什么决定了我们能憋气能憋多久?通常的分析认为,这受制于大脑对氧气的需求,但实际上,通常早在大脑或身体消耗完所有氧之前,人就会喘气。这个问题困扰了科学家数十年,现今科学家也许已经接近了答案。
What determines how long we can hold our breath? The usual analysis holds that this is governed by the brain’s need for oxygen, but in fact people usually pant if it is long before the brain or body has exhausted all the oxygen. This problem plagued scientists for decades and now scientists may be approaching the answer.
