The Forgotten Power of Rest

In a world that prizes productivity, the value of rest often goes unnoticed or is downright forgotten. Yet, rest is not just about sleep—it's an essential pillar of health, as important as nutrition or exercise. Rest plays a crucial role in balancing your hormones, supporting immune function, aiding digestion, promoting detoxification, ensuring energy production, and regulating the nervous system. Whether you're a man or a woman, understanding the biological importance of rest can help you transform your health in surprising ways.

​The Biological Impact of Rest

Hormonal Balance:  When you're sleep-deprived or running on empty, your body produces more cortisol, which is known as the stress hormone. Elevated cortisol disrupts the production of other hormones, such as testosterone in men and estrogen in women, which can lead to mood swings, weight gain, and decreased libido. Inadequate rest also inhibits the production of growth hormone, essential for tissue repair and muscle development. In women, imbalances in cortisol can lead to more severe PMS or menopausal symptoms.

Rest Tactic #1: Prioritize 7-9 hours of sleep per night. Create a wind-down routine free of screens and artificial light to encourage natural melatonin production, which helps regulate your sleep-wake cycle.

Immune System Function:  A well-rested body is more resilient against infections. Lack of rest compromises your immune response, reducing your ability to fight off pathogens. One study showed that people who sleep less than 7 hours a night are nearly three times more likely to catch a cold than those who sleep 8 hours or more. Rest is when your body regenerates immune cells and produces cytokines, proteins that target infection and inflammation.

Rest Tactic #2: Incorporate short naps (15-30 minutes) during the day to boost immune function. Research shows that even brief naps can reverse the hormonal impact of a poor night’s sleep. Naps are really effective and are something we have been missing from American culture. It's been shown that three 30 minutes naps per week can reduce your risk of heart disease by over 30%!

Digestive Health: Rest, particularly sleep, is crucial for optimal digestion. The parasympathetic nervous system, responsible for "rest and digest" functions, becomes more active when you rest. When sleep is sacrificed, digestion slows down, leading to issues like bloating, indigestion, and even increased risk of conditions such as IBS or acid reflux.

Rest Tactic #3:  Try mindfulness techniques such as deep breathing or meditation to activate your parasympathetic nervous system. Be in a relaxed state after meals for 10-15 minutes to support digestion and prevent digestive discomfort.  You could also take a leisurely walk around the neighborhood after eating. 

Detoxification:  Your liver, kidneys, and lymphatic system are at their most active in detoxifying your body while you rest. During sleep, your brain also clears out toxins through the glymphatic system. If you cut sleep short, this natural detoxification process is interrupted, which may lead to brain fog, headaches, and sluggishness. This can also lead to an overburdening of the liver as it is unable to fully clear toxins from the day, leading to an excess buildup and potential spillover into the bloodstream. 

Rest Tactic #4: Ensure you get deep sleep stages (particularly REM and slow-wave sleep - more on that later) by avoiding alcohol and heavy meals close to bedtime. This will allow your body’s detoxification processes to function optimally. Heavy meals and alcohol before bed can also interfere with your blood sugar levels and may create an increase in cortisol production, which damages your sleep quality as well. 

Energy Production: Chronic fatigue is one of the most telling signs that your body is starved for rest. Mitochondria, the powerhouses of your cells, need downtime to repair and regenerate. Sleep deprivation can reduce mitochondrial function, leading to poor energy production, exhaustion, and even metabolic disorders. The way the body produces energy is extremely complicated and just reaching for some caffeine will not solve the long-term problem of a lack of quality rest (in fact, it will only make things worse!).

Rest Tactic #5: Practice "active rest" during the day—take regular breaks, go for a walk, or do light stretching to refresh your mitochondria and promote steady energy levels throughout the day. Stretching needs to be a part of your every day routine anyways. It's especially needed the older we get! 

Nervous System Regulation:  Your autonomic nervous system (ANS) consists of two main components: the sympathetic (fight or flight) and parasympathetic (rest and digest) systems. Rest helps rebalance the ANS, ensuring you don’t stay in constant "fight or flight" mode. Chronic stress and lack of rest can lead to burnout, anxiety, and cardiovascular issues. It's important to understand that the body cannot be in both a sympathetic and parasympathetic state. The body will ALWAYS prioritize the sympathetic, aka fight or flight, mode as long as there's a perceived or real external threat. If you think something is stressful, so does your mind and body! 

Rest Tactic #6: Try grounding techniques such as walking barefoot on grass or using a grounding mat, as these have been shown to help regulate the nervous system. There are also some grounding bed sheets that seem to work well. I haven't tried them yet, but it's on my list! 

