I get up about two to three times a night. I'm not sure why, as there are multiple explanations. I go to the toilet, drink some water, and go back to bed. That takes about two minutes. In this research, people were forced to wake up every hour and then stay up for 20 minutes. Then I would feel totally different - I have no doubt. After twenty minutes, probably in bright light, I would be awake and that would disrupt the sleep cycle totally. This might be the case when you have a small kid, but how often does this happen (in the real world) with these frequencies? With me this is not the case. It feels natural. I don't put the light on - I can find my way without it. It takes two or three minutes, and that's it. Back in bed I fall asleep right away. This research is presented here as if this would influence my mood? I don't know. I guess I can sleep better, but this is not the explanation that works for me.
