Mathematical modeling of the phenomenon Spontaneous Internal Desynchrony (SID)

Abstract

Sleep is a very interesting and ancient phenomenon. Sleep is essential for all living beings, including humans. This is a special state of consciousness, as well as a natural physiological process, characterized by a reduced response to the outside world and specific brain activity. Sleep takes up a third of our lives and is the key to health. During sleep, a number of important hormones are produced, tissue regeneration occurs, and physical strength is replenished. Among the main consequences of lack of sleep are: deterioration of cognitive functions, vulnerability of immunity, overeating and excess weight, in addition, our productivity decreases.
In theory, the sleep / wake process can be represented as a non-linear system of several oscillators that works quite stably. But we live in a changing world, each at its own pace. On some days we don't get enough sleep for our norma, on some days we eat at night, and situations on the roads make us pretty nervous. All of these external signals alter our sleep patterns, at times leading to desynchronization of circadian and sleep / wake rhythms. Such phenomena were demonstrated in our work.
