Based on the National Meteorological Service (SMN) scale, values of “very high” to “extreme” in large parts of Argentina. This highly radiation landscape requires special protection as unprotected skin and eyes can burn within minutes.

What is the UV index and why is it important for health?
He World Solar UV Index (WUI) is an internationally standardized measurement sponsored by the World Health Organization (WHO) that describes the intensity of the sun’s ultraviolet (UV) radiation on the Earth’s surface that affects human skin. The IUV is expressed on a numerical scale, ranging from the value 0 (zero), indicating the maximum radiation intensity on a given day, which generally occurs near solar noon.
Its values are divided into categories: low (<3), moderate (3-5), large (6-7), very high (8-10) And extreme (11+). Knowing the value of the index is crucial for health because the higher the number, the greater the chance of injury to the skin and eyes and the shorter the time for damage to occur. WHO recommends the use of protective measures when the index reaches a value of 3 or higher.
The danger of the sun’s ultraviolet rays to health
Excessive and unprotected exposure to the sun’s ultraviolet (UV) rays poses a danger significant health riskwith consequences ranging from immediate effects to chronic illness. Sun damage begins at a young age and increases over the course of life, primarily affecting the skin and eyes.
The main dangers include Skin cancerMelanoma is the most serious form and one of the main causes of death from skin cancer. Chronic exposure also leads to premature skin aging (photoaging), which manifests as wrinkles, loss of collagen, brown spots and thickened skin. In addition, UV radiation plays a role Risk in developing CataractsClouding of the lens, which can lead to blindness if left untreated, and other eye diseases.
Sun and temperature rise in CABA, instability and heat in northern Argentina
To counteract these harmful effects, the Pan American Health Organization (PAHO) and the WHO recommend the implementation of a number of important preventive measures, especially during hours of high or extreme UV index. The golden rule is Limit sun exposure to 10 a.m. to 4 p.m.Actively seek shade and not just rely on the feeling of heat, because sunburn is caused by imperceptible UV rays.
Protection must be comprehensive: the use of Protective clothing (e.g. long-sleeved shirts), wide-brimmed hats that cover the face, neck and ears, and sunglasses with certified 99-100 percent protection against UVA and UVB rays. Apply generously to exposed skin areas Sun protection A sun protection factor (SPF) equal to or greater than 30 (or 15 according to some sources) should be done 30 minutes before sun exposure and renewed every two hours.
