📝 Podcast Summary
The four pillars of neurochemistry for optimizing mental and physical health
Understanding the mechanisms and chemicals in the brain help in optimizing mental health, physical health and performance. There are four major pillars of neurochemistry that allow us to focus, relax, optimize sleep, and work through pain. These pillars comprise a small subset of chemicals that we leverage to effect positive change in our lives. Understanding these pillars will help us navigate the vast landscape of mental health, physical health, and performance tools that are available for us to use. Two recent studies related to sleep in humans show that understanding different forms of metabolism during sleep can help us access better sleep. These studies can provide exciting and actionable information on optimizing sleep.
Sleep States and Their Effects on Metabolism
Sleep states regulate more than 50% of all the metabolite features detected in human breath, which can reveal what humans are metabolizing, such as more lipids or more carbohydrate. Transitioning between slow wave sleep, rapid eye movement sleep, and waking affects specific metabolic pathways related to lipid metabolism, fat metabolism, or carbohydrate metabolism. The range of different types of metabolism during sleep may serve to ensure that the specific aspects of metabolism required during wakefulness are working properly. Getting enough sleep, including slow wave sleep and rapid eye movement sleep, is extremely important for optimizing metabolic circuits for human performance and health. Lack of sleep can disrupt glucose metabolism and alter certain forms of fuel utilization during the night and wakefulness. It is important to get sufficient quality and duration of sleep and transition through all the different aspects of fuel utilization.
Shifting Your Sleep Schedule for Improved Mood and Cognitive Function
A study published in the Sleep Medicine journal shows that people can shift their sleep schedule by a few hours, and it's not even that challenging to do provided you do the right things. The study found significant improvements in mood and cognitive performance, including reaction times and physical grip strength, among those who regularly slept late and woke up late but shifted to waking up earlier and going to sleep earlier. The interventions used in the study included maximizing outdoor light exposure during morning hours, consistent sleep-wake times, fixed meal times, limiting caffeine intake and exercise. These interventions can help in resetting the late timing of night hours, positively impacting mental and physical health.
Optimizing Sleep-Wake Schedule through Daily Habits and Neurobiology
Consistently keeping meal times, avoiding caffeine and napping after 4 PM, exercising in the morning and getting maximal sunlight exposure earlier in the day are some effective ways to shift sleep-wake schedules earlier. This study incorporates many different features, including previous animal studies and human studies, to tackle multiple variables simultaneously. Your nervous system plays an important role in generating everything from sleep to wakefulness and interacts with organs via synaptic communication. Neurons communicate with each other through chemicals, and the chemicals released can make other neurons more or less electrically active. Understanding basic biology can help optimize brain chemistry for better health and performance.
Understanding Neural Circuits and Neuromodulators for Emotional Control
Neurons communicate with each other through electricity and chemicals in synapses, which can either excite or inhibit the next neuron, leading to specific behaviors and emotional states. These neural circuits are made up of multiple brain areas that light up in particular sequences, and the chemicals that control which neural circuits are active are called neuromodulators, such as dopamine, epinephrine, serotonin, and acetylcholine. By learning to control these neuromodulators, through behavioral tools and supplementation, one can access desired brain and body states. Understanding the complexity of how the brain works is vital in controlling one's emotions and behaviors, allowing for a more fulfilling life.
Role of Neuromodulators in Brain Functions and Their Time-Dependent Actions
Neuromodulators like dopamine, serotonin, epinephrine, and acetylcholine are always present in different levels. They work together to impact certain circuits in the brain and create states of focus, motivation, energy, and learning. The fast actions of these neuromodulators occur on the order of seconds, minutes, or up to an hour, whereas the slower actions occur on the order of hours, days, or even weeks. The levels of neuromodulators vary depending on the time of day or night. From zero to nine hours after waking, dopamine and epinephrin tend to be at their highest levels, called phase one. Then from nine to 16 hours is phase two where dopamine and epinephrin levels subside a bit while serotonin levels start to increase. Phase three is the 17 to 24 hour period where neuromodulator levels are all over the place during sleep.
Understanding the Basics of Brain Chemistry for Effective Optimization
To optimize brain chemistry, it is important to understand the backdrop baseline elements of neuromodulators and hormones that vary throughout the day. Dopamine and epinephrine tend to dominate in the early phase one of the day, while serotonin dominates in phase two. Leverage tools that can affect neuromodulators based on the backdrop level of the specific neuromodulator, such as using potent tools for adjusting dopamine and epinephrine levels during the late part of the day. Hormones, like steroid hormones, can also affect brain chemistry by controlling gene expression and altering cell identity. Understanding these elements can help leverage the best tools for optimizing brain chemistry in short durations.
