在紧张时,我们最常出现的是呼吸加快,然后过度吸入氧气,过度吐出二氧化碳。二氧化碳呈酸性,在体内平衡酸碱比值,突然过度减少会使体液呈现碱性,引起呼吸性碱中毒,表现出眩晕、心跳加速等症状。过度换气多发生在紧张之后。紧张时身体需要更多的氧气,本来只需要深呼吸,但我们的肺已经习惯了浅而短的呼吸,它只能这样反应。 In times of stress, the most common thing we do is to breathe faster and then breathe in excessively and breathe excessively. Carbon dioxide is acidic, the balance of acid-base ratio in the body, a sudden over-reduction will make the body fluid showed alkaline, causing respiratory alkalosis, showing dizziness, rapid heartbeat and other symptoms. Excessive ventilation occurs after the tension. The body needs more oxygen when it is tense. It just takes a deep breath, but our lungs are accustomed to shallow and short breaths, and it can only react like this.
