The player answered question about their sleep - wake cycles , sleep timbre and lifestyle habits , such as how often they exercise .

But femalenight owlshad only a 2.2 - fold increase risk of metabolic syndrome , a bunch of factors that raise the risk of affection disease , stroke and diabetes , the researcher ascertain .
" consider even type is more prevalent in the younger years group , these finding are [ an ] important major health outlet , " Kim said .
