Do Toxic Homes Cause Asthma?

Note: Today’s blog entry was written by Dr. Stephen Chaney. Dr. Chaney is a professor of biochemistry, biophysics and nutrition at UNC Medical School in Chapel Hill, North Carolina. He is also a prominent cancer researcher with a well established research lab he directs at UNC.


Everybody is going green. Biodegradable cleaners are finally in fashion.

But did you realize that many of the cleaners that you buy in the supermarket - and some of the biodegradable cleaners that you buy in the health food store - release toxic fumes in your home that can adversely affect the health of you and your children?

I'm going to focus on just one aspect of this topic - household chemical exposure and childhood asthma.  But first a bit of background information: The prevalence of childhood asthma increased 74% between 1980 and 1994 and has continued to increase in the years since.

The causes of this rapid increase in asthma prevalence are likely to be complex, but evidence has accumulated in recent years that some of the increase may be caused by early exposure to toxic chemical fumes in the home.

Why is that?

The American consumer keeps demanding cleaners that work better (It's considered a big plus if they require no effort) and are easy to use (Don't bother with messy liquids and pastes - just spray it on).  And manufacturers have been willing to oblige by adding ever more exotic chemicals to household cleaners and putting them in aerosol spray cans.

And of course no one opens their windows any more. That would be wasting energy and contributing to global warming.

The result is that these toxic chemicals accumulate in the air that we breathe in our own homes. In fact, the Environmental Protection Agency has stated that the air inside our homes is often more polluted than in Los Angeles or New York on a smoggy day.

A number of studies have pointed to an association between these toxic household fumes and childhood asthma, but I'd like to focus on one particularly good study on this topic that was published recently in the European Respiratory Journal (31: 54-57, 2008).

This study measured the household chemical exposure of 7,162 pregnant women in England and looked at the incidence of asthma in their children at age 8.5 years.

A maternal composite household chemical exposure (CHCE) score was derived by measuring the pregnant mother's exposure to a number of common household products known to contain toxic chemicals.

The household products used most frequently were disinfectants (87.4%), bleach (84.8%), aerosols (71.7%), air fresheners (68%), window cleaners (60.5%), carpet cleaners (35.3%) and pesticides/insecticides (21.2%). (For information on the toxic chemicals in these and other common household products visit:  http://www.householdproducts.nlm.nih.gov/products.htm)

Asthma was quantified based on persistent wheezing (reported by the parents) and several lung function tests that were administered at age 8.5 years.

To make sure that the asthma was not caused by simple allergies the children were also given a skin prick test against a panel of 6 common childhood allergens (house dust mites, cats, mixed grass, mixed nuts, peanuts and milk).  The study also controlled for confounding variables such as exposure to tobacco smoke, damp housing, pets in the home and maternal history of asthma.

In short, this was a very large and particularly well controlled study.

And the results were clear.  Higher household chemical exposure during pregnancy was associated with a 41% increase in childhood asthma in children with no known allergies.

What does that mean to you and me? It means that it is not enough to select household products that are safe for the environment.  We also need to select products that we use in our homes on the basis of their safety for us and our family - not just on the basis of cost and convenience.

To Your Health!

The Health Case for Reforming the Toxic Substances Control Act: Executive Summary


This a compelling new report put out last week by Safer Chemicals Healthy Families.  It created quite a stir in the media so I wanted to be sure my readers had a chance to read it for themselves and take action.  If you are tired of the governments lack of concern regarding the dangers of toxic chemicals in our homes, speak up on behalf of chemical reform by adding your name to the Safer Chemicals Healthy Families campaign.

The Health Case for Reforming the Toxic Substances Control Act: Executive Summary

There is growing agreement across the political spectrum that the Toxic Substances Control Act (TSCA) of 1976 does not adequately protect Americans from toxic chemicals. In the 34 years since TSCA was enacted, the EPA has been able to require testing on just 200 of the more than 80,000 chemicals produced and used in the U.S., and just five chemicals have been regulated under this law. Environmental Protection Agency (EPA) Administrator Lisa Jackson has asked Congress to provide her agency with better chemical management tools for safeguarding our nation’s health.[1]




Much has changed since TSCA became law more than 30 years ago. Scientists have developed a more refined understanding of how some chemicals can cause and contribute to serious illness, including cancer, reproductive and developmental disorders, neurologic diseases, and asthma.



