A doctor has urged people to make a simple yet crucial habit: checking the UV index on their phone every day. This seemingly small act can significantly reduce the risk of developing skin cancer, a deadly disease that tragically claims the lives of over 3,000 people in the UK annually.
Dr. Karan Rajan, an NHS surgeon and widely recognized online as Dr. Raj, stresses the importance of understanding the UV index, which is readily available on most weather apps. The UV index provides a numerical representation of the strength of the sun’s ultraviolet radiation, with higher values indicating a greater potential for skin and eye damage.
Dr. Raj emphasizes that sunscreen application should not be solely based on the intensity of the sun’s warmth, as UV rays, even on seemingly cool days, can still cause harm. He stresses that for individuals with fair skin, daily sunscreen application is recommended, particularly when the UV index reaches 3 or above. However, those with darker skin may only need to wear sunscreen when the UV index is significantly higher, like 7 or 8, especially if they plan to be in the sun for extended periods.
The World Health Organization (WHO) highlights the critical role of UV radiation in the development of skin cancer, emphasizing that excessive exposure, even from artificial sources like tanning beds, can significantly increase the risk. The WHO advises seeking shade during midday hours when the UV index is between 3 and 7, and strongly recommending avoiding direct sun exposure altogether when the UV index is 8 or above.
Remember, even if you don’t feel the sun’s heat, its harmful UV rays can still damage your skin. By making a conscious effort to check the UV index and taking appropriate precautions, you can significantly reduce your risk of skin cancer and protect your health and well-being.
