Americans in 17 states are being advised to stay out of the sun today, as elevated UV radiation levels pose serious health risks. According to the Environmental Protection Agency (EPA), the ultraviolet (UV) index in these regions is expected to reach extreme levels, which could significantly increase the risk of skin burns, eye damage, and long-term health issues such as skin cancer.
The warning covers a wide range of states, including California, Nevada, Arizona, Texas, and Florida, with solar noon expected to bring the highest radiation levels. Health experts are urging the public to exercise caution and adopt safety measures to protect themselves from harmful sun exposure.
What’s Behind the Extreme UV Radiation?
On Thursday, July 10, the UV index forecast indicated that parts of these states could see UV levels at or above 11, marking an extreme risk of harm from sun exposure.
The UV index scale ranges from 1 to 11+, with the highest levels associated with significant risks to skin and eye health. When the UV index hits 11+, unprotected skin can burn in a matter of minutes, leading to sunburns and increasing the likelihood of developing melanoma skin cancer over time.
According to the EPA, the solar noon, the time when the sun is at its highest point in the sky, will be particularly dangerous in several areas.
The warning affects states across the US, such as California, Nevada, Utah, Arizona, Colorado, New Mexico, Texas, Oklahoma, Kansas, Arkansas, Mississippi, Louisiana, Alabama, Georgia, Florida, North Carolina and Virginia
Residents are advised to limit outdoor activities and take precautions like wearing SPF 30+ sunscreen, protective clothing, and sunglasses. Experts highlight the long-term implications of repeated sun exposure, warning that it can accelerate photoaging and increase the risk of skin cancer.
Antony Young, an emeritus professor of dermatology at King’s College, London, explains that the UV index is a direct indicator of the sunburning potential of sunlight.
“The UV index [UVI] is a measure of the sunburning power of sunlight. … The higher the UVI, the shorter the time you need in the sun to burn.” he said.
Protecting Yourself from Harmful UV Radiation
With the UV index reaching extreme levels, taking appropriate precautions is essential. The EPA advises avoiding the sun between 10 a.m. and 4 p.m., the time when UV radiation is most intense. It is also recommended to seek shade and reapply sunscreen every two hours for continued protection.
For maximum safety, wearing a wide-brimmed hat, long sleeves, and sunglasses can further shield the skin and eyes from harmful rays.
Richard Weller, a professor of dermatology at the University of Edinburgh, underscores the importance of these protective measures, noting that sunburn is not just an immediate concern but a risk factor for melanoma, the most serious form of skin cancer.
While many people may associate sunburn with immediate discomfort, the long-term effects can be severe, particularly for those who spend a lot of time outdoors without proper protection.
