Breathing Exercises for Breath-Hold and CO2 Tolerance Training 屏息与二氧化碳耐受力训练的呼吸练习
Progressive breath-hold training with 5-5-5 cycling builds CO2 tolerance, delays the urge to breathe, and improves performance in swimming, freediving, and high-intensity sport.

- Always practice breath-hold training sitting or lying down — never in or near water without a trained safety buddy.
- Begin with a 2-minute relaxation using slow breathing to lower your baseline CO2.
- Inhale fully through your nose for 5 counts, hold for 5 counts at comfortable capacity, exhale slowly for 5 counts.
- After 5 breath cycles, extend the hold to 10 counts — note the sensation of CO2 buildup without resisting it.
- Build progressively over weeks: aim to increase hold duration by 5 seconds per week while maintaining calm.
如何练习
- 屏息训练始终坐着或躺着进行——在没有训练有素的安全伙伴的情况下，切勿在水中或水边进行。
- 从2分钟缓慢呼吸放松开始，降低基础二氧化碳水平。
- 用鼻子充分吸气5拍，在舒适容量下屏息5拍，缓慢呼气5拍。
- 5个呼吸循环后，将屏息延长至10拍——感受二氧化碳积聚的感觉而不要抗拒它。
- 在数周内逐步进展：目标是每周将屏息时间增加5秒，同时保持冷静。

Frequently Asked Questions
常见问题
What is CO2 tolerance and why does it matter for breathing? 什么是二氧化碳耐受力，它对呼吸为什么重要？
CO2 tolerance is the ability to remain calm and functional as blood CO2 levels rise — which happens whenever you exercise hard, hold your breath, or breathe slowly. The urge to breathe is primarily triggered by rising CO2, not falling oxygen. People with low CO2 tolerance feel a strong urge to breathe at lower CO2 thresholds, leading to over-breathing (breathing more than metabolic demand requires), which can worsen anxiety and reduce athletic performance. Lindholm and Lundgren (Journal of Applied Physiology, 2009) documented the physiological adaptations in breath-hold divers, demonstrating that systematic training raises the CO2 threshold at which the breathing reflex fires.
二氧化碳耐受力是在血液二氧化碳水平上升时保持冷静和正常功能的能力——这在剧烈运动、屏息或缓慢呼吸时都会发生。呼吸冲动主要由二氧化碳升高触发，而非氧气下降。二氧化碳耐受力低的人在较低的二氧化碳阈值时就会感到强烈的呼吸冲动，导致过度呼吸（呼吸量超过代谢需求），这可能加剧焦虑并降低运动表现。Lindholm和Lundgren（《应用生理学杂志》，2009年）记录了自由潜水员的生理适应，证明系统训练能提高呼吸反射触发的二氧化碳阈值。
How can I improve my breath-hold time? 如何提升我的屏息时间？
The most effective approach is progressive CO2 tolerance training: systematic breath holds that progressively expose the body to higher CO2 levels. Practicing at a comfortable breath-hold capacity (not maximum) and extending duration by small increments over weeks is safer and more effective than trying to hold breath to the limit. Woorons et al. (International Journal of Sports Physiology and Performance, 2017) demonstrated that repeated sprint training with voluntary hypoventilation significantly improved CO2 tolerance and exercise performance. Key supporting habits include nasal breathing during daily life, slow breathing practice, and reducing mouth breathing — all of which gradually recalibrate the CO2 response threshold.
最有效的方法是渐进式二氧化碳耐受力训练：系统性屏息练习，逐渐使身体暴露在更高的二氧化碳水平下。在舒适的屏息容量（非最大值）下练习，并在数周内小幅度延长时间，比尝试屏息至极限更安全、更有效。Woorons等人（《国际运动生理学与表现杂志》，2017年）证明了配合自愿低通气的重复冲刺训练显著改善了二氧化碳耐受力和运动表现。关键的辅助习惯包括日常生活中的鼻呼吸、缓慢呼吸练习和减少口呼吸——所有这些都能逐渐重新校准二氧化碳反应阈值。
Is breath-hold training safe? 屏息训练安全吗？
Breath-hold training is safe when practiced correctly on dry land in a seated or lying position. The most critical safety rule is never to practice in or near water without a trained safety buddy — shallow water blackout (sudden loss of consciousness from hypoxia) has caused many drowning deaths in breath-hold practitioners who trained alone in pools. Never push to complete oxygen depletion, and stop immediately if you feel lightheaded. The progressive approach in this guide — which avoids extreme holds and focuses on CO2 tolerance — is appropriate for healthy adults. People with cardiovascular conditions, epilepsy, pregnancy, or respiratory disease should consult a doctor.
屏息训练在陆地上以坐姿或卧姿正确练习时是安全的。最重要的安全规则是在没有训练有素的安全伙伴的情况下，切勿在水中或水边练习——浅水昏厥（因缺氧突然失去意识）已在独自在泳池训练的屏息练习者中造成许多溺水死亡事故。切勿将氧气耗尽至极限，一旦感到头晕立即停止。本指南中的渐进方法——避免极端屏息，专注于二氧化碳耐受力——适合健康的成年人。患有心血管疾病、癫痫、怀孕或呼吸系统疾病的人应咨询医生。
