Summer isn't just about fun in the sun. While enjoying outdoor activities like barbecues or beach days, prolonged sun exposure can pose serious risks to your health.
Dermatologists caution that the sun's ultraviolet (UV) rays not only cause sunburn but also increase the risk of skin cancer over time.
"Sunburn isn't just uncomfortable—it's very harmful," Dr. Harvey Lui, a dermatology professor at the University of British Columbia, explained. He likened sunburn to being scalded, emphasizing that it damages the skin and increases the risk of developing melanoma, a deadly form of skin cancer.
Exposure to UV rays damages DNA molecules in the skin, leading to the development of abnormal cells and potentially cancerous growths. Even a single severe sunburn can double the risk of skin cancer later in life.
When skin darkens or tans, it's actually a protective response to UV exposure, indicating that the skin is trying to shield itself from further damage.
Sunburns aren't just caused by the sun; artificial UV light from tanning beds can be equally damaging, doctors warn.
Sunburn manifests as reddened, inflamed skin that appears within hours of UV exposure. Symptoms include warmth, pain, itching, and sometimes swelling or blisters. Severe cases may cause headaches, fever, nausea, or fatigue.
To alleviate sunburn discomfort, dermatologists recommend cooling the skin with cold water-soaked towels and applying soothing products like aloe or ointments available over-the-counter. Nonsteroidal anti-inflammatory drugs like Ibuprofen can help manage inflammation. In severe cases, a healthcare professional might prescribe topical corticosteroids.
Hydrating the skin with lightweight moisturizers aids in healing, but avoid heavy products or clothing that trap heat, which can worsen the burn.
Preventing sunburn is crucial for maintaining skin health. Dermatologists advise the following measures:
- Apply sunscreen with SPF 30 or higher.
- Seek shade when outdoors, especially during peak sun hours (10 a.m. to 4 p.m.).
- Wear protective clothing, including sunglasses and hats with wide brims.
- Even on cloudy days, UV rays can penetrate clouds, so remain vigilant about sun protection.
By following these precautions, you can significantly reduce the risk of skin cancer, premature skin aging, and other sun-related skin issues.
