Sleep
Sleep is a vital biological process during which the body restores and repairs tissues, consolidates memories, regulates metabolism, and clears metabolic waste from the brain, while maintaining overall physiological and cognitive homeostasis.
As described in Sleep and Health (PMC, 2005), "sleep is a naturally occurring state" necessary for recovery. Yet, in modern society, the widespread use of soft beds and mattresses stands in stark contrast to our natural design.
Human beings naturally sleep on firm surfaces such as the ground, where the body rests in its most natural alignment. Poor posture during sleep can "contribute to musculoskeletal disorders, especially back and neck pain." Soft, cushioned mattresses disrupt the alignment, causing the spine to sink and misalign, which leads to discomfort and pain.
On the other hand, the firm, supportive surface of the ground encourages the spine’s natural curvature.
“A firm sleeping surface supports the body’s natural contours, leading to better alignment."
This simple, grounded approach promotes healthy sleep and prevents strain on muscles and joints, creating a more restorative sleep cycle.
In essence, sleeping on the ground or a firm surface is not just optimal—it's the most natural way for the body to rest. By returning to this primal method we obtain more restorative rest free from the unnatural constraints of modern beds.
Sleep tips
Sleep During the Night and Arise with the Sun: Align your sleep schedule with natural daylight by sleeping at night and waking with the sun, which supports your body’s circadian rhythm.
Sleep on the Floor or a Firm Surface: To maintain correct spinal alignment and support your musculoskeletal health, sleep on a firm surface, such as the floor, which encourages natural posture and reduces strain on the back, neck, and joints.
Maintain a Consistent Sleep Schedule: Go to bed and wake up at the same time every day, even on weekends, to regulate your body’s internal clock.
Create a Relaxing Bedtime Routine: Engage in calming activities before bed, such as reading, meditation, or gentle stretching, to signal to your brain that it’s time to wind down.
Limit Screen Time Before Bed: Avoid electronic devices (phones, computers, TVs) at least 30-60 minutes before sleeping, as blue light can interfere with melatonin production.
Use Blackout Blinds and a Silk Eye Mask: Block out external light sources with blackout blinds or a silk eye mask to maintain complete darkness, which helps regulate melatonin levels and improve sleep quality.
Optimize Sleep Environment: Make sure your bedroom is cool, dark, and quiet. Consider using blackout curtains and a white noise machine or earplugs if necessary.
Avoid Stimulants and Heavy Meals: Stay away from caffeine, nicotine, and large meals close to bedtime, as they can disrupt sleep.
Manage Stress and Anxiety: Practice relaxation techniques, such as deep breathing mediation to calm your mind before bed.
