科学家发现学生的体积随呼吸而变化,可能会影响视力和诊断神经问题。 Scientists find pupils change size with breathing, potentially impacting vision and diagnosing neurological issues.

科学家发现,我们的瞳孔与呼吸同步变大, 吸入时瞳孔最小, 呼出时最大. Scientists discovered that our pupils change size in sync with our breathing, with the pupil being smallest during inhalation and largest during exhalation. 这一现象在五个实验的200多名参与者中观察到,无论照明、焦点距离或精神努力如何,这种现象持续存在。 This phenomenon, observed in over 200 participants across five experiments, persists regardless of lighting, focus distance, or mental effort. 瞳孔大小的周期性变化可能会影响我们的视力, This cyclical change in pupil size could affect how we see and may help diagnose neurological conditions.
