How to wake up early (and actually feel awake): what the research says

How do you wake up early?

To wake up early, move your wake time earlier in small steps, keep it the same every day and get light soon after you get up. Your body runs on an internal clock of roughly 24 hours. That clock decides when you feel sleepy and when you feel alert, and it does not like sudden jumps. Moving your alarm by about 15 minutes every few days gives it time to follow.

The other half is bedtime. If you want to wake an hour earlier, you need to fall asleep about an hour earlier too. Adults need at least 7 hours of sleep, so waking early only lasts when your sleep moves with it, not when it gets shorter.

How do you shift your body clock earlier?

Light in the morning is the strongest signal for moving your body clock earlier. Daylight tells the clock that the day has started, and light late in the evening pushes it later. Modern life gets this backwards: we sit indoors by day and look at bright screens at night.

A 2013 study in Current Biology took people camping in summer with only natural light. Their body clocks lined up with the sun, with the biological night ending just after sunrise. The people with the latest clocks moved the most. You do not need a tent for this. Step outside or sit by a bright window soon after you wake, and dim the lights in the last hour before bed.

Can a night owl become a morning person?

Yes, many night owls can move their timing by a couple of hours with daily habits. In a 2019 randomised trial, night owls woke and went to bed earlier, got light in the morning, ate at fixed times, timed their caffeine and exercised. Their sleep and wake times moved about 2 hours earlier, with no loss of sleep time. They also reported less stress and depression, and their reaction times and grip strength in the morning improved.

What made it work was doing the same things every day. Here is a simple version of that routine:

• Wake at the same time every day, weekends included.
• Get light within the first hour.
• Eat breakfast, lunch and dinner at fixed times.
• Keep caffeine to the morning.
• Move your body during the day, not late at night.

Your genes set part of your timing, so a strong night owl may never love 5 am. But almost everyone can move a little earlier.

How do you wake up early without feeling tired?

You feel less tired when you get enough sleep and give the first minutes after waking time to clear. That heavy, foggy feeling right after you open your eyes has a name: sleep inertia. A 2019 review describes it as a drop in thinking and performance that fades the longer you are awake. It is stronger after a short night and depends on the time of day you wake.

Waking from deep sleep makes it worse. Sleep runs in cycles of about 90 minutes, and some people time their alarm for the end of one; we explain how in how long is a sleep cycle. If you hit a slump later in the day, a short nap of 10 to 20 minutes helps without leaving you groggy, as we cover in power nap length.

If you sleep 7 hours or more and still feel exhausted most mornings, talk to a doctor. Snoring, waking often or feeling low can all point to something worth checking.

What should you do in the first minutes after waking?

Get up, get light and give your brain something steady to wake into. Open the curtains or step outside. Drink a glass of water. Move a little, even just a stretch. Leave your phone’s feeds for later, because a scroll in bed is how ten minutes becomes forty.

Some people like gentle sound for those first minutes. Shimmr has no alarm, so use your phone’s own alarm to wake up. Once you are up, the Flat → Bright Shift is a 10 minute binaural session that glides from Alpha, a relaxed waking rhythm, to Beta, the rhythm of alert thinking. We explain what those rhythms are in beta waves. Listen with headphones while you make coffee or get ready.
