Sunlight is a natural source of ultraviolet (UV) radiation, which can damage skin cells. UV rays are among the most significant factors that contribute to the development of certain types of skin cancer, including basal cell carcinoma, squamous cell carcinoma and the notorious malignant melanoma. Therefore, it is essential for us to take necessary steps to minimise exposure to these harmful rays.
Preventing Skin Cancer
● Using Sunscreen: The use of broad-spectrum sunscreen that protects against UVA and UVB rays is crucial for guarding against skin cancer. It is recommended to use sunscreen with a sun protection factor (SPF) of at least 30 and apply it generously to all exposed skin areas, applying it at least 15 minutes before leaving home. Re-apply every 2 to 3 hours.
● Protective Clothing: Wearing long-sleeved shirts, long pants, and skirts is preferred to provide protection against sunlight. Clothing made from tightly woven fabric offers the best safeguard.
● Seeking Shade: Staying in the shade or using umbrellas and shelters can reduce exposure to harmful sun rays.
● Avoiding Peak Sun Hours: It is advisable to avoid sun exposure during the period from 10 a.m. to 4 p.m., when sunlight is at its strongest.
By following these preventive measures, you can significantly reduce your risk of skin cancer and maintain healthier skin. As a family doctor who sees lots of patients with skin concerns, I emphasise the importance of adopting these sun safety practices to protect yourself and your loved ones from the potential dangers of excessive sun exposure. I recommend individuals with high cumulative sun exposure, to have regular skin checks, at least annually. Remember that practicing sun safety not only prevents skin cancer but also contributes to overall skin health and well-being.
