prison damage two
Loss of light, air, views, workout time, ... loss of any ability to read, study, correspond, ...
Prison conditions clearly severely harming prisoner health and so then clearly illegal, also are not covered, please add to article; e.g. a summary as 
the 'hell block' in Oklahoma is entirely underground and intentionally built that way to deny all light to its prisoners and any doctor will make clear to anyone
this causes increasing major harm over time.
 Similar intentional aggravation are maximum security prisons with zero outside time e.g. as in 'old prison' prison yards; and claimed workout time of e.g. 30 minutes once week or once a month are also clearly a joke. And this is clearly illegal when solitary confinement exceeds few days, and times in solitary confinement of weeks, months, years are all massively illegal ...
 Restriction on any normal views - maximum security cells with no outside views or no windows or windows to high to see outside are all examples
of intentional torture vs older prisons all having a 'prison yard' where all prisons spent time outside 1-2 plus hours each day ... .
And this is also clear when all windows are covered to review all views with wire , twisted wires over each square inch - all psychological tortures.
And same with silence rules, etc.