The Safer Chemicals, Healthy Families coalition believes that, by reforming TSCA, we can reduce our exposure to toxic chemicals, improve our nation’s health, and lower the cost of health care. This report documents some of the scientific findings and economic analysis underlying our position.



Chronic disease is on the rise

More than 30 years of environmental health studies have led to a growing consensus that chemicals are playing a role in the incidence and prevalence of many diseases and disorders in our country, including:



•Leukemia, brain cancer, and other childhood cancers, which have increased by more than 20% since 1975.[2]

•Breast cancer, which went up by 40% between 1973 and 1998.[3] While breast cancer rates have declined since 2003, a woman’s lifetime risk of breast cancer is now one in eight, up from one in ten in 1973.[4]

•Asthma, which approximately doubled in prevalence between 1980 and 1995 and has stayed at the elevated rate.[5][6]

•Difficulty in conceiving and maintaining a pregnancy affected 40% more women in 2002 than in 1982. The incidence of reported difficulty has almost doubled in younger women, ages 18–25.[7][8][9]

•The birth defect resulting in undescended testes, which has increased 200% between 1970 and 1993.[10]

•Autism, the diagnosis of which has increased more than 10 times in the last 15 years.[11]

The health and economic benefits of reforming TSCA

According to the U.S. Centers for Disease Control and Prevention (CDC), 133 million people in the U.S.—almost half of all Americans—are now living with these and other chronic diseases and conditions, which now account for 70% of deaths and 75% of U.S. health care costs.[12]



Estimates of the proportion of the disease burden that can be attributed to chemicals vary widely, ranging from 1% of all disease[13] to 5% of childhood cancer[14] to 10% of diabetes, Parkinson’s disease, and neurodevelopmental deficits[15] to 30% of childhood asthma.[14] Whatever the actual contribution, effective chemical policy reform will incorporate the last 30 years of science to reduce the chemical exposures that contribute to the rising incidence of chronic disease. And any decline in the incidence of chronic diseases can also be expected to bring health care cost savings. Even if chemical policy reform leads to reductions in toxic chemical exposures that translate into just a tenth of one percent reduction of health care costs, it would save the U.S. health care system an estimated $5 billion every year.



The U.S. now spends over $7,000 per person per year directly on health care.[12] This sum does not include the many other kinds of costs, such as the costs of raising a child with a severe learning disability or coping with a young mother’s breast cancer diagnosis. Chemical policy reform holds the promise of reducing the economic, social and personal costs of chronic disease by creating a more healthy future for all Americans.

Health Benefits of a Good Laugh


Watch Out!  It's Contagious!
 A joke can be good in more ways than one.  Laughter is actually powerful medicine that my even help prevent heart attacks, according to a study performed by cardiologists at the University of Maryland Medical Center.

Their study evaluated healthy individuals and people with heart disease.  They found that the people with heart disease were 40 percent less likely to laugh in a variety of situations than their healthy counterparts of the same age.  Humor alleviates stress and tension, and patients with mental stress often have other impairments of their blood vessel linings.  The cardiologists speculate that the resulting inflammatory reactions may lead to a fat and cholesterol buildup in the arteries and ultimately to heart disease.

The benefits of laughter extend far beyond the heart, too.  Laughter releases endorphins, causing a feeling of elation.  Laughter also increases blood oxygen levels, which is beneficial for healing, improving circulation and easing headaches.  Hearty laughter massages the heart, lungs and digestive system.


For a healthy heart, body and soul, eat right, exercise and...laugh!

Required, Desired, Inspired!




This blog post is from my friend and business associate, Jennifer Harvey.  She has some wonderful insights about setting daily goals that I thought you might enjoy.  Jennifer also makes a plug for exercise and improving health.  If I can help you in those areas, please let me know.  Happy New Year!


My 2010 mantra – Required, Desired, Inspired!

