The sickened human is something to be experimented with.

NASA astronauts have only managed to live continuously on the International Space Station (ISS) for a year and Biosphere 2 on Earth failed at two years of uninterrupted human habitation. Both cases required extracting the sickened people from the toxic environments. At this point it is ludicrous to talk about a permanent manned base on Mars.

The human skin evolved in a natural electromagnetic radiation environment and is now in a very unnatural man-made one that is making many people sick.

The human body when kept in an indoor environment of low lux light will not realize that it is daytime, as it cannot sense the increasing levels of daylight that the genetics are accustomed to. As such, by late morning your body may start sending a signal for you to sleep!

Ionizing smoke detectors unnaturally raise the background radiation levels in the human environment.
