By "being mildly active physically", I mean simple things such as cooking, rearranging the bookshelf, cleaning the espresso machine etc, which also require mild mental concentration. When I do these things, sleepiness goes away. Anything more active than that will make you tired and sleepy too soon.
Oh, that I can do. I'd initially thought you meant outdoor activities by "being mildly active physically", and I'm not all that sporty.
@Kiprobalhato I'm a pretty deep sleeper, so once I'm asleep, you could place a loudspeaker next to my ear and I wouldn't wake up. I have minor problems with light when trying to sleep, but that's only when I'm not too tired. If I'm tired, it doesn't affect me that much.
