For quick relief on the spot, try the 5‑minute “cyclic sigh”: two inhalations followed by a prolonged exhalation
当场想缓过来，用 5 分钟「循环叹息」：吸气两段，呼气拉长
No cost at all. Just 5 minutes a day.
In a one‑month controlled trial where participants performed each of three breathing exercises for 5 minutes daily, all three proved more effective than an equal amount of mindfulness meditation at lifting mood and lowering respiratory rate. The “cyclic sigh” — which emphasizes lengthening the exhale — performed best. The method is simple: inhale once through the nose, then take a brief second inhale to fully fill the lungs, and finally exhale slowly through the mouth. This particular study relied on self‑reported data and involved a relatively small group of volunteers, yet it required zero expense.

8. For quick relief on the spot, try the 5‑minute “cyclic sigh”: two inhalations followed by a prolonged exhalation
Cost: No cost at all. Just 5 minutes a day.
In plain terms: In a one‑month controlled trial where participants performed each of three breathing exercises for 5 minutes daily, all three proved more effective than an equal amount of mindfulness meditation at lifting mood and lowering respiratory rate. The “cyclic sigh” — which emphasizes lengthening the exhale — performed best. The method is simple: inhale once through the nose, then take a brief second inhale to fully fill the lungs, and finally exhale slowly through the mouth. This particular study relied on self‑reported data and involved a relatively small group of volunteers, yet it required zero expense.
Benefit: This home‑based, randomized controlled trial compared three distinct 5‑minute daily breathing routines — cyclic sighing (focused on extended exhalation), box breathing (equal durations of inhale, hold, and exhale), and cyclic hyperventilation with pauses — against an equivalent mindfulness meditation regimen over a month. Using a mixed‑effects model on pooled data, each breathing technique outperformed meditation; cyclic sighing stood out for its superior impact on mood improvement (statistically significant at P<0.05) and on reducing breathing frequency (also P<0.05).
Evidence grade: B

Notes: Execute the exercise by inhaling once through the nose, briefly adding a second inhale to maximize lung expansion, then exhale gently and fully through the mouth for a full 5 minutes. Although this trial was conducted at home, relied on participant self‑assessment, and involved a modest sample size, its benefits are clear: it costs nothing, takes only five minutes, can be done anywhere, and offers modest but tangible advantages over standard mindfulness practice.

8. 当场想缓过来，用 5 分钟「循环叹息」：吸气两段，呼气拉长
成本: 不花钱。每天 5 分钟。
说人话: 每天做 5 分钟呼吸练习、坚持一个月，情绪改善和呼吸放慢都比同样时长的正念冥想好。几种呼吸法里，把呼气拉长的「循环叹息」最好。做法是用鼻子吸一口，再补吸一小口把肺撑满，然后用嘴慢慢吐尽。这只是一项试验，好坏靠本人自己报，但不花钱。
收益: 这是一项在家做、随机分组的对照试验，比较三种每天 5 分钟的呼吸练习和同样时长的正念冥想，持续 1 个月。三种呼吸法是：循环叹息（强调延长呼气）、箱式呼吸（吸气、屏息、呼气等长）、带屏息的循环过度换气（吸气长、呼气短）。把各人各次的数据放在一起算（混合效应模型），呼吸练习都好过正念冥想，尤其是以呼气为主的循环叹息。它在情绪改善（P<0.05，即这点差别不像是碰巧撞出来的）和呼吸频率下降（P<0.05）上都更好

备注: 做法是用鼻子吸一口，短暂再补吸一小口把肺撑满，然后用嘴把气缓慢长长地吐尽，重复 5 分钟。只有这一项试验，在家做，好不好由本人填问卷报，人数也不多。效果只是比冥想略好，解决不了问题。但它不花钱，只要 5 分钟，随时随地能做，性价比高