Now let's dive into one last topic when it comes to quality rest: REM Sleep

REM Sleep: The Critical Stage for Restoration

REM sleep (Rapid Eye Movement) is one of the most important phases of the sleep cycle. It’s during this stage that your brain becomes highly active, consolidating memories, processing emotions, and supporting neurological health. REM sleep also plays a crucial role in physical restoration, regulating mood, and fostering creativity. Although REM makes up about 20-25% of your total sleep time, it is the most vital phase for cognitive and emotional functions.

Overview of REM Sleep

REM sleep typically occurs about 90 minutes after falling asleep, and the duration of REM periods increases throughout the night. During REM, the brain activity is similar to when you're awake, but your body is in a state of temporary paralysis (except for essential functions like breathing and eye movement).
It is a critical time for mental health, problem-solving, and emotional processing. The average adult spends approximately 90-120 minutes in REM sleep each night.

Interesting REM Sleep Statistics

Memory Boost: Studies show that REM sleep enhances memory consolidation, especially for complex tasks. People deprived of REM sleep show 30% slower reaction times and memory recall compared to those who get adequate REM.

Emotional Health: REM sleep is essential for emotional regulation. Research from the Journal of Neuroscience experts have found that people who experience REM sleep deprivation are 60% more likely to overreact emotionally to situations.

Dreams and Creativity: The creative problem-solving processes during REM sleep improve by 32% after a good night’s rest, according to a study published in Nature.

Brain Detoxification: During REM sleep, the glymphatic system (your brain’s waste disposal system) is highly active, clearing out toxic proteins like beta-amyloid, which are linked to Alzheimer’s disease.

Tactics to Maximize REM Sleep

#1 Prioritize a Full Night’s Sleep: Since REM sleep periods lengthen as the night progresses, ensuring 7-9 hours of sleep is key. If you routinely cut your sleep short, you’ll miss out on the most substantial REM stages that occur later in the sleep cycle.

#2 Maintain a Consistent Sleep Schedule: Going to bed and waking up at the same time every day helps regulate your body’s internal clock, promoting a stable sleep pattern and ensuring you experience adequate REM sleep. You also need to consider your last meal of the day when it comes to this schedule. Aim for your last meal to be at least 3 hours before bedtime. 

#3 Create a Relaxing Pre-Bedtime Routine:  Wind down with calming activities like reading, meditation, or light stretching. Avoid screens and bright lights at least 1 hour before bed to support melatonin production and optimize sleep quality, including REM.

#4 Limit Alcohol and Caffeine:  Alcohol might help you fall asleep faster, but it disrupts REM sleep. Caffeine can stay in your system for hours, reducing both the quantity and quality of REM. Try to avoid alcohol and caffeine in the late afternoon and evening. Alcohol can also contain sugar, which can lead to a drop in blood sugar as you sleep. To maintain balance, the body will raise blood sugar levels, which can also disrupt sleep. 

#5 Ensure a Sleep-Friendly Environment: Keep your bedroom cool (between 60-67°F), dark, and quiet. A comfortable sleep environment promotes better overall sleep, including REM phases. Consider using blackout curtains, white noise machines, or earplugs if needed.

#6 Address Stress: Chronic stress and anxiety can significantly reduce REM sleep. Consider adopting stress-relieving habits such as yoga, journaling, or mindfulness meditation, which can help calm the nervous system and increase REM sleep quality.  I'd also add a complete mineral supplement to your nighttime routine. These can help put you into a more relaxed state, both physically and mentally.  Also, I would take magnesium every night to help improve sleep quality and reduce stress. 

Some interesting sleep statistics: 
It's amazing how much more effective we can be when we get the right amount of rest. Check out some of these powerful and surprising facts about rest!

Lack of Sleep and Longevity: Studies show that chronic sleep deprivation (less than 6 hours per night) can reduce life expectancy by up to 12 years.

Productivity and Sleep: One study showed that people who slept 7-8 hours were 20% more productive than those who didn’t, proving that rest fuels not just health but also success.

Nap Benefits: A NASA study found that a 26-minute nap improved pilot performance by 34% and alertness by 54%, highlighting how even short breaks during the day can refresh mental capacity.

Immunity and Rest: Sleep-deprived individuals were found to have 70% fewer natural killer cells, a key part of your immune defense system.

Rest and Memory: Rest boosts memory consolidation and cognitive function. Without adequate rest, you are 40% less effective at forming new memories.

Conclusion
Getting proper rest isn't a luxury—it's a vital part of health maintenance and optimization. The effects of rest are far reaching and influence every system in the body, from hormones to immunity, digestion to detoxification, and energy production to nervous system regulation. While our modern world has many amazing things to offer, it also can lead to some unwanted "side effects". One of the biggest issues, in my opinion, is that we can always be "plugged in". Getting restorative rest in today's world must be something done intentionally. I challenge you to try and give yourself the best rest possible for the next 30 days. Pay attention to how different you feel and act. It could drastically change your life for the better!
