How to Wake Someone Up (Even a Heavy Sleeper): 9 Methods That Work
The most reliable way to wake someone up is to combine light, sound and touch, gently at first and then stronger. Open the curtains or switch on a bright light, say their name in a normal voice, then a bit louder, and put a hand firmly on their shoulder. Stay until they sit up, because heavy sleepers often answer and fall straight back asleep. For the long run, the real fix is helping them wake up to their own alarm.
Key takeaways
- Start with light and their name, then add touch. Stack signals rather than jumping to shouting.
- Stay until they are sitting up or standing. A mumbled answer is not being awake.
- Waking someone near the end of a sleep cycle is easier than from deep sleep.
- Avoid cold water, hard shaking and loud surprises. They make people groggy and annoyed, not alert.
- If you wake the same person every day, help them set an alarm they cannot snooze instead.
Why are some people so hard to wake up?
Some people really do sleep more deeply than others. How easily someone wakes depends on which stage of sleep they are in, how much sleep they are missing and their own biology. Deep sleep, also called slow-wave sleep, is the hardest stage to wake from, and there is more of it in the first half of the night. Someone who is short on sleep spends more time in deep sleep and is harder to rouse at any hour.
The other problem is sleep inertia, the groggy state right after waking. Someone can open their eyes, talk to you and even agree to get up, then fall asleep again with no memory of the conversation. That is why "I woke them, they said OK" so often ends in them being late. Our guide on why people sleep through alarms explains the causes in more detail.
9 ways to wake someone up
- Let the light inOpen the curtains or switch on the main light. Bright light tells the body clock it is morning and makes it much harder to drift off again. In winter, a bright lamp near the bed works too.
- Say their namePeople react to their own name even in light sleep. Start at a normal volume, then say it louder and more clearly. Repeat it rather than shouting once.
- Use touchA firm hand on the shoulder or upper arm, or a gentle squeeze of the hand, is often what finally gets through. Avoid the face and do not shake hard.
- Turn up a sound slowlyPlay music or a radio that gets gradually louder. A rising sound wakes many people more gently than a sudden blast.
- Time it with their sleepIf you can, wake them in the last part of their night instead of 30 minutes after they fall asleep. Waking from lighter sleep is easier and less groggy.
- Bring in cool airOpening a window or pulling the blanket back a little lets cooler air in. People sleep best warm and cosy, so a bit of cool air makes staying asleep less comfortable.
- Use a smellFresh coffee or breakfast cooking is a classic for a reason. Smell alone rarely wakes a deep sleeper, but it helps someone who is half awake actually want to get up.
- Ask a question they have to answer"What time is your meeting?" makes the brain work more than "time to get up". Thinking speeds up waking.
- Get them uprightAsk them to sit up and put their feet on the floor while you are still there. Once they are standing, the hardest part is over.
Which method works for which situation?
| Situation | Best approach |
|---|---|
| Partner who slept through the alarm | Light on, say their name, hand on the shoulder, wait until they sit up |
| Teenager before school | Curtains open, two clear warnings with times, then stay until feet are on the floor |
| Friend after a late night | Light, water by the bed, a question they must answer, cool air |
| Very early flight or shift | Agree the plan the night before, use their alarm plus your check-in |
| Someone you wake every single day | Help them set up their own alarm that cannot be snoozed |
What should you avoid?
- Throwing water or ice. It is a shock, not a wake-up, and it starts the day with an argument and a wet bed.
- Shaking hard or pulling them out of bed. It can hurt, and people woken roughly from deep sleep can lash out without meaning to.
- Air horns and sudden loud noises. A sudden fright spikes the heart rate and leaves people irritated and still foggy.
- Waking a sleepwalker forcefully. Guide them back to bed calmly instead. If you need to wake them, use their name and a light touch from a little distance.
- Leaving after the first answer. This is the most common mistake. Wait until they are up.
How do you wake someone who has had very little sleep?
Expect more grogginess and more repeated attempts. Use bright light first, keep the room cool, give them water, and get them moving quickly. Once they are up, natural light and a short walk help more than another ten minutes in bed. Our guide to waking up after a late night covers the first hour.
When should you worry about someone who will not wake up?
Being hard to wake is common. Not being able to wake someone at all is different. If a person does not respond to loud voice and firm touch, is breathing unusually, or may have taken alcohol, drugs or medication in large amounts, call emergency services. Regular extreme difficulty waking, loud snoring with pauses in breathing, or heavy sleepiness during the day are also worth a visit to a doctor.
How do you stop being someone else's alarm?
Waking an adult every morning wears on both of you. The long-term answer is an alarm that does the job for them. That means an alarm that is loud enough, placed out of reach, with no snooze, and with a task that has to be finished before it stops, so it cannot be switched off half asleep. Our step-by-step guide on how to wake up as a heavy sleeper walks through the setup.
How Awaken helps heavy sleepers wake themselves up
Awaken is an iPhone alarm built for exactly the person you keep having to wake. There is no snooze. To stop the alarm they have to finish a challenge, such as solving math problems, doing squats or jumping jacks, scanning a barcode in another room, or taking a photo of the sky. The optional Wake-Up Check asks them to confirm they are still up a little later, and if they ignore it, the alarm comes back. A morning streak makes getting up on time something to keep, not just something to survive. That way you can check on them without being the alarm.
