»Nobody Wants to Admit What Modern Life Is Doing to Us«
„Why does waking up for work feel so unnatural? The 9–5, social jetlag and modern work culture may be forcing your body to sleep on a schedule it never chose.
From night owls and chronotypes to segmented sleep, burnout and the eight-hour workday, this explores how work took control of our sleep.
Maybe you don't have a sleep problem. Maybe you have a schedule problem — and escaping wage slavery starts with understanding who really owns your time.“

"Sleeping directly on the earth with no or only natural padding is the gold standard – equivalent to barefoot walking in nature and still a luxury for some cultures around the world and a few hard-core westerners. The closest most people will come in their daily lives, however, will be sleeping on hard flat floors with minimal non-natural padding. All the same, the benefits over sleeping on a modern mattress with a pillow are significant. The forces of a minimally padded floor provide a variety of loads to your body’s tissue that don’t occur on soft-casting mattresses, because you move more without external resistance inherent in a body-conforming mattress. This results in greater ranges of motion for joints that are underused at best, or completely immobile on a mattress. The pressure of a hard surface provides a passive massage to your muscles each time you move, thereby causing mechanotransduction of your cells that facilitates circulation, electricity, and waste removal. In addition to facilitating your body’s natural geometry (positioning of your parts to each other and to the floor) and providing a nightly tissue regenerating massage, sleeping on the floor allows gravity to traction those parts of you, like your neck, helping to restore your muscles to their optimal resting length. Just as sitting on the floor provides yin yoga style benefits of naturally stretching and tractioning muscles and connective tissues in your hips, sleeping on an unyielding surface is where natural neck stretching occurs. An additional benefit of floor sleeping is that it gives you at least one opportunity, and probably more, to get down onto the floor and up again.
If you go from sleeping on a bed one night to sleeping on the floor the next, without a transitional ramping down period, it’s going to be quite uncomfortable and may undermine your success. This could happen not because the floor is too hard, but because your body is “out of shape” for floor sleeping. You wouldn’t start a running program by doing a half-marathon. You would train by slowly increasing your miles, speed, and frequency, with plenty of rest days. Same with moving to the floor. If you exceed the boundaries of your tissues’ ability to adapt; and create loads that are more than what you body is used to, you may suffer. By transitioning slowly and systematically towards progressively more minimal sleeping surfaces, you will gradually load your tissues so that they can adapt to your new sleeping routine.
Katy Bowman writes about transitioning away from a mattress. I’ve distilled her suggestions, and added a few of my own. You’ve been sleeping on a mattress all of your life, so take time – weeks, months – to transition to the floor.
Try these steps:
- remove pillow topper from your current mattress
- place mattress directly on ground (yes, removing box springs changes the * forces of a mattress)
- replace mattress with futon
- replace futon with a thick rug/carpeting and some blankets
- remove the blankets one at a time
- replace carpeting with Tatami mat (Japanese sleeping mat)
You can follow a similar transition pattern for your pillow, going from thick and dense to thin and feathery to a folded towel, etc."

"Continuous sleep is a modern habit, not an evolutionary constant, which helps explain why many of us still wake at 3 am and wonder if something's wrong. It might help to know that this is a deeply human experience.
For most of human history, a continuous eight-hour snooze was not the norm. Instead, people commonly slept in two shifts each night, often called a "first sleep" and "second sleep."
