Biophoton emission is the spontaneous emission of ultraweak light emanating from all living systems, including man. The emission is linked to the endogenous production of excited states within the living system. The detection and characterisation of human biophoton emission has led to suggestions that it has potential future applications in medicine.
An overview is presented of studies on ultraweak photon emission (UPE, biophotons) from the human whole body.
Electronic searches of Medline, PsychLit, PubMed and references lists of relevant review articles and books were used to establish the literature database. Articles were then analysed for their main experimental setup and results.
The, mostly, single case studies have resulted in a collection of observations. The collection presents information on the following fields of research: (1) influence of biological rhythms, age, and gender on emission, (2) the intensity of emission and its left-right symmetry in health and disease, (3) emission from the perspective of Traditional Chinese and Korean Medicine, (4) emission in different consciousness studies, (5) procedures for analysis of the photon signal from hands, (6) detection of peroxidative processes in the skin. Of each article the main findings are presented in a qualitative manner, quantitative data are presented where useful, and the technological or methodological limitations are discussed.
Photon emission recording techniques have reached a stage that allows resolution of the signal in time and space. The published material is presented and includes aspects like spatial resolution of intensity, its relation to health and disease, the aspect of colour, and methods for analysis of the photon signal. The limited number of studies only allows first conclusions about the implications and significance of biophotons in relation to health and disease, or to mental states, or acupuncture. However, with the present data we consider that further research in the field is justified.
生物光子发射是所有生命系统（包括人类）发出的超微弱光的自发发射。这种发射与生命系统内激发态的内源性产生有关。对人类生物光子发射的检测和表征表明，它在医学领域可能具有潜在的未来应用。
对人体全身超微弱光子发射（UPE，生物光子）的研究进行综述。
通过对Medline、PsychLit、PubMed以及相关综述文章和书籍的参考文献列表进行电子检索，建立文献数据库。然后对文章的主要实验设置和结果进行分析。
大多数为单病例研究，已形成一系列观察结果。这些结果提供了以下研究领域的信息：（1）生物节律、年龄和性别对发射的影响；（2）健康和疾病状态下发射强度及其左右对称性；（3）从中医和韩医角度看发射情况；（4）不同意识研究中的发射情况；（5）手部光子信号分析程序；（6）皮肤中过氧化过程的检测。每篇文章的主要发现以定性方式呈现，有用时会给出定量数据，并讨论技术或方法上的局限性。
光子发射记录技术已发展到能够在时间和空间上分辨信号的阶段。已发表的材料涵盖了诸如强度的空间分辨率、其与健康和疾病的关系、颜色方面以及光子信号分析方法等内容。研究数量有限，仅能就生物光子在健康和疾病、精神状态或针灸方面的意义得出初步结论。然而，基于现有数据，我们认为该领域的进一步研究是合理的。
