Indoor air condition may be involved to the health status_Among various factors in indoor air conditions, few reports were published concerning negatively chargedparticles. In this review, we detaile the biological effects of negatively-charged indoor air conditions, particularly on the psycho-neuro-endocrino-immune network. The short-term (2.5 hours) and mmedium-term (2 weeks) abidance of negatively-charged air particle dominant room resulted activation of natural killer cell activity induced by recurrent transient activation of interleukin 2. These results indicate that negativelycharged indoor air condition is better for immune status and may improve daily lives.
