Research published in the Melbourne Institute Working Paper Series in February suggests that a three-day workweek could be best for adults 40 and older – but that’s the sweet spot. Once adults are older than 40, however, the number of work hours packed into a daily schedule may have health effects similar to the schedule itself. “Some of these waste products can be harmful for your neurons,” Benedict said. Since shift workers often experience sleep disturbances or may not get enough sleep, their brains might not effectively remove waste, Benedict said. Sufficient sleep benefits the brain since, as you snooze, the organ can flush out cellular waste that builds up during wakefulness, previous research has shown. “However, as of yet, a mechanistic explanation as to why shift workers require at least five years of time-out to recover their cognitive performance is lacking, and as such warrants further investigation.” “The latter could suggest that it may take at least five years for previous shift workers to recover brain functions that are relevant to the performance on this test,” he said. “If you are forced to working irregular shifts for the sake of money, make sure that you are physically and mentally active.” “In other words, do your grandparents or parents have type 2 diabetes, obesity or heart diseases? If yes, it might be better to go for a ‘9-to-5’ schedule,” he added. “It is important to check on your familial predisposition for diseases that have been previously linked to working irregular shifts,” said Christian Benedict, a researcher in Uppsala University’s department of neuroscience in Sweden. Research also indicates that these preferences are linked to your genes.īut whether you’re more of a morning or evening person, many studies consistently show that irregular or overnight shift work can have a negative impact on your health. Mid-20s and 30s: Shifting away from shift workįor most adults in their 30s and 40s, some studies suggest that ideal work schedules should mirror individual preferences, whether you are an early riser or a night owl. This association especially emerges in adults who work late-night or overnight shifts.

Jess Shatkin, a psychiatrist at the Child Study Center at NYU Langone Medical Center.Īs a result, “adolescents have this desire to go to bed later and wake up later, and that’s what most people do until they hit around 26,” Shatkin said, and it partly comes down to melatonin, a hormone linked to your biological clock that influences when you start to naturally feel sleepy at the end of the day.ĭoctors: Early school start times unhealthy for studentsĭelaying high school start times for a school district in Kentucky resulted in its students getting more hours of nightly sleep on average and its teen drivers having fewer car crashes, according to a 2008 assessment of the district published in the Journal of Clinical Sleep Medicine.Ī separate two-year study of school districts in Virginia, published in the same journal in 2014, found similar results indicating a reduction in crash rates.įor both adults and adolescence, insufficient sleep is associated with a number of chronic diseases and conditions, such as diabetes, cardiovascular disease, obesity and depression, according to the Centers for Disease Control and Prevention. Teens and young adults: Later may be betterĮven though you are legally an adult when you turn 18, your brain may not grow out of adolescence until your mid- to late 20s, said Dr. From your adolescence to post-40, here are the schedules that research suggests may be the best for your age: So you tend to require different work schedules and work hours throughout your lifetime. Those circadian rhythms can slowly change as you age. Scientists have long known that you have an internal biological clock that regulates various physical, mental and behavioral changes your body experiences over a 24-hour cycle, called circadian rhythms. Lazy summer days have come to an end, and more structured back-to-work or back-to-school schedules have commenced.īut will your new daily schedule be the healthiest for your brain and body? The moment you may have been dreading is here.
