Improve Your Lymphatic System for Overall Health & Appearance

This episode I discuss the science and practice of learning physical skills: what it involves at a biological level, and what to focus on during skill learning at each stage to maximize learning speed and depth. I also describe what to do immediately after a training session (note: this is different than the optimal protocol for cognitive skill training) and as you progress to more advanced levels of performance. I also cover the science of skill-based visualization which does have benefits, but only if done correctly and at the correct times. I discuss auto-replay of skill learning in the brain during sleep and the value of adding in post-training ‘deliberately idle’ sessions. I cover how to immediately improve limb-range-of-motion by leveraging cerebellum function, error generation, optimal repetition numbers for learning and more. As always, scientific mechanism, peer-reviewed studies and science-based protocols are discussed.  Read the full show notes for this episode at hubermanlab.com.

This episode I explain the science of heating and cooling the body, a process called thermoregulation-- and how to apply that knowledge to significantly improve physical performance. I describe the three areas of our body that can remove heat (or bring heat into the body) faster than anywhere else, why that is so, and how proper cooling of these areas with specific protocols can allow people to perform 200-600% more volume and repetitions of resistance exercises at the same weight loads, or to run, cycle or swim significantly further. I also describe how to use directed cooling of so-called glabrous skin: the bottoms of feet, palms and face, to significantly enhance recovery times from exercise. Also, why the common practices of trying to heat up or cool the body via the torso or whole-body submersion in cold can be inefficient and/or dangerous-- and the better alternatives. Finally, I discuss the temperature-effects of caffeine, alcohol and anti-inflammatory compounds. The information in this episode is focused on mechanisms and tools for increasing athletic or exercise performance. For the full show notes, visit hubermanlab.com.

This episode I describe the biology of two essential hormones we all make: cortisol and adrenaline (also called epinephrine). Cortisol and adrenaline powerfully regulate our levels of energy, focus and immune system function. I describe various science-supported tools and practices to increase or decrease cortisol and/or adrenaline, depending on one's specific needs and goals. I also describe the biology of nootropics, and how cortisol and adrenaline can improve or degrade learning. Finally, I review the scientific data and tools for timing the release of these hormones to improve memory, energy and immune system function.

This episode discusses metabolism and how our thyroid hormone and growth hormone control our metabolism. I also clarify that metabolism isn't just about burning energy, it’s about converting energy from different sources into fuels for building and repairing our tissues such as muscle, brain, and tendons and mobilizing energy from body fat storage. I discuss the role of iodine, selenium, and salt for thyroid health, and how specific exercise protocols, amino acids and temperature can dramatically shift levels of growth hormone release in waking and in sleep. I also describe the current landscape of prescription compounds, peptides and other factors for changing levels of thyroid and growth hormone, and some of their risks. Throughout the episode, mechanisms and tools grounded in specific mechanisms are discussed.

This episode I discuss how hormones from our gut, liver, pancreas and brain control our appetite--and the specific tools we can use to adjust those hormones in order to achieve specific goals. I explain the brain areas that control our desire to eat, and our desire to stop eating. I discuss a hormone we all can make that is regulated by UV-rays from sunlight that reduces our appetite. I also explain that when we eat controls our appetite and not the other way around (and how to leverage that fact). I describe how we are basically always eating until we reach a threshold level of fatty acids and amino acids in our gut and the factors that can alter that signaling and make us eat far more than we need. I also explain how insulin, glucose and glucagon work, why cholesterol is so key for ovary, adrenal, liver and testes function and how the ketogenic diet impacts glucose and thyroid levels. As always, I describe many tools: specific supplements, prescription compounds, specific types (and timing) of exercise to regulate hormones, specific timing and types of eating, ways to reduce sugar cravings by triggering release of the hormone CCK, and more. Note: A future episode will cover Thyroid hormone. Also, I mis-spoke when explaining POMC neurons. I said “P-M-O-C” but should have said “POMC”. Apologies. The name I gave for what POMC is, however, was correct: "proopiomelanocortin".

In this episode, I discuss testosterone and estrogen hormones and how they impact the brain, body, and behavior after puberty. I also discuss how various behaviors such as exercise (resistance and endurance training) and sex or observing sex impact these hormones and their levels. I ask: "what specifically is it about such activities that impact testosterone and estrogen?"; the resounding theme is that when our nervous system is activated in particular ways, it drives our endocrine system and vascular system to activate or repress certain hormone networks in predictable ways. I also discuss peer-reviewed studies and protocols addressing (at a mechanistic level) how light, cold and heat, and respiration (breathing) can positively or negatively impact testosterone and estrogen. We discuss specific supplements and compounds that peer-reviewed studies illustrate can adjust testosterone and estrogen levels by changing their binding to other proteins, raising them directly, or changing other hormones released from the brain and pituitary. I discuss optimization in the normal reference ranges for these hormones, and I discuss pheromones, apnea, menstrual cycles, menopause and andropause.

In this episode, I discuss how hormones such as testosterone and estrogen and their derivatives impact the early development of the brain and body and their maturation. I review published data on environmental factors shown to powerfully alter hormone pathways in animals and humans and the effects of cannabis, alcohol and cell phones on testes, sperm, ovaries and hormones. I describe the predictable relationship between genes, beard growth and balding patterns, and the importance of estrogen for brain development in people of all chromosomal sexes. Finally, I discuss how the hormones we are exposed to in the womb shape the relative length of our finger digits, the sounds our ears make (yes you read that correctly), and how those correlate with people's self-reports of their sexual preferences. As always, basic information and tools are discussed. Read the full show notes for this episode at hubermanlab.com.

In this episode, I discuss the biology of emotions and moods in the context of relationships. I focus on the science of how early infant-caregiver attachment, combined with adolescence and puberty shape our adult patterns of attachment. I explain the three universal aspects of emotions, the reality of right-brain versus left-brain personalities, and how the roots of adult attachment are also grounded in specific aspects of puberty. I review what factors determine when puberty starts and ends, and the role of oxytocin and other chemicals in controlling how we perceive and remember others. As always, I refer to various practical tools including new tools for understanding and predicting our emotions before they occur, and neurochemicals that shape human connection.
