Some researches for human health events based in extremely space weather period

By some experiments' verified, the ELF (extremely low frequency) can influence different levels of the organization of life, such as Biological membranes mast cells, endocrine glands cells and so on. The variation of geomagnetic filed may be a potential endanger factor for human health. In this paper, we will analyze the possibility of pre-alarming the human health events in extremely space weather period. And we will also advance some results of our researches such as the cardiovascular and cerebrovascular events, and Permeability of pleural effusion.
