Thank you for joining the Huberman Lab Neural Network — a once-a-month newsletter with science and science-related tools for everyday life. This newsletter aims to provide you with actionable information in a condensed form.In the episode “Using Caffeine to Optimize Mental & Physical Performance,” I discuss one of the most widely used substances in the world: caffeine.Most people are drawn to caffeine's ability to increase alertness and reduce feelings of sleepiness and fatigue. This newsletter explains how caffeine affects the brain and body to produce these effects and describes science-supported tools, caffeine schedules and dosages to best leverage caffeine for physical and mental performance.Caffeine Dosage & ScheduleIt’s important to determine an optimal caffeine dose and schedule. Follow these tips to discover your personalized caffeine dose:Dose: Start with 1 to 3 mg of caffeine per kilogram body weight. If sensitive, start lower.For example, I weigh ~100 kilograms (220 pounds) so a tolerable dose of caffeine is 100 to 300 milligrams. However, I often consume more than that since I'm quite caffeine-adapted.Research the caffeine-containing beverages (soda, tea, coffee, energy drinks) that you consume.Popular coffee and energy drinks can contain anywhere from 50 to 500 and as much as 800 milligrams of caffeine (!), depending on the size and source.Avoid extended consumption of high levels of caffeine — there is an increased risk of headaches, anxiety, irritability and blood vessel damage.Caffeine is a diuretic, causing the loss of fluid, sodium and other electrolytes.Consume equal volumes of water with your caffeine to avoid jitteriness, blurry vision or a low blood sugar feeling.Ideally, add a small pinch of sea salt, table salt or electrolyte-replacement powder like LMNT to the water (Note: LMNT is a Huberman Lab sponsor).Supplement: If you experience any anxiety or jitteriness when consuming even smaller doses of caffeine, consider supplementing with theanine to reduce those negative effects. Many energy drinks include 100-200 mg theanine for this reason.Timing TipsTo time caffeine consumption appropriately throughout your day, follow the tips below:If you tend to experience an afternoon crash, consider delaying your caffeine intake for 90 to 120 minutes, but otherwise, caffeine first thing is

Evidence behind waiting 90 minutes after waking before caffeine?

The stimulating effect of caffeine is one of the main reasons so many people enjoy a daily cup of coffee. You can expect an 8-ounce cup of coffee to provide just under 100 milligrams (mg) of caffeine and a 12-ounce cup with approximately 140 mg. But where does that fall in terms of recommended daily allowances of caffeine? Can you expect similar caffeine amounts from home-brewed coffee vs. a cup you pick up from a coffee shop? This article examines how much caffeine you can expect from your coffee, including factors influencing caffeine content, and gives a general guideline on daily caffeine limits. Stefania Pelfini, La Waziya Photography / Getty Images Milligrams of Caffeine in One Cup of Coffee The amount of caffeine in a standard cup of coffee can vary depending on factors such as the type of coffee beans, the brewing method, and the serving size. On average, an 8-ounce cup of brewed coffee contains approximately 90–95 milligrams (mg) of caffeine. However, this amount can fluctuate, with some cups containing as little as 70 mg and others having as much as 140 mg or more. In addition, if you drink decaffeinated coffee, you are still getting some caffeine. On average, an 8-ounce cup of decaf coffee contains around 2–5 mg of caffeine. It's important to be mindful of caffeine intake, especially if you're sensitive to caffeine's effects. Following is a closer look at some of the main factors involved in determining caffeine amounts. Coffee Size Not all cups and mugs of coffee of the same portion size. Logically, there's 3 times as much caffeine in a 24-ounce mug vs. an 8-ounce cup of the same brew. If your goal is to keep your daily caffeine intake to an allotted amount, it may be best to opt for a smaller portion, especially if you drink more than one coffee daily. Coffee Type Certain types of coffee and brewing techniques result in slightly higher caffeine levels. However, some studies have found no significant differences in caffeine content when comparing specialty-grade brews to other popular brands. Some of the types of coffee that may have the most caffeine per serving are: Robusta coffee beans: Robusta beans typically contain more caffeine than Arabica beans. Robusta beans are often used in espresso blends and instant coffee, contributing to higher caffeine levels in these types of coffee.Dark roast coffee: Contrary to popular belief, dark roast coffee beans usually contain slightly less caffeine than lighter roasts. However, dark roast coffee often has a bolder flavor, which may give the perception of a higher caffeine content.Espresso: While espresso shots are smaller in volume than a standard cup of coffee, they tend to have a higher concentration of caffeine due to the brewing method: the pressure and short extraction time used in making espresso extract more caffeine from the coffee grounds.Cold brew coffee: Cold brew coffee is made by steeping coffee grounds in cold water for an extended period, typically 12 to 24 hours. This method extracts

Be better at, well, life. His approach—holistic and data-driven— focuses on improving everything from nutrition to exercise to mindfulness to sleep. If your mind and body are balanced, espouses Roethlingshoefer, you can excel at anything. I’m no CEO, but Roethlingshoefer agreed to take my case, crunch my data, and see where I could make improvements. During our first Zoom meeting, Roethlingshoefer asked about my lifestyle. He has the intensity and focus of a pro athlete tempered by the patience and understanding of a good doctor. (Makes sense; he holds a masters in sport performance and human biology, and he's worked as a performance director for the NHL and the NCAA.) I went through my fitness routine—HIIT training once a week; cardio, weights, and yoga the rest of the time—and he nodded approvingly. We talked through my bedroom setup (cool, quiet, comfortable) and lighting (low, dimmable) which he said are also good. Then he asked about my food and alcohol intake. Bad news! I usually eat dinner too late and drink too much booze. (I’m an Esquire editor, it’s part of the job.) Such consumption so close to bedtime, he explained, loads my body with a lot more digestive work. This disrupts sleep. “When’s the latest you have caffeine during a typical day?” he asked. I told him about my daily four o'clock espresso—one of my favorite routines. He shook his head verydisapprovingly. “Caffeine has a half-life of five to seven hours," he said. "If you drink a cappuccino with 180 milligrams of caffeine at 4:00, there'd still be 90 milligrams in your system at 11pm.” We formulated a plan. I'd replace my beloved espresso with an afternoon decaf. He also suggested a small tweak to my fitness routine: adding a set of sprints to my jogging. He told me to pick a bedtime and a wake-up time, and to stick to them. (I settled on, respectively, 11pm and 7am.) And, like practically everyone else on the planet, I’m on my smartphone way too much. Turns out the light from the screen tricks my brain into thinking it’s still daylight, which prevents my body from releasing the hormones that help me sleep. I told Roethlingshoefer this was a lot to combat. Unfazed, he suggested I start by adhering to what he called the 3-2-1 rule. Yiu Yu HoiFollow the 3-2-1 RuleRoethlingshoefer explained that optimal sleep is only achieved under optimal conditions..
