I refer readers to this site
http://www.sunlight.heliohost.org/
for a history of sungazing and some interesting information on the role
of the retina and the pineal gland in detoxification and reversal of
aging.
I have experienced many of the effects discussed and I am starting to
conclude that my lead poisoning has taken me through a near death
experience. If you have a look at this site remember to distinguish
between "sun worship" which is idolatry that eventually results in
decay and decadence. eg Incas sacrificing children - not that I have
ever had the slightest inclination in that direction but history
reports that the Incas did. I don't understand how sunlight has been
involved in my conversion to Christianity but it seens it has and I am
still trying to come to terms with it. Perhaps the sunlight is linked
to the body's mechanism for removal of toxins like mercury and lead as
discussed on the site somewhere.

Food for thought and research.
cheers