The Link between Hormones and Neuromodulators for Mental and Physical Health
Hormones and neuromodulators in the body are closely linked and have both slow and fast actions on cell identity and brain function. Hormones like testosterone tend to collaborate with dopamine and cortisol with epinephrine, while oxytocin and prolactin tend to collaborate with serotonin. Acetylcholine works on its own, but its effects can also be impacted by hormones. Increasing testosterone and estrogen levels can have positive effects on feelings of wellbeing and libido by modulating dopamine and serotonin levels. Understanding the relationship between hormones and neuromodulators is important for improving mental and physical health. Prolactin tends to reduce dopamine levels, while elevating serotonin.
Understanding the Role of Neuromodulators for Achieving Desired States of Body and Mind
Understanding the role of different neuromodulators such as dopamine and epinephrine can help in creating a kit of tools that can be used to achieve desired states of body and mind. Dopamine is responsible for motivation, craving, and pursuit of goals whereas epinephrine is responsible for increasing energy and state of readiness. Both these molecules are closely related and can collaborate with each other. Prolactin tends to decrease the effects of dopamine. Knowing about these neuromodulators and their interactions can help in selecting the right tools, be it pharmacologic, behavioral or supplementation based, to achieve focus, less stress, higher motivation, and better learning. It is important to understand that none of us have designed these circuits and they work in a seesaw fashion.
The Role of Serotonin and Acetylcholine in Brain and Body.
Neuromodulators, such as serotonin and acetylcholine, have significant impact on our brain and body states. Serotonin promotes contentment and relaxation, while acetylcholine is associated with focus and learning. Levels of these neuromodulators matter, as high levels of serotonin can lead to sedation and low levels can cause agitation and stress. Acetylcholine can be released during calm states, such as in the case of a person's hyper-focus on a newborn baby. Understanding the impact of neuromodulators and how to increase dopamine levels above baseline can help individuals be more motivated, pursue goals, have more energy, and focus better.
How Sunlight and Caffeine Increase Dopamine Production and Motivation
Sunlight exposure early in the day and regular ingestion of caffeine at appropriate levels can increase the potency of dopamine production. Increasing the number of dopamine receptors in the brain can lead to increased motivation, mood, and pursuit of life goals. However, it is important to note that both tools must be used safely and in moderation to avoid harmful effects like skin burn, blindness, or adverse caffeine side effects. It is crucial to understand the natural behavioral tools for increasing dopamine and to incorporate them into your daily routine consistently. These tools are science-backed and versatile but must be applied mindfully following guidelines to ensure benefits.
Managing Caffeine and Dopamine Levels for Better Sleep and Focus.
Limit caffeine intake early in the day and avoid drinking it past 2 PM or 4 PM. Too much caffeine disrupts the architecture of sleep and can be harmful. For most people, anywhere from 100 to 400 milligrams of caffeine is going to have this effect. Tyrosine-rich foods increase dopamine levels and improve mood, motivation and focus. Avoid the cheese effect caused by excess tyrasine if taking drugs that manipulate dopamine pathway. Bad drugs like cocaine and methamphetamine that increase dopamine levels are destructive and should be avoided. Prescription drugs like Ritalin, Adderall, Vyvanse, Modafinil, and armodafinil require a prescription and should be taken in consultation with a physician. There are supplements that can very potently increase dopamine levels, but talk to a knowledgeable physician before adding or removing anything from your supplementation protocols.
Different ways to increase dopamine levels in the brain
Supplements like Macuna purines can increase dopamine, but may lead to a substantial crash afterwards. L-tyrosine and phenylethylamine can also increase dopamine, but their effectiveness varies depending on the individual's sensitivity and natural baseline levels of dopamine. Deliberate cold exposure is the most potent behavioral tool for increasing dopamine in a sustained way. It has been shown to cause long sustained increases in dopamine and epinephrin in the brain and body. Although colder water temperatures are more effective at increasing dopamine, one does not need to endure two hours in 60°F water to achieve this benefit.
Harnessing Dopamine Boosts with Simple Practices
Exposure to cold water for as short as 30 seconds can lead to long-lasting increases in dopamine and epinephrine. One can use a cold shower instead of ice floating in the bath, but the temperature should be safe yet uncomfortable. The ideal way to evoke dopamine and epinephrine release is through cold water immersion. Sufficient amounts of B vitamins are necessary to keep prolactin levels in check and not quash dopamine in the system. Excessive bright light exposure to the eyes between 10 PM to 4 AM or phase three of the circadian cycle can reduce dopamine levels and activate a neural circuit. Therefore, it is essential to maintain dopamine baseline through certain strategies like sunlight exposure and proper dietary intake.
Boosting Dopamine Levels and Epinephrine for Increased Energy and Focus
To increase dopamine levels and receptor efficacy, use a combination of behavior, nutrition, and supplementation. Avoid things that suppress dopamine, such as bright light exposure and elevated prolactin. Dopamine levels are lower later in the day, so adjust your use of tools accordingly. Epinephrin increases energy and the desire to move, but many people associate it with stress. However, increasing epinephrin early in the day can help with alertness and focus. Physical activity, even talking, increases epinephrin levels. Your kit of tools is highly individual and can be adjusted depending on your circumstances.
