Ah summer – this wonderful season presents some unique conditions for our bodies to experience, including the arrival of a variety of insects that enjoy their yearly human feast and the increasing heat of the sun. As a result, the necessity for both bug bite and sun protection is greatly increased. Unfortunately, this often contributes to a rise in chemical and toxin exposure, that heightens our stress levels as our bodies cope with processing and eliminating them. For many people, the reduction of our exposure to chemicals and toxins is an important step in maintaining optimal health. Let’s take a look at what that means for summer time.
Bug Bite Protection
We explored our options for effective bug repellants and other preventative measures, last summer, so we’ll begin with a brief review:
Most commercial insect repellents contain a chemical called DEET, a registered pesticide. It is absorbed through the skin and passes into the blood. Most of the health concerns with DEET centre around the skin and nervous system with the potential of creating dermatitis and challenges with neuro-behavioural tasks requiring muscle coordination. There have also been case reports of associating DEET with seizures in children. This chemical also crosses the placenta, raising concern over it’s use by pregnant women.
With these possibilities in mind, Health Canada has phased out all insect repellants containing more than 30% DEET. In addition, Health Canada and the Canadian Pediatric Society advise against the use of DEET in children under 6 months of age. Solutions of up to 10% DEET applied up to once daily on children age 6 months to 2 years and up to 3 times daily for children up to 12 years of age has also been suggested by these groups. If you are choosing to use DEET containing products, follow these guidelines:
- Do not apply over cuts, wounds, or irritated skin.
- Do not apply to hands or near eyes and mouth of young children.
- Do not allow young children to apply this product.
- After returning indoors, wash treated skin with soap and water.
- Wear long sleeves and long pants and spray on clothing, as opposed to directly on skin. Wash repellent treated clothes as soon as possible or keep outside living areas to reduce exposure.
- Apply sparingly.
- Do not spray in enclosed areas and avoid inhaling
There are a number of effective, less toxic insect repellents available. They need to be applied more frequently than DEET based repellents, but they do not carry the same health risks. Many contain a variety of plant essential oils. Though safer for topical application to the skin, it is important to avoid the eyes and mouth when applying these products and be sure to keep them out of reach of children. In your back yard, use yellow outdoor light bulbs. They are less likely to attract insects. Use a fan outside when there is little wind – mosquitoes aren’t very strong flyers. When planning your gardens, plant mosquito repelling plants like lemon balm, catnip, basil and lemon geraniums around outdoor sitting areas. Also consider using bug shirts and hats as other nontoxic forms of protection.

Sun Protection
With the changes to our environment and the thinning of the ozone layer, protection from chronic skin damage by the sun’s rays has become more important to our health in recent years. There are two categories of sunscreen available: those that provide a physical block, like zinc oxide and titanium dioxide, and those that provide a chemical block, like PABA, benzophonones and cinnamates. With their make up of naturally occurring minerals, physical blockers work as a barrier against sun damage. Chemical sun blockers work by absorbing ultraviolet rays before they reach the skin’s surface. Over time, research has accumulated that suggests some of the chemical sun blockers possess hormone disrupting activity, specifically, mimicking estrogen. Other research suggests that as we rely heavily on the use of sunscreens, our vitamin D production, for natural immune and hormone balancing and cancer prevention, is reduced.
The Moral of the Sunscreen Story
Up to twenty minutes of sun exposure daily (just until your skin starts to turn pink) supports your natural vitamin D production. With any additional
time spent in the sun, protection from chronic sun damage of the skin is important. Explore sunscreens with more naturally based ingredients. The Environmental Working Group has completed a detailed assessment of thousands of sunscreens on the market and has compiled this information on their website: www.ewg.org/2010sunscreen. This wonderful tool can help you determine if the sunscreen you are using is causing more harm than good. Try searching your current sunscreen to see where it rates! Many of the best sunscreens listed (least toxic while still providing sun protection) are available at your local health food store.
I encourage you to practice healthful approaches to bug bite and sun protection. Make them part of the summer routine for the whole family. Your whole body will thank you and you will continue forward on your journey to health.
