Dangerous Household Ozone Generators

Last month I looked up information about in-home ozone generators. A friend of mine was thinking of buying a house in Arizona (she bought it), and the sellers were using indoor ozone generators. The ozone gave my friend a severe headache and caused her blood pressure to rise to dangerous levels. (She takes blood-pressure medication and had to increase the dosage after inspecting the house.)

I rushed to my computer and found quite a few useful websites, and, yes, ozone causes headaches, high blood pressure, sore throats and coughs (see Effects of Ozone Pollution on Seniors and Ozone Generators May Be Dangerous to Your Health). Ozone irritates the lungs, exacerbates lung disease, accelerates aging, and damages home electronics and wiring. In combination with air fresheners or household disinfectants, ozone will produce formaldehyde, a chemical that can cause cancer (see Study Warns of Cleaning Product Risks). The California Department of Health Services began warning consumers about indoor ozone generators back in the 1990s. And Health Canada says, “If you have an ozone generator in your home, stop using it.”

Take a look at these web pages, too:

Beware of Advice from Meetup.com Members

If you join a Meetup.com activity, let’s say a hiking group, and you hear the members giving out impromptu advice regarding survival, health, injury, etc., make sure you consult a professional, too, or at least do some reading.

You might find that at a monthly hikers’ meeting, an attractive know-it-all is showing you a stretching exercise for your sore knee. But if you go to a good physiotherapist, you might learn that the stretching will only exacerbate your knee or hip injury, that what you really need to do is build muscle strength in the injured area.

Similarly, someone might tell you that no one dies from rattlesnake bites and that the Mojave Rattler is no more dangerous than a Diamondback. However, if you take the time to read page 583 in A Natural History of the Sonoran Desert (Arizona-Sonora Desert Museum) you will find that world-renowned experts write, “The Mojave has a very toxic venom that has caused human fatalities.”

Here’s couple of good (but brief) desert survival books:

Calcium

If you are unable to eat milk products or if you are taking a medication such as prednisone, you should definitely take calcium supplements — at least 1000 mg of calcium per day, divided into 2 to 4 doses. Never take more that 500 mg of calcium at one sitting during the day: your body has a hard time utilizing more that 500 mg at a time. And I have heard that among people supplementing with calcium, cranberry juice causes kidney stones. So avoid cranberries.

You might want to take a look at EZorbOnline.com. EZorb is a “new generation” calcium supplement — it has a very high absorption rate. I believe that I can feel the effects of EZorb on my muscle tone and skeletal strength.

The manufacturer states that “EZorb does not need participation of Vitamin D or magnesium for better calcium absorption,” but I still take 1000 IU of Vitamin D every day, and I continue to include old-style calcium-magnesium-zinc supplements in my daily regimen.

Recent research shows that while supplementing with calcium, you should take 1000 IU of Vitamin D every day. The old standard was 400 IU, but now it’s 1000 IU.

Desert Venom

Although a number of medical professionals still recommend applying a tourniquet to rattlesnake bites (and then briefly releasing the tourniquet every 15 to 20 minutes), Tony Nester, the author of Desert Survival Tips, Tricks, & Skills (Flagstaff: Diamond Creek Press, 2003), writes that most of the doctors he spoke to advise against applying a tourniquet (it simply concentrates the venom in the tissues immediately adjacent to the bite). Your best treatment is to get to a hospital or clinic as quickly as possible: do not delay.

Nester says that two important rules of desert living are 1) “Don’t put your hands where you can’t see” and 2) “Vigorously slam your boots on the ground and shake clothes before you put them on.”

Watch out for Gila Monsters, Africanized Bees (Killer Bees), Black Widow Spiders, Scorpions, Rattlesnakes, and Coral Snakes. Wear sturdy hiking shoes or boots. Do not hike alone. Carry a cell phone, an ultralight emergency blanket, snacks and at least two liters of water. Always let a friend or neighbor know where you are going and when you expect to return.

Mesothelioma and Asbestos Information

We often hear of opportunists building rather shallow web sites around mesothelioma and asbestos so that they might obtain top dollar from contextual pay-per-click Google Adsense advertisements (Google crawls participating web sites and serves ads that match each site’s content). Or the myth is that content related to mesothelioma will bring webmasters some of the best paying Google Adsense ads.

The mesothelioma information site, www.mayoclinic.com/health/mesothelioma/DS00779, tells victims and victims’ families (and other interested parties) all about mesothelioma: what it is, how and why individuals fall victim to the disease, and the symptoms and procedures leading to diagnosis. The writers go on to point out the products that contain asbestos and the jobs that lead to asbestos exposure, and provides links to cancer centers that treat individuals suffering with mesothelioma. Available treatments (including nutritional and alternative therapies) are enumerated and explained.
