But did you know that we can actually experience jet lag without traveling across the world? He explains what’s known as “social jet lag,” a concept that afflicts all of us who spend our Friday and Saturday nights staying up late with friends, watching movie marathons, and sleeping until we roll out of bed for a late brunch. All of these activities lead to a disrupted sleep routine that we desperately try to amend throughout the workweek—only to mess up again when Friday rolls around. While we’re definitely not going to tell you to cancel plans in order to optimize your sleep schedule, there are a few tips you can follow to ensure you are back on track before Monday morning starts. Here are Dow’s four hacks to get an ideal night of sleep, every single night: “Pitch black is best,” he tells me. Some people love to wake up to the natural morning light in their eyes, which has its known benefits as well. But if you live in a crowded city that seems to light up your room with fluorescence, it may be best to draw the curtains while you sleep. Or, as Dow suggests, you could purchase an eye mask. That way, you can ensure a pitch-black sleep at night and wake up with the morning sun. It’s like you’re almost tricking your body into “sleep mode.” By creating conditions that mimic your body’s natural sleep cycle, you can accelerate that process. That’s why, according to Dow, you should turn your thermostat down to 67 or 68 degrees an hour before getting in bed. If you and your partner ever bicker about keeping the fan on at night, consider this a doctor-approved case to keep it cool. But Dow says that sleeping in late to make up for a night of poor sleep only puts you further behind in your quest for an ideal sleep schedule. Instead, you should try to wake up at your normal time, no matter what time you eventually fell asleep that night. Dow calls this process sleep “compression and expansion,” which essentially means you should actually sleep less to end up sleeping more. “If you go to bed and wake up at your normal time, that sleep compression will help you to sleep really well the next day and will keep your circadian rhythms in sync,” he says. So, even if you’re feeling especially sleepy one underslept night, don’t snooze that alarm. It may be best to gulp down some coffee and try going to bed early that night. Whether you opt for a magnesium supplement or another over-the-counter, natural sleep aid, a sleep supplement may be what it takes to get some much-needed shut-eye.* We know we don’t need to remind you how crucial your sleep is to your overall well-being. These four tips can help you optimize your sleep routine, whether you’ve returned from a trip across the world or from a Saturday-night soirée. Here’s to combating social jet lag—and to better sleep hygiene as a whole.
