Sun care - How to Protect Your Skin and Stay Safe Outdoors

 No matter what colour your skin, it's vital that you protect yourself in the sun. Even on a cool day or when there are clouds in the sky, the sun can still be strong enough to cause lasting damage.

 

Exposure to the sun

Some sunlight is important because our skin uses it to produce vitamin D, which helps to build and maintain strong bones. Too much sun is harmful and can damage your skin. The sun gives out ultraviolet (UV) radiation that is made up of three types of rays: UVA, UVB and UVC. UVC rays from the sun cannot get through the ozone layer. But UVA and UVB rays can, and have been linked to skin damage.

 
Short-term damage

Sun tan - A tan is a sign that your skin has been damaged and is trying to protect itself. UV radiation stimulates your skin to produce more pigment (colour) giving you a characteristic tan. Your tan will fade over time, but the skin damage remains.

 
Sunburn

Short-term overexposure to the sun can cause your skin to burn, usually making it red, hot and painful. Burnt skin can be soothed with aftersun lotions. After a couple of days, the burnt skin may peel. Severe sunburn with blistering may need medical treatment.

 
Winter sun

You cannot feel UV rays. The warmth felt on your skin on a sunny day is actually caused by the sun's infrared radiation. So, just because you can't feel the hot rays of the sun doesn't mean you won't get sunburnt.

 
The amount of UV radiation is generally lower during the winter but snow reflects most of the sun's rays, so you can still get sunburnt. Particularly if you're high up in the mountains where there is less atmosphere to block out the UV rays. Cloud doesn't stop the sun's UV rays getting through either. In fact, haze can even increase the amount of UV radiation exposure.

 

Preventing Sun Damage

 1. Limit time in the sun

Stay out of the sun between 11am and 3pm when the sun's UV rays are strongest. Look for shady areas and use umbrellas or canopies.

2. Watch the UV index

The UV index describes the strength of the sun's UV radiation. It is usually shown as a number in a triangle on a weather map. The numbers range from one to 11 and the higher the number, the stronger the UV radiation.

3. Cover up

Wear long-sleeved tops and trousers, and choose materials that have a close weave as these tend to block out the most UV rays. Be aware that wet clothing stretches and lets more UV radiation through to your skin. Wearing a wide-brimmed hat can reduce the UV radiation reaching your face by more than 50%. Sunglasses help to protect your eyes and eyelids, and wraparound sunglasses will also protect the skin around your eyes. Choose a pair of sunglasses that has the following labels: 100% UV protection and UV 400.

4. Wear sunscreen

Choose a sunscreen that has a sun protection factor (SPF) of 15 or higher. The SPF tells you how good the sunscreen is at filtering out the UVB rays. No sunscreen can offer 100 percent protection, but you will get more than 90 percent protection from UVB rays with SPF 15 and a higher percentage the higher the SPF you use. Re-apply sunscreen every two hours or more often if you've been swimming or sweating a lot. Wear complete sunblock cream on very exposed and sun-sensitive areas like your nose, ears and lips.

 
Children and the sun

Getting sunburnt as a child is known to increase the risk of developing skin cancer as an adult. Young skin is sensitive and very easily damaged by the sun's rays.

 Babies should be kept in complete shade. Cabanas (pop-up shelters) are a good way to protect children from the sun on the beach or in the garden, and parasols for prams and buggies protect children when you're out and about.

 Children should be dressed in loose-fitting clothes that cover up their arms and legs. A hat with a brim at the front and a cloth flap that covers the neck will provide good sun protection.

 
Use water-resistant sunscreen with SPF 15 or higher on all exposed areas of children's skin and apply generously every couple of hours. If you take your child swimming, re-apply the sunscreen after towel drying.
