Tucson Shade Trees: Walking Habits & Cancer Risk
By Franklin Everett ShawTucson. The Old Pueblo. A city bathed in sunshine, a place where the sun reigns supreme. But that glorious sunshine comes with a dark side: skin cancer. Arizona consistently ranks among the states with the highest rates of this disease. We can’t hide indoors forever, though. So, how do we enjoy the beauty of Tucson while minimizing our risk? The answer lies in the strategic use of our city’s natural resources: shade trees.
Walking is fantastic exercise. It’s low-impact, accessible, and a great way to explore Tucson’s unique neighborhoods. But pounding the pavement under the relentless Arizona sun is a recipe for disaster.
This isn’t about fear-mongering. It’s about making informed choices. It’s about understanding the power of shade and how to leverage it to protect yourself.
Let’s talk trees. Not all shade is created equal. A flimsy beach umbrella offers minimal protection compared to the dense canopy of a mature tree. In Tucson, we’re fortunate to have several tree species that provide excellent shade.
The Palo Verde, Arizona’s state tree, is a prime example. Its dense, green foliage offers significant UV protection. The Mesquite tree, another desert staple, is also a good choice, though its canopy can be a bit more open depending on the specific variety.
Avoid trees with sparse foliage or those that are still young and haven’t fully developed their canopy. These offer limited protection and can give a false sense of security.
So, where can you find these shady havens in Tucson? Let’s explore some of the best walking routes.
The Rillito River Park Trail is a popular choice, and for good reason. Large stretches of the trail are lined with mature Mesquite and Palo Verde trees, providing ample shade, especially during the early morning and late afternoon hours.
However, be warned: some sections of the Rillito Trail are completely exposed to the sun. Plan your walk accordingly, focusing on the shaded portions.
Another excellent option is the Santa Cruz River Park. While the river itself is often dry, the park features a well-maintained walking path with numerous shade trees. The city has invested in planting a variety of native trees, creating a more comfortable and safer walking environment.
Consider the University of Arizona campus. While not a dedicated walking trail, the campus boasts a stunning collection of mature trees, creating a network of shaded pathways. It’s a great place for a leisurely stroll, especially during the midday heat.
But simply walking under a tree isn’t enough. You need to be strategic about your timing. The sun’s intensity varies throughout the day. The hours between 10 AM and 4 PM are the most dangerous.
Plan your walks for early morning or late afternoon when the sun is lower in the sky and the shade is more effective. This simple adjustment can significantly reduce your UV exposure.
Don’t rely solely on shade. Sunscreen is still essential. Choose a broad-spectrum sunscreen with an SPF of 30 or higher and apply it liberally to all exposed skin. Reapply every two hours, or more often if you’re sweating.
Wear protective clothing. Long sleeves, pants, and a wide-brimmed hat can provide additional protection from the sun. Look for clothing with a UPF (Ultraviolet Protection Factor) rating for even greater defense.
Sunglasses are also crucial. Protect your eyes from harmful UV rays by wearing sunglasses that block 99-100% of UVA and UVB radiation.
Hydration is key. The desert heat can quickly lead to dehydration, which can exacerbate the effects of sun exposure. Drink plenty of water before, during, and after your walk.
A common mistake is assuming that shade provides complete protection. It doesn’t. UV rays can still reflect off surfaces like concrete and sand, reaching your skin even when you’re under a tree.
Another pitfall is neglecting sunscreen on cloudy days. UV rays can penetrate clouds, so it’s important to protect your skin even when the sun isn’t shining brightly.
Many people underestimate the importance of a hat. A wide-brimmed hat can shield your face, neck, and ears from the sun, areas that are often overlooked when applying sunscreen.
Let’s talk about a specific scenario: You’re planning a walk along the Rillito River Park Trail. Before you head out, check the UV index forecast for Tucson. This will give you an idea of the sun’s intensity for the day.
If the UV index is high (7 or above), consider walking during the early morning hours when the sun is less intense. Choose a section of the trail that is heavily shaded by mature trees.
Apply sunscreen liberally to all exposed skin, wear a wide-brimmed hat and sunglasses, and bring plenty of water. Take breaks in the shade as needed.
If you’re walking with children, be extra vigilant about sun protection. Children’s skin is more sensitive to the sun than adults’ skin.
Teach your children about the importance of sun safety and encourage them to wear protective clothing and sunscreen.
Remember, enjoying the beauty of Tucson doesn’t have to come at the expense of your health. By making informed choices and taking simple precautions, you can minimize your risk of skin cancer and enjoy the outdoors safely.
Consider joining a local walking group. Walking with others can provide motivation and support, and it’s a great way to discover new shaded walking routes in Tucson.
Check out the Tucson Parks and Recreation website for information on local parks and trails. Many parks offer guided walks and other outdoor activities.
Don’t let the fear of skin cancer keep you indoors. Embrace the beauty of Tucson, but do it safely. Walk under the shade of our magnificent trees, protect your skin, and enjoy the journey.
This isn’t just about extending your lifespan; it’s about enhancing your quality of life. It’s about enjoying the vibrant energy of Tucson without compromising your well-being.
So, lace up your walking shoes, find a shady path, and explore the Old Pueblo. Your skin will thank you.
