Optimal duration of cold and heat exposure for health benefits:" "when we calculated the numbers, we could see that it ended up being 11 minutes in total per week." "When we divide that out it corresponds to being in cold water 1 to 2 minutes at a time, but also in the sauna 10 to 15 minutes at a time." @SusannaSberg1 on @hubermanlab

How GLP-1 work for appetite suppression and weight loss. "What is glucagon-like peptide one? It is a peptide, which is a small little protein, that can dramatically suppress appetite." "Glucagon-like peptide one acts on receptors in the body in a portion of the nervous system called the enteric nervous system." "The peptide stimulates neurons that cause changes in the so-called mechanoreceptors of the gut, of the enteric nervous system, and make people feel full." @hubermanlab

How you can improve motivation and drive by carefully investing dopamine: "We can either spend our dopamine, or we can invest our dopamine." "Scrolling is spending, and it's the kind of spending we don't even notice that we're doing." "If you go do a workout, you're spending effort to do it, but you get something back on that investment." @Michael_Easter on @hubermanlab

Chess prodigy Josh Waitzkin developed a process to achieve peak performance in any craft or career. He’s applied it to the world of investing, professional sports, science and more. The MIQ Process. It is not a quick fix, but rather a rewiring of your default settings. @hubermanlab

Intermittent fasting protocol, benefits & myths: - Around 11-12 hours of fasting depletes liver glycogen, forcing the body to shift from burning carbohydrates to burning fat and producing ketone bodies. - Ketones are a cleaner fuel source. They generate less oxidative stress and require less energy to metabolize than glucose. - Ketones activate BDNF, supporting learning, memory, and neuroplasticity, while also increasing GABA to quiet mental noise and sharpen focus. - A 5:2 fasting protocol (500 calories on 2 days per week, normal eating the other 5) produced a 20% improvement in cognitive test scores compared to simple caloric restriction alone. - Early time-restricted eating (stopping food intake by 6-8 p.m.) produced a ~10 mmHg drop in blood pressure, comparable in magnitude to first-line hypertension medications. - Fasting doesn't cause muscle loss if paired with resistance training, prioritizing protein within the eating window is enough to preserve lean mass. @foundmyfitness on @hubermanlab

Breathing exercise to improve workouts and training: "The physiological sigh is as far as we know the fastest way to shift your nervous system from sympathetic drive to more parasympathetic drive, from a state of greater alertness to a state of greater calm." "The more that you can shift yourself from sympathetic drive to parasympathetic drive in between sets, the more energy and focus you can devote to exertion during your work sets." "If you do one, truly, just one physiological sigh at the beginning of the rest period, you are going to effectively shift your nervous system in the direction you want it to go during those rest periods." @hubermanlab

Foods that boost energy and increase metabolism: - Fermented foods (kefir, sauerkraut, kimchi, full-fat yogurt) - feed the gut microbiome and may improve glycemic control and reduce gut inflammation. - Coffee oligosaccharides - extracted from spent coffee grounds, shown to reduce adipose fat tissue in men in a placebo-controlled trial. - Ginger dissolved in warm water - a single serving significantly elevated the thermic effect of food over a six-hour measurement period, likely through the capsaicin receptor. @MPStOngePhD on @hubermanlab

Rick Rubin explains why the Grateful Dead were so good. "The Grateful Dead is a good example of a band where I feel like their albums are not their strong point." "But if you hear live recordings, they're really interesting and really different from each other." "Part of what makes the Grateful Dead interesting is their unpredictability." @RickRubin on @hubermanlab

The data on seed oils vs. saturated fats may be more nuanced than you think: In a 25-day controlled study, participants who snacked on corn chips (fried in seed oils) twice daily had better lipid profiles and lower lipoprotein(a) levels than those eating low-fat high-carbohydrate or high-saturated-fat snacks. Lipoprotein(a) is an independent cardiometabolic risk factor and the chips came out ahead. A reminder that the lipid story is more nuanced than the label on the package. @MPStOngePhD on @hubermanlab

Rick Rubin's daily routine: "I try to wake up slowly... going out into the sun as naked as possible to start the day." "I tend not to engage in any work until probably 11:00 a.m. would be the soonest, and some days not until 1:00. And then I do focused work until maybe 6." "From the time the sun sets, I'm wearing red glasses. I'm in a space with only red light." @RickRubin on @hubermanlab

