Ask HN: How do you sleep on time? (ycombinator.com)
Hello fellow HN guys, My work mostly ends around 9 to 10:00 PM. I have this hangover of spending a few hours after dinner so it ends up me being able to sleep around 12:00PM-1:00 AM which is very late. What can I do to get to sleep early?

REM Sleep as a Mechanism to Prevent Takeover of the Visual Cortex (2021) (nlm.nih.gov)
Regions of the brain maintain their territory with continuous activity: if activity slows or stops (e.g., because of blindness), the territory tends to be taken over by its neighbors.

Why some people can get away with only a little sleep every night (pbs.org)
Everyone has heard that it’s vital to get seven to nine hours of sleep a night, a recommendation repeated so often it has become gospel. Get anything less, and you are more likely to suffer from poor health in the short and long term — memory problems, metabolic issues, depression, dementia, heart disease, a weakened immune system.

Engineering Sleep (minjunes.ai)
Sleep claims a third of human life. Like water, it’s not a desire but a necessity. Sleep rules virtually every important system: brain, heart, mood, and immunity. Nature’s terms are harsh. Sleep eight hours or face mental and physical decay. Can we rewrite the terms in our favor? Can we sleep less, but still feel refreshed? I believe we can, and that now is the best time to start engineering sleep.

Could Humans Hibernate? (aeon.co)
The conventional view is that humans and other creatures around us live between periods of waking and sleeping. But it is not true. Many have mastered the art of hibernating, which allows them to spend quite a lot of their life in a mysterious state of suspended animation – sometimes more than half of it. What is hibernation, and is it something that humans might be capable of?

Association between sleep duration trajectories and successful aging; study (biomedcentral.com)
Insufficient or excessive sleep duration are associated with increased risk of individual adverse outcomes. However, it remains largely unknown whether sleep duration trajectories are associated with overall health among older adults. This study aimed to examine the association between sleep duration trajectories and successful aging.

How to Train Yourself to Go to Sleep Earlier (sleepfoundation.org)
A number of factors may impact your ability to go to sleep early. Perhaps you are not a morning person, or you have work or family obligations that keep you up late. Some sleep or mental health disorders, such as insomnia or anxiety, can make falling asleep difficult. In other instances, nighttime may be your only time to relax, and so you engage in revenge bedtime procrastination and stay up late, which then negatively impacts your next day.
