A moderate UV index of level 4 is forecast for the city of Buenos Aires and the suburbs of Buenos Aires due to cloud cover and likely showers, providing a reprieve from recently recorded days of extreme radiation.
In the rest of the countrypredicts the National Meteorological Service “extreme” radiation rates (11+) in the north and “very high” values in the center, while in areas with severe weather such as the Northeast, values will be lower.
What is the UV index and why is it important for health?
The UV index (IUV) is an international standard that measures the intensity of ultraviolet solar radiation. that reaches the surface of the earth at a specific place and time. According to the World Health Organization (WHO), this scale starts at 0 and has no upper limit Values above 11 are considered “extreme”. Their main function is to warn the population of the need for protective measures, as the intensity of these rays varies depending on altitude, latitude, ozone layer and cloud cover.
Authoritarians don’t like that
The practice of professional and critical journalism is a mainstay of democracy. That is why it bothers those who believe that they are the owners of the truth.
It is important to know the daily rate because, unlike heat, UV radiation is not immediately noticeable on the skin.. The Pan American Health Organization (PAHO) emphasizes that radiation levels can be high enough to cause damage, even on cloudy or cool days. When people are informed, they can plan their outdoor activities while minimizing exposure at the highest risk times, which are usually between 10 a.m. and 4 p.m.
The danger of the sun’s ultraviolet rays to health
Excessive and unprotected exposure to UV rays has serious and cumulative consequences for the body.. The WHO warns that radiation is the leading cause of skin cancer, both melanoma and skin carcinoma. In addition, it can lead to acute sunburn, premature skin aging (photoaging) and a weakened immune system, which limits the body’s ability to defend itself against certain diseases.
Beyond the dermis, The eyes are also at significant risk. PAHO points out that UV radiation can cause acute eye diseases such as photokeratitis (a painful inflammation of the cornea) and chronic problems such as cataracts, which are the leading cause of blindness worldwide. For this reason, Care must be comprehensive and protect both the body surface and vision too high radiation.
To protect yourself effectively, the WHO and PAHO recommend Avoid direct sunlight during the middle hours of the day. It is advisable to seek shade and wear clothing that covers most of the body, such as long-sleeved shirts and dark, tight-fitting pants. Additionally, it is important to wear wide-brimmed hats that protect the face, ears, and neck, as well as wraparound sunglasses with certified UV filters.
Using sunscreen is another important measure– A product with a sun protection factor (SPF) of 30 or higher should be applied to all exposed skin areas. The experts recommend applying it 20 minutes before going out and reapplying every two hours.or more commonly after swimming or sweating. These measures are particularly important for children and adolescents, as sun damage in childhood dramatically increases the risk of developing serious illnesses in adulthood.
