Huberman Tip of the Day!
They did a study on 47 healthy males. They assessed concentration performance using the d2 test of attention before and 30 min after the stress or control task. They measured salivary cortisol and alpha-amylase repeatedly before and up to 1 hr after stress. The stress group showed a significantly stronger improvement of concentration performance compared to the control group, p = .042. Any p-score less than 0.05 is considered significant and 0.042<0.05. So it's significant. But why? How did stress improve concentration? In simple terms, if a task is too easy, your brain doesn't release the neuromodulators it needs for focus (like adrenaline). Let's look at a video game for example. When you get stuck on a level. Why can you focus without light, caffeine, alpha gpc, etc.? Because the challenge, the stress... create your focus. If the game is too easy (or too hard), you don't have the urge to try harder. So let's make today's 90-minute bout like the game. What's a difficult task you need to get done soon? It could be a presentation, a new feature, an boring subject, or starting a business you've always wanted. All these bug you in some way. They activate your focus neurons. According to the study, this agitation, fear of failure, self-doubt, challenge, or deadlines trigger your focus and improve performance. Actually, I stress every time I write the email. I'm scared you don't like it. Or it's not good enough. And the stress pushes me to focus and try my best. Otherwise, I'd just watch sit and watch youtube. So thanks Reader. Thanks for stressing me out :) <3 You can have this focus too... as long as there's some challenge. So today, during your 90-minute bout, dive into the difficulty. The more difficult, the easier it is for you to focus. Choose and work on something challenging. Optionally, write down what you will do to remember it later. Dw, I don't get your data. Great job Reader.

How Much Water You Really Need An enormous number of studies have shown that even a slight state of dehydration, even 2% dehydration, can lead to a significant, negative, that is a negative impact on our endurance, strength, our cognitive performance, including memory, focus, and creative thinking... - AH Hydration is important. I don't understand organic chemistry enough to explain it. But the gist is, your cells need fluid. There are also chemical receptors that sense when you're...
Breathe With Your Nose This tool serves many purposes. Maybe you're a bit tense or down at the start of your day. Relax. When the weather is hot/humid. There's less air so it's hard to breathe well passively. And if you're sitting or standing with bad posture right now, then your nasal pathways are closed. So to fix all those, take a deep nasal breath. This works like a drug. Here's what Huberman said about nose breathing. It warms and moisturizes the air that you bring into your lungs, which...
Resist The Instant Gratification Huberman: For every bit of dopamine that's released, there's also a circuit that creates a downward deflection in pleasure. So, after feeling pleasure, you feel pain. Dopamine is a neuromodulator. It's a chemical in your body that controls motivation. When you have a lot of it, you start to pursue and create. When it's low, you feel lazy. All of us have 'baseline dopamine'. It's our constant level of dopamine. It's genetic. And we also have so-called 'dopamine...
