Lifestyle, health: sleep: do hours before midnight count for double?

More lifestyle self-tutoring: the tutor begins research about the question of sleep quality before midnight vs after.

I first heard the adage “hours of sleep before midnight count for double” from a judo coach. I trust he’s probably right, though I’ve no specific idea why.

Today I started looking for a reason and encountered, where I read interesting logic that supports the claim of hours slept before midnight counting for double those after.

Olivia’s point is that the functions of sleep – starting with falling into proper sleep – are energy-expensive. Hence, the reason that when overtired, actually falling asleep can be difficult.

Olivia observes, then, that during the hours before midnight, you still have energy “left over” from the day. If you spend that energy in a productive, wakeful activity between 9pm and midnight, your body won’t have it to invest in sleep past midnight.

Olivia’s claim sounds logical to me. I know that going to bed an hour earlier, then waking an hour earlier, seems easier than staying up another hour when I’m tired.

I hope to pursue the sleep-before-midnight concept in future posts:)
