Prickly Heat?

Look for the words "noncomedogenic" on your sun block. That's made-up medical advertising talk for
"won't clog pores." Also, make sure you shower not only immediately after -- and I do mean
immediately -- but also before your ride.

How long did the itchy bumps last? Something similar occurs to me if I spend too much time in the sun but it's not prickly heat, it's an allergic reaction to the sun (similar to hives but not quite the same according to the doc) so I wear lots of sunscreen and take anti-histamines. Never had the problem until a few years ago and now I'm stuck with it. Mostly occurs at the beginning of the summer when I'm not used to being in the sun.

I went out for a 30 mile ride on Tuesday, put sunblock all over my arms and legs, pulled on a
Canari short-sleeved shirt and my Pearl Izumis, and went out at 0900 under the bright sun of North
Texas. That evening, I had red bumps all over my upper arms--between the shirt line and the top of
my shoulder. Boy, do they itch! I have been to the doctor with the result being diagnosed as
"prickly heat" or plugged up sweat glands on my arms....now, why didn't I get this on other areas
that were also covered up, such as my thighs or my ankles or my chest and back! Or, why that day
and not before that day?

The standard medical answer to fixing this? Stay in the air conditioning or the condition will come
back and get worse.

I am trying to figure out what to do next....wear a sleeveless shirt and no sunblock on the upper
arms? Wear a long-sleeved shirt? Change from a sunblock lotion to a gel?

Using a long-sleeved jersey and no sun-block on the arms sounds like the obvious thing to try. If
that works OK then maybe try other sunblock preparations to see if there's one that doesn't irritate
you. Maybe also try taking a shower before the ride.

So far, I still have the bumps after 7 days. My sunblock says it is "non-comedonic" on the label,
and this didn't happen on the other parts of my body where I put the same lotion. Nevertheless, I am
going to throw out that bottle and today not "wear" any sunblock. I just hope I don't get grilled
like a steak out there, though!

I had this happen a few years ago. I was told by a pharmacist to try using Stridex pads (acne
medication) on the bumps. It felt great and cleared up the bumps after a day or two.

I threw out the sunblock as I suspected it was the real cause of the trouble. I got new sun block &
the problem has never returned.

Give the stridex a try. --dc

A few years ago I noticed that I was developing dry irritated skin, and chronic sore throats. After
some investigation I found that a very harsh industrial grade detergent had been added to most
consumer cleansing products including shampoos, soaps, and tooth paste. The ingredient is Sodium
Laurel Sulfate.

See:

webdeb.comsls.htmOpen ↗

and

natures-domain.comsodium laurel sulfate.htmOpen ↗

There are many more sites documenting the use of this industreal detergent and its hazards
for body use.

After I switched to cleansing products without this chemical, my skin no longer was dry or itched,
and after three years of infection, my sore throat cleared up.

It may be that your skin has been so thoroughly cleaned by the soap that you are using that its
natural barrier to bacterial infection has been removed. Try some sodium laurel free shower gel,
such as Alba Botanica. 2-3 months of use should restore your skin to proper functioning.

It's a surfactant, of course it's used as an industrial detergent. Water is used in industrial
settings also -- is that dangerous?

The issue isn't all that simple. Yes, sodium lauryl sulfate is potentially irritating, but many of
the surfactants used as a substitute by "natural" products are even more dangerous, and some of them
are downright toxic and carcinogenic.

them are downright toxic and carcinogenic.

So, what is the point? Why slather it on and in your body if it is "potentialy dangerous", and in my
personal experience has caused extreme drying and irritation. According to a number of sources I am
not the only one to have experienced a reaction to this substance. Perhaps Pat in TX will find that
he can tolerate Sodium Laurel Sulfate, but why should he not be informed of the potential for
irritation?

As for water, why compare it to a surfactant, when water is neither acid nor alkaline and is not
likely to cause irritation? There is however a difference between chemicals designed for industrial
use and those intended for personal care. If any of this doesn't apply to you....ignore it.

periodically, my wife gets a deal on laundry detergent. If its the socks that get washed, up to my
ankles reacts, if a shirt, chest, back & arms, etc.

I can thank my Irish Ancestry for this. It seems my forbears evolved in a cool/cold cloudy
environment where the sun wasn't seen that much. i've discovered the modern day equivalent. My
genetics has predisposed me to this type of environment, which modern day translation is A Dark Air
Conditioned Bar.

I tried using a sleeveless Coolmax shirt and no sun-block on the upper arms as it was slightly
overcast and a bit cool after the thunderstorms the night before. I wound up with bright red upper
arms, but no bumps--well, no new bumps. In fact, I think the old bumps have flattened out. And, when
the red turns to tan, maybe my arms will all be one color. I am wondering if the tight band on the
short sleeves contributed to this problem. I noticed that some other people were wearing jerseys
with the band on the sleeves not being so constricted. OTOH, I liked wearing sleeveless, so maybe I
will go out and buy a new sleeveless jersey.

Thanks for the suggestions.....

I agree with this sentiment. It's probably worth looking into, but the reaction could be any of a
number of other things also. Somebody else suggested the dyes in the jersey. Various formulations
of sunblock might exacerbate the condition. I know somebody who breaks out in hives if he's in
contact with metal that has nickel in it. (ObCycling): I had a tough time cycling yesterday because
the high ozone level and the dust in the air shut down my windpipe. I avoid the Greenway in town in
the spring because of the high pollen levels from all the trees along the river can trigger an
asthma attack.

Water is used in industrial applications because it's a powerful solvent. A surfactant is used
to help lift the dirt. Just because SLS is able to foam up doesn't make it corrosive or
poisonous or scary.

Classifying something as acid or alkaline doesn't make it dangerous. Pickle juice is acidic and a
nasty eye irritant, but that doesn't make it dangerous.

Suggesting that SLS might be irritating to some people: that's fine. But I was responding to your
misleading scare-mongering of SLS as an "industrial detergent." The websites you posted about SLS
contain misinformation. The fact that 500 other websites parrot the same misinformation doesn't
make it true.

Several of them cite a study by a Dr. Keith Green on the potential eye damage that SLS can do. This
information came originally from a company called Neways, but now you see it all over the place. It
turns out Dr. Green and the Medical College of Georgia have threatened to sue Neways for defamation
over the issue, because Dr. Green's study on SLS showed that "eyes showed no irritation with the 10
dilution substance used. If anything, the animal studies indicated no risk of irritation
whatsoever." [1]

Several anti-SLS websites also quote an unreferenced _Journal of the American Journal of Toxicology_
report on the toxicity of SLS. It turns the _Journal_, Vol. 2, No. 7, 1983, has a report on a "Final
Report on the Safety Assessment of Sodium Lauryl Sulfate and Ammonium Lauryl Sulfate" which is a
review of dozens of studies that show that SLS and ALS are safe to use. There's nothing at all about
the stuff collecting in the skin, being irritation, or being dangerous. According to toxicologists,
the stuff is safe and non-irritating.

The websites you reference also make unattributed claims about SLS causing gingivitis, a downright
false claim that it's banned in Europe along with the silly supposition "that everybody in Europe
knows" that SLS is Bad For You, a totally fabricated MSDS, and ridiculous chemistry that's straight
out of science fiction.

Here's more information for anybody who's genuinely interested:
