# ENTRAINMENT GOVERNS YOUR ENERGY & FOCUS

## Summary

The transcript explores entrainment, a biological process where the nervous system anticipates future events based on regular patterns, leading to increased energy and focus. Using examples like exercising at the same time or viewing morning sunlight, the speaker explains how to leverage this mechanism for better performance in workouts, learning, and cognitive tasks.

### Key Points

- **Entrainment Defined as a Scientific Process** [00:01] — Entrainment is described as a scientific process that can be leveraged for better energy, focus, learning, and workouts, not just a word.
- **Regular Activity Leads to Anticipatory Energy** [00:15] — Becoming regular with activities (e.g., 2-3 days in a row) shifts neurochemistry and hormones, leading to an increase in energy before the activity.
- **Exercise Timing and Chemical Release** [00:44] — Exercising at roughly the same time (±15 min) for a few days releases adrenaline, norepinephrine, and cortisol, increasing alertness and energy.
- **Morning Light as an Entrainment Cue** [01:23] — Viewing morning sunlight (or 10,000 lux artificial light) within an hour of waking creates anticipatory alertness over a few days.
- **Entrainment is Not Placebo** [01:48] — Entrainment is not a placebo; the nervous system predicts recurring events, which explains the anticipatory responses.
- **Regularity Enables Easier Focus** [02:13] — The key is to be somewhat regular (not obsessive) with timing; even cognitive activities like reading become easier when done at the same time daily.

## Transcript

entrainment. Entrainment isn't just a word. It's not just a concept. It's a scientific process that you can leverage toward better energy, better focus, better learning, better workouts, and so on. If you do an activity regularly, say
for 2 or 3 days in a row, and that activity shifts your neurochemistry and your hormones in a particular direction, what will happen is then 10 or 15 that activity. You'll start to notice an increase in energy. And that increase in
energy is in part psychological, but it is in large part physiological. Let me give you an example of this. If you were to exercise at roughly the same time, it doesn't have to be the exact same time. Let's say the at a given time plus or
minus 15 minutes for two or three days in a row. And that exercise generates the release of adrenaline, epinephrine in your body, which most moderate to intense exercise does. It increases norepinephrine in the brain, which
increases alertness. Maybe there's an increase in cortisol, too. And by the the exercise induced increase in cortisol, provided those workouts aren't grueling and extends, you know, extend hours and hours and provided you can
recover, it's not a problem. It's a great thing. In fact, if you do that regularly for two a few days in a row, your body starts to anticipate the your body starts to anticipate the release of those molecules leading to an
increase in energy in the minutes preceding when you would normally start. I've said many times before on the Huberman Lab podcasts where other my book protocols, it includes a section on this as well that viewing morning
sunlight ideally in the first hour after you wake or even 30 minutes. That's rises, you'll have to use a 10,000 lux artificial light or wait till the sun comes out. But if you do that for a few days in a row, what you'll notice is
that you start to wake up and feel more alert in anticipation of that light exposure. Okay, this is not placebo effect. It's entrainment. It's the
ability for your nervous system to predict events that are soon to come because they've happened regularly. And you can leverage it so that you have more energy, more focus, better learning, better workouts. And the key
is to be somewhat, okay, here's the thing, somewhat regular about the timing of when you exercise. And this includes cognitive things. This includes somebody who has a hard time focusing as many people do these days, but you force
yourself to put your phone aside and, you know, read a book, if you do that at roughly the same time each day, and you don't even have to do it every day, what you'll soon notice is that getting into the work becomes easier. And yes, there
is a psychological component of it. But it's also the case that those molecules, neurotransmitters, and hormones that allow you to focus,
anticipation of the learning that you did roughly at the same time in the did roughly at the same time in the previous days.
