Bedtime linked with heart health:
Going to sleep between 10:00 and 11:00 pm is associated with a lower risk of developing heart disease compared to earlier or later bedtimes, according to a study published today in European Heart Journal – Digital Health, a journal of the European Society of Cardiology (ESC).1
"The body has a 24-hour internal clock, called circadian rhythm, that helps regulate physical and mental functioning," said study author Dr. David Plans of the University of Exeter, UK. "While we cannot conclude causation from our study, the results suggest that early or late bedtimes may be more likely to disrupt the body clock, with adverse consequences for cardiovascular health."
While numerous analyses have investigated the link between sleep duration and cardiovascular disease, the relationship between sleep timing and heart disease is underexplored. This study examined the association between objectively measured, rather than self-reported, sleep onset in a large sample of adults.
The study included 88,026 individuals in the UK Biobank recruited between 2006 and 2010. The average age was 61 years (range 43 to 79 years) and 58% were women. Data on sleep onset and waking up time were collected over seven days using a wrist-worn accelerometer. Participants completed demographic, lifestyle, health and physical assessments and questionnaires. They were then followed up for a new diagnosis of cardiovascular disease, which was defined as a heart attack, heart failure, chronic ischaemic heart disease, stroke, and transient ischaemic attack.
[...] He concluded: "While the findings do not show causality, sleep timing has emerged as a potential cardiac risk factor – independent of other risk factors and sleep characteristics. If our findings are confirmed in other studies, sleep timing and basic sleep hygiene could be a low-cost public health target for lowering risk of heart disease."

I can go to bed at 10:30 PM but not fall asleep until after 11:00 PM and wake up at 4:00 AM for whatever reason. Maybe fall back asleep for another hour or two yet that is not 8 hours of sleep. Does not seem very healthy to me. Everyone's body clock is not on the same time. This may work for some though.

Like me, you might have delayed sleep phase disorder (look it up). I absolutely cannot sleep before 11 and usually not before midnight. I struggle badly to get up before 8:00. If I have my eight hours of sleep, I am refreshed and ready to go... just two-three hours later than other people. I have a note from my doctor about it, and my head of school won't let my classes be scheduled before 10 am, so it works out nicely.

Another one of these "look we found something"-studies. That then goes to great lengths to backpedal their findings and in the end basically come down to nothing but vague statements that may or may not be causal.
Perhaps they should have just concluded that the best thing you can do is to get up in the morning so you get some daylight. Might be important in the UK with all the rain and fog and general "bad" weather. It might be a lot more significant then if you went to bed between 22-2300.
Technically tho they say you should fall asleep between 22-2300, not necessarily going to bed them. Which sort of makes it more problematic. Since some people take longer to go to sleep then others.
Perhaps it would have been better to just conclude that the best time to go to sleep is about 6-8h before you want to wake up.
It would seem apparent that not everyone have the same internal clock or circadian rhythm?
Also if it turns out to be so dangerous then shouldn't all forms of night activities (work or play) be forbidden? There appears to be a set of humans that are fine with being up nights or working nights and doesn't appear to take harm from it.
Me personally I go to sleep when I'm tired. I get up when I wake up and feel rested. It has nothing to do with what time the clock says it is. Clock time is only there to syncronize work and collaboration with other people. Beyond that it's pointless.
So no matter how they slept only about 3.6% developed any kind of cardiovascular disease or problems. But it was then lower if people went to sleep between said hours.
Somewhat odd considering that cardiovascular disease of some kind is more or less the leading cause of deaths globally. So sleep time probably doesn't even figure into it on a more grand scale.
https://www.who.int/news-room/fact-sheets/detail/cardiovascular-diseases-(cvds) [who.int]
That said considering the average age of their test population it shouldn't be hard to create alternative explanations for the populations sleep pattern. Most of them might have worked all their life and just got into a rhythm which explains when they go to bed and when they get up.
Here is something radical. The optimum time to go to sleep is about 6-8 hours before you want to wake up. Add another hour or two also if you plan on being at work at a specific time. That is when people tend to go to bed. To sync up with the coming workday.
At least they acknowledge the importance of daylight. So in England then, since that was where this took place. Perhaps it's important to get up in the morning so you'll see some daylight at all, at least during certain times of the year. Not only that but also the general shit weather the island have with all that rain.

Also, no empirical data here, but I was born at 11:22 PM, and was a night owl for years. The mantra used to be: "Rather be up with the sun than get up with it."
In the service (and working the graveyard shift), I'd get to sleep around 2PM, in time to be back up at 10:30 for the "day's" work.
(It also messed up eating, as all the chow hall had when I got off was eggs, bacon, regular breakfast stuff. Since "breakfast" literally means "breaking your fast", I just started calling every meal by that name.)
These days I'm more of a daytime person, but still no trouble pulling an all-nighter when needed.
Generally, six hours from whenever sleep starts is enough.
