Can You Get Sunburned Through A Shirt?

Did you know that even on a cloudy day, you can still get sunburned through a shirt? While it may seem counterintuitive, the truth is that certain fabrics and clothing materials provide little to no protection against the harmful effects of UV rays. So, the next time you head out in the sun, it's important to consider whether your clothing will truly shield you from sunburn.

When it comes to sunburn, not all clothing is created equal. Some fabrics, like tightly woven fabrics or those treated with a UV-protective coating, can provide a higher level of sun protection. However, other materials, such as thin or loosely woven fabrics, may allow UV rays to penetrate through, increasing the risk of sunburn. Additionally, the color of your clothing can also make a difference. Darker colors tend to absorb more UV radiation, while lighter colors reflect it. So, while wearing a shirt may provide some level of protection, it's crucial to choose the right fabric and color to effectively minimize the risk of sunburn.

The Effectiveness of Shirts in Protecting Against Sunburn

When it comes to protecting our skin from the harmful effects of the sun, one of the first things we rely on is clothing. Wearing a shirt can provide a physical barrier between our skin and the sun's rays, but can it truly prevent sunburn? In this article, we will explore the effectiveness of shirts in protecting against sunburn and the factors that can influence their efficacy.

The Role of Fabric in Sun Protection

The type of fabric used in a shirt plays a crucial role in determining its effectiveness in preventing sunburn. Not all fabrics provide the same level of sun protection, as some may be more tightly woven or have special coatings designed to block harmful UV radiation.

Ideally, a shirt that provides adequate sun protection should have a tight weave or a high UPF (Ultraviolet Protection Factor) rating. UPF measures the amount of UV radiation that can penetrate the fabric and reach the skin. A higher UPF rating indicates better protection against the sun's harmful rays.

Certain fabrics, such as polyester, nylon, and tightly woven fabrics like denim or canvas, offer better sun protection compared to sheer or lightweight fabrics like silk or linen. It is important to note that even though these fabrics provide some level of sun protection, they are not foolproof and should be used in conjunction with other sun protection measures.

Choosing the Right Fabric

When selecting a shirt for sun protection, it is essential to consider the fabric type and its UPF rating. Look for shirts specifically advertised as "sun protective" or "UPF-rated" to ensure that they have undergone testing to verify their sun protection claims.

Additionally, choose shirts with a tighter weave and darker colors, as they tend to offer better protection against UV rays. Darker colors absorb more light, reducing the amount that reaches the skin. Avoid shirts with thin or sheer fabrics, as they allow more UV radiation to penetrate and increase the risk of sunburn.

Remember to consider factors such as fit and coverage. Shirts with long sleeves, collars, and longer hems provide better coverage and protection for areas prone to sunburn, such as the neck, shoulders, and arms. Comfort is also important, as shirts that are too tight or uncomfortable may discourage regular use and compromise sun protection.

The Effect of Wet Shirts on Sun Protection

While a dry shirt can provide some level of sun protection, it is crucial to note that the effectiveness can be significantly reduced when the shirt becomes wet. Wet fabric stretches and becomes more transparent, allowing more UV radiation to reach the skin.

Swimming or engaging in water activities with a regular shirt can diminish its sun protection capabilities. Instead, opt for shirts specifically designed for water activities, which are made of special fabrics that maintain their sun protection properties even when wet.

It is also important to reapply sunscreen regularly, even if wearing a sun-protective shirt. Sunscreen provides an additional layer of protection and can compensate for any potential gaps in coverage or decreased effectiveness due to wet shirts.

Other Factors Affecting Sunburn Through Shirts

While the fabric and type of shirt are vital in sun protection, there are other factors that can influence the risk of sunburn even when wearing a shirt.

Time of Day and Intensity of the Sun

The time of day and the sun's intensity play a significant role in the risk of sunburn, even when wearing a shirt. The sun's rays are strongest between 10 am and 4 pm, so it is advisable to seek shade or use additional sun protection measures during these hours, regardless of the type of shirt you are wearing.

Additionally, geographical location and altitude can affect the sun's intensity. UV radiation tends to be stronger at higher altitudes and near the equator. It is crucial to consider these factors when evaluating the effectiveness of a shirt in preventing sunburn.

Remember that UV radiation can penetrate clouds, so even on cloudy days, it is essential to protect your skin and use sun-protective clothing, including shirts.

Clothing Fit and Coverage

The fit and coverage of the shirt can also impact its effectiveness in preventing sunburn. Loose or oversized shirts may expose more skin to UV radiation, increasing the risk of sunburn. Additionally, areas where the shirt does not provide coverage, such as gaps around the neckline or rolled-up sleeves, are vulnerable to sunburn.

Wearing long-sleeved shirts, hats, and sunglasses along with sunscreen, seeking shade, and staying hydrated are all important aspects of comprehensive sun protection, even when relying on shirts for shielding the skin from the sun.

