摘要
环境光照作为重要的授时因子,对多种生理和心理功能存在广泛影响,其对情绪的非视觉作用尤其引起研究者们的关注。研究发现,环境光照的照度、色温和波长均是影响情绪的重要物理因素;短光周期、夜间人工光以及持续光照/黑暗等异常光照模式则会导致情绪障碍;光照的情绪效应还受到光照时长、时间点、个体特征、主观偏好及基因类型等的调节。光照作用于情绪的路径主要包括两个方面,一方面视网膜中的内在光敏感神经节细胞将光信号投射至情绪调节相关脑区直接影响情绪;另一方面光信号通过同步内部生理节律及其调节下的激素分泌、神经传递和睡眠间接影响情绪。未来研究考察短时光照的视觉功效时需要采用更客观多样化的情绪测量技术,综合非视觉与视觉作用路径深入对比健康与情绪障碍群体的差异性。
Ambient light broadly modulates individuals’physiological and psychological functions as a zeitgeber,and its non-image-forming(NIF)effects on individuals’mood attract wide attention recently.Previous studies have demonstrated that illuminance,correlated color temperature,and wavelength are key physical factors influencing mood.Unusual light patterns such as short lighting periods,artificial lighting during the night,and constant lighting or darkness may lead to affective disorders.In addition,the NIF effects of ambient light on mood are also modulated by exposure duration,timing,individual characteristics,subjective preferences,and gene types.The potential mechanisms that underlie the modulatory effects of light on mood are discussed from two aspects:on the one hand,the intrinsically photosensitive retinal ganglion cells may project light signals to the brain areas responsible for emotional regulation.On the other hand,ambient light may regulate mood by altering circadian rhythms,hormone secretion,neurotransmission,and sleep.Future efforts are necessary to address the effects of short-term light exposure on mood by introducing more objective and diverse emotional measurement techniques,integrating visual and non-visual neural pathways,and further exploring the therapeutic effects of light among people with mood disorders.
