Why is important to coordinate with the cycles of day and night by Andreas Moritz

Although not obvious, the human body is largely regulated by biological rhythms. All organs, systems, and cells are controlled by precise circular patterns of rest and activity, which can well be said to reflect universal laws.

Each biological timer dictates a specific rhythm or cyclical behavior in a group of cells, an organ, or an endocrine gland. The various timers of the body are perfectly coordinated with a central clock. The central clock coordinates the timers and ensures that all the activities of the organization are performed smoothly, according to a prescribed schedule. And this program is based on the constant efforts of the body to maintain its balance. The central clock of the organism is regulated by the most basic circular rhythm of nature, which is known as the circadian rhythm.

The circadian rhythm urges us to be active in the morning and to relax in the afternoon. The rotation of the earth around its axis and the sun create the exact cycles of day and night as well as seasonal changes. These rhythmic, repetitive patterns of nature, program our DNA to perform all bodily activities with absolute precision and impeccable coordination.

All external events that take place in the physical world are associated with similar events within our body. For example, the sunrise triggers a corresponding sunrise in our body - it wakes us up and urges us to be active. The morning light enters our eyes as soon as we open them. First, light is refracted throughout the color spectrum (seven colors) through the lenses of the eyes. The light rays are instantaneously transmitted to the main gland of the organism, the hypothalamus. The hypothalamus, which regulates the body's biological clock, then transmits photocoded messages to the epiphysis (also called the third eye), which contain specific instructions for the secretion of hormones. The epiphysis secretes the powerful hormone melatonin.

Melatonin is secreted on a 24-hour cycle. Melatonin production peaks at 1:00 to 3:00 am and falls to its lowest level at noon. The epiphysis releases melatonin directly into the blood, which makes it readily available to all cells. In this way melatonin informs the cells about the time of day - that is, the position of the earth in relation to the sun. It also informs a specific DNA gene about when a cell should die and be replaced by a new cell.According to cancer research, in the event that may not secrete melatonin in time, the cell divisions will be prolonged and cancer cells will grow.

The brain synthesizes another important neurotransmitter, serotonin, which is associated with well-being. It has a strong effect on day and night rhythms, sexual behavior, memory, appetite, spontaneity, fear, and even suicidal tendencies. Unlike melatonin, serotonin increases with sunlight - its production peaks at noon - as well as with exercise and sugar intake. Interestingly, 95% of this important neurotransmitter is produced in the gut and not in the brain. This brain-gut connection shows how important it is to eat right, but also the key role that digestive function plays in physical and mental well-being and vice versa.

Fluctuations in melatonin and serotonin secretion inform cells whether it is day or night and whether they need to accelerate or slow down their activities. This phenomenon is known as "synchronization".

Consequently, the health of our cells depends on the degree to which we coordinate with the cycles of day and night. Any deviation from the circadian rhythm implies a disturbance in the secretion of melatonin and serotonin. And this hormonal imbalance disrupts the biological rhythms, which in turn disrupts all the functions of the organism: Suddenly, the person may feel out of tune, nervous and vulnerable to conditions such as the common cold, headaches, depression, and even cancer.
