Is 11 UV index safe
A UV Index reading of 11 or more means extreme risk of harm from unprotected sun exposure. Take all precautions because unprotected skin and eyes can burn in minutes. Try to avoid sun exposure between 10 a.m. and 4 p.m.
What happens if UV index is 11
The UV index is reported as a whole number between 0 and 11(+), with 0 indicating absolutely no sunlight (used only at night!) and 11 indicating extreme radiation, when you can burn in less than 10 minutes.
What UV number is safe

How long to stay in UV 11
A UV Index reading 11 or higher puts you in a very dangerous spot for sunburn with damage occurring in less than 10 minutes if unprotected. At this level it is best to avoid all sun exposure between 10AM and 4PM. Find out the UV Index Level near you and protect yourself from damaging skin exposure.
Can UV go above 10
The UV Index was previously reported on a scale of 0 to 10+, with 0 representing “Minimal” and 10+ representing “Very High.” As of May 2004, EPA and NWS will report the Global Solar UV Index using a scale of 1 (or “Low”) to 11 and higher (or “Extreme”).
Is UV Index 10 safe
A UV Index of 8-10 (Very High) means there is high risk of harm from unprotected sun exposure. Fair skinned people may burn in less than 10 minutes. Minimize as much sun exposure as possible during the midday hours of 10 a.m. to 2 p.m. Liberally apply a broad spectrum sunscreen of 30+ SPF.
How long does it take to tan in UV 11
TABLE 1. MINUTES OF SUNLIGHT EXPOSURE FOR SUFFICIENT VITAMIN D
| SKIN REACTION TO SUNLIGHT | UV Index | |
|---|---|---|
| 3-5 | 11+ | |
| Skin type III: Occasionally burn, slowly tan | 20-30 min. | 5-10 min. |
| Skin type IV: Rarely burn, rapidly tan | 30-40 min. | 10-15 min. |
| Skin type V & VI: Very rarely burn, always dark | 40-60 min. | 15-20 min. |
Can you tan in the shade UV 11
Yes, you can still get a tan while sitting in the shade, although it may be less intense and take longer to develop than if you were in direct sunlight. This is because UV rays can still penetrate through clouds and reflect off surfaces, such as water, sand, or snow.

Can the UV be 12
The UV Index Scale
UV Index 3-5 means low risk of harm from unprotected sun exposure. UV Index 6-7 means moderate risk of harm from unprotected sun exposure. UV Index 8-10 means high risk of harm from unprotected sun exposure. UV Index of 11+ means a very high risk of harm from unprotected sun exposure.
How long can you be in 11 UV
A UV Index reading 11 or higher puts you in a very dangerous spot for sunburn with damage occurring in less than 10 minutes if unprotected. At this level it is best to avoid all sun exposure between 10AM and 4PM. Find out the UV Index Level near you and protect yourself from damaging skin exposure.

A UV Index reading 11 or higher puts you in a very dangerous spot for sunburn with damage occurring in less than 10 minutes if unprotected. At this level it is best to avoid all sun exposure between 10AM and 4PM. Find out the UV Index Level near you and protect yourself from damaging skin exposure.
How high is 11 UV
Moderate: A moderate UV index is 3 to 5. High: A high UV index is 6 or 7. Very High: If the UV index is 8 to 10, it's considered very high. Extreme: Finally, extreme UV radiation is 11+
How long does it take to burn in 11 UV
UV rating 11+ — Any rating of 11 or higher is considered to be extreme levels of UV radiation exposure. Capable of causing a severe sunburn in under 10 minutes, it is advised that you take all precautions possible to limit your exposure to the sun at this UV rating.
Is 11 the highest UV
Other classifications are moderate (3-5), high (6-7), very high (8-10) and extreme (11+). To some extent, the moderate to very high labels tell us little except that UV intensity is increasing. The most simple advice is that when the index is at 3 or higher, protect your skin.

Is 11 the highest UV index
The higher the UV Index, the greater the strength of the sun's UV rays and the faster you may burn. The index predicts the risk of UV overexposure on a scale of 0 (minimal risk) to 11+ (very high risk).
Is SPF 15 ok
An SPF of at least 15 is recommended. Products with SPF 30 provide high protection against sunburn. The FDA states that products with SPF above 30 provide a benefit that is not much greater than SPF 30 products. Water-resistant products provide protection for up to 40 minutes of water activity or sweating.
Is 10 SPF enough
Notice that once you hit an SPF of 10 a sunscreen blocks 90% the percent of UVB rays. After that, the percent of UVB blocked doesn't go up very much as the SPF numbers go up. The sweet spot is SPF 30 where 97% of the UVB rays are blocked, and most dermatologists agree.
Is SPF 18 enough for face
While wearing sunscreen is better than not wearing any, if you have a choice, it's best to choose a sunscreen with broad-spectrum UV protection of at least SPF 30. These recommendations apply to people of all skin tones.
What is the lowest safe SPF
SPF 30
Here's what the major health authorities say:
The American Academy of Dermatology recommends using sunscreen with SPF 30 or higher.
Is SPF 15 too little
For starters, SPF 15 will block roughly 93% of UV rays when applied thoroughly. That's a huge benefit, but a simple upgrade to SPF 30 will shield 97% of rays. It only increases slightly from there. SPF 50 blocks 98%, and SPF 100 blocks 99%.
Is SPF 15 too low
Here's what the major health authorities say:
The American Academy of Dermatology recommends using sunscreen with SPF 30 or higher. The Skin Cancer Foundation recommends SPF 15 every day you leave your house and SPF 30 if you plan to be in the sun most of the day.
