Are Pillow Cases, Shower Curtains, and Diapers Harmful?


It’s not all that surprising that household cleaners, cosmetics and similar products contain potentially harmful chemicals. Yet, were you aware that some of your every-day, rather unobtrusive products may also contain those same harmful toxins that could adversely affect your health?

As reported last year in the journal, Environmental Health Perspectives, 55 potentially dangerous chemical compounds were detected in some unsuspected mainstream products such as pillow protectors, diapers, toothpaste, shower curtains, dryer sheets, and body wash. Some of these adverse effects include endocrine system disruption that is associated with asthma, poor development of the nervous system and slower metabolism, and a connection to increased cancer risks.

The interesting part about these chemical compounds was that they weren’t reported on the product label. In fact, products such as these do not have to come with a product ingredient label. In other words, if a chemical was added to your pillow protector, that chemical did not have to be disclosed on the label.
What’s more interesting is that this study also tested “alternative” products that were labeled as “green” or “natural” and still toxic chemicals were detected – although not nearly at the same concentration levels as traditional consumer products.

The research, which was presented at this year’s Annual American Public Health Associations’ conference in Boston earlier this month, found a wide range of phthalates, alkylphenols, parabens, and PCBs as well as flame retardants and some banned pesticides in the products that were laboratory tested. While some of the levels of these chemicals were low and tested within safe exposure ranges, the researchers noted that multiple products in the same home combined together may present unsafe exposures to these toxic chemicals.

Here is a run-down of these chemicals:
Phthalates are used in many plastic-type products to increase their durability and flexibility. When ingested or inhaled, they can cause problems with developing endocrine and reproductive systems. In particular, high levels of the phthalate known as DEHP have been linked with severe reproductive system development as well as obesity.
Alkylphenols are used ad additives for fuels and lubricants and are commonly used in the cosmetic industry. Of interest, the European Union has implemented restrictions on the use of alkylphenols because of the high toxicity. The chemical mimics estrogen and when in the system can be harmful to the reproductive system as well as immune system, especially in children.
Parabens are commonly used as a preservative in cosmetics. In small amounts as if often used in the cosmetic industry, these are harmful. However, higher doses and exposures to them has been linked to certain forms of breast cancer.
PCBs stands for Polychlorinated Biphenyls, which have been shown to cause a variety of health effects, in particular cancer. They have also been linked to disruptions in the immune system, reproductive system, nervous system, and endocrine system.
Antimicrobials are antibiotics that have become so ubiquitous that they are often ineffective against bacteria. The Centers for Disease Control reports that antimicrobials in products may not actually kill germs as intended because of our growing antibiotic-resistance to infections. The use of this chemical may be a moot point for its originally intended purpose, thus, leaving us at an increased risk for disease.

Probably the biggest take-away from the study was the need for improved product safety reporting measures. There is a huge push from environmental health experts for full product disclosure; the government is slow to respond. In the meantime, the best thing you can do is limit your exposure by using more natural products, or a lesser amount of mainstream products. Furthermore, you can always contact the company to request full disclosures of product ingredients.

Protect Your Eyes


Sight and sound are the two of the most dramatically affected senses when we age. According to a recent journal article addressing the physiology of aging, all sensory organs are affected when we age but the ears and eyes seem to be prone to the most reduction of ability.

From a physical standpoint, vision reduction is caused by the decline in elasticity of the eye’s lens, which means it struggles to focus incoming light and images. Hearing loss comes from a decline of sensory nerve cells in the ear. Both vision and hearing can affect stability and are both contributed to increased falls in older people. While both are important, the loss of sight might be prevented, depending on your behaviors.

Harvard Health identified six common vision problems, particularly among women, that occur when we age.

1. Presbyopia: This is a condition where the eye loses its ability to focus. General aging is the root cause of such a problem. Oftentimes, this is treated easily with bifocals, trifocals or reading glasses.
2. Cataracts: This condition occurs when proteins collect on the lens causing cloudy vision. Causes can be genetic, but also include diabetes, smoking and excessive exposure to the sun. The most common treatment is the surgical removal of the cataract.
3. Glaucoma: This occurs when fluid builds up behind the eyes and causes additional pressure and damages the optic nerve. General aging is a common cause, but it has also been linked to diabetes and heart disease. Medicated drops and/or surgery may be required as treatments.
4. Age-Related Macular Degeneration (AMD): This disease occurs when the macula (part of your eye) is damaged. The macula provides you with clear vision and its damage is often related to age or genetics. Smoking has also been linked to AMD.
5. Floaters: These are small specks or threads that “float” in your field of vision. It is caused when the vitreous humor (gel-like substances in your eye) shrink and create strands of collagen which float around within the eyeball. Surgery can remove them, but most people learn to live with them. They are typically not a sign of anything serious, except in very rare cases.
6. Dry Eye: This is when your eye cannot create enough tears for lubrication. It is often associated with hormonal changes in women, but can also be prompted by medications such as blood pressure drugs, antidepressants, and smoky or dry air. Effective treatments include eye drops, but sometimes surgery is necessary.


Tips to preserve your vision:

1. Wear sunglasses to prevent cataracts
2. Eat plenty of vegetables, especially those high in beta carotene such as carrots, squash, and sweet potatoes.
3. Eat plenty of omega-3 fatty acids such as fish and flaxseeds
4. Don’t smoke, or quit if you already do smoke. This significantly reduces your risks of cataracts and AMD.
5. Try not to stare at your computer or TV screen. Looking away can give your eyes a break and reduce strain.
6. Get your eyes checked at least annually.
