Brian Johnson explains how meditation cools your amygdala, the brain's alarm system that triggers fight-or-flight responses. Regular practice, like 20 minutes morning and night, quiets an overreactive alarm that fires at things that aren't actually threats.
You're listening to Optimize with Bryan Johnson. More wisdom in less time. Hi, this is Brian. Welcome back to another micro class. This one's on meditation Mind alarm. It's inspired by success through stillness. Russell Simmons is a super funny, casual guy. Reading this book feels like you're kind of just hanging out and talking to him. Super intense, funny, wise guy. Anyway, he uses a lot of great metaphors. One of the most helpful, I think is this idea of there's your brain. In your brain, somewhere in this region, you have a limbic system. Your limbic system is one of the older parts of your brain that is responsible for your basic emotions and stuff like fight or flight. This is a highly abridged description of it, right? And he says that your amygdala, almond shaped, sits right about there, give or take. Might be over here, but what's to say it's here for now, right? And then amygdala kind of acts as like a guard to your limbic system. It is sitting there interpreting your world to see what requires a response from your limbic system should you get into fight or flight. Right? So if you have a super hot amygdala, he says it's kind of like having a car alarm that, that goes nuts at the simplest thing. So a car alarm is useful. You wanna have a car alarm if you're concerned about having someone steal your car, but you don't wanna have a car alarm go off on things that aren't really a threat, right? So if a car drives by with loud music, your car alarm shouldn't go off. If the wind is kinda blowing, your car alarm should not go off. It's the exact same thing with our lives, right? If we have an oversensitive amygdala, it's, it's kind of like having this oversensitive car alarm and every little thing that goes on in our lives, that person said this and boom, your amygdala says, hey, let's blow up our fight or flight. Release all kinds of stress toxins because our life is blowing up. No, it was actually just a car driving by. No one was trying to steal your car. You can settle down. You don't need to trigger this intense response. Now the whole point of this is that one of the ways to calibrate your amygdalamind alarm system is via meditation. It's proven to cool this hot amygdala. So you view proper things as threats. We want to keep this fight or flight there. Certain things require a deep response, right? But not every single little petty thing that ever goes on. So know that meditation provides that benefit. And if you have a mind alarm that goes nuts at the smallest things and you're not meditating, you may want to invest 20 minutes in the morning, he would say, and 20 minutes at night. But invest some time in cooling your mind off and training your amygdala to respond properly, rather than like this crazy alarm, which of course annoys not only the car owner but everyone around them. If you're the type of person that blows up at every little thing that goes on, you're blaring his alarm, which is annoying for you and everyone else. So let's cool it down.
