Considering the widespread application of water-filtered infrared A (wIRA) irradiation in medicine, cosmetics, and wellness, we have conluded that the biological effects of this electromagnetic spectrum, ranging from 780 nm to 1400 nm, have become an important focus of experimental research. Two main effects of wIRA on single cells are discussed: thermal effects, caused by absorption of energy by cellular water and the aqueous medium surrounding the irradiated sample that result in warming, and supposed athermal effects that result from a direct interaction of wIRA with cellular molecules/structures excluding water. In the following, we discuss different experimental setups and highlight some cellular responses to thermal and athermal wIRA effects, as well as the experimental problems in differentiating between them.
鉴于水过滤红外 A（wIRA）辐射在医学、美容和健康领域的广泛应用，我们得出结论，该电磁光谱的生物学效应（范围从 780nm 到 1400nm）已成为实验研究的重要焦点。本文讨论了 wIRA 对单细胞的两个主要影响：热效应，由细胞水和辐照样品周围的水介质吸收能量引起的升温，以及假定的非热效应，它源于 wIRA 与细胞分子/结构的直接相互作用，而不包括水。在下面，我们讨论了不同的实验设置，并强调了细胞对热和非热 wIRA 效应的不同反应，以及在区分它们时的实验问题。
