My question: what is the difference (physiological ? brain chemicals ?) between people able to fall asleep in 5 minutes after they close their eyes anywhere, and those (like me) who can never do it in less than 1 hour ?
From what I've seen in the lab and first hand (I can fall asleep in seconds, no joke), is that a low latency of sleep (time it take to drift off) is accountable most directly to keeping the same sleep schedule day after day and getting enough sleep each night. This is so important because your body should be your best sleep aid due to the circadian rhythm that produces melatonin to cause your sleep drive to start. If you miss that critical 2-3 hour "window" when sleep drive is most effective then you may experience some difficulty with sleep onset once you do decide to go to sleep.
