Hypomagnetic fields (HMF), that is, the elimination of the geomagnetic field (GMF), are a risk factor to the health of astronauts in outer space. It has been established that continuous HMF exposure affects cytoskeleton assembly, cell proliferation, embryonic development, and even learning and memory. In addition, although there were some previous studies that focused on the effects of long-term HMF-exposure, so far very limited investigations have been conducted to examine the short-term HMF effect in animals. In this study, we exposed adult male C57BL/6 mice to a 3-axis Helmholtz-coil HMF-simulation system for 72 h and found that short-term HMF-exposure induced a significant increase in anxiety-related behaviors. And our findings provide important information for both psychological intervention and the health care of astronauts. Bioelectromagnetics. 40:27-32, 2019. © 2018 Wiley Periodicals, Inc.
低磁场（HMF），即地磁场（GMF）的消除，是外层空间中宇航员健康的一个风险因素。已经确定，持续暴露于HMF会影响细胞骨架组装、细胞增殖、胚胎发育，甚至学习和记忆。此外，尽管之前有一些研究关注长期暴露于HMF的影响，但迄今为止，针对动物短期HMF效应的研究非常有限。在本研究中，我们将成年雄性C57BL/6小鼠暴露于三轴亥姆霍兹线圈HMF模拟系统72小时，发现短期暴露于HMF会导致焦虑相关行为显著增加。我们的研究结果为宇航员的心理干预和医疗保健提供了重要信息。《生物电磁学》。40:27 - 32，2019年。©2018威利期刊公司。
