What the trial is, and whether it could suit you
The physiological processes of the body present daily oscillations called circadian rhythm. The circadian rhythm is essential for maintaining the vital functions of organisms, intervening directly and indirectly in a multitude of key processes, such as hormone secretion, cycles of activity and rest throughout the day, body temperature, the metabolism or absorption, processing and detoxification of nutrients. There are factors such as certain work schedules, prolonged exposure to screens, certain eating patterns or social jetlag, which have a negative impact on the circadian rhythm, causing its disruption and favoring the appearance of health alterations. Thus, there is evidence that associates night shift work with a higher incidence of risk factors for developing metabolic syndrome and cardiovascular diseases, including obesity, elevated blood levels of glucose, triglycerides, and low-d
