Staying up all night doesn't leave anyone feeling refreshed, revitalized, and ready to go. (Anyone who's pulled an all-nighter knows the next day can leave you feeling like a zombie chasing a caffeine drip.) But for many people—doctors, bartenders, call attendants, or police officers who work night shifts—working all night is a day-to-day reality.
The problem is, shift work doesn't just leave us zonked. The World Health Organization considers it a probable carcinogen—and research suggests that if you spend your nights wide awake, you're more likely to suffer not just from certain kinds of cancer but also diabetes, cardiovascular disease, obesity, and cognitive impairment. (In fact, it could be the culprit behind your recent weight gain.)
That's why many overnight workers fight back harder, mastering the art of maintaining a healthy diet, an exercise schedule, and a sleep routine despite less-than-ideal circumstances. So next time you find yourself lacking serious Zzzs, consider their tips to find energy and make it through the day like a healthy human.
