I might try using one of these instead of what I currently use (a cheap radio alarm set to static white noise); I've noticed that sunlight on my face seems to be a strong factor in consistently waking me up.

Have you ever fallen asleep in the sun? ie. does this apply to just mornings after a good sleep, or does sunlight block sleep for you?

I'm not sure if sunlight blocks sleep completely, because it's also correlated with warmth which does help with sleeping. It's probably more to do with circadian rhythm.

For two years in college, my bed and window were positioned just so, that sunlight would target my pillow at around 10-11 am, and I found I consistently woke up around then in the absence of an alarm, independent of how long I slept (within reason.) These days I still seem to have a harder time waking up if it's overcast rather than sunny. But to answer your question, I can't recall any instances when I fell asleep in the sun; I might even have a habit of closing the blinds to sleep, if it's still light out.
