Biological clock and human health.

The “biological clock” regulates in every organism some very important and necessary vital functions, such as the wakefulness cycle of sleep, hormone secretion, blood pressure, and even metabolism!

The science dealing with the pineal gland and the pituitary gland is called chronology and is based on the study of biological rhythms.

The biological or circadian rhythm is the daily cycle that follows every organism and is characterized by a rhythmic alternation in the levels and balance of chemical components in the body and the conditioning of biological functions.

Although these rhythms are exclusively autologous, with many biochemical pathways involved in their regulation, they are directly influenced by the great adaptability they present through various external factors such as heat and daylight!

These discoveries were granted because they provided the necessary explanations for how each organism managed to adapt its biological rhythm in a way that coincides with the Earth’s rotation.

This was achieved by isolating the gene that controls biological rhythm, thus showing how this gene is responsible for encoding a protein that is present in cells overnight and degraded during the day.

The circadian rhythms are affected over time by behavioral patterns and external stimuli.

The main activities associated with the biological clock that are able to keep it organized or gradually ignore it are as follows:

▪️ Sleep is regulated by the biological clock, with light being the main external stimulus that keeps it steady.

▪️ Food is the main catalyst for synchronizing circadian rhythms to the peripheral tissues of the body.

▪️ Metabolism is directly related to circadian rhythm and food intake, as it is the only person responsible for planning energy production that is similar to activities that everyone is expected to meet during the day.

▪️ The immune response is most effective during wakefulness, as the body’s needs increase.

▪️ Aging does not regulate circadian rhythms.This causes the elderly to have difficulties with basic daily activities, such as sleep, energy production, etc.

▪️ Transatlantic and intercontinental flights cause physical and mental exhaustion, as well as disruption of circadian rhythms.

▪️ The cell cycle and cell differentiation appear to be controlled by circadian rhythms, without any method being revealed.

_ Scientific data.

The center of the biological functions of the human body is located in the upper hypothalamus of the brain called the hyperboloid nucleus.

For many years, it was seen as the only clock made of neurons that respond to wake behaviors and regular feeding during sleep. This central clock is involved in directing basic physiological processes throughout the body.

Researchers have discovered that every cell, including microbes, has a standalone clock and is fully functional.

More specifically, each tissue and every organ appears to have unique daily cycles, responsible for specific biological functions but also for the unique metabolic functions of each organ.

Thus, we can ensure that every individual cell in the body consists of a basic genetic clock, as a nucleus, and then there is a wide range of distinct auxiliary rhythms with the genetic cycles responsible for synchronizing the metabolism as well as for its behavior for each cell, tissue and organ.

Changes in the biological clock affect the physiology of the human body. Human cells consist of a large number of genes and operate in a 24-hour cycle. It is one of the largest groups of genetic networks influencing the most important functions of physiology.

These networks are mainly affected by:

1. Exposure to daylight and night darkness.

2. Hours of eating and sleeping.

Each change in biological rhythm affects communication between cells and tissues, leading to their progressive release from controls.

Genetic and epigenetic networks produce specific times to perform certain functions that are difficult or impossible to do simultaneously. These circadian rhythms circuits improve energy production and use for any necessary activity.

Indeed, disruption of these processes can lead to many metabolic diseases, such as:

1. diabetic.

2. Hyperlipidemia.

3. Obesity.

4. Thyroid disorders.

5. Osteoporosis.

For example, recent research has shown that strict diet and fasting hours can positively influence abnormal rhythms to treat even chronic diseases!

The variables that interact with the circadian control centers are related to energy balance, nutrition, fasting, as well as light and darkness. These variables include temperature as well as physical activity.

Perhaps the most researched variable is a special diet called a fixed diet (i.e. eating at the same time every day). This has interactions with energy balance cycles that include absorption, storage, and utilization of molecules.

Summary of the daily hours of human metabolism:

Early in the morning.

1) Melatonin production stops.

2) High blood pressure.

3) Bowel movement is stimulated.

4) Increases testosterone.

afternoon.

1) There is a faster reaction time.

2) Better cardiovascular performance.

3) Increase muscle strength.

In the evening .

1) High blood pressure.

2) Increased body temperature.

night.

1) suppress bowel movements.

2) The secretion of melatonin, which regulates the sleep cycle, causing drowsiness.
