The belief that clouds and rain save us from the effects of the sun is quite common.But the data and experts make it clear that ultraviolet radiation is still present even on days when the sun isn't shining. Many people, seeing overcast skies or rainy days, let their guard down and skip sunscreen, which can have serious consequences for skin health.
In recent years, various organizations and specialists in dermatology have insisted on The importance of protecting yourself from UV radiation regardless of the weatherAlthough UV rays are invisible, they reach the Earth's surface even in cloudy conditions, so the risk of skin damage remains year-round.
Do clouds block UV rays?
Clouds partially attenuate the amount of ultraviolet radiation that reaches us, but they do not eliminate it.Even on rainy days or when the sky is overcast, a significant percentage of UV rays pass through clouds and continue to impact the skin. Furthermore, reflections off surfaces like water, sand, or snow can increase exposure, causing the effects to persist even when not directly facing the sun.
In fact, daytime light, even when accompanied by clouds or precipitation, is still a source of ultraviolet radiation. This radiation can damage skin cells and increase the risk of developing diseases such as skin cancer, a problem that not only affects older people but is increasingly being detected in younger people.
Sun protection: an essential daily routine
Experts stress the need to maintain photoprotection habits throughout the year, not just in the summer or on clear days. Daily use of sunscreen, along with protective clothing such as caps, hats, and long sleeves, is essential to minimize cumulative sun damage. It's recommended to apply the product to all exposed areas and reapply every two hours, especially if you're active outdoors or in contact with water.
Furthermore, the importance of Use broad-spectrum sunscreens with a high protection factor (minimum SPF 30, ideally SPF 50+), capable of protecting against both UVA and UVB rays. UVA radiation is responsible for premature aging and also contributes to skin cancer, while UVB is the main culprit for sunburn.
UV radiation passes through ordinary windows and glass.
One of the lesser-known aspects is that Ultraviolet radiation can pass through conventional windowsUnless glass has specific UV-blocking treatments, the light entering offices, homes, or vehicles continues to expose the skin to these harmful effects. Therefore, dermatologists insist that sunscreen should also be applied when spending time in well-lit indoor spaces.
In some countries, proximity to the equator or certain atmospheric conditions mean that ultraviolet radiation levels are particularly high year-round, regardless of the season. Skin cancer rates in these regions are often higher, prompting doctors and associations to promote awareness campaigns to emphasize the importance of daily skin care.
Towards safer and more environmentally friendly protection
Apart from the effectiveness in sun protection, The selection of environmentally friendly products is also a relevant aspect.It's recommended to choose sunscreens with eco-friendly ingredients, as compounds like sulisobenzone have been identified as harmful to marine ecosystems and biodiversity. These ingredients can reach the ocean and affect corals and aquatic life, so choosing formulas without harmful substances is essential to take care of both your own health and that of the planet.
Likewise, it is advisable to pay attention to product labels and purchase them from trusted stores to ensure their quality and safety. Sunscreens are not just another cosmetic; they should be considered a preventive medical tool and, therefore, should be used responsibly and consciously.
Protection against ultraviolet rays should be considered an essential habit at any time of the year, regardless of whether the sky is clear or overcast.Radiation passes through clouds and windows, and its impact on the skin can have cumulative and serious consequences. Adopting daily sun protection routines and choosing appropriate products, both for your health and the environment, is key to reducing risks and enjoying the outdoors with peace of mind.
