Long weekends and summer staycations: Be SunSmart whether on balconies, in back gardens or at the beach!

2020 is the year of the staycation! So while jetting away to sunnier climes is not an option right now, still spare a thought for your vulnerable skin!

Most people living in Ireland have skin type 1 or 2, which burns easily and tans poorly, so are particularly at risk from too much sun exposure. Did you know that you can get sunburnt on a cloudy day and even under the water? Or that too much sun leads to premature skin ageing, and increases skin cancer risk!

Here are a few ‘top tips’ to keep your skin in ‘tip top’ shape!

Remember A for ageing and B for burning

The sun is a source of ultraviolet (UV) radiation and there are two types we need to know about: UVA and UVB.

UVA rays penetrate more deeply through the layers of the skin than UVB. Think A for ageing – UVA is associated with skin ageing as well as skin cancer. Did you know that UVA can pass through window glass and is present year round, even on cloudy days.

Think B for burning – UVB rays are mainly responsible for sunburn but can’t pass through window glass. UVB is strongly associated with two types of skin cancer – malignant melanoma and basal cell carcinoma.

Sunscreens act like mirrors or sponges

Sunscreens help protect our skin by filtering out the sun’s UV rays. Depending on their active ingredients, sunscreen can act like a mirror, reflecting UV radiation away from the skin (e.g. when it contains filters such as titanium dioxide or zinc oxide) or a sponge, and absorb UV radiation.

Sunscreen labelling – what to look out for

SPF stands for Sun Protection Factor and shows the degree of protection the sunscreen provides against UVB only. It is rated on a scale from 2-50+. Remember, the higher the factor, the greater the level of protection against UVB.

Protection against UVA is often indicated by a star system or a UVA logo enclosed within a circle. The higher the number of stars, the greater the level of protection.

What dermatologists recommend

Choose a broad-spectrum sunscreen with an SPF of at least 30+ for adults and 50+ for children, with high UVA protection (ideally 4 or 5 stars), and water-resistant, in addition to protective clothing and shade.

 

Most people don’t apply sunscreen correctly – here’s how it’s done:

 Correct amount: you should apply at least 1 teaspoon to each body part:

  • Head/Face/Neck
  • Each Arm
  • Each Leg
  • Your Front
  • Your Back

Correct locations: don’t forget your ears, your nose, your lips (choose a broad spectrum lip balm), your neck, the tops of your feet and (if your hair is thinning) your scalp!

Correct timing: apply sunscreen at least 20-30 minutes before you go out in the sun.

Correct frequency: reapply sunscreen frequently, at least every 2 hours and after exercising, sweating, swimming, or towel drying.

Correct use: don’t be lulled into a false sense of security! No sunscreen can provide 100% UV protection. Broad-spectrum sunscreen should be used alongside other protective measure such as clothing and shade.

Know your skin type

A person’s natural skin colour influences their vulnerability to UV damage and risk of skin cancer so it’s a good idea to know your skin type, to get a better sense of the care you need to take in the sun. More here.

Some people think a tan is healthy! NOT TRUE! A tan indicates that skin has been damaged by UV radiation, this damage is cumulative! Yes, it all adds up!

UV radiation passes through clouds, glass and water!

Just because it’s cloudy doesn’t mean you are shielded from the sun.  Over 90% of UV can pass through light cloud, at half a metre depth under water UV is still 40% as intense as at the surface, and some UV can pass through glass!  Learn more here. 

No sunbaking, no sun burning

Your risk of sunburn depends on a number of factors including: your location, the time of year and time of day. Severe sunburns, especially in childhood, can lead to skin cancer, including melanoma. So remember, no sunbaking and no sun burning.

5 steps to treating sunburn

  1. Use a moisturiser to help soothe sunburned skin. Try storing it in the fridge so it feels cool on application.
  2. Stay hydrated by drinking extra water.
  3. You may consider taking aspirin or ibuprofen to reduce swelling, redness and discomfort.
  4. If your skin blisters, leave the blisters intact to help the skin heal and to reduce the risk of infection.
  5. Take extra care to protect your skin while it heals by avoiding the sun and wearing protective clothing.

Protect your skin: Be SunSmart

UV cannot be seen or felt, so you need to defend yourself against overexposure.

Know the UV index

The UV index is a scale that was developed by the World Health Organisation which measures the UV radiation level at the surface of the Earth, and gives an indication of the potential for skin damage. It is calculated in a way that indicates the risk of developing sunburn, which is mainly caused by UVB.

When the UV index is 3 or above, protection is required.

In Ireland, make sun protection part of your daily routine particularly form April-September, when the UV index is usually 3 or above, even when it is cloudy. Stay safe by limiting time in the midday sun when UV is strongest, typically between the hours of 11:00am-3:00pm.

The UV index forecast for Ireland is included in Met Éireann’s regional weather forecasts from May to September but please be aware, that this can only be an average for any one day over the whole country. The clear/sunny sky peak UV index is reduced by cloud cover.

Remember the 5 ‘Ss’ of sun safety: Slip, Slop, Slap Seek, Slide

  • Slip on clothing: Cover skin as much as possible e.g. wear long sleeves, collared t-shirts, clothes made from close-woven material that does not allow sunlight through.
  • Slop on broad-spectrum (UVA/UVB) sunscreen with a sun protection factor (SPF) of at least 30+ for adults and 50+ for children, with high UVA protection, and water resistant. Reapply regularly.
  • Slap on a hat with a wide brim: Protect your face, ears and neck.
  • Seek shade: Sit in cover of trees to avoid direct sunlight and use a sunshade on your buggy or pram. Keep babies and children out of direct sunlight.
  • Slide on sunglasses with UV protection. Guard your eyes from harm!
