People who wake up and “grind” at 5 a.m. are often praised like they’ve solved life. Thousands of morning routine videos on social media show people doing insane skin care routines, workouts, and perfectly balancing their macros in a smoothie. Meanwhile, the rest of us are trying to pry our eyes open before 7 o’clock.There’s a reason that an early start can look like a productivity cheat code. A lot of school and work start early in the morning. If your brain naturally clicks on early, you get more “good” hours inside the window society already rewards. Research on chronotype, your built-in timing for sleep and alertness, backs up that advantage. Studies have linked morning preference with stronger academic outcomes, including a 2013 paper in Learning and Individual Differences that connected morningness with school performance.Here’s the catch. Chronotype isn’t a flaw you can fix with a louder alarm. Genetics play a real role in where you land on the morning-to-night spectrum, and large genetic studies using UK Biobank data have found measurable heritability in chronotype, including a 2019 Nature Communications paper on genome-wide associations with morningness. Age factors in as well: teenagers skew later, while many adults get up earlier over time. But plenty of people sit in the middle.So when a natural night-leaner forces a 5 a.m. routine, the short-term glow can come from novelty and motivation. Then sleep debt collects interest, you find it hard to concentrate, and you’re way more irritable than you should be. Don’t Wake Up at 5 a.m. If Your Body Doesn’t Like ItSleep researchers also talk about “social jetlag,” which is the mismatch between your internal clock and your real schedule. That mismatch has been associated with health problems in observational research. A 2014 study in the International Journal of Obesity connected social jetlag with measures of obesity and metabolic dysfunction. A 2017 cohort study published on PubMed Central reported higher odds of metabolic syndrome and diabetes or prediabetes among people with social jetlag. None of that makes a 5 a.m. alarm sound enticing.The smarter question isn’t “Can 5 a.m. make you productive?” It’s “Can you wake early without robbing sleep?” If yes, great. If no, the grindset version of morning routine becomes a slow leak.A practical approach looks boring on social media. Pay attention to when you fall asleep easily and when you wake up without hatred. Want earlier mornings? Bring bedtime forward by 15 or 20 minutes at a time. Keep weekend sleep close to your weekday routine, get morning light, and end screen time earlier at night. Productivity happens when you’re not sleep-deprived.The post Waking Up at 5 A.M. Works Best for One Type of Person appeared first on VICE.
