Mindfulness mediates the association between chronotype and depressive symptoms (plos.org)
Morningness-eveningness (or diurnal preference) refers to an individual’s sleep-wake behaviour (preferred bed and wake times, and times preferred for peak cognitive/physical performance). Diurnal preference impacts mental health: studies have linked a tendency towards eveningness (late chronotype) to a higher risk of major depressive disorder (MDD) [1,2].

Sleep on it: exploring the psychology of sleep amidst contemporary challenges (nature.com)
Throughout history, poets, scholars, and scientists have acknowledged the profound link between sleep and psychological well-being. The wisdom of “sleep on it”, ingrained in both Western and Eastern traditions, highlights the crucial role sleep plays in restoring and enhancing cognitive functions. In today’s fast-paced, highly-interconnected, technology-driven world, where cognitive demands are ever-growing, quality sleep has become both more vital and more elusive. This collection delves into the evolving role of sleep in maintaining psychological well-being amidst contemporary challenges.

Sleeping pills stop the brain's system for cleaning out waste (arstechnica.com)
Our bodies rely on their lymphatic system to drain excessive fluids and remove waste from tissues, feeding those back into the blood stream. It’s a complex yet efficient cleaning mechanism that works in every organ except the brain. “When cells are active, they produce waste metabolites, and this also happens in the brain.

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?
