Savannah Sidewalks: Sun Lies Inflating Summer Fat?
By Franklin Everett ShawThe sun beats down, reflecting harshly off the pale sidewalks. It’s a familiar scene in Savannah, Georgia, especially during the summer months. But beyond the picturesque charm of the Historic District lies a hidden danger: the amplified ultraviolet (UV) radiation bouncing off those very sidewalks, silently accelerating skin aging and increasing the risk of skin cancer for unsuspecting pedestrians.
Savannah’s unique environment intensifies this risk. The city’s latitude places it closer to the equator, resulting in higher baseline UV exposure. The prevalence of light-colored concrete and brick sidewalks, particularly in the Historic District, acts as a reflector, significantly increasing the amount of UV radiation reaching pedestrians.
This isn’t just about a tan. It’s about the cumulative effect of daily UV exposure, amplified by reflective surfaces, leading to premature wrinkles, sunspots, and, more seriously, skin cancer.
So, how can Savannah residents and visitors protect themselves? It requires a strategic approach, combining the right sunscreens, clothing, and timing.
First, sunscreen is non-negotiable. But not all sunscreens are created equal. Look for broad-spectrum protection, meaning it shields against both UVA and UVB rays. UVA rays are primarily responsible for skin aging, while UVB rays cause sunburn and contribute to skin cancer.
A Sun Protection Factor (SPF) of 30 or higher is recommended. SPF indicates how long it takes for UVB rays to redden your skin compared to not wearing sunscreen. For example, SPF 30 allows about 3% of UVB rays to reach your skin.
However, SPF is only part of the equation. The type of sunscreen matters. Mineral sunscreens, containing zinc oxide or titanium dioxide, are generally considered safer and more effective, especially for sensitive skin. They work by creating a physical barrier that reflects UV rays, unlike chemical sunscreens that absorb them.
Apply sunscreen liberally, about an ounce (a shot glass full) for your entire body, and reapply every two hours, or more frequently if swimming or sweating. Don’t forget often-missed areas like the ears, back of the neck, and tops of the feet.
Consider specific brands known for their efficacy and skin-friendly formulations. EltaMD UV Clear Broad-Spectrum SPF 46 is a popular choice among dermatologists, known for its lightweight feel and suitability for acne-prone skin. Blue Lizard Australian Sunscreen is another excellent option, particularly for those with sensitive skin, as it’s free of parabens and fragrances.
Clothing is your next line of defense. While any clothing offers some protection, darker colors and tightly woven fabrics provide more effective shielding.
Consider investing in sun-protective clothing with an Ultraviolet Protection Factor (UPF) rating. UPF indicates how much UV radiation can penetrate the fabric. A UPF of 50 means that only 1/50th (2%) of the sun’s UV radiation can penetrate the fabric.
Companies like Coolibar and Patagonia offer a wide range of stylish and functional UPF clothing, from long-sleeved shirts and pants to hats and swimwear. A wide-brimmed hat is crucial for protecting your face, neck, and ears. Sunglasses are also essential to protect your eyes from UV damage, which can lead to cataracts and macular degeneration.
Timing your outdoor activities can significantly reduce your UV exposure. The sun’s rays are strongest between 10 a.m. and 4 p.m. During these peak hours, seek shade whenever possible.
Plan your walks in Savannah’s Historic District for early morning or late afternoon, when the sun is less intense. Utilize the shade provided by buildings, trees, and awnings.
Even on cloudy days, UV radiation can penetrate the clouds, so sun protection is still necessary.
One common mistake is relying solely on sunscreen. Sunscreen is effective, but it’s not a suit of armor. It should be used in conjunction with other protective measures like clothing, hats, and shade.
Another pitfall is not reapplying sunscreen frequently enough. Sunscreen wears off over time, especially when sweating or swimming. Set a timer on your phone to remind you to reapply every two hours.
Many people also underestimate the reflective power of sidewalks and other surfaces. Remember that UV radiation can bounce off concrete, sand, water, and even snow, increasing your overall exposure.
Consider the specific challenges of Savannah’s environment. The humidity can make sunscreen feel sticky and uncomfortable, leading people to skip application. Opt for lightweight, non-greasy formulas that are designed for humid climates.
The historic cobblestone streets, while charming, can make walking more strenuous, leading to increased sweating and the need for more frequent sunscreen reapplication.
For those who enjoy walking tours of Savannah, plan your tours for early morning or late afternoon, and choose routes that offer ample shade. Carry a lightweight, foldable umbrella for extra sun protection.
Consider the impact on children. Children’s skin is more sensitive to UV radiation than adult skin. Protect children with sunscreen, hats, and clothing, and limit their exposure during peak hours.
Educate yourself and others about the risks of UV exposure and the importance of sun protection. Share this information with your friends, family, and community.
By taking these precautions, you can enjoy the beauty and charm of Savannah without compromising your skin health. Don’t let the sun’s hidden dangers ruin your visit or your long-term well-being. Be proactive, be informed, and protect your skin.
