In today's fast-paced world, it's easy to glorify the “work hard, play hard” mentality, where sleep is often considered a luxury rather than a necessity. I used to be a staunch believer in the idea that I could "sleep when I die." My days were filled with hard work, intense play, and rigorous 5 AM workouts. To me, health was all about fitness and nutrition, with little regard for the value of a good night’s rest.
Growing up with parents who were both physicians, I inherited some of their beliefs about sleep. They went through medical residency in an era before there were protections against the inhumane hours the system required of young doctors. They often told me that we could train our bodies not to need much sleep, and I believed them.
But everything changed when I read Dr. Matthew Walker’s book, "Why We Sleep." What I "knew" was completely debunked. Walker's research and insights made it clear that sleep is not just a passive state but a critical function that impacts every aspect of our health and well-being.
Initially, I was skeptical. After all, I had been managing fine with minimal sleep for years. Or so I thought. As I delved into Walker's findings, I realized the depth of my misconceptions. He explained how insufficient sleep is linked to serious health issues like dementia and early death, the vital role of REM sleep in cognitive function and emotional regulation, and the long-term consequences of chronic sleep deprivation.
Walker’s book highlighted alarming statistics: individuals who routinely sleep less than six or seven hours a night are at significantly increased risk of developing diseases like Alzheimer’s, cardiovascular disease, stroke, and diabetes. The connection between lack of sleep and early death was particularly striking. It became clear that sacrificing sleep was not a sustainable or healthy choice.
Arthur Schopenhauer’s wisdom echoed in my mind as I read: “It might be said that sleep is the interest we have to pay on the capital which is called in at death; and the higher the rate of interest and the more regularly it is paid, the further the date of redemption is postponed.” Sure, I could wait to sleep until I was dead. And if I did? That death would likely come much sooner than it would otherwise, and certainly sooner than I wanted.
Realizing the error of my ways, I decided to make a change. I began to prioritize sleep, adopting new habits and routines to ensure I got the rest I needed. Dr. Walker’s QQRT formula became my guide. The QQRT formula stands for quality, quantity, regularity, and timing, which are key components in improving sleep hygiene.
Quality: I focused on creating a restful and undisturbed sleep environment. This meant investing in a comfortable mattress, using blackout curtains to eliminate light, wearing and eye mask and ear plugs, and maintaining a cool room temperature, including using mattress cooling technology.
Quantity: I aimed for the recommended 7-9 hours of sleep per night. This required me to adjust my schedule and make sleep a non-negotiable part of my routine.
Regularity: Consistency became crucial. I made an effort to go to bed and wake up at the same time every day, even on weekends, to stabilize my internal clock. I did not previously realize the dangers inherent in the “social jetlag” I subjected myself to every weekend.
Timing: Aligning my sleep patterns with natural circadian rhythms meant for me as an early riser avoiding late nights and ensuring I got to bed at a reasonable hour.
Implementing these changes was transformative. I noticed significant improvements in my mood, focus, and overall physical health. The benefits of good sleep were undeniable. My energy levels soared, my workouts became more effective, and I felt more present and engaged in my daily activities.
The journey from undervaluing sleep to recognizing its importance taught me valuable lessons. It’s crucial to prioritize sleep and not postpone necessary rest for the sake of work or other commitments. Everything else can wait. Building a support system that can offer objective advice and ensure we act in our best interests is also essential. Recognizing when personal biases are clouding judgment and being willing to reevaluate habits is vital.
While it’s easy to dismiss the importance of sleep in favor of productivity and other pursuits, understanding and prioritizing sleep is essential for a healthy, balanced life. Reflecting on Schopenhauer’s wisdom, it’s clear that taking care of ourselves starts with a good night’s rest. Our days don’t end with sleep, but rather they start with how we slept the night before. So, let’s reevaluate our sleep habits and make the necessary changes for better health and well-being.
