The article examines and theoretically analyzes human biological rhythms, which closely interact with the environment and respond to all circadian processes existing in the body. It has been proven that the vital activity of biological systems, their metabolism, the intensity of changes in physiological biorhythms is directly dependent on external (exogenous) and internal (endogenous) factors. The biological rhythms of the body and their impact on human performance have been determined. Depending on the daily biorhythms, certain changes occur in the body, both in the internal environment and in the emotional state, which significantly affect the dynamics of working capacity and well-being in general. Biological rhythms ensure the body's ability to adapt and survive in a changing environment, and when biological rhythms are disturbed, a person's resistance to various environmental factors decreases. The concept of biorhythmology is interpreted as a science dealing with the study of the rhythms of activity and passivity that flow in our body. Biological clocks have been revealed as an adaptive mechanism that ensures the ability of living organisms to orient themselves in time. It is based on periodic physical and chemical processes that occur in the body. Physiological and biochemical features of the human body in accordance with the chronotype are considered. Reliable differences in average indicators of glucose level, body temperature, and systolic blood pressure for representatives of the studied chronotypes were established. This is due to the fact that the spike in the level of glucose in the blood occurs at the moment of the increase in the level of the hormone cortisol, which reduces the level of melatonin and stimulating awakening in «larks». Peak concentration of this hormone is registered in the region of 4-5 hours, while in «owls» this peak is reached up to 7-8 hours. Knowing that the hormones of the «sleep-wake» cycle are involved in the regulation of all metabolic processes, including the regulation of glucose levels, changes in blood pressure. Measurements for the study took place from eight to nine in the morning, it was determined that in «larks» until this time due to full awakening there is a decrease in glucose level and blood pressure indicators, while in «owls» these indicators increase. It was also established that there is a moderate degree of linear relationship between the studied indicators. [ABSTRACT FROM AUTHOR] |
