the science of sleep

Sleep is the Strongest Legal Performance Enhancer in the World.

Stop sleeping

on sleep.

Imagine unlocking superior performance, heightened focus, accelerated learning, weight loss, inflammation resistance, the ability to navigate challenges and traumas, and even flushing out brain toxins—all with your eyes closed.

Well, actually... you can. Welcome to the transformative power of quality sleep.

Body & Hormones

Portal isn’t just about more hours; it’s about better hours. Users with health trackers like Whoop, Oura, or Apple Watch consistently report falling asleep faster and spending more time in that crucial deep sleep stage that your body needs to repair and rejuvenate.

Did you know that 70% of Human Growth Hormone production occurs during Deep (Slow Wave) Sleep? This hormone plays a crucial role in cell and tissue repair.

Statistics reveal that sleep-deprived athletes are 60% more likely to get injured compared to those who get 8 hours of sleep or more.

This higher injury risk is largely due to the breakdown of stability muscles during inadequate sleep.

Quality sleep is essential for regulating leptin and ghrelin, two key hormones that control hunger and fullness.

Sleep-deprived individuals have suppressed leptin and increased ghrelin levels, leading to an extra 200–300 calorie intake per day and cravings for high-carb, sugary foods. When deprived of sleep, dieters tend to lose 70% of their weight from lean muscle mass instead of fat.

This happens because the body holds onto fat cells for essential energy. Additionally, sleep deficit impairs insulin response, increasing the risk of hyperglycemia and diabetes.

Insufficient sleep significantly impacts heart health. Sleep helps regulate stress hormones like cortisol and reduces the risk of cardiovascular disease.

Adults who sleep less than 6 hours per night have a 200% higher risk of heart attack or stroke due to the effects of sleep deprivation on heart rate and blood pressure.

Studies from countries that observe Daylight Saving Time reveal a 21% decrease in heart attacks on days with an extra hour of sleep and a 24% increase on days when an hour is lost.

Sleep is crucial for a strong immune system. During sleep, your body produces and releases cytokines, proteins that target infection and inflammation, effectively creating an immune response.

Chronic sleep deprivation can reduce the production of these protective cytokines, making you more susceptible to illnesses and infections.

Ever heard the saying "sleep on a problem"? It's based on science. Sleep enhances problem-solving skills by merging past memories with current challenges.

Research shows significant improvement in word recall for those who sleep before a test, as the brain compartmentalizes information during sleep, fostering better learning and retention.

The Glymphathic system is the brain's waste disposal mechanism, effectively eliminating harmful substances. During sleep, its activity increases tenfold, showing heightened efficiency in purging compounds like beta-amyloids, which are linked to Alzheimer's disease.

Brain scans of sleep-deprived individuals reveal a 60% surge in amygdala activity, the brain region associated with negative emotions.

Over time, this heightened activity raises the risk of anxiety disorders, depression, and social isolation.

REM sleep helps you process emotional information and inputs from the day, allowing you to work through them and maintain mental health.

Sleep, particularly REM sleep, plays a vital role in consolidating memories and knowledge. It acts as a conduit, transferring information from the hippocampus (short-term memory) to the cerebral cortex (long-term memory).

the stages of sleep

Your body’s natural daily rhythms are regulated by structures in the brain that help determine when you fall asleep and wake up.

People progress through a series of distinct physiological stages during sleep. Each stage serves an important purpose in keeping your brain and body healthy. During the night, these stages of quiet sleep alternate with periods of REM (dreaming) sleep.

Quiet sleep helps restore the body, while REM sleep restores the mind and is crucial for learning and memory.

stage n1

In making the transition from wakefulness into light sleep, you spend about five minutes in stage N1 sleep. Body temperature begins to drop, muscles relax, and eyes often move slowly from side to side. People in stage N1 sleep lose awareness of their surroundings but are easily jarred awake.

stage n2

This first stage of true sleep lasts 10 to 25 minutes. Your eyes are still, and your heart rate and breathing are slower than when awake. Large, slow brain waves intermingle with brief bursts of activity called sleep spindles. You spend about half the night in stage N2 sleep.

stage n3 (Deep Sleep/ Slow-Wave Sleep)

Large, slow brain waves called delta waves surface, and you enter deep sleep. Breathing becomes more regular, blood pressure falls, and the pulse slows. The brain is less responsive to external stimuli, making it difficult to wake the sleeper. Deep sleep is a time for your body to renew and repair itself. Blood flow is directed less toward your brain, which cools measurably. At the beginning of this stage, the pituitary gland releases a pulse of growth hormone that stimulates tissue growth and muscle repair.

Dreaming (REM) Sleep

Dreaming occurs during REM (rapid eye movement) sleep, an “active brain in a paralyzed body” state where your brain races and your eyes move rapidly behind closed lids while your body remains still. REM sleep is believed to restore your mind by clearing out irrelevant information. Studies show REM sleep enhances learning and memory, with sleep deprivation leading to cognitive decline. Thus, the quality and time spent in REM sleep are crucial for cognitive function.
