How to wake up early without feeling tired
Key takeaways
- To wake up early without feeling tired, go to bed early enough to get 7 or more hours of sleep; the CDC recommends this for adults aged 18–60.
- Move in small steps. Shifting a little at a time is easier than jumping an hour or two at once.
- Get daylight soon after waking and keep evenings dim. Light and dark have the biggest influence on your body clock.
- Keep the new wake time at weekends, too.
- Expect some grogginess in the first 15–30 minutes. That is normal sleep inertia.
How do I start waking up early?
Pick your target wake time, count back at least 7 hours of sleep plus the time it takes you to fall asleep, and make that your bedtime. Then move there step by step. The sleep calculator does the counting for you and suggests bedtimes in about 90-minute cycles.
- Choose a target wake time that you can keep every day, including weekends.
- Set your bedtime from it. For 7 hours of sleep and a wake time of 6:00, you need to be asleep by 23:00.
- Move in small steps. For example, wake 15 minutes earlier every few days. This is a practical suggestion, not a research rule; adjust the pace to how you feel.
- Get light in the morning. Open the curtains or go outside soon after waking.
- Wind down in the evening. The CDC suggests turning off electronic devices at least 30 minutes before bed.
- Avoid caffeine in the afternoon and evening, and large meals and alcohol before bed (CDC).
What does a step-by-step shift look like?
An example of moving from 7:30 to 6:30 with at least 7 hours of sleep:
| Days | Wake time | Asleep by |
|---|---|---|
| 1–3 | 7:15 | 0:15 |
| 4–6 | 7:00 | 0:00 |
| 7–9 | 6:45 | 23:45 |
| 10 onwards | 6:30 | 23:30 |
Why do I feel tired when I wake up early?
Usually because the new wake time cuts into your sleep, or because your body clock still expects the old time. Grogginess is strongest when you wake during your biological night and after sleep loss, according to a 2019 review of sleep inertia research. Going to bed earlier, and giving your body clock time to adjust with morning light and a steady schedule, deal with both. See sleep inertia for more.
Can I wake up early without an alarm?
Some people do once their schedule is steady and they get enough sleep, but keep an alarm as a backup, especially in the first weeks. A gentle or melodic alarm with a slow fade-in can make waking less abrupt. Our browser alarm lets you choose a fade-in of 1, 3, 5 or 10 minutes, and our free alarm sounds work with your phone's own clock app.
Frequently asked questions
Should I sleep in at weekends? The CDC recommends going to bed and getting up at the same time every day. Sleeping in a lot at weekends makes Monday harder.
I went to bed early but could not fall asleep. What now? That is common in the first days of a shift. Keep the wake time, get morning light, and the earlier bedtime usually gets easier. If you often lie awake for a long time, keep a sleep diary and talk to a doctor.
How do I stop snoozing? Put the phone or alarm across the room so you have to get up, and set it for the time you really need to get up. See why can't I wake up to my alarm?.
