The benefits of sleep can’t be overstated. “Good sleep guarantees wellbeing and mental health,” according to a study published on US National Library of Medicine.

Sleep problems are also linked to metabolic syndrome and, thus, obesity.

A study published in the American College of Occupational and Environmental Medicine concludes that, “insomnia and disturbed sleep…are associated with decreased job performance and productivity.”
