Your body gives off a tiny amount of visible (可見的) light. It’s too weak for the eyes to see. In fact, all living things emit (發出) very weak light. It’s thought to be a byproduct of biochemical reactions (生化反應). This visible light is different from the infrared radiation (紅外線) – a kind of invisible (不可見的) light – that comes from body heat. 人體會發出微弱的可見光,但太微弱我們肉眼很難看到。事實上,所有生物都會發出或多或少的微弱光芒——這種光和生化反應有關,與人體釋放的紅外線可不是一回事!
