太阳光线大致可分为可见光及不可见光。可见光经三棱镜后会折射出紫、蓝、青、绿、黄、橙、红颜色的光线（光谱）。红光外侧的光线，在光谱中波长自0.77μm至1000μm的一段被称为红外光，又称红外线。 红外线属于电磁波的范畴，是一种具有强热作用的[[电磁波]]。红外线的波长范围很宽，人们将不同波长范围的红外线分为近红外、中红外和远红外区域，相对应波长的电磁波称为近红外线、中红外线及'''远红外线'''。 红外线是一种光波，它的波长比[[无线电波]]短，比可见光长。肉眼看不到红外线，任何物体都发射着红外线。热物体的红外线辐射比冷物体强。<ref>[https://www.youlai.cn/ask/1031845.html 远红外线的作用],有来医生 , 2018年9月30日</ref>
