How to become a morning person (when you’re a night owl)

Sunday, 12:50 a.m. Lights have been off since 11. The phone is face-down on the nightstand, Monday’s 6:30 alarm already set, and you’re staring at the ceiling, wide awake.

Saturday you slept until 10. Best sleep of the week. That’s exactly why you’re still up.

It feels like proof you’re a night owl. It’s closer to the opposite. Your body clock moved, and fast. It just moved the wrong way this weekend.

Can you become a morning person, or is it genetic?

You can. Genes set a lean, not a sentence. In 2019, researchers searched the DNA of 697,828 people from UK Biobank and 23andMe for links to being a morning person (Nature Communications). Then they checked sleep timing in the 85,760 who had worn activity monitors.

The 5% carrying the most of the known morning-type variants slept, on average, 25 minutes earlier than the 5% carrying the fewest. The variants found so far explain only part of chronotype, but they put the two ends of the scale just 25 minutes apart.

So “I’m just not a morning person” is rarely a full DNA verdict. Not everyone buys that. “Night owls don’t turn themselves into morning people. Night owls cope with rising early,” says one Redditor. That stranger is half right, as the best study on the question found.

How night owls moved their body clock 2 hours in 3 weeks

In 2019, a University of Birmingham team recruited 22 healthy night owls whose average night ran from about 2:30 a.m. to 10:15 a.m. (Sleep Medicine). Twelve of them got three weeks of new rules to follow at home; a control group of ten didn’t.

After three weeks, the rule group’s sleep and wake times sat about 2 hours earlier, measured by wrist trackers and by the timing of melatonin and cortisol, with no drop in total sleep. They also reported less stress and depression, and did better on morning reaction-time tests. The groggy first minutes after the alarm are a different thing, sleep inertia, and they don’t prove you’re an owl.

Now the half the Reddit poster got right. Their peak performance moved from evening to afternoon, not to morning. You can become someone who’s asleep by midnight and alert at 9. You may never love 6 a.m. Twelve people on the plan is a small study, so treat it as a strong sign.

How to shift your sleep schedule earlier

Pick the wake time first, the one you’ll keep on Saturday too, then count back to a bedtime. The bedtime math for 4, 5 and 6 a.m. is already done.

Made-up example, not a study. Noor, 27, a UX designer in Minneapolis, falls asleep around 1:30 and logs on from home at 9:00. Her new job wants her at the office at 8:30, so she sets 7:00 for every day of the week. Day three, 9:40 p.m., she’s on the couch with the remote, eyes closing mid-episode. For the first time in years, that feels like a win. If your first week looks like hers, the sleep debt calculator shows what those short nights cost.

Do you have to wake up at the same time on weekends?

Yes, and this is where most attempts die. In a 2008 study, 16 volunteers kept their usual bedtimes and changed one thing: on Saturday and Sunday they got up about 3 hours later (Sleep and Biological Rhythms). By Sunday night, their melatonin onset, the start of the body’s night, had slid 42 minutes later.

They took 8 minutes longer to fall asleep that night, and felt sleepier and more tired on Monday and Tuesday. The authors called it the “Monday morning blues.” That’s your 12:50 a.m. ceiling, measured.

One r/ADHD thread is blunter: “If you try to revert on the weekend you will fail.”

Apple’s own help page for sleep schedules in the Health app gives, as its example, one schedule for weekdays and another for weekends. Our reading, not Apple’s advice: while you’re shifting, use one schedule for all seven days. You don’t become a morning person on weekdays. You become one on Saturday.

Can an alarm app make you a morning person?

No. An alarm decides when you get up. It doesn’t move your body clock; light and a fixed schedule do that.

What Risly can do is hold the line on the morning the method usually fails: Saturday at 7. Its alarm stops when you finish a mission, like a few math problems or the one called Make your bed, and snooze is off by default. It runs on iOS 26 and later only, and if you’d rather be eased awake, a sunrise lamp suits you better. If the weekend alarm keeps turning into three snoozes, that’s its own fix, and if you sleep straight through it, start there.

How to use morning light to change your chronotype

Get outdoor light early, and the later your clock runs, the more it pays. For a 2013 study, researchers sent eight adults camping in the Colorado Rockies in July (Current Biology). First a week of normal life, then a week in tents with sunlight and campfires only: no flashlights, no phones. Then straight from the campsite to the lab for a melatonin test.

Their body clocks had moved about 2 hours earlier, and the later chronotypes moved the most. Their first two hours awake: about 3,074 lux outdoors, against 934 in their normal week. Eight people, one summer, no control group: a pointer, but it points the same way as Birmingham’s “maximize outdoor light.”

You don’t need a tent. Our rule of thumb: some time outdoors in the first hour after the alarm, every day, then lamps low after dinner. Clocks fall back on November 1, which puts more daylight into early mornings for a few weeks.

Night owl or delayed sleep phase disorder?

Some night owls aren’t just late. The American Academy of Sleep Medicine describes delayed sleep-wake phase disorder as a sleep pattern “delayed by two or more hours from societal norms,” and says about 7% to 16% of teens and young adults may have it.

Our line, not the AASM’s: if you’ve held one wake time and morning light for a month and still can’t fall asleep before 2 or 3 a.m., or the late schedule is costing you a job or a semester, see a doctor or a sleep clinic. Delayed sleep phase is diagnosable, and treatable.

What to do tonight

1. Choose one wake time for all seven days, this Saturday included. The Birmingham owls moved 2 to 3 hours; if that scares you, start with one.
2. Set it once. If your Health app has a separate weekend schedule, make it match the weekday one.
3. Put your shoes and a jacket by the door so the first thing you do tomorrow is step outside.
4. Turn the lamps down after dinner, and get dinner done by 7.

A few weeks in, you may start to wake a few minutes before the alarm. That’s the clock moving. And next Sunday at 12:50 a.m., you should be asleep.
