Start with a location mission outside the bedroom: bathroom barcode, kitchen photo, curtains, or shoes. Add a wake check if you can't trust yourself to stay up.
Choose based on the failure, not the toughest option
If you never hear the alarm, you may need sound, vibration, light, and medical attention if the problem is severe. If you hear it but dismiss it automatically, you need distance. If you finish a task and go back to sleep, you need a follow-up check.
Heavy sleepers often do better with a mission that changes location. A math problem in bed may become part of the dream. A barcode by the sink is harder to complete without entering the morning.
Keep the mission fair enough to trust
Pick a task that takes thirty to ninety seconds when awake. Test it at night. Make sure the route is safe, the lighting works, and the target will not move. Then add the first real action nearby: clothes, water, medicine if prescribed, coffee, or shoes.
If even strong missions do not wake you or you remain dangerously sleepy, do not keep escalating. Talk with a healthcare professional, especially if there is snoring, gasping, headaches, or daytime sleepiness.
Common questions
Are physical missions best for heavy sleepers?
They can help some people, but a location mission may be safer and more repeatable than intense exercise immediately after waking.
Should I use more than one mission?
Use one primary mission and a wake check if needed. Too many tasks can make the setup feel like punishment.
