Does anyone know much about the topic of adrenaline levels during sleep (and especially during lucid dreaming)?

I honestly know nothing about it, but I'm curious how this might work. I suspect adrenaline levels might possibly the key to WBTB lucid dreaming for me.

In my experience, the only consistent method of lucid dreaming is WBTB- over an hour of staying awake intentionally, and then trying to fall back asleep (which usually takes 30 minutes to an hour). The times where I had quicker WBTB's involved being awoken unexpectedly, raising my adrenaline, and then going back to sleep. I suspect forcing yourself to stay awake at so long at 5 am and being jolted awake both increase adrenaline to a similar level. An expected alarm clock at 5 am isn't enough. And I suspect that adrenaline and awareness are linked.

Just curious, since I'd like to think of quicker ways of having LD's. Staying up for 2 hours at night really sucks and is a huge time waster. If I could increase my adrenaline quickly somehow without making much noise, maybe I could only having to stay up for 5-10 minutes to have a LD. Any ideas for that, too?
