There are some health determinants that we can’t do much about such as those that are marked by our genetic endowment, our family, the place where we have to live and the historical moment that is contemporary to us. Other factors, however, are linked to the lifestyle we decide to lead, such as sleeping well (in quantity and quality) a factor that doesn’t yet occupy a prominent place in the collective imagination. However, many studies aim towards common sense: if one sleeps well, the next day is better, and vice versa. That is why I was not surprised by the finding of a Finnish research that associates sleeping insufficient hours with drowsiness and life quality for adolescents or another collected from Harvard Health Publications that limited sleep to five hours a night for one group of students at the Singapore institute for a week and compared their abilities to another group who had slept for nine hours each night, with predictable results of cognitive impairment due to lack of sleep.
