Sunlights can have both positive and negative effects on our skin. While getting an adequate amount of sun can serve as a source of Vitamin D and enhance skin health, prolonged exposure to intense sunlight can lead to serious negative outcomes such as sunburn and skin cancer.
Benefits and Harms of Sunlight
Sunlight is a crucial source of Vitamin D, which is essential for bone health and immune system function. When the cholesterol in our skin is exposed to UVB rays, it triggers the synthesis of Vitamin D in the body. Feeling more energetic, happier, and positive on sunny days is directly related to the sunlight's ability to elevate serotonin levels, thus improving mood and reducing depression symptoms. Additionally, sunlight strengthens the immune system by increasing the activation of immune cells and providing protection against certain diseases. Sunlight also regulates the secretion of the sleep-regulating hormone melatonin, which, in turn, can enhance sleep quality and alleviate sleep disorders.
Despite its positive effects, excessive sun exposure comes with risks that shouldn't be overlooked. Overexposure to the sun can lead to skin burns, sunspots, wrinkles, and even skin cancer. UVB and UVA rays can cause damage to the skin tissue. Similarly, prolonged exposure to the sun can result in eye irritation, redness, and serious eye disorders. Prolonged sun exposure can also cause excessive sweating and dehydration. Intense sunlight can elevate body temperature, leading to dehydration and even heatstroke.
How Can You Protect Yourself from the Harmful Effects of the Sun?
While sunlight is important for overall health, it's crucial to avoid excessive exposure. When going out in the sun, especially during peak hours when the sun is strongest, it's important to use sunscreen, wear appropriate clothing, and use sunglasses.
Using sunscreen is one of the most effective ways to protect yourself from these harmful rays. While shielding your skin from the sun's harmful effects, sunscreen can also provide nourishment and hydration to the skin. Incorporating sunscreens with protective properties into your daily routine is essential.
What Is Sunscreen?
Sunscreen and sunblock are protective products used to prevent health issues such as skin burns, sunspots, wrinkles, and skin cancer that may result from harmful UV rays. They shield the skin by forming a barrier or absorbing harmful UV rays. They are usually labeled with a sun protection factor (SPF) value. This value indicates how long the protective layer can shield the skin from UVB rays. A sunscreen with an SPF value of 50, for example, can protect the skin from sunburns that might occur after approximately 60 times the usual sun exposure. It's important to reapply sunscreen regularly throughout the day to maintain its effectiveness.
What Should Sunscreen Contain?
When choosing sunscreen, consider the SPF value and the needs of your skin. The choice of sunscreen should also take into account a few important factors. An SPF value of at least 30 is recommended for daily use, but SPF 50 is ideal. If the skin will be exposed to the sun for an extended period or if it's sensitive, a higher SPF value might be preferable.
Sunscreen should provide protection against both UVA and UVB rays. Therefore, choose a product that offers broad-spectrum protection. Look for "UVA" and "UVB" labels or opt for products labeled as "broad-spectrum."
The ingredients of sunscreen products can vary according to skin type. If you have oily or acne-prone skin, opt for oil-free or lightweight formulas. If you're searching for sunscreen for oily skin, you can consider the Matte Sunscreen for Oily and Combination Skin, which aims to control sebum production, provide UV and blue light protection, and prevent skin from becoming oily.
If you have dry or sensitive skin, choose sunscreens with moisturizing properties. For dry skin, you can choose the High Protection and Moisturizing Sunscreen, which targets UV protection without causing skin oiliness and helps maintain the skin's moisture balance.
A sun-protective sunscreen with a formula supported by Arbutin and Niacinamide might be suitable if you're looking to prevent skin discoloration and address uneven skin tone.
How to Apply Sunscreen?
Applying sunscreen correctly and regularly ensures effective protection. It's recommended to apply sunscreen at least 15-30 minutes before going out in the sun. This allows the product to be fully absorbed by the skin and create a protective layer. Reapplication is advised every two hours or after activities involving sweating, swimming, or contact with water.
Remember that UV rays are present throughout all seasons. Therefore, sun protections should be used not only during sunny days and in the summer but also on cloudy days and during the winter. Additionally, it's important to apply sunscreen not only to your face and body but also to areas like lips, ears, and other sensitive areas that need protection. By implementing these methods and using sunscreen throughout the day, you can protect your skin from sunburns, premature aging, skin cancer, and other skin problems.
