[net.med] Let's talk about sunburn

ajs@hpfcla.UUCP (07/05/84)

Let's talk about sunburn a minute...

As a recent  victim, I've been pondering a few questions on the subject.
Everyone  knows that UV  exposure  is bad for pale skin in the long run,
and that  tanning is an adaptive  attempt to reduce the  damage.  What I
am wondering is...

* Do people with naturally dark skins suffer any long-term  effects from
  UV exposure, or are they completely immune to problems?

* Does a dark tan fully protect the skin, or just reduce the damage?
  If the latter, how much?  (A lot, or a little?)

* Is the process of slowly  acquiring a dark tan (by limited  exposures)
  as bad as  anything  else, or is it in fact a healthy  thing to do, if
  you are going to spend time in the sun?

* Is it true that the worst  effects of sunburn  may be due to an excess
  of vitamin D, and, if so, is there anything you can do about it, other
  than avoid that vitamin for a few days?

* Once you are burned, what REALLY  works to (a) reduce the pain and (b)
  reduce the peeling?

If this is a subject of popular interest, please post your responses.

Thanks,

Well, two general comments.  First of all, use of aspirin can significantly
help sunburn, both in reducing pain and in speeding the healing.  I
don't know the exact reasons why it helps the healing, but I know
from experience that it does work.

The other thing that I've learned from experience is that if you take
large doses of PABA for a few weeks, you are less likely to burn
when exposing yourself to the sun for any length of time.  PABA is
the same stuff they put in sunblock cremes that you'd normally rub
all over your bod.  It also is a vitamin you can get at your local
vitamin emporium.

The above are personal observations and are not to be construed as
informed medical advice.

	What I know about sunburning-

	People with dark skin probably suffer less damage because
less of the UV rays get thourgh their skin. But a good tan on any-
one is a sign of skin damage and that is all. It is your skin's way
of minimizing future extreme damage(sunburn). Some doctors believe
that a tan(like the real dark ones that have become increasingly
popular) is just as or more dangerous than a surburn. You don't
feel bad, you look good, but in the mean time you're killing your
skin. Tanning ages your skin. It makes it lose its elasticity. 
Overall, it's just not good for you. 
	For a long time doctors believed that the only dangerous
type of UV ray was the type that burned you. And the type that
tanned you were safe. So lots of tanning salons showed up because
they are able to screen out all the bad rays, and only bombard
their customers with the tanning rays. Well, the doctors are starting
to change their minds. Some have gone so far as to say that the 
tanning type are worse for you(probably because they do more long-
term damange and give you a sense of safety because you're not
burning.
	So, for your skin's sake, don't go out without some sort
of protection, even if you do have a tan. When I was in college
I used to lay out in the sun all the time. Now I'm very careful.
I hate getting a surburn(aloe is the best relief, look for some
thing that is close to 100% aloe gel) and I hate peeling(once it
starts, there is nothing you can do; moisturizers are helpful
only before you get burned or tanned).
	Hope this helps you some.

I grew up in Florida.  There was a tremendous peer pressure to be tanned.
Being fair skinned it was annually a painful experience for me.  I've also
learned recently that those summer overexposures are still affecting me, in
the form of skin problems of (so far) noncancerous types.  Believe me, over
exposure to sun is a bad idea.  How much exposure is injurious is dependent
on your skin type, but you won't know for years whether you've overdone it.
And then it's too late.  I have only anecdotal knowledge of the effects on
health of sun exposure, but I've never heard of anyone whose health was
improved by being exposed to the point of sunburn.  I've certainly heard
of lots of cases where the opposite was true.  In addition to the immediate
pain, I've seen cases of pigmentation disorders (permanent unsightly brown
patches), allergic reactions, scar tissue formation, and of course, skin
cancer.  <FLAME> The pressure to turn your skin brown is a prime example 
of Madison Avenue hype which has been swallowed by our society.  The people
promoting it should be prosecuted. <FLAME OFF>  

To answer your specific questions: Dark skinned people can also burn,
particularly in sensitive areas like the lips, nose, and ears.  A tan
is effective only in preventing immediate sunburn, but probably not in
reducing long term effects.  I have no idea what Vitamin D has to do with
it, and I suspect no one else does either.  Ointments containing PABA are 
effective antiburning agents.  Once burned, aloe is effective in reducing 
pain, and, if applied promptly, may be helpful in preventing peeling 
(although this is dependent on how badly you've burned, and I have no
conclusive evidence that it is true at all.)

I happen to be somewhat fair-skinned, and growing up in Texas, I
had a chance to learn quite a bit about sunburn(s). Obviously,
prevention is the best medicine, but an old "home-remedy" that
has always worked for me is to apply white vinegar to the burn.
It takes away the pain and often prevents peeling. Why ? I
haven't the foggiest idea, but it seems to work nonetheless.
In fact, I got quite sunburned on the 4th (gee... Yankee sun
can burn you too  :-)  ) and used vinegar to ease the pain,
although I did peel this time.

One caveat... I remember some people warning that it would
"toughen up" your skin, whatever that implies (us guys are
fairly lucky, in that tough, weather-beaten, leathery
skin is seen as desirable and macho in some circles :-) ).
Also, I wouldn't reccommend going out immediately
after using the vinegar...  you'll smell like a salad.  :-)

p.s.	Some people I know used to apply it with cotton balls,
	but I use a spray bottle --- it's much easier.

With respect to PABA: Yes, this can help if taken internally, but realize
that most of the stuff is NOT in your skin and thus isn't protecting it.
There are sunscreens which consist mostly/entirely of PABA and alcohol,
and when I was rock-climbing that was all I would use.  Occasionally I
would get sloppy and notice hours later that I had burned badly in a small
area of skin that I had neglected to cover!  And unlike most other sunscreens,
PABA is completely nontoxic.

With respect to aloe vera: Sure you can buy it in the store, but why not
grow your own?  Aloes make wonderful house plants since they can tolerate
a wide variety of temperatures and light levels (don't let them get too
cold though), and grow rapidly.  One or two small to medium plants will
supply enough leaves to deal with the average number of burns and sunburns
in a 2-person household.  You can either pull off the bottom leaf, or keep
them in the refrigerator for a few weeks after they fall off.  To use, split
the leaf the long way, and squeeze the gel out or rub the cut surface on the
burn.

Also note that aloe is useful on ALL burns (except those where the skin is
broken), not just sunburns.  And, for me at least, it seems to ease the pain!
