9 Ways To Wake Up On Time Without Waking Everyone Else. Only One Works.

If you're a heavy sleeper, you know the drill. The alarm goes off, you turn it off without remembering, and you wake up late. Or it goes off at full volume, your partner groans, and now two people are awake when only one needed to be.

1. The loudest alarm your phone has

It wakes up everyone except you. Your brain learns to tune out the same sound.

2. Five alarms, five minutes apart

You snooze all five.

3. Phone across the room

You get up, turn it off, and get straight back into bed.

4. A sunrise lamp

Heavy sleepers sleep right through it, and it lights up the room for your partner.

5. A maths-puzzle alarm app

Now you're awake, angry and solving equations at 6am. So is your partner.

6. Going to bed earlier

It helps, a bit. It doesn't stop you sleeping through the alarm.

7. A smartwatch

One short pulse that heavy sleepers barely notice, and it needs charging every night.

8. Asking your partner to wake you

Works until they get fed up with being your alarm clock.

9. A silent vibration alarm on your wrist

This is the one that works. A soft band vibrates on your wrist and gets stronger until you're up. No sound at all, so the person next to you keeps sleeping.
