※腹式呼吸など意識せず、いつもどおりの呼吸で行う
2. 鼻から入る空気・口から出る自分の息を「待つ」感覚で呼吸を繰り返す
3. 雑念が浮かんだらそれを受け流し、再び自分の呼吸に意識を戻す
4. どうしても雑念が浮かぶ場合は呼吸にラべリングする
1…2…3…と数字を心の中で唱えて、合わせて呼吸をしてみる
Masahiro Yanase
実践方法 – STEP3. 心の持ち方
16

ダンベルの重さに抵抗して筋肉を収縮させる度に、筋肉が少し強くなる。
 マインドフルネス・メディテーションは…
呼吸から注意がそれ、元に戻す度に注意の筋肉が強くなる。
悪い瞑想はない

マインドフルネス 〜データサイエンスに基づいた現代人の脳のアップデート〜

Notes de l'éditeur

  1. 一言で伝えたい事が分かるタイトル
  2. DMNは大食漢!! 物事を考えるために追加で必要なエネルギーは+5%程度
  3. うつ病の方にはネガティブ思考の反復(反芻思考[rumination])が見られる
  4. 海馬 記憶や空間学習能力に関わる器官。 情報を最初に受け取り、過去の記憶からカテゴライズする。 扁桃体 脳の警報装置。 快・不快を判断し、原始的な情動反応を起こす。 前頭前野 脳の司令塔。理性を司り、冷静な判断を下す。 恐怖も怒りも医学的には同じ反応が起きており、「恐怖で血の気が引く」「怒りでアタマに血が上る」という表現があるが、実際はともに血液は身体にいく。
  5. うつ病の方にはネガティブ思考の反復(反芻思考[rumination])が見られる
  6. DMNが司るのは、内側前頭前野・後帯状皮質・楔前部・下頭頂小葉からなる脳回路
  7. 脳は変わる!-脳の可塑性
