In recent days, several regions of the Iberian Peninsula have experienced a significant rise in temperature, resulting in weather conditions more akin to summer than spring. For this reason, it is crucial to take protective measures against sun exposure to prevent potential skin problems.
On ultraviolet rays (UV), emitted by the sun, are the main causes of skin damage, so it is essential to understand what they consist of and what the tips to protect our skin against the harmful effects of these rays. To learn more about the importance of protection, it is advisable to review how it relates to the UV radiation.
Ultraviolet rays are a type of electromagnetic radiation found in sunlight that can penetrate the Earth's surface.This radiation is classified into three categories: UVA, UVB, and UVC. UVA rays, with wavelengths ranging from 320 to 400 nanometers (nm), are particularly dangerous. They can penetrate deep into the skin and are linked to premature aging and skin cancer.
On the other hand, UVB rays (290-320 nm) do not penetrate as deeply, but are primarily responsible for causing sunburn and skin redness. Research has shown that prolonged UV exposure may be the main cause of skin cancer. It is vital to protect yourself from this radiation to avoid serious and potentially irreversible skin damage.

Tips to protect your skin from UV rays
It is essential to avoid sunbathing during the central hours of the day, which are usually between 10:00 a.m. and 4:00 p.m., when solar radiation is most intense. It is also advisable to use sun creams with an appropriate sun protection factor (SPF) to help protect your skin. Here are some additional recommendations:
- Use broad spectrum sunscreen: Apply sunscreen with an SPF of at least 30, even on cloudy days, and be sure to cover all exposed areas.
- Look for the shadow: Taking shelter under trees, umbrellas, or buildings can significantly reduce your exposure to UV radiation.
- Wear protective clothing: Opt for long-sleeved clothing, pants, and wide-brimmed hats to cover your skin.
- Protect your eyes: Wear sunglasses that block 100% of UVA and UVB rays. This will not only protect your eyes, but also the delicate skin around them. Remember that eye protection is essential to avoid long-term problems.
As the summer season approaches, when many people visit beaches and pools, it is crucial to reinforce these protective measures. Remember that prevention is essential to avoid skin problems that can appear over the years and can seriously affect the health of the skin.
Understanding Ultraviolet Radiation
La ultraviolet radiation It is a form of energy emitted by the sun, and it has a significant impact on human health. There are different types of UV rays, which vary according to their wavelength:
- UVA radiation: These rays are responsible for tanning and contribute to skin aging, as well as some types of skin cancer. They penetrate deep into the skin.
- UVB radiation: They are the most dangerous for the skin's surface, causing sunburn. They also play a crucial role in the development of skin cancer.
- UVC radiation: Although they are the most dangerous of the three types, most are absorbed by the ozone layer and do not reach the Earth's surface.
Exposure to UV rays also has benefits, such as the synthesis of vitamin D, which is vital for bone health and the immune system. However, excessive exposure can have negative consequences, such as premature aging, eye damage, and an increased risk of skin cancer.
To better understand the phenomenon, it is useful to know the impact of damage to the ozone layer in the UV radiation that reaches us.
Effects of UV radiation on eye health
La ultraviolet radiation UV radiation also has a significant impact on eye health. UV exposure can contribute to the formation of cataracts, pterygium, and retinal damage. It's advisable to wear sunglasses that offer adequate UV protection to help prevent these problems in the long term.
To protect your eyes, choose sunglasses that block 100% of UVA and UVB rays. This is especially important for outdoor activities and on sunny days, as UV radiation can damage the skin around the eyes and contribute to the formation of wrinkles and dark spots.
The ultraviolet (UV) index
El ultraviolet index (UVI) is a measure of the level of UV radiation at a given time. This index can vary depending on factors such as latitude, season, time of day, and the amount of ozone in the atmosphere. A higher UVI indicates a greater risk of skin damage, so it's crucial to be informed about daily UV radiation conditions.
UV Index data is often reported in weather reports, allowing people to make informed decisions about their outdoor activities and the need for adequate sun protection.

The importance of prevention and self-care
With increasing exposure to UV radiation, it's essential to implement strategies to help protect our skin and health. Some additional tips include:
- Perform skin checks regularly: Visit a dermatologist for routine checkups to detect any changes in your skin.
- Avoid tanning beds: These artificial sources of UV can be as harmful as natural sun exposure.
- Moisturize your skin: Use moisturizers to help keep your skin soft and protected after sun exposure.
The key to enjoying the sun safely lies in prevention and consistent skin care. By implementing these strategies, you can significantly reduce your risk of long-term skin problems.
