6 Key Concepts
Temperature Minimum
This is the lowest body temperature experienced in a 24-hour cycle, occurring approximately two hours before one's average wake-up time. Knowing this point helps in timing activities like focused work, as optimal cognition often occurs a few hours after this minimum.
Optic Flow
This refers to the visual experience of images passing by the eyes during forward motion, such as walking, running, or biking. Experiencing optic flow has a powerful effect on the nervous system, specifically reducing activity in the amygdala, a brain structure involved in anxiety and fear.
Adenosine Blocker
Caffeine acts as an adenosine blocker by competitively binding to adenosine receptors in the brain, preventing adenosine from causing feelings of sleepiness. Delaying caffeine intake allows natural adenosine levels to drop, optimizing the caffeine's effect for sustained alertness without a crash.
Ultradian Cycles
These are approximately 90-minute cycles that the brain undergoes throughout the day and night, during which alertness levels fluctuate. Structuring focused work into 90-minute bouts aligns with these natural cycles, allowing for periods of high concentration followed by brief dips.
Arteriovenous Anastomoses (AVAs)
These are specialized blood vessels located in the palms, upper half of the face, and bottoms of the feet. They play a crucial role in cooling the body by allowing heat to dissipate rapidly, which is important for facilitating the drop in body temperature necessary for falling and staying asleep.
GABA
GABA (gamma-aminobutyric acid) is an inhibitory neurotransmitter in the brain that helps to reduce neural activity. Promoting GABA release, for instance through certain magnesium forms, can help shut off the forebrain, reducing rumination and planning, thereby aiding in the transition to sleep.
10 Questions Answered
Sunlight exposure early in the day stimulates specific neurons in the eye (melanopsin cells) that signal to the brain that it's daytime, promoting alertness, setting the body's circadian rhythm, and initiating crucial biological cascades for overall health.
Delaying caffeine 90-120 minutes after waking prevents a late afternoon crash by allowing natural adenosine levels to drop, ensuring caffeine blocks adenosine receptors when levels are higher, providing a more consistent energy arc throughout the day.
Fasting increases levels of adrenaline (epinephrine) in the brain and body, which, when in an optimal range, provides a heightened sense of focus and enhances the ability to encode and retain information.
Positioning your screen at or slightly above eye level keeps your eyes directed upward, which creates a state of heightened alertness by leveraging the brainstem neurons that control eye muscles and eyelids.
Physical movement, especially a combination of strength/hypertrophy and endurance work, supports brain health by promoting brain-derived neurotrophic factor (BDNF) and regulating inflammatory cytokines, provided workouts are of appropriate duration and intensity.
Eating a large volume of food can cause lethargy by diverting blood to the gut. Lower carbohydrate intake at lunch can support alertness, while sufficient omega-3 fatty acids (EPA) can support healthy mood and act as an antidepressant.
Viewing sunlight in the afternoon lowers the sensitivity of your retina in the late evening, buffering against the negative effects of bright light at night and supporting natural melatonin production for easier sleep onset.
A dinner rich in starchy carbohydrates helps increase serotonin in the brain, which is necessary for the transition to sleep and promotes a sense of calm and relaxation.
Accelerating the natural drop in body temperature needed for sleep can be achieved by taking a hot bath, shower, or sauna before bed, as the body then engages cooling mechanisms more quickly after exiting.
If waking is due to pushing sleep too late, try going to bed earlier. If you need to use the restroom, keep lights dim and return to bed as quickly as possible to minimize disruption to your sleep cycle.
32 Actionable Insights
1. Morning Sunlight Exposure
Get outside for a 10-15 minute walk first thing in the morning to get sunlight in your eyes, even on cloudy days. This is vital for mental and physical health, stimulating neurons that signal it’s daytime, promoting alertness, and timing a healthy cortisol pulse.
2. Morning Walk for Amygdala Reduction
Take a walk (forward ambulation) first thing in the morning to generate optic flow (visual images passing by). This powerfully quiets or reduces neural activity in the amygdala, thereby lowering anxiety and promoting an alert but calm state.
3. Hydrate with Electrolytes Upon Waking
Drink water with about half a teaspoon of sea salt early in the day, before starting any work, to ensure proper hydration. Neurons require sodium, magnesium, and potassium for function, and we tend to be dehydrated at night.
4. Delay Caffeine Intake
Purposely delay caffeine intake to 90-120 minutes after waking. This prevents a late afternoon caffeine crash by allowing adenosine levels to naturally clear before caffeine blocks its receptors, ensuring a consistent energy arc throughout the day.
5. Optimize Sleep Environment Temperature
Ensure your sleeping environment’s temperature is correct, as your body temperature needs to drop by 1-3 degrees to fall and stay deeply asleep, and increase by 1-3 degrees to wake up refreshed.
6. Time Deep Work by Temperature Minimum
Identify your temperature minimum (approximately two hours before your average wake-up time) and aim to start your best, most focused work 4-6 hours after this minimum. This leverages your body’s natural temperature rise to support cognitive focus.
7. View Afternoon Light for Sleep
Get outside in the afternoon or early evening (around 4 PM-ish) for 10-30 minutes without sunglasses to view the sun. This lowers the sensitivity of your retina in the late evening, buffering against the negative effects of bright light at night and supporting natural melatonin production.
8. Practice Intermittent Fasting for Focus
Consider fasting until about 11 AM or 12 PM. Fasting increases levels of adrenaline (epinephrine) in the brain and body, which, in optimal ranges, enhances learning and focus.
