses the light and detects where it is above, but primarily the change of day and night. Because his biological clock is also a little wrong (unlike mammals, it goes 20 minutes faster) (Feldman, 1967, Klein, 2006). However, when morning comes again, the clock in the cell is set to the correct time. This adjustment takes place in the form of light signals activating the message-giving substances and these substances slowing down the reactions inside the cell and thus the flow of the chemical hourglass (Klein, 2006, See B. Roenneberg and Merrow 2003).

It is no coincidence that in humans the central clock is located at the intersection of the two optic nerves coming from the eye. Thus, when the morning light falls on the eyelids, it is reported across the optic nerve. While you are still in the final stages of sleep, special sensors in the eye become particularly sensitive to light (Klein, 2006).