I was on the elliptical the other day. It took all I had just to get on the darn thing. I just was not in the mood. I said to myself just get 15 minutes in. That’s all I require today – just 15 minutes. I can do that. About 10 minutes in I felt better and felt I could make it more than just the 5 minutes I had required of myself. So I reset my expectations to 18 minutes and increased my pace. Ah, I can make it past my required time to my new desired time I thought. At 17 minutes I was feeling inspired and felt I could push it up a notch and go to 20 minutes. I did it. I took that work out from required to inspired.

I have now started setting my day with a REQUIRED goal, a DESIRED goal and an INSPIRED goal. Now the idea hear is not to make INSPIRED too easy so if I am hitting INSPIRED too regularly it’s time to make that the new REQUIRED.

Obviously I would like to push to INSPIRED as often as possible but some days I just don’t feel inspired and ‘required’ is an accomplishment in and of itself.

Everyone has their own motivation techniques. This is a new one I developed and am trying out. Since I just thought it up while working out a few days ago I felt with the new year it would be a perfect way to implement this new plan.

I’m not really setting a New Year’s resolution. I’m already on a path of improving my health by exercising and making better food choices. All I want to do is stay on the path, take each day as it comes and make time to enjoy the journey.

Exercise makes me feel great mentally and physically. It improves my appearance and therefore, self esteem. It relieves stress and releases toxins from the body. I can enjoy the occasional bad food choices without guilt because I know I can burn it off through exercise. I believe exercise is the magic bullet, the key to long lasting health and happiness.

I will turn 40 in 2010 and my oldest son will graduate from high school and start college. It’s going to be a big year and I can’t wait.

Bring it on!

Tune Up Your Immune System



Note:  Today’s blog entry was written by Dr. Stephen Chaney. Dr. Chaney is a professor of biochemistry, biophysics and nutrition at UNC Medical School in Chapel Hill, North Carolina. He is also a prominent cancer researcher with a well established research lab he directs at UNC.



Many of you have been saying to me: "All I hear about in the news is shots and drugs. Is there a holistic approach for strengthening my immune system?"


My answer is yes! Here are my suggestions:
1) Start by eating a balanced diet composed of whole, unprocessed foods without a lot of fat and simple sugars. A great place to start designing a balanced diet that is perfect for your age, gender and activity level is www.mypyramid.gov.


2) Get plenty of sleep. The experts recommend 8 hours of sleep a night, but a majority of Americans get far less than that.

3) Exercise on a regular basis. Both too little and too much exercise can weaken the immune system (You might have guessed that the problem for most of us is the "too little", not the "too much"). The experts recommend at least 30 minutes every day.


4) Maintain ideal body weight. Those excess pounds really zap our immune system.


5) Minimize your reliance on medications. Many common medications weaken the immune system (Just listen to the disclaimers in the TV commercials for examples).


But you must work with your physician on this. Once your physician knows that you are willing to take personal responsibility for your diet and lifestyle, they will generally be willing to minimize the number of medications that they prescribe.


6) Focus on the positive. Studies show that optimists are healthier and live longer than pessimists. And the good news is that anyone can cultivate an attitude of optimism. For most of us it is a lifestyle choice - not something that we were born with.


7) Add a supplement program to assure that your immune system is functioning optimally. In the ideal world supplements wouldn't be necessary, but there are very few "saints" who do a great job in all 6 of the areas that I mentioned.


A well designed supplement program fills in the "gaps". We want to make sure that we are getting adequate:


  •  B vitamins and protein because our immune cells need to divide very rapidly when we have immune challenges.
  • Antioxidants because our immune cells create lots of free radicals.
  • Trace minerals, especially iron and zinc, because they are required by important enzymes of the immune system.
  • Vitamin D because it is vitally important for a strong immune system and most of us are not getting enough.
  • Probiotics (healthy bacteria) because "bad" bacteria and yeast in our intestines can weaken the immune system.
  • Omega-3 fatty acids to modulate the immune system once it has taken care of the invading bacteria or viruses.
We don't need megadoses. We just need enough.


One final thought: A holistic approach to strengthening our immune system is not an "either - or" proposition.


The flu shot is 66% effective in preventing the flu for people with a strong immune system and only 33% effective in preventing the flu for people with a weak immune system.


To your health!
