Why do we need UV protection?
Summer is the time for vacations and holidays, a period in which we want to escape responsibilities and relax. However, it is also the time when our skin suffers the most due to the action of ultraviolet radiation. We need to know that there are two types of UV rays. The first type, UVA rays, are constant and present even on cloudy days. They penetrate the dermis and can cause several negative effects by producing free radicals. The most visible effect is skin aging, resulting in loss of elasticity and the appearance of wrinkles. UVA rays can also cause sun intolerance, manifested by erythema, itching, polymorphic light eruption, and the appearance of spots.
According to medical studies, these types of rays (UVA) are responsible for certain types of skin cancer. UVB rays account for approximately 5% of the ultraviolet radiation reaching the Earth. They are stronger and reach the epidermis. These rays are responsible for tanning but can also cause sunburn, allergic reactions, and certain forms of cancer. The recommended sun protection is sunscreen with a high protection factor. It is advisable to apply sunscreen before sun exposure, using a sufficient amount. After sun exposure, it is recommended to use a moisturizing cream. However, sunscreen is not the only way to protect ourselves from the sun’s rays.
Appropriate Clothing
Proper clothing plays an important role in providing optimal protection. Clothes made of natural materials, lightweight fabrics, hats, and sunglasses create a barrier against ultraviolet radiation. Direct sun exposure should be avoided between 11:00 AM and 3:00 PM when solar radiation intensity is at its highest.
Effective Hydration
During summer, it is recommended to consume an adequate amount of water to meet the increased needs of our body. Otherwise, there is a risk of dehydration and an increase in oxidative stress at the cellular level.
Correct Nutrition
Certain foods have a high content of antioxidants, which help protect us from the sun. Antioxidants prevent premature cell death by inhibiting the oxidation of cells through the neutralization of free radicals. Free radicals are by-products of metabolic processes and energy production resulting from respiratory and inflammatory processes, as well as external factors such as pollution, radiation, smoking, and alcohol consumption. Foods to be consumed during summer to help our body fight against the harmful effects of UV radiation include red, orange, green peppers, zucchini, carrots, especially cooked tomatoes as they release lycopene, a substance that protects the body from sunburn. Olive oil, Omega-3 fatty acids from fish, dark chocolate, and leafy green vegetables are a few examples of foods that should be consumed during summer to prevent the harmful effects of UV radiation.
Alternatives to Sunscreen
If you are reluctant to use commercially available sunscreens, there are natural alternatives such as sea buckthorn oil, sesame oil, olive oil, coconut oil, cocoa butter, and aloe vera gel that can protect the skin.
Photosensitizing Medications
There are medications that can cause allergic reactions following exposure to ultraviolet radiation, and it is important to be aware of this. Photoreaction varies depending on the dose, intensity of exposure, type of substance, and polypharmacy. Some of these medications include antibiotics (e.g., Doxycycline, Tetracycline, Ofloxacin, Ciprofloxacin, Pefloxacin, Norfloxacin, Lomefloxacin), nonsteroidal anti-inflammatory drugs like Ibuprofen, Naproxen, Tenoxicam, certain antidiabetic medications, antiemetic medication, etc. In conclusion, it is important to mention that achieving the perfect tan and maintaining healthy skin does not only depend on applying a simple sunscreen but involves several steps that go beyond the end of the summer season.
