Researchers found that drivers involved in sleep-related crashes were four to five times more likely to work night-shift jobs and had built up 'sleep debt' or gotten far too little sleep before driving. These drivers often relied on ineffective tactics like opening windows or turning up the radio, and put themselves and others at risk ...
A study of 11 young men found that sleep debt increased glucose concentrations in the blood, while altering cortisol levels and thyroid hormone regulation. The research suggests that persistent sleep debt may exacerbate age-related chronic disorders.
