Sun Awareness Week, celebrated this year on the 6th to 12th May, serves as an essential reminder of the need to protect ourselves from the harmful effects of the sun’s ultraviolet (UV) radiation. Celebrated in the early summer, it not only marks the transition to warmer weather but also promotes the importance of sun safety practices.
Ultraviolet (UV) radiation from the sun can cause damage to the skin and lead to skin cancer and UV exposure is the main preventable cause of skin cancer worldwide. There are over 100,000 new cases of skin cancer diagnosed each year in the UK, and this figure is continuing to rise. In addition, skin cancer kills over 2,500 people every year in the UK, making sun protection essential all year round.
Understanding the risks
The sun emits radiation in the form of UV light, which is classified mainly into two types harmful to humans: UVA and UVB. UVA rays are primarily responsible for aging the skin, leading to long-term damage such as wrinkles and sunspots. UVB rays, on the other hand, are the main cause of sunburn and play a significant role in developing skin cancer.
Overexposure to these rays can lead to various health complications. The most severe is skin cancer, including melanoma, which is highly aggressive and potentially fatal. Other conditions include eye damage such as cataracts, immune suppression, and premature aging of the skin.
Sun Awareness Week
Sun Awareness Week aims to educate the public about the potential dangers of sun exposure and promote protective measures to reduce these risks. The week is designed to spread important information about sun safety, including:
– The peak hours of harmful UV radiation (10am to 4pm).
– The importance of regular skin checks for early detection of skin cancer.
– Encouraging the use of sunscreen and protective clothing.
Education and awareness are powerful tools in the fight against skin cancer and other sun-related health issues. By dedicating a week to sun awareness, organisations and health professionals can significantly impact public health outcomes.
Sun protection tips and advice
With summer approaching, spending time outdoors becomes almost irresistible. Here are some essential tips to protect yourself from the sun’s harmful rays:
1. Use broad-spectrum sunscreen
Apply a broad-spectrum sunscreen with an SPF of at least 30 to all exposed skin, even on cloudy days. Sunscreen should be reapplied every two hours, or more often if swimming or sweating. Choose products that block both UVA and UVB rays for comprehensive protection.
2. Wear protective clothing
Long-sleeved shirts, pants, and wide-brimmed hats provide excellent physical barriers against the sun’s rays. Fabrics with a tight weave offer better protection. Some clothing is specially designed with UV protection called UPF (Ultraviolet Protection Factor), which is highly recommended for those spending extended periods in direct sunlight.
3. Seek shade
Whenever possible, seek shade, especially during the midday hours when the sun’s rays are strongest. Use umbrellas, trees, or other shelter to limit direct sun exposure.
4. Protect Your eyes
UV radiation can damage the eyes. Wear sunglasses that block UV rays to protect your eyesight and ensure they have a label stating they provide 100% UV protection.
5. Hydrate
Sun exposure and increased temperatures can lead to dehydration. Drink plenty of fluids throughout the day to stay hydrated, which also helps your skin remain resilient.
6. Avoid tanning beds
Tanning beds emit UVA and UVB rays that can increase the risk of skin cancer. Embrace your natural skin tone or use a UV-free self-tanning product if you desire a tanned look.
7. Regular skin examinations
Frequent checks of your skin for any new moles or changes to existing moles are very important. Early detection of skin abnormalities can lead to early treatment and a better prognosis.
All year round
Remember, effective sun protection is not just a summer task and it’s advisable to take precautions all year round. By following the above guidelines and integrating protective measures into your daily routine, you can enjoy the sun safely whilst minimising your health risk and protecting your skin.
