A study of habits and lifestyle of American adults showed that people who sleep fewer hours consume more sweet and, mainly, caffeinated drinks. In the course of the study, an inverse association was also revealed — people consuming more sweet and refreshing beverages sleep less. Researchers interviewed about 19,000 people and found that those of them who sleep five hours or less per night, drink 21% more sugary beverages, mostly containing caffeine (coffee, cola, tea, etc). The starting point of this dependence hasn’t been found. Either sleep is disturbed by excessive consumption of caffeine- and sugar-containing beverages, or lack of sleep causes the need for energizing drinks. But scientists warn that such habits (short sleep and overdoses of sugared caffeinated drinks) may lead to obesity and heart problems.
In fact, dear colleagues, this study allows us to reformulate the well-known question about the egg and chicken in our professional realia.