The Bottom Line

While shirts can offer some level of protection against sunburn, it is important to choose the right fabric, fit, and coverage to maximize their effectiveness. Look for shirts with a tight weave, high UPF rating, and darker colors for better sun protection. Remember that wet shirts can compromise their sun protection capabilities, so choose specialized water-resistant shirts for water activities. Additionally, consider other factors like the time of day, sun intensity, and geographical location when evaluating the risk of sunburn. Lastly, always complement sun-protective clothing with sunscreen, seeking shade, and practicing other sun safety measures for comprehensive protection against harmful UV radiation.

Can Clothing Protect Against Sunburn?

Wearing a shirt provides some protection against the harmful effects of the sun's ultraviolet (UV) rays. However, it does not offer complete protection. The level of protection depends on various factors such as the fabric type, color, thickness, and weave.

Certain fabrics like tightly woven polyester and nylon offer better protection than loosely woven fabrics like cotton or linen. Dark or bright-colored clothing can also provide more UV protection compared to light-colored clothing. Additionally, clothes with a higher UPF (Ultraviolet Protection Factor) rating offer better protection against the sun's rays.

It is important to note that the sun can still penetrate through clothing, especially if it is wet or stretched tightly against the skin. Unprotected areas like the neck, hands, and face are particularly susceptible to sunburn. Therefore, it is recommended to use additional sun protection measures such as applying sunscreen, wearing a hat, and seeking shade during peak sun hours.


Key Takeaways:

  • Wearing a shirt provides some protection against sunburn, but not complete protection.
  • The type of fabric and its tightness weave determines the level of sun protection.
  • Light-colored shirts and synthetic fabrics offer less sun protection compared to dark-colored shirts and natural fibers.
  • UPF (Ultraviolet Protection Factor) clothing provides enhanced protection against harmful UV rays.
  • It is still important to apply sunscreen on exposed skin even when wearing a shirt.

Frequently Asked Questions

Here are some common questions and answers about sunburns through a shirt:

1. Can you get sunburned through a shirt?

Yes, you can still get sunburned through a shirt. While clothing can provide some level of protection against the sun's harmful UV rays, it is not enough to fully shield your skin. Most regular clothing has a UPF (ultraviolet protection factor) of around 5-10, which means it only blocks about 10% of the UV rays.

To ensure maximum sun protection, it's recommended to wear clothing with a higher UPF, specifically designed for sun protection. Look for clothing labeled with a UPF rating of 30 or higher, as they provide greater protection against sunburns.

2. What types of fabric are best for sun protection?

Certain types of fabrics offer better protection against the sun than others. Look for clothing made from tightly woven fabrics such as nylon, polyester, or silk, as they allow less UV radiation to pass through them. Lighter-colored fabrics also tend to reflect more sunlight and offer better protection.

Avoid wearing clothing made from loosely-woven fabrics, such as linen or loosely-knit cotton, as they allow more UV radiation to pass through and increase the risk of sunburn.

3. Can a thin shirt protect against sunburn?

A thin shirt may provide some level of protection against the sun, but it is not sufficient on its own. Thin fabrics, especially if they are light-colored or loosely-woven, may still allow a significant amount of UV radiation to reach your skin, increasing the risk of sunburn.

If you are planning to spend an extended period of time in the sun, it's better to opt for clothing with a higher UPF rating and made from tightly woven fabrics.

4. Does sun-protective clothing need reapplying like sunscreen?

No, sun-protective clothing does not need to be reapplied like sunscreen. Unlike sunscreen, which wears off over time and needs to be reapplied every few hours, sun-protective clothing offers continuous protection as long as you are wearing it properly.

However, it's important to note that sun-protective clothing can lose its effectiveness over time, especially with repeated washing and exposure to UV radiation. It's recommended to regularly inspect your sun-protective clothing for any signs of wear or damage and replace them as needed to ensure continued protection.

5. Can you still get a tan through a shirt?

While wearing a shirt can provide some level of protection against sunburn, it does not prevent your skin from tanning. UV rays can still penetrate through the fabric and stimulate melanin production in your skin, resulting in a tan.

If you want to minimize tanning while wearing a shirt, it's advisable to choose clothing with a higher UPF rating and tighter weave to block more UV radiation.



So, can you get sunburned through a shirt? The answer is yes, but it depends on the type of shirt and its thickness. While a regular t-shirt may provide some protection, it is not enough to completely shield your skin from harmful UV rays. A thin, light-colored shirt can typically let about 20% of the UV rays pass through, which can still lead to sunburn.

If you want to protect your skin from the sun, it is essential to wear clothing specifically designed for sun protection. Look for garments with a UPF (Ultraviolet Protection Factor) rating, which indicates how effectively the fabric blocks UV rays. UPF clothing, like rash guards or sun shirts, can offer excellent protection by blocking most of the UV radiation, reducing the risk of sunburn and skin damage.
