“You possibly can’t skimp on sleep one evening and anticipate you’ll ‘catch up’ the following,'” Bono mentioned.

Bono’s examine, revealed lately in Psychology, Well being & Drugs, tracked the sleep habits of 97 Washington College first-year college students throughout their first semester on campus. The scholars who reported probably the most steady, constant sleep patterns earned a GPA of three.66, on common, whereas the scholars with probably the most variable sleep earned a GPA of three.21. College students with common sleep patterns additionally reported greater ranges of well-being. These results held even when controlling for SAT scores and baseline happiness.

Bono additionally tells college students to cease scrolling an hour earlier than sleep as the sunshine that emanates from units suppresses the discharge of melatonin, the hormone that makes us drowsy.

Most significantly, do not compete within the Struggling Olympics.
