03 Jul Choosing the Right Sunscreen for Houston Residents
As we observe National UV Protection Month, it’s essential to focus on how to protect ourselves from the sun’s harmful rays, especially in sunny regions like Houston, Texas. With the city’s hot and humid climate, choosing the right sunscreen is crucial for effective protection.
Dr. Quinn offers the following guide to help you select the best sunscreen for your needs.
Understanding UV Radiation
The sun emits two types of harmful ultraviolet (UV) radiation that reach the Earth’s surface: UVA and UVB rays. UVA rays can prematurely age your skin, causing wrinkles and age spots, while UVB rays can burn your skin. Both types contribute to the risk of skin cancer. Effective sunscreens offer protection against both types of rays.
Key Factors to Consider:
SPF Rating: SPF stands for Sun Protection Factor. It measures how well the sunscreen protects against UVB rays. Dermatologists recommend using a sunscreen with at least SPF 30, which blocks about 97% of UVB rays. Higher SPF numbers offer slightly more protection but no sunscreen can block 100% of UVB rays. For Houston’s intense sun, an SPF 50 can provide additional peace of mind.
Broad-Spectrum Protection: Ensure the sunscreen is labeled “broad-spectrum,” meaning it protects against both UVA and UVB rays. This comprehensive protection is crucial for preventing both sunburn and long-term skin damage.
Water Resistance: Houston’s humidity and tendency for outdoor activities make water-resistant sunscreen a smart choice. Water-resistant sunscreens are effective for up to 40 or 80 minutes of swimming or sweating. Remember to reapply after swimming, sweating, or towel drying.
Type of Sunscreen: Sunscreens come in various forms, including lotions, sprays, gels, and sticks. Lotions are great for dry skin and ensure even coverage. Sprays are convenient for reapplication, especially for hard-to-reach areas, but be sure to spray generously and rub it in. Sticks are excellent for the face, especially around the eyes.
Ingredients: For sensitive skin, look for sunscreens containing physical (mineral) blockers like zinc oxide or titanium dioxide. These are less likely to cause irritation. Chemical sunscreens, which include ingredients like oxybenzone or avobenzone, absorb UV radiation and dissipate it as heat but can sometimes cause skin reactions.
Sunscreen Application Tips
Apply Generously: Most people apply too little sunscreen. You need about one ounce (a shot glass full) to cover your entire body. Apply it 15 minutes before going outside to allow it to absorb into the skin.
Reapply Frequently: Reapply sunscreen every two hours, or immediately after swimming, sweating, or towel drying. This is crucial to maintain effective protection.
Don’t Forget Key Areas: Remember to protect your ears, neck, the tops of your feet, and the back of your knees. Use a lip balm with SPF for your lips. Use Daily: UV radiation can damage your skin even on cloudy days or during the winter. Incorporate sunscreen into your daily skincare routine, especially on exposed areas like your face, neck, and hands.
Additional Sun Protective Measures
In addition to applying sunscreen, it’s also important to use other forms of sun protection:
- Wear protective clothing, including long-sleeved shirts, pants, and wide-brimmed hat.
- Seek shade, especially during peak sun hours between 10 a.m. and 4 p.m.
- Wear sunglasses with UV protection to safeguard your eyes.
Living in Houston means dealing with intense sun and high UV index levels. By choosing the right sunscreen and applying it correctly, you can enjoy the outdoors while protecting your skin from harmful UV radiation. Embrace National UV Protection Month by making sun safety a daily habit, ensuring your skin remains healthy and radiant for years to come.