Tools for Increasing Energy Levels
Exercise, caffeine, cyclic hyperventilation, and deliberate cold exposure are potent tools for increasing epinephrin and thereby energy levels. Exercise increases epinephrin transmission from locus coeruleus and adrenaline from the adrenals. Caffeine increases epinephrin and limit sleepiness if taken 90-120 minutes after waking. Cyclic hyperventilation and deliberate cold exposure increase adrenaline and make one more alert, energized, and wide-eyed. However, cyclic hyperventilation may cause agitation to people with anxiety or prone to panic attacks. While there are no foods to increase epinephrin, foods that contain tyrasine increase dopamine; dopamine is the molecule that is synthesized into epinephrin. Thus, combining these tools provides a versatile kit for increasing physical and mental energy.
How Acetylcholine Affects Attention and Learning in the Brain
Acetylcholine is a neuromodulator associated with states of focus, attention, and learning. It is released from two major brain sites, nucleus basalis and the back of the brain, which promote the synthesis of more precise neural circuits. The brain filters sensory information and acetylcholine increases the extent to which visual and auditory information reach consciousness. To increase acetylcholine levels, one can eat foods that contain precursors like beef liver, eggs, chicken, mushrooms, and kidney beans. Supplementation with molecules like nicotine can also increase acetylcholine, but it is not recommended due to addiction and other negative health impacts. Increasing acetylcholine levels before and during learning can help retain information and trigger neuroplasticity.
Boosting focus with supplements and tools
Nicotine can enhance focus and cognitive performance, but it affects people differently. Some individuals are sensitive to ingested nicotine and may feel terrible after taking it, while others feel fine. Alpha GPC and Huperzine supplements increase acetylcholine levels, which can enhance focus. However, taking high doses of alpha GPC chronically over time may increase the risk of stroke. Taking 600 milligrams of garlic alongside alpha GPC can prevent an increase in TMAO levels that are sometimes associated with increased cardiovascular risk. Behavioral tools like deliberate visual focus exercises can also enhance focus by increasing the amount of acetylcholine transmission in particular neural circuits. The cognitive and performance effects of acetylcholine are impressive in children, and protocols are being actively deployed in schools in China and elsewhere.
Behavioral, Nutritional, and Supplementation Tools to Increase Serotonin
Behavioral tools, nutritional tools and supplementation tools can modulate serotonin system, leading to increases in feelings of wellbeing in positive ways. Observing others giving and receiving gratitude is the most potent way to increase serotonin in the brain and body while receiving not giving gratitude has the most potent effects on increasing serotonin and activity of the brain circuits involving serotonin. Amino acid tryptophan is upstream of serotonin synthesis and enriched in tryptophan containing foods like white meat turkey, that can lead to net increases in the amount of serotonin available in the brain and body. However, overeating can also cause sleepiness as there is a diversion of blood away from other tissues, making you feel sleepy.
Foods and supplements that can increase serotonin levels
Eating foods rich in tryptophan can increase serotonin levels in the body, which may improve overall mood and wellbeing. Some of these foods include milk, oats, cheese, nuts and seeds, chocolate, and certain fruits. While supplements like Cicis quadrangle Doris and 5 HTP can also increase serotonin levels, individuals need to be cautious and cycle their use as the data on their effectiveness and safety is limited. Another molecule that can increase serotonin levels is myo-inositol, which has been explored for its potential in treating anxiety and improving sleep. However, individuals should note that sensitivity to these supplements varies and they should consult with a healthcare provider before trying them out.
Myo-inositol, Serotonin, and Behavioral Protocols for Mental Health.
Myo-inositol is a supplement that has been explored for the treatment of bipolar disorder, migraine, ADHD, and for increasing serotonin. However, high doses of myo-inositol can cause gastric discomfort and sedative effects. It is important to consult with a physician before adding or removing anything from your drug protocol or prescription protocol. Apart from supplements, behavioral protocols such as physical contact, cuddling, holding hands, receiving and observing gratitude can increase serotonin levels. It is also important to have sufficient baseline levels through a balanced diet and regular behaviors, and only use supplementation or prescription drugs when appropriate. Understanding these neuromodulators - dopamine, epinephrine, acetylcholine, and serotonin - can provide a framework to address various health concerns.
Understanding Neuromodulators and Their Impact on Mental and Physical Performance
When it comes to mental and physical performance and overall wellbeing, we are dealing with potent neuromodulators in our brain and body. There are no simple tests to know our dopamine or serotonin levels, but we can use versatile tools from nutrition, supplementation, or prescription drugs to manipulate our neurochemical ingredients to achieve desired states. Different neuromodulators like dopamine, acetylcholine, or serotonin put us into different mental and physical states. Understanding how protocols work and how they tap into these major neuromodulator systems can help us gain intuition and customize these protocols for our own wellbeing. Experimenting with these tools in a safe way can help us figure out what levels of these neuromodulators are appropriate and necessary for us.