Cell phone usage and EMFs can have a negative impact on sperm health and testosterone levels: "The electromagnetic fields and the heat-related effects of smartphones can indeed have a detrimental effect on sperm quality and, yes, indeed, on testosterone levels as well." "Phones emit radio frequency electromagnetic waves and have potential adverse effects on brain, heart, endocrine system, and reproductive function." "Probably not a problem for most males to carry their phone. But probably best to not carry it in the front pocket. Maybe even avoid carrying it in the back pocket as well." @hubermanlab

Do you have to be dissatisfied to be driven? James Clear: I look at my current state and I realize there's a gap between where I am and where I want to be. And that dissatisfaction with that gap is what drives you forward. It's the drive to close the gap that gets you to show up and work hard or take the test or do the thing. And I think certainly there are many times in my life when that has been the driving force. But the healthiest response I think that I've come up with, or the counterpoint, is imagine that like an acorn falls from a tree and it manages to take root and starts to grow. And at first it's just this little acorn and then it's a sapling and then it grows into this eventually this large mature oak. And at no point in that process was it like berating itself for only being an acorn or for only being a sapling, right? For not being enough yet, for not being big enough, for not having achieved that outcome. Nobody looks at it and thinks, "Oh, what a failure. You aren't a full oak tree yet." And yet, despite that, there isn't this dissatisfaction going on. It continues to grow. And I think the answer there is it grows simply because that is what an oak tree does. It grows because that is what it is encoded to do. And so I feel like the healthiest version of me, like just flowing with it, you know, or just stepping into it is: What do I feel like I'm encoded to do? This is my strength. This is what I like. It lights me up. It makes me feel alive. And then I can be quite driven and not feel dissatisfied in the moment. @JamesClear on @hubermanlab

Diet quality is one of the more underappreciated levers for sleep. Closer alignment with the Mediterranean or DASH diet is associated with better sleep duration, fewer insomnia symptoms, and lower likelihood of developing insomnia over time. Insomnia isn't static. It can resolve. Diet appears to be one reason why. @MPStOngePhD on @hubermanlab

Tinnitus is very common, also the No. 1 military disability & costs $1B per year to taxpayers. In most cases it’s preventable. It happens because of neuroplasticity gone awry. Neuroplasticity is also how you fix it. Dr. Michael Kilgard on @hubermanlab

Why deep focus is difficult to drop into and how to improve your ability to do it: - The first 10-15 minutes of distraction-free work feel excruciating... If you push through, sustained focus becomes available for hours. - Phones literally drain acetylcholine, the brain chemical that creates attentional focus. - Changing your environment resets your focus, moving to a new cafe or seat can break a mental rut the same way interval training resets the body. - Effortful cognition works on its own timeline: scheduling thinking-intensive work before downtime (a flight, a walk) lets ideas marinate without forcing them. @JMGrohNeuro on @hubermanlab

Simple test for gauging recovery and workout readiness: "How do you know when a muscle is ready to be challenged again?" "If you're training when you're really sore, it's probably not a great idea and it's a good indication that that muscle's not recovered." "When you start to see a drop-off of 10% or so, or even greater, of your grip output, you really should skip the gym that day." @trainer2thepros on @hubermanlab

Supplements that can help improve sleep: - Myoinositol - Theanine - Magnesium threonate - Magnesium bisglycinate - Apigenin @hubermanlab

How dopamine controls your motivation: "Dopamine is released in anticipation of what we want." "Desire for things increases dopamine, but then our level of dopamine drops below baseline." "That drop below baseline triggers the motivation to bring that dopamine level back up by going and pursuing the thing that you wanted in the first place." @hubermanlab

3 steps for curing a hangover based on science: 1. Restore the gut microbiome: "Ingesting low sugar fermented foods or maybe a prebiotic or probiotic to support the gut microbiome might assist in some of the gut-related malaise associated with hangover." 2. Deliberate cold exposure: "One could imagine using deliberate cold exposure as a way to accelerate the recovery from hangover, provided that's done safely... There's some evidence pointing to the fact that when levels of epinephrine, adrenaline are raised in the brain and bloodstream, that some of the components of alcohol metabolism can be accelerated." 3. Consume electrolytes: "Making sure that you have enough sodium, potassium, and magnesium, so-called electrolytes is going to be important for proper brain function, bodily organ function." @hubermanlab

Peptide that might improve sleep & cognitive function: - Pinealon is a tripeptide (EDR) originally developed from Soviet-era research to reverse accelerated aging in soldiers, submariners, and astronauts with disrupted circadian rhythms. - Taking it at the start of the night can reduce deep slow-wave sleep and spike REM. Taking it mid-sleep, after waking, shifts the ratio toward more REM in the final hours. - Anecdotally, users describe less morning brain fog, sharper daytime alertness, and better performance during high-intensity training. @AbudBakri on @hubermanlab
