Not all clothing protects you from the sun equally. Fabric type, weave density, and color all affect how much UV radiation reaches your skin.
This guide covers how UPF ratings work, which fabrics block the most rays, and how to protect yourself from solar radiation effectively.
Why Are Ultraviolet Rays Harmful?
Forty years ago, the search for materials that can adequately block UV rays began in Australia. Sun protection matters because there are two types of harmful UV rays.
UVA rays have a longer reach and age skin faster. UVB rays have a shorter reach but can still cause serious damage.
Although these rays bounce off the skin, they can cause cancer. There are three main kinds of skin cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma.
They’re primarily caused by exposure to harmful UV rays.
If skin is left unprotected, UV rays can damage the DNA in skin cells. In 1998, the AATCC accepted the Australian ultraviolet protection factor standard in the US.
After that, the American Society for Testing and Materials (ASTM) started developing standards for sun protection clothing. Sun protective clothing provides better protection and affordability than sunscreen alone.
What Are the Advantages of Sun Protective Clothing?
When considering the harmful effects of sun rays, sun protective clothing is a must for anyone who spends time outdoors directly exposed to the sun.
One sun-protective shirt lasts many seasons. It also maintains its UPF rating after being washed hundreds of times.
Dermatologists highly recommend sun-protective clothing because it offers consistent, reliable protection. The degree of sun protection stays constant throughout the day.
Health care providers also recommend that if you use sunscreen, it should be water-resistant with at least SPF 50. Apply it on exposed skin every 2 hours.
How to Buy UV Protective Clothing
Clothing in general will shield you from the sun. But not all materials and colors give you equal protection.
Tightly woven fabrics are more successful at blocking UV rays than thin fabrics. Keep the following factors in mind when shopping for protective clothing.
Color
Radiant colors keep UV rays from reaching your skin by absorbing the sun’s rays. These colors also prevent UV rays from penetrating the clothing.
Construction
Heavily woven cloth like denim, canvas, wool, and synthetic fibers give more protection than lightly woven cloth. One way to check a fabric’s sun protection is by holding it up against the sun.
If you can see through the material, UV radiation can pass through easily and reach your skin.
Which Materials Give the Best Sun Protection?
Unbleached cotton is a natural UV absorber and has one of the best sun protection factors. Polyester and lightweight satiny silks offer high sun protection because of their radiation reflection.
Fabrics treated with chemical UV absorbers can also stop some UV rays from penetrating. These high-tech fabrics are a good option for sun protection gloves and other accessories.
Fit
Loose-fitting clothes are more desirable because tight clothes stretch and allow UV radiation through the fibers. When fibers pull away from one another on a person’s body, they let more UV rays pass through and don’t provide good sun protection.
Ultraviolet Protection Ratings
Some apparel makers add ultraviolet sun protection labels. These labels tell you exactly how much the clothing shields you from UV rays.
Coverage
If your clothing covers more skin, you logically have more protection from the sun. Long-sleeved garments, pants, and long skirts give more sun protection.
A sun protection hoodie covers your arms, neck, and head in a single garment, which simplifies your routine on long outdoor days.
How to Shield Yourself from UV Radiation
The strength of the sun’s rays matters. The amount of UV exposure depends on the time you spend under the sun, how long your skin is exposed, and whether you’re wearing proper apparel or sunscreen.
If you live in an area with heavy sunlight, you’re at higher risk of developing skin cancer.
One of the easiest ways to protect yourself from sun rays is by wearing a hat. A hat with at least a 2-3 inch brim is ideal.
A shade cap with 7 inches of fabric also works well and gives the neck added protection.
Baseball caps only protect the front and top of the head. They don’t protect the neck or ears, where cancers are most likely to appear.
How to Protect Yourself at the Beach
There are several things to keep in mind when spending time at the beach.
Stay in the Shade
Staying in the shade greatly reduces sun exposure. It’s the simplest step you can take.
Wear Sun Protective Clothing
Not all clothing provides enough protection against ultraviolet light. Most fabrics won’t give you sufficient UV protection on their own.
Protect your skin using tightly woven fabrics and quality sunscreen for outdoor activities. During hot summer days, the clothing you wear has a major impact on your level of UV protection.
