Sleep plays a central role in memory consolidation - the process by which newly acquired information is stabilized and integrated into long-term memory stores. Research from institutions including Harvard Medical School and the Max Planck Institute for Human Cognitive and Brain Sciences has shown that different stages of sleep contribute to different types of memory. Slow-wave sleep, or deep sleep, appears to be particularly important for declarative memory - the kind that stores facts and events.
Rumination activates the default mode network (DMN) - the brain's self-referential processing system. This is the neural circuitry that fires when you're thinking about yourself in relation to others: your identity, your social standing, your mistakes. It's the brain asking, over and over, What does this say about me?
Neuroscientist Karen Konkoly is a lucid dreamer. When she's asleep and immersed in a dream, she knows that she is, in fact, dreaming. One of her favorite things to do during these sleep sojourns is pose personal, even existential questions - probing the mysterious terrain of her own subconscious mind. Asa researcher who studies the human mind, Konkoly has read many scientific papers positing different explanations for why humans dream - and she's made it her mission to rigorously test them.
Sleep banking is essentially extending your normal sleep hours in the nights leading up to a known period of sleep deprivation. On the face of it, it appears unlikely banking sleep could counter the decreased alertness and other cognitive decrements that we experience when deprived of sleep, or stop that strong sensation we get when our body wants sleep.
I tested AGZ's chocolate and mint flavors, which come with a frother, and you can blend the powder with water or milk, either warm or cold (although I think it tastes the best with milk, like a frothy hot cocoa). The drink doesn't taste overly sweet and has a nice, rich chocolate taste. The mix is melatonin-free, instead with adaptogens, herbs, and minerals, including magnesium, vitamin B6, L-theanine, ashwagandha, and calming herbs.
"I started getting into the frame of mind most people get sucked into. I worried, 'What's going on? Is there something wrong with me?'" he says. That fear of not being able to sleep is a phenomenon called "sleep anxiety," says Orma, who went on to become a specialist in insomnia treatment. Left untreated, that anxiety can prevent people from actually falling asleep. "The more you focus on it, the less chance you'll sleep, which then makes you more anxious. That's the cycle that spins," he says.
When I first read that, I was skeptical. But after trying it myself and digging deeper into the studies, the mechanisms started making sense. When we actively look for things to appreciate, we're essentially rewiring our brain's default mode. Instead of scanning for threats and problems (which our brains love to do), we're training it to notice the good stuff. It's like changing the channel from a disaster documentary to something that doesn't spike your cortisol.
Phones have messed up our sleep in more ways than one. Not Only do their addictive functions keep us up scrolling well past our bedtimes, but they also wake us up with jarring sounds and haptics, shocking our systems with loud sounds and frantic measures that, once the alarm is disabled, send us back to sleep, overwhelmed. Also: I biohacked my sleep with these 5 gadgets (and it worked) Smart sunrise alarm clocks have grown in popularity as an alternative to our blaring phone alarms.
So, what is the "best" sleeping position to get you there? It's a tricky (if not impossible) question to answer, since everyone's body, health, and preferences are different. But according to Jennifer Martin, PhD, spokesperson for the American Academy of Sleep Medicine and professor at the Herbert Wertheim College of Medicine at Florida International University, what's best for you hinges mostly on two factors: what position allows you to breathe easily, and what position is the most physically comfortable for your body.
