Chronobiology is a highly interdisciplinary division of the sciences which is concerned with the study of scientific rhythms and cyclic procedures in living organism, such as animals, plants, bacteria, and fungus. People who work in this field can apply it in various ways, which range from dealing patients with sleep disorders to studying the procedures involved in the development of mold colonies. Some illustrations of areas incorporated into chronobiology include: molecular genes, anatomy, physiology, actions, science, cell biology, and chemistry.

Chronobiologists can be discovered in the field and the lab, dealing with a wide range of living organisms. Knowing the time-dependent procedures involved in growth and ordinary performing can be very important to understanding an organism, or to monitoring down signs which provide information about a particular organism, environment, or interconnected system. Chronobiology can even be used in forensics; for example, a researcher can use known time-dependent activities such as the life-cycle of insects to figure out time of death.

How does Chronobiology works?

An image displaying the chronobiology• The human body has a hierarchy of scientific rhythms and a number of scientific clocks.

• Biological rhythms program how the human body works: diet, physical and intellectual activity, sleep. They depend on heredity.

• The most apparent synchroniser is day/night alternance.

• Biological clocks are situated in body parts such as the brain, liver organ, kidneys and help set up and balance the biological rhythms. They are completely connected to the environment and synchronised with it.

Is Chronobiology applied to Nutrition?

Chrononutrition allows the body to be provided with a nutrient (or nutrients) at the accurate moment it needs it most or when it will have most impact on our physiology.

Secretions connected to food intake are diverse: enzymatic, hormonal. They are not continuous for the same type of meal or all through the day. This means that the body will get more or less benefit from a food depending on what time of day it is consumed.

If we take the specific problem of excess weight, we can see that adjustment to activity patterns recently has affected eating styles.