Finding apparel with good UPF ratings is key. Here are the specific ratings to look for:
- 15, 20: Good Protection
- 25, 30, 35: Very Good Protection
- 40, 45, 50, 50+: Excellent Protection
The UV transmission percentages break down like this:
- 6.7 to 4.2%: Good Protection
- 4.1 to 2.6%: Very Good Protection
- Less than 2.5%: Excellent Protection
Wear Sunglasses
Sunglasses protect your eyes and reduce cataract risk. They also protect the tender skin around the eyes from wrinkles.
Sunglasses that block both UVA and UVB rays give you the best protection. Wrap-around sunglasses work especially well because they block UV rays from reaching the sides.
UV Protection Levels of Different Clothing
To have the best sun protection, you need a combination of different factors. Wearing clothing with UV protection is a must.
While clothing with a high UPF rating gives good shielding, it won’t be enough on its own. How much protection clothing provides depends on fabric quality and shade of the clothes.
Avoid loosely woven fabrics since tight weaves protect much better from skin damage. Lighter shades block more UV light compared to darker shades that absorb the sun’s rays.
Make sure to wear long sleeves and cover exposed areas with broad-spectrum sunscreen. Wear wide-brim hats and sunglasses that offer 100% UV protection for the best cataracts prevention.
A high SPF prevents sun damage and lowers your cancer risk.
Solar Energy and Solar Powered Clothing
Solar panels are made from silicon wafers or other materials that collect the sun’s rays for energy. They can also be placed in clothing.
Now you can charge your phone and tablets through small panels embedded in your clothing. The possibilities are truly impressive.
Charging devices with a USB port integrated into fabric will be convenient for wearers. If these materials are implemented on a larger scale, there’ll be a huge cutback in electrical power usage.
In 2017, the University of Tokyo and research institute RIKEN demonstrated a prototype called ultra-thin photovoltaic material. It’s a stretchable, waterproof material.
Clothing with embedded solar cells just 3mm by 1.5mm creates these solar-powered clothes.
Solar Fabric for Tents
Solar-powered tents are a potential solution for people who’ve lost their homes from natural disasters like flooding or earthquakes. They provide shelter and electrical power without needing separate power generators.
Sun-powered electrical power is renewable. Solar-powered tents can bring relief faster and more reliably than many alternatives.
Solar-Powered Hats
Solar-powered hats are fun to wear. Some have cooling fans that turn on when you go outside and turn off when you go indoors.
Some hats include a compass and a USB port for charging your phone.
Frequently Asked Questions
What UPF rating should I look for in sun protective clothing?
Look for clothing with a UPF rating of at least 30 for very good protection. A UPF 50+ rating blocks over 98% of UV rays and offers excellent coverage.
The rating stays consistent through washing and wear, unlike sunscreen that needs reapplication every two hours throughout the day.
Does wet clothing provide less UV protection?
Yes, wet clothing typically offers less UV protection than dry clothing. Water causes fabric fibers to stretch and become more transparent to UV rays.
A dry cotton shirt with a UPF of 30 might drop to a UPF of 10 or less when soaked. Consider wearing quick-dry fabrics with built-in UPF ratings for water activities.
Can regular clothing replace sunscreen entirely?
Regular clothing helps but can’t replace sunscreen completely. Exposed areas like your face, hands, and neck still need sunscreen coverage.
Even clothing with high UPF ratings leaves gaps at the neckline, wrists, and ankles. The best approach combines sun protective clothing with broad-spectrum SPF 50 sunscreen on all uncovered skin.
How does clothing compare to sunscreen for sun protection?
Clothing generally provides more consistent protection than sunscreen because it doesn’t wear off, wash away, or require reapplication. A shirt with UPF 50 blocks 98% of UV rays all day long.
Sunscreen degrades with sweat, water, and time. For maximum coverage, use both together on sunny days outdoors.
Final Thoughts
Sun protective clothing is one of the most reliable ways to shield your skin from harmful UV rays. The right fabric, fit, and UPF rating make a big difference.
Pair protective clothing with sunscreen on exposed skin, a wide-brim hat, and quality sunglasses for complete coverage. New developments in solar-powered fabrics may soon add energy generation to the list of benefits your clothes provide.
