Are you tired of getting your tan from a bottle? It’s possible to get a healthy tan and summer glow without causing skin damage. The key is to understand the UV index for tanning and limit your sun exposure accordingly. The UV index measures the strength of the UV radiation from the sun’s rays, showing when it’s safe to work on your sun tan and when to stick to short exposures to prevent damage.

Skin protection is something you should care about at every age, but especially if you’re concerned about premature aging. As a dermatology clinic, almost all of our clients ask us about sun protection and the best ways to develop a natural tan.

Key Takeaways – Best UV for Tanning

Using the UV index for tanning can help plan your sun exposure to safely get a tan without causing long-term skin damage.
Always apply a daily sunscreen, even on cloudy and overcast days, and limit your maximum time in the sun by regularly seeking shade. It’s best practice to wear a wide brimmed hat, sunglasses, and lip balms with an SPF to protect sensitive areas from the sun.
The World Health Organization recommends that the safe UV index for tanning is 3 to 5 to limit UV radiation.

What is the UV Index?

The UV index scale was developed by Canadian scientists to better inform the public about sun protection. It measures the UV exposure that reaches the Earth’s surface. The UVI values range from 0, meaning minimal risk, to 11+, which represents extreme ultraviolet radiation. The higher the UV index, the more dangerous the UVA and UVB rays will be.

Understanding the UV Index

The UV index considers three types of UV radiation: UVA, UVB, and UVC.

UVA rays generate deep into the skin, resulting in a darker skin colour and can cause skin aging. UVB radiation cause sunburn and are associated with skin cancer. UVC rays are usually absorbed by the atmosphere and do not reach Earth’s surface.

UV index of 3-5 will allow you to tan safely as the sun stimulates melanin production without causing sun damage to your skin. You can still develop sunburn if you’re not wearing sunscreen.
UV index of 6-7 is considered high. While you can tan, you’ll be more likely to damage your skin.
UV index of 8-10 is very high due to the level of uv radiation with long-term exposure increasing your risk of skin cancer.
UV index of 11+ is extreme and not appropriate for tanning. You’ll want to continuously reapply sunscreen and avoid extensive sun exposure.

The Danger of UV Rays and Skin Cancer

Tanning can go wrong, especially if you fall asleep in direct sunlight or remain in the sun during peak hours. Extended UV radiation can damage DNA in your skin cells, causing cancer. Almost 90% of melanoma cancer cases in the UK could be prevented if patients took active steps to avoid long-term UV radiation and sunbeams. Sunscreen is your best friend for protecting your skin.

Safe Tanning – How to Get a Summer Glow Without Burning!

If you’re someone who burns easily, you’ll want to take extra precautions – even if it’s not a sunny day. Whether you’re jetting to the southern hemisphere or want to take skin protection seriously, there are steps you can take to achieve a healthy tan without burning. We’re sharing our tips and tricks of how to tan and not burn.

Tips and Tricks for Tanning Safely with the UV Index

Apply a broad spectrum sunscreen with at least 30 SPF. Reapply immediately after swimming or sweating, otherwise do so every two hours. Check the daily UV index.
Wear protective clothing to reduce your exposure to ultraviolet rays, especially for sensitive areas. Bring along a wide-brimmed hat, protective sunglasses, and your favourite lip balms.
Keep your skin and body hydrated by drinking water and limiting alcohol intake.
Stick to short exposure times to protect your skin, especially when the UV index forecast is at its highest.
Take regular breaks from the sun and follow the shadow rule. If your shadow is short, you should seek shade. If your shadow is longer, the UV rays are less intense.

Frequently Asked Questions

What is a good UV for tanning?

The best UV index for tanning is 3-5 as it's strong enough to stimulate melanin levels without heightened risk of premature aging or sunburn.

When is the best time of day to tan?

You can usually tan safely in the morning or later afternoon when the sun is at a good UV index. You can use your smartphone's weather app to identify when the sun is going to be at its brightest to avoid burning and to know when to seek shade. The UV index is typically at its highest between 10am to 4pm, when we recommend wearing protective clothing and limiting your exposure.

Can I tan on a cloudy day?

There's no such thing as a day without the sun's UV rays. Up to 80% of UV light can penetrate through cloud cover, meaning you can still get a tan - or sunburn - even on a cloudy day. That's why managing your UVA radiation is crucial. Our top advice for all skin types is to wear a daily sunscreen.

How often should I reapply sunscreen throughout the day?

It's a common misconception that sunscreen lasts for long periods. Regardless of your skin type, you should apply sunscreen at least every two hours to ensure continuous protection. Ask a friend or family member to help with those hard to reach spots, like your back and shoulders. Always reapply sunscreen immediately after working out, swimming, or using a towel.

What type of SPF should I use when tanning?

We recommend that you wear sunscreen with an SPF of at least 30 to protect against UV radiation.

What should I do if I get sunburnt?

If your skin is showing signs of sun damage, it's important to seek shade and apply a moisturiser or aloe vera lotion to soothe irritation. Limit your sun exposure to reduce the harmful effects that can develop more rapidly when your skin is burnt. If your skin is inflamed or painful, use a pain relief tablet and reapply hydrating skincare products regularly.
