Quick improvements in focus and stress, but the effects are fragile and disappear without consistent practice.
Yogis with 27,000+ hours show "extraordinary" qualities, such as constant high-amplitude gamma waves—a state associated with peak performance and "effortless" awareness. Why It Matters Altered Traits: Science Reveals How Meditation ...
In Altered Traits , science writer Daniel Goleman and neuroscientist Richard Davidson strip away the "McMindfulness" hype to reveal what meditation actually does to the human brain. Moving beyond the temporary "state" of relaxation, the authors focus on "traits"—enduring physical and psychological changes that persist long after you leave the cushion.

Expert meditators (those with over 10,000 hours of practice) show brain patterns that are fundamentally different from the average person, even while asleep. Key Scientific Takeaways
