3/6: However, it did find #daylight likely does have an impact on the composition of these communities. But there’s still a great deal to learn regarding the duration of exposure, intensity levels, ventilation, humidity, building materials, occupancy, microbial compositions, etc.

6/6: a) the nature of our interior #microbiomes, b) how various aspects of the building/occupant organism impact these #microbiomes, & c) the resulting impacts on human #health, we should proceed w/ caution when using such systems.
