[Physical activity and aromatherapy as positive factors influencing the quality of sleep]

Human sleep is a state of abolished consciousness controlled by circadian rhythms. It is divided into two phases depending on the electrical activity of the brain: NREM and REM, during which dreams may occur. Sleep has a key impact on a person's emotional, physical, and cognitive well-being. There are specific differences in physiological and biochemical processes during sleep. Adenosine and melatonin are involved in the regulation of circadian rhythms. During sleep, you can observe the secretion of growth hormone, a reduction in cortisol secretion, and a decrease in muscle tone and blood pressure. Longterm lack of sleep increases the risk of obesity, diabetes, cardiovascular diseases, cognitive disorders, and psychiatric diseases. Sleep disorders affect more and more social groups. The analysis of one's own circadian rhythms associated with the identification and adaptation of behaviors described as factors influencing sleep may have a positive impact on the optimal functioning of the body. It has been proven that physical activity and aromatherapy can have a positive effect on the quality of sleep. The aim of the study is to review of literature aimed at identifying selected factors influencing the quality of sleep together with a discussion of their importance for human health.
