Pool Time
Should you fear the inviting cool blue waters of the swimming pool?
As we head into the season of lazy, hazy, crazy hours spent in and around the swimming pool, this is a good time to mention that the pool may not be the safest place to cool off.
Toxic tub
Every now and then we run an advertisement for a product called ShowerSafe, a showerhead filter that helps reduce the absorption of chlorine in tap water.
The latest ShowerSafe ad prompted this e-mail from an HSI member named Mary: “I read your article on chlorine and have a concern. I do water aerobics 3x a week for an hour. If a 10 minute shower is bad, what can that be doing?”
Good question. When I checked in with HSI Panelist Allan Spreen, M.D., and posed Mary’s question, he started at the top: the scalp, noting that the pores of the scalp are highly absorbent.
Dr. Spreen: “As someone who spent a TON of time in chlorinated water (and handling chlorine levels), there is NO question that swimming in American pools is far worse than showeringthe chlorine levels are much worse in the pool. That’s haunted me for years.
“Even worse, however, would be a hot tubthey are positively loaded with chlorine.
“I say ‘American’ pools, as in Europe they refuse to use chlorine or bromine, preferring the more expensive process of ozonation. My feeling is the US can’t afford to have that bit of news get out, as people will then start to question their municipal (chlorinated) water supplies.
“So, yes there’s scalp absorption (plus inhalation, don’t forget) in a shower. And never, ever, get in a hot tub unless it’s ozone treated (which you won’t find in the US, far as I know).”
Scar, paint, repeat
In the e-mail Dr. Spreen sent, he mentioned a book titled “Coronaries/Cholesterol/Chlorine” by Dr. Joseph Price. The book explains how chlorine intake contributes to narrowing of the arteries.
Dr. Spreen: “Price found that American kids dying in car wrecks at home had far less atherosclerosis than kids the same age killed in Vietnam. His conclusion was that the only thing different was all the chlorine tablets the troops had to dump into all water supplies to be able to drink available water over there.
“He then took chickens (which for some reason have arteries like humans) and tested chlorinated and non-chlorinated water on them. He found that the highly reactive nature of the chlorine molecule scars the arterial intima [the inner lining of the artery]. The body protects itself by painting a thin film of cholesterol over the damaged area. It’s not the cholesterol that kills, it’s the continual need for protection against the scars that eventually gets out of hand.”
Parallel rising
In “Coronaries/Cholesterol/Chlorine” Dr. Price offers another key point to support the link between chlorine exposure and atherosclerosis.
Dr. Prince notes that heart disease is a modern health problem. We’re told by mainstream nutritionists that high-fat diets are to blame, but high-fat diets were common in the 19th Century while heart disease was rare. Meanwhile, the steady growth of heart disease rates throughout the 20th Century parallels the steady increase in the use of chlorine in our water, paper, clothing, insecticides, paints and cleaning products.
Dr. Spreen tells me that “Coronaries/Cholesterol/Chlorine” is currently out of print, but a check on the Internet shows that copies are available through several online sources.
and another thing
Nutrition may play a key role in preventing and treating bedsores.
An HSI member named Terry writes: “I’ve tried to find info on bed sores. I saw some info somewhere about a study that used zinc, vitamin C and one othersomethingbut I don’t remember what it was. Do you know anything about this?”
There are several studies that have explored the importance of nutrition in coping with bedsores.
A 1988 study in the European Journal of Clinical Nutrition showed that patients with bedsores tended to have zinc and iron deficiencies compared to patients who didn’t have bedsores. And a study published in Lancet more than 30 years ago showed how a 150 mg daily supplement of zinc might improve healing in older subjects with bedsores. A more recent study in 1990 found that zinc oxide ointment applied topically improved healing when administered to patients with zinc deficiency.
Bedsores are also common among patients with vitamin C deficiency according to a study of patients with hip fractures at St. James University Hospital in the UK. Vitamin C supplements have been shown to promote faster healing in these cases.
Vitamin E applied topically has also been shown to help heal bedsores. And a 1993 study of malnourished nursing home patients with bedsores showed that a high-protein diet enhanced healing when compared to a low-protein diet.
