	Well when possible that is fine.  When I was younger I pursued
physical activity.  After I was in my 46th year that became impossible
and now at 79+ I am barely able to ambulate and carry home a few lbs
of food which I must then find the energy to cook.  I also have had
injuries or simple wearing  out of joints to contend with.

I don't have any trouble watching TV then 
falling asleep (or reading on a tablet or 
whatever).  My trouble is that I wake up after 
about 4 hours and the reason for that is 
something that I don't think changing light 
bulbs is going to fix.

There's something decent to watch on TV???   Wow!

There was an article about this recently - think it was probably in the
AARP magazine.    My wife bought a clock-radio some time ago, with the
large (~3 inch) 7-bar display (she can't see well without the glasses).
The display was a greenish-blue, rather than the more common orange or
red.  It lasted about two weeks before it was sent to Good-Will.  The
replacement is the same size, but red, with the intensity set to low.

Hah!  They can have it.  Now I have scientific justification for my
hatred of the blue-LED craze.  (Aside from my eyes' inability to
focus on those wavelengths.)

There exist programs to do this automatically at night (using the
system clock) Right now I cannot remember the name of any of them.

I had it running on my system for a while and then forgot about it.
Probably on there somewhere still.

	f.lux is referred to in the URL I posted but it is not compliled
for my OS so I simply went to the simplest (for me) correction.
	Back in my early Amiga OS days I regularly messed with color settings 
to off the overscan/interlace settings I used.

Not sure what you mean by "not compiled for my OS?

It is apparently a pre-compiled (ie not open source) program. It uses
randr to adjust the screen colour temperature at appropriate times of
the day, as defined by your location on earth.

I use redshift/redshift-gtk. Does make the screen much less annoying
to use.

I don't have much trouble with monitors.  It's all those gratuitous
brilliant blue LEDs (many of them flashing) which manufacturers insist
on putting on everything these days.  Once when I was doing sound for
a play, the board's pilot light was a blue LED that was so bright that
I had to cover it with three layers of masking tape so that I could
see anything else in the darkened hall (including the board itself).

	Herman did you read the article?
	Not a newspaper story but a report on research.
  	
	Oh well you are probable a young fellow and think that you are supposed 
to be awake half the night punching your keyboard.

	Placebos work for various reasons and one is that most conditions are 
self-correcting especially when young.  Some conditions
do not self-correct and that is when you need medication of some
kind.  Other sorts of conditions self-correct with age and experience
if you have some regard for your body, eat, rest and sleep in 
appropriate amounts, you generally get over them.

Yes, I did. And I am not impressed by it. Not by it contents and not by the 
references I find on those studies.

73 years young, yes, and I tend to go to sleep around midnight after 
switching off some screen (TV, tablet, laptop)
