What is Circadian Rhythm? Our Body’s Invisible Cycle

what is circadian rhythm

The waves and magnetic energy generated by the rotation of the earth around its own axis for 24 hours do not only affect the materials, but also the balance and functioning of our body as much as they do. In short, it is possible to define biochemical, physiological, operational and biological fluctuations that occur during the rotation of the earth as a cycle of changes. This cycle is known as the circadian rhythm .

Circadian systems are not stray balances, they are in interaction and solidarity with the universe, human and nature. It is possible to define this balance as the organic clock of our body. It is possible to see this structure through chronically repetitive cycles in our body.

Sleep-wake state, blood pressure, working performance of the heart, secretion of growth hormone, sleep hormone and the combination of various hormones. The circadian rhythm biologically encompasses such rhythms. So what affects the circadian rhythm? Let’s see together.

What Factors Affect the Circadian Rhythm?


Light is one of the factors that most affect the circadian rhythm. Artificial elements such as telephone light, which we are frequently exposed to in daily life, intense light in shopping malls and computer light, can disrupt the light rhythm balance. Another important factor affecting the circadian rhythm is sleep.

Disruptions in our sleep disrupt the rhythm. Melatonin hormone secreted for sleep is secreted between 21:00 and 22.00 until 03.00-04.00. Not sleeping between these hours breaks this rhythm. Temperature is another factor that affects it.

In extreme heat, the sweat balance of the body may be disturbed or it may cause some changes and damages on the skin by creating an excessive tan. In extremely low temperatures, it causes the body to contract itself excessively and to slow down the body balance.

Sleep and Nutrition Are Extremely Important

Nutrition is one of the elements that provide a rhythm that keeps our body in balance. We survive with nutrition, our main energy store. Disruption of this nutritional balance leads to a deviation of the circadian rhythm, that is, the body’s clock may go wrong. While the work of enzymes is tied to a certain time, that is, the person has settled this into a routine with his diet, the disruption of this balance also deviates the circadian rhythm.

Such deviations can lead to malnutrition, extreme thinness and extreme obesity. Failure to sleep in the time zone in which melatonin is secreted will lead to deviations in sleep and changes in nutrition. This will lead to consequences such as loss of appetite, diabetes, and weight loss.

Under What Conditions Can the Circadian Rhythm Be Disrupted?

  • Insomnia,
  • irregular diet,
  • heavy drugs and radiation,
  • Menopause and Andropause,
  • psychological problems,
  • Exposure to insufficient or excessive light.

What Can We Do to Maintain the Circadian Rhythm?

We have said that the most important factors that provide the balance of the body are nutrition and sleep. Therefore, the circadian rhythm will be sustained by two dominant elements. That’s why we have to be extremely careful about our sleeping hours, sleeping in the dark is very important in this context. Sleeping during the hours when melatonin hormones are secreted also positively affects growth and development.

We must avoid exposure to radiation and harmful energy waves. In addition, some harmful rays taken from the fingertips in touch phones can kill the cells at the ends and change blood pressure in the opposite direction.

Exposure to chemical structures and chronic exposure to industrial products while cleaning are other factors that disrupt the balance. In addition, consumption of alcohol and cigarettes disrupts the balance of the lungs, heart and liver. We should stay away from these as much as possible and listen to natural products and the installation of our body clock.

Is There a Treatment for Circadian Rhythm Disorder?

Rhythm Disorder

If the person with circadian rhythm disorder goes over some abnormal trends in himself, he can make some judgments by listening to himself. Individuals who have sleep problems can use drugs in a dark room or with the approval of a doctor. One of the treatment methods is to create healthier products and a more routine nutritional balance by going over the diet. Methods such as adjusting the carbohydrate balance and reducing nutrients such as sugar can be used. In this context, working with a dietitian will yield beneficial results and be positive for balance.

To sum up, the circadian rhythm somehow completes its cycle during the day based on biological and physiological factors in our body within 24 hours. Sleep and nutrition are the most important factors that affect this natural clock that works like a clock in our body. For people who are social creatures, it is not always easy to maintain some balance.

Psychological factors, the environment we live in always affect our circadian rhythm. Therefore, they are in mutual communication. Although biological factors affect this natural clock of our body, it is also undeniably important in psychological effects. At this point, perhaps the foremost option would be to listen to ourselves.

When attention is paid to the reactions of our body, it will not be difficult to see the things that go wrong with us, the routine element of the cycle. Just as life consists of night and day, there are also these two different aspects in human life. Sleep and wakefulness. It is extremely important to listen to the rhythm of our sleep at night, as we become aware of ourselves when we are awake. Because all these routines are part of the circadian rhythm. Our body is connected with the universe.

If we become aware of this balance in our body, our self-awareness for our health will increase. This will lead us to the correct determinations at some points as we have gained knowledge about ourselves. Accurate determinations will enable us to reach a solution even sooner. Just as nothing in the universe is in vain, no reaction or correlation that takes place in our body is in vain, and the circadian rhythm is just one of these elements.
