But here’s the good news: The foods you eat and—and more importantly when you eat them—can help “reset” your body’s sleep clock, according to a new study from the United Kingdom.
A single night of poor sleep is enough to throw off your body’s circadian rhythms, which determine when you feel sleepy and when you feel alert and awake, says study author Felino Cagampang, PhD, a senior lecturer at the University of Southampton. While exposure to sunlight plays a large role in regulating your sleep cycle, Cagampang’s research team found that your diet can actually override your circadian clock, and can help you overcome jet lag, a wonky work schedule, or a few nights of inconsistent sleep.
How? It’s complicated, but it has to do with something called the “food entrainable clock,” which is regulated by your brain’s hypothalamic region, Cagampang says. Put simply, eating trumps sleeping when it comes to your brain’s survival hierarchies, and so your body’s food clock is able to dictate terms to your body’s sleep clock, says Cagampang.
