Most people don't have a problem with getting out of bed, they have a problem of getting into it.
There is certainly some who have genuine medical problems and so who struggle. An order of magnitude just don't sleep enough though. Go to bed at 10 and it's easy to get up at 6, or whatever your actual sleep need is (it varies by individual and over time, right now mine is a hair under 8h I think).
Problem is I'm getting home from work 7-8pm. Housekeeping, food, then rest, and I need to let my mind decompress before going to bed. That takes me past midnight. The only people I've seen do this over decades are very type A and/or they finish every night with a few drinks of alcohol. I don't drink.
My routine is leaving for work at 7.00, getting home 19.15 or so, have a soup for dinner to avoid food time (pre made) and then about 2.5h of relaxing/hobbies, being in bed 22.00-6.35. I get showering and exercise in at work, apart from hobby exercise like sea swimming/walking that fits into those 2.5h.
Mostly I stick to this routine because I get a lot more stuff done with a full nights sleep, I am a lot less good even on 7h so by now I know not to even try to compromise on that.
I also don't drink, so that's not an option (and I think a lot unhealthier anyway).
No kids make this a lot easier than for people with families though.
This. Every other advice is just fighting a symptom not addressing the root cause.
We have all experience having really deep refreshing sleep at least once in our life. As well as fragmented or shallow sleep that makes us feel groggy in the morning. It's obvious which type is easier to wake up from the morning after
Very true in my case. Although the problem of me getting into bed early is the vicious circle that quickly happens when staying up late. You stay up late because you're working on something fun, which offsets your sleeping pattern. Next time you try to go to bed early you can't fall asleep due to having gone up much later in the morning.
But yeah, in general this is my problem, i should go to bed BUT there's always so much more you can do before going to bed.
