The Power of the Sleep Cycle: the Clock of Nature and its Impact on Everyday Life
Author: Silver Laus (CEO of Shroomwell)
The sleep cycle, in other words, the rhythm of the circadian rhythm often referred to as our body's internal clock, is not just a biological buzzword; it is a complex symphony of processes that defines our daily existence. Understanding it and aligning with it can unlock unparalleled health, productivity and well-being.
The Sleep Cycle Concept
The core of the sleep cycle is our body's internal 24-hour clock, influenced primarily by signals of light and darkness. Morning (yellowish) light triggers our metabolism and alertness by producing cortisol. As daylight (bluish tint) continues, our body temperature increases, peaking in the late afternoon - often achieving optimal muscle and cognitive function. As darkness falls, melatonin production kicks in, guiding us towards rest and recovery.
The average person is recommended to get 8 hours of sleep in one day. It is also important to have a bedtime and wake-up time that correlates with the normal 24-hour sleep cycle. Depending on the individual, this varies between about 21:30 and 23:30 and between 5:30 and 7:30.
It is important to keep this in mind, as it is also the time of the REM sleep cycle and the deep sleep cycle, which in turn strongly influence the cycles of information storage, retrieval, and emotional functioning.
Shifting or shortening the bedtime does not shift either REM or deep sleep stages, so we are already breaking the cycle and therefore less able to do so.
Synergy of the Sleep Cycle: the Benefits of Being Consistent
By synchronising with the sleep cycle, this leads to peak cognitive performance, facilitating focus, judgement and productivity.
2. Optimal Hormonal Balance. Recognising this can lead to better sleep quality and stress regulation.
Regular sleep patterns that are in tune with our sleep cycle can protect against mood disorders such as depression.
4. Stronger Immune System: Our immune system is directly linked to our lifestyle, our surroundings and our everyday decisions. Adequate and stable sleep is the foundation of our immune system.

Our daily activities, from eating to brainstorming, are closely linked to this rhythm:
1. Digestion and Metabolism: Our metabolic activity, which is linked to our sleep cycle, peaks at noon. Late-night eating and snacking can put a strain on our system, thus disrupting our sleep cycle, which in turn increases the risk of weight gain.
2. Cognitive Abilities.
Examples from Life itself
Studies show that the damage to the economy caused by sleep deprivation is significant. In the US alone, it is estimated to cost the economy around $140 billion a year, and the trend is increasing. But this does not include the benefits of increased capacity if everyone could operate at their maximum.
It has been proven through various studies that 30min of lost sleep (or sleep quality!) alone reduces cognitive and focusing ability by about 10%. 60 min already reduces cognitive and focusing ability by about 15-20%.
Converting this knowledge into our daily lives, this essentially means that by taking care of a quality sleep rhythm, we could not only earn 10-20% more income, but also be able to achieve more in other areas of our daily lives, being happier, healthier and more vital.
Risks of Ignoring the Natural Clock
Ignoring the sleep cycle, whether deliberately or due to the busy-ness of modern life, can have profound negative effects:
1. Sleep problems: people with unpredictable schedules, such as shift workers or frequent travellers, often struggle with conditions such as insomnia or sleep apnoea. The effects aren't just fatigue; chronic sleep deprivation can lead to serious health problems such as heart disease and weakened immune systems.
2. Weight gain and metabolic disorders. In the long term, this can increase the risk of obesity, diabetes and other metabolic syndromes.
3. Reduced immune function. It also weakens our immune system, making us more susceptible to common infections and possibly reducing our ability to fight off disease.
4. Mental Health Decline. There is growing evidence that chronic disorders can lead to serious conditions such as depression, anxiety and even bipolar disorder.
5. Cardiac load: Constant shuffling in our sleep-wake cycle is linked to elevated blood pressure and higher cholesterol levels, which are precursors to heart disease.
6. Cognitive Abnormalities: Over time, a constant disregard for our natural rhythms can lead to memory problems, reduced alertness and reduced cognitive abilities. Although not fully proven, sleep problems are thought to be one of the catalysts for Alzheimer's and Parkinson's.
7. Hormonal Disorders. Disturbances can lead to conditions such as thyroid imbalances, adrenal fatigue and even fertility problems.
Finally, our sleep cycle is not just an abstract biological concept; it is an evolutionary tool intimately linked to our physiology. It determines our optimal productive hours and controls many functions of our body. In our technology-centric, always-on age, being in tune with this rhythm is more than desirable - it is the foundation of good health. Whether you're an athlete, an executive or someone navigating the challenges of modern life, understanding and respecting this internal clock is an unsurpassed bio-hack for long-term health and peak performance.
