There’s still a few weeks left for summer to officially begin, but rising temperatures and increasing spring daylight hours are more than enough for a good portion of the Spanish to fill up on beaches and swimming pools. . Everything to take the first dip of the season and try to catch the first rays of the sun, to catch some color and be the envy of everyone in the office.
but Sunbathing is not without its dangers, and it is that there are a series of recommendations that we should keep in mind before exposing ourselves to Star King. Not only to protect our skin from burns today, but also to avoid serious health problems in the future.
Although we don’t see it, solar radiation is present and travels from the star itself to the Earth’s surface. It is made up of three types of ultraviolet radiation (UV), called UV-A, UV-B and UV-C rays according to their wavelength, in addition to infrared rays.
- UV A, It is the majority radiation, specifically it accounts for 95% of the ultraviolet radiation affecting our skin. It’s not the most harmful, but it can cause skin changes like premature aging, wrinkles or spots.
- UV-B. It is radiation that burns our skin, which is responsible for sunburn when we sunbathe or do not apply enough sun protection on our skin.
- UV c, Undoubtedly, this is the most harmful radiation for man, but fortunately it does not enter the atmosphere and therefore does not reach the surface of the Earth.
- infrared rays. They are a type of radiation that neither burns nor dissipates, it only gives us heat. Exposing oneself to them does not have dire consequences for humans either.
Beware of Melanoma
Of all the types of skin cancer, melanoma is by far the most dangerous. And the main risk factor for its presence is excessive exposure to solar radiation, those UV-A and UV-B rays that have the potential to alter the structure of our DNA.
In Spain alone, five thousand new cases of melanoma are diagnosed each year, with more than 13 new cases every day. Most of them are in people between 40 and 70 years old. It is in our hands to stop it.
Importance of checking UV index
When we are going to spend a day at the beach the normal thing is that we consult the weather forecast: max temperature, min, forecast… a very important value, forget to consult the UV index. A value that goes from 0 to 11 and appears broken up by hours in most telephone applications and web pages, tells us at each moment how much harmful radiation from the Sun is reaching the Earth’s surface. Knowing this value is essential to be able to decide what type of protection to apply and whether it is a good time to sunbathe. For example, it may happen that when we go to the beach we do not see the sun because the sky is completely covered, we think that it is not necessary to apply sunscreen because the sun is not visible, but in spite of the UV The index is too high and we end up burning ourselves..
UV Index Scale
low risk, Values 0, 1 and 2. Usually those are the values we have in the summer in the first hour of the day and last. It is completely safe to walk in the sun at this time.
Medium risk, Values 3, 4 and 5. It is not uncommon in the summer that at 11 in the morning we already have an ultraviolet index of 3 or 4. Here sun protection cream is already necessary if we haven’t applied it yet, and it is also recommended to wear a hat and sunglasses.
high risk. Values 6 and 7. If our phone tells us that the UV index is in these values, we should be careful: we are reaching the limit of sun exposure, even if we wear sun protection cream.
too much risk. Values 8, 9 and 10. From the index of 8, we will now talk not only about photoprotection, but also about photo protection. It’s time to put yourself under an umbrella or, better yet, leave the beach and be in the shade.
excessive risk. Price 11. But still on the beach? It’s been at least three points since you were released.
