Middle-of-the-night insomnia affects many people, often due to biological reasons, and can be managed with specific strategies.
Due to alcohol being a depressant substance, this means that it slows down your central nervous system by calming the neurotransmitters that keep you alert. Alcohol can behave the same way sedatives do, by fixating on the two neurotransmitters in your brain known as gamma-aminobutyric acid (GABA) and glutamate.
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.
Most of the carbohydrates in these foods - as well as most of the calories - come from starch, of which there are two types: hard-to-digest amylose and easily digested amylopectin. The latter is processed quickly and spikes blood sugar. The former is processed slowly and moderates blood sugar.
I used to brag about how little sleep I got. It felt like a superpower: I could sleep just three or four hours a night, and still operate at a very high level. That helped me get ahead early on. As a teen, I bused tables and sold firewood. By the time I was 19, I bought a house (which was possible because it was the subprime mortgage days). Having a mortgage gave me real responsibility at a young age.
"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.
As hormones shift during the transition into menopause, many women notice that their energy levels react differently to carbohydrates than they did in earlier years. Muscle mass tends to decline with age when strength training is absent from a routine. Because muscle mass determines how the body uses glucose, maintaining it through regular activity may support steadier daily energy.
Rather than simply extending the fasting window or cutting more calories, the intervention group was simply asked to finish eating at least three hours before their usual bedtime. That meant no snacking while watching TV after dinner and no "just one more bite" at 10 p.m. (my personal downfall). This relatively simple intervention ensured that the overnight fast overlapped with the body's natural sleep-wake rhythm.
Why would you do that? It's a way to remove distraction, calm your nervous system and practise mindfulness. And get clean. Yes, you also get clean. But this is more about finding those small, intentional moments that release you from the cares of your day. It sounds like an accident waiting to happen. You don't have to shower in complete darkness just in dim light, even by candlelight.
It's normal to feel sluggish during the winter. Cold temperatures and fewer hours of sunlight can mean less time outdoors and more time staring at our screens. For some people, these cold-weather habits may contribute to a sleep disruption, known as winter insomnia. This isn't a clinical condition, but it might begin or worsen during the winter months.
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.
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.