9. Elevate Screen for Alertness
Position your computer screen or tablet at least at eye level, and ideally slightly higher. Looking down tends to decrease alertness and increase sleepiness, while looking upward creates a state of heightened alertness.
10. Work in 90-Minute Ultradian Cycles
Structure your work into 90-minute blocks, understanding that the brain cycles between alertness and less alertness every 90 minutes. Set a timer and aim for a strong bout of work within this period.
11. Eliminate Phone Distractions During Deep Work
Turn your phone completely off (not just airplane mode) during dedicated work blocks. This prevents distractions and helps you achieve a state of deep focus or ’tunnel of quality work'.
12. Use Low-Level White Noise for Focus
Play low-level white noise during work sessions. White noise, which contains all frequencies of sound mixed randomly, can put the brain into a state optimal for learning and workflow.
13. Prioritize Morning Deep Work Block
Dedicate a morning 90-minute work block to your hardest or most important cognitive task. Positioning this early in the day and structuring other protocols around it ensures it happens with high efficiency.
14. Engage in Physical Exercise After Work
After a bout of focused work, force yourself to do some form of physical exercise. This supports brain health, brain function, organ health, and bodily function in general.
15. Keep Workouts Under an Hour
Aim to keep hard workouts under an hour. Exercising for longer than an hour can be detrimental due to excessive cortisol elevation, which is not desirable throughout the day.
16. Combine Strength and Endurance Training
Incorporate both strength/hypertrophy and endurance training across the week, rather than necessarily in the same workout. This combination is immensely beneficial for producing brain-derived neurotrophic factor and regulating inflammatory cytokines.
17. Apply 80/20 Rule to Resistance Training
Structure your resistance training so that approximately 80% of it does not go to failure, while the remaining 20% can be higher intensity training to failure. This optimizes muscle growth and strength without overstressing the body.
18. Apply 80/20 Rule to Endurance Training
For endurance work, focus on pushing past the lactate threshold (experiencing the ‘burn’) for about 20% of your training. This supports brain health and function by generating lactate, which is a fuel source for the brain.
19. Eat Smaller Meals for Cognitive Function
Avoid ingesting large volumes of food at any meal. Large meals divert blood to the gut, leading to lethargy and less blood flow to the brain, which can impair thinking ability.
20. Prioritize Protein/Vegetables for Lunch
For lunch, emphasize slightly lower or low carbohydrate intake, focusing on protein (e.g., meat, chicken, salmon) and vegetables. This supports alertness by leveraging adrenaline and dopamine, as starches can cause serotonin release and sleepiness.
21. Ingest Sufficient Omega-3s for Mood
Ingest at least 1,000 milligrams per day of the EPA form of essential fatty acid. Sufficient omega-3s support healthy mood and can be as effective as prescription antidepressants in relieving depression.
22. Walk After Midday Meal
Take a brief walk of 5-30 minutes after your midday meal. This accelerates metabolism, improves nutrient utilization, provides optic flow, and gives your brain more information about light and time of day.
23. Eat Starchy Carbohydrates for Dinner
Comprise your dinner largely of starchy carbohydrates and some protein. This increases serotonin in the brain, which is necessary for the transition to and maintenance of deep sleep, and helps replenish glycogen stores.
24. Avoid Serotonin Sleep Supplements
Avoid supplementing directly with serotonin or its precursors (like 5-HTP or tryptophan) in the evening or at night. This can disrupt sleep architecture, causing rapid sleep onset, deep sleep for a few hours, then difficulty falling back asleep.
25. Take Element for Hydration/Electrolytes
Dissolve one packet of Element (an electrolyte drink with sodium, magnesium, and potassium, but no sugar) in 16-32 ounces of water upon waking and during physical exercise. This ensures adequate hydration and electrolyte intake, critical for optimal brain and body function.
26. Take Hot Bath/Shower/Sauna Before Bed
Use hot baths, hot showers, or a sauna before bed. Counter-intuitively, getting out of a hot environment triggers cooling mechanisms in your body, accelerating the necessary drop in temperature for easier sleep onset.
27. Keep Bedroom Dark and Cool
Ensure your bedroom is very dark and cool. A cool room aids in falling and staying asleep by allowing the body to regulate its temperature more effectively, especially during sleep phases where movement is possible for cooling.
28. Supplement for Sleep Transition
Consider supplementing with specific forms of magnesium (300-400mg magnesium biglycinate or threonate), 50mg apigenin, and theanine 30-60 minutes before sleep. These compounds can synergistically enhance the transition to sleep by promoting GABA release and reducing forebrain activity.
29. Go to Bed Earlier if Waking Up Early
If you consistently wake up in the middle of the night (e.g., 2:30-3:00 AM) after pushing yourself to stay awake later than your natural sleepiness, try going to bed earlier. This aligns with your natural melatonin pulse and can prevent premature waking.
30. Keep Lights Dim if Waking Up at Night
If you wake up in the middle of the night (e.g., to use the restroom), keep the lights dim and turn them off as soon as possible. This minimizes disruption to your sleep-wake cycle.
31. Wake-up Time Logging
Write down the exact time you wake up each morning. This data helps you determine your temperature minimum, which is approximately two hours before your average wake-up time, and is crucial for timing your peak cognitive performance.
32. Utilize Non-Sleep Deep Rest (NSDR)
Listen to NSDR audio scripts, which guide deep body relaxation and simple breathing exercises. NSDR can restore mental and physical vigor, offset negative effects of slight sleep deprivation, and improve the ability to fall back asleep if you wake up at night.
