Can You Tan Through Clothes?
Ensure to shield exposed skin from the sun’s rays with sunscreen, yet consider the protection for unexposed skin. Do your clothes guard against sunburn?
Regrettably, not all garments provide full protection from the sun's UV rays. The level of protection varies depending on the clothing material.
If light passes through the material of your clothes when held up, it indicates UV rays can penetrate.
It's possible to sunburn through clothes. Certain types offer better protection.

What to know about UV rays?
The two primary types of UV (ultraviolet) radiation to be aware of are UVA and UVB.
UVA makes up the bulk of the radiation reaching our planet (95%Trusted Source). It leads to skin cancer and accelerates skin aging.
UVB causes reddening and burning of the skin. While it represents only 5% of incoming radiation, it is the primary cause of most skin cancers.
A helpful mnemonic for identifying each type is: “A” for aging and “B” for burning.
It is crucial to shield yourself from both UVA and UVB rays as they can both lead to skin cancer.
UV rays can still be present even when it's not warm outside. The warmth from the sun comes from infrared rays, not UV. Therefore, UV rays are not always strongest when it's hottest.
When is the UV strongest?
| UV Index (UVI) | UV intensity |
| 0 to 2 | Low |
| 3 to 5 | Moderate |
| 6 to 7 | High |
| 8 to 10 | Very high |
| 11 | Extremely high |
Review the local weather forecast to determine the UV index.
The higher the UV index, the more likely you are to get a sunburn.Trusted Source When the UV index is higher, you’ll need more protection, as you may burn faster.
Can UV go through clothes?
Have you ever questioned the level of sun protection your clothing offers and how effectively it shields your skin from UV rays?
UV rays can pass through clothing to reach the skin. A white cotton t-shirt may have a UPF rating of 5, allowing about 20% of UV radiation to penetrate the fabric and skin.
What does this mean?
Given the cumulative nature of sun exposure, even minor instances of intermittent sun exposure can accumulate and raise the risk of skin damage and skin cancer. This is where Ultraviolet Protection Factor (UPF) clothing becomes essential.
The UPF rating of a garment measures the amount of the sun’s broad spectrum ultraviolet radiation blocked by the fabric before reaching your skin. UPF50+ is the top rating on the UPF scale, indicating that 98% of the sun's UVA and UVB rays are blocked from reaching your skin. Lacking a UPF rating makes it difficult to determine the level of sun protection provided by a piece of clothing.
Numerous factors dictate the sun protection level provided by clothing. Fabric type, weave density, thickness and weight, color stretch, moisture content, and fabric condition all influence the UPF rating.
For instance, a denim jacket may have a high UPF rating and function as a dependable barrier against the sun and your skin, yet due to its weight and fabric composition, it may not be the most comfortable attire on a hot, sunny day.
Specialist UPF50+ sun protective clothing is designed to keep your skin shielded from the sun. It offers excellent UV ray protection, while remaining lightweight and durable for optimal comfort outdoors.
Australia's government tests and certifies sun protective fabrics, making Australian UPF clothing a top choice for reliable protection. Australia has a well-documented history of leading advanced sun protection due to the high incidence of skin cancer diagnoses in the Australian population. The goal at Qikini is to establish a skin cancer-free world through the distribution of Australian certified UPF50+ sun protection globally.

Can you sun tan or sunburn through your clothes?
Indeed, one can acquire a sun tan and sunburn through clothing.
UV light passing through clothing can result in tanning or burning even when covered up.
However, certain apparel choices provide improved protection.
Ensure garments remain dry as wet clothing provides reduced UV protection compared to dry clothing.
Frequently Asked Questions (FAQs)
What's the difference between UPF and SPF?
UPF measures how much UV light a fabric allows to pass. SPF measures how long sunscreen shields your skin from UV rays.
UPF applies to clothing, whereas SPF applies to sunscreen.
Does tight-fitting clothing protect better than loose clothing?
Loose clothing helps maintain the weave, enhancing UV blocking. Stretched fabric opens gaps, diminishing protection.
Do I still need sunscreen if I wear UPF clothing?
Apply sunscreen to exposed skin; UPF clothing protects only what it covers.
Takeaway
Yes, it is possible to get a sunburn through clothes. Some with tightly woven fabrics, dark colors, and UPF offer more protection.
UVA and UVB are linked to skin cancer, so protection against both is essential.
For maximum protection, be cautious when UV intensity peaks from 11 a.m. to 3 p.m., regardless of temperature. Consult your local weather forecast for UV levels
