Sun Protection: Myths and Facts

Summer in Portugal: A Land Soaked in Sunshine

Summer has arrived in Portugal, and tourists are flocking to this sun-kissed land to enjoy a well-deserved vacation. Whether you’re visiting or fortunate enough to call Portugal home, one thing is certain: the sun is a major draw.

Portugal’s allure extends beyond its stunning beaches and vibrant cities; it’s the abundance of sunshine that truly sets this country apart. With over 3,000 hours of sunlight per year, Portugal is a haven for sunseekers, offering endless opportunities to soak up the warmth and bask in the golden rays.

Sun can be harmful to our skin

Sunlight is wonderful, but it can also be harmful to our skin. Too much exposure to UV radiation can lead to sunburn, premature aging, and even skin cancer. Fortunately, we can protect ourselves from this with sunscreen, clothing, and by being smart about the sun. In this text, we will list the facts and myths about sun protection.

Myths and facts about sun protection

Myth: Children need the same sun protection as adults.

Wrong! Children’s skin is much more sensitive to UV radiation than adults’. If they burn, they are more likely to develop skin cancer later in life. Therefore, always use a sunscreen with an SPF of at least 30 for children and keep babies under 1 year old out of the sun altogether.

Fact: You also need to protect yourself if it’s cloudy or you’re in the shade.

Right! UV radiation penetrates clouds and is also reflected by sand, water, and snow. So even if you’re not in direct sunlight, you can still get burned. Therefore, always apply sunscreen if you are going outside for more than 15 minutes.

Myth: You can’t get sunburned on a cold day.

Wrong! The amount of UV radiation that reaches the Earth has nothing to do with the temperature. So you can also get sunburned on a cold winter day. Note: snow and ice reflect UV radiation extra, so the sun’s strength can be higher than you think.

Fact: Clothing protects against the sun.

Right! Most clothing items protect well against UV radiation. However, note that the lighter the color and the thinner the fabric, the more UV radiation can pass through. For example, a white T-shirt has an SPF of 15. Are you going outside for a long time or is your skin sensitive? Then there is special UV-protective clothing with an SPF of 50, which even protects you when it is wet.

Myth: You need a tanning bed for vitamin D.

Wrong! You can also make vitamin D by going in the sun. 15-30 minutes a day with your face, hands, and forearms uncovered in the sun is sufficient for most people. Note: children should always be protected with sunscreen.

Myth: Protection is not necessary if I am sitting behind glass.

False! There are two types of UV radiation: UVA and UVB. UVB radiation can cause direct damage and does not penetrate glass. UVA radiation, on the other hand, does come through glass, albeit to a lesser extent. This radiation can penetrate deep into your skin and lead to premature aging and skin cancer in the long term. So protect yourself even if you are sitting in the sun behind glass for a long time, for example during a long car ride.

Myths and facts about sunscreen

Myth: Sunscreen is carcinogenic.

Wrong! Sunscreen contains substances that protect you from UV radiation. These substances have been extensively tested and found to be safe. There are strict European regulations for the production of sunscreen, which prohibit carcinogenic substances.

Fact: A cheap sunscreen is just as good as an expensive brand.

Right! The effectiveness of sunscreen has nothing to do with the price. The price differences are often due to extra ingredients, such as perfume or dyes. Choose a sunscreen with an SPF of at least 30 and a UVA filter, regardless of the price.

Myth: Applying once a day is enough.

False! Apply sunscreen every 2 hours, or more often if you have been swimming, sweating, or drying yourself off. Note: Sunscreen loses its effectiveness over time, so reapply even if you are in the sun for a long time, even if you are using water resistant sunscreen.

Fact: Sunscreen does not last for years.

Right! Most sunscreens have a shelf life of 12 months after opening.

Fact: You need to apply sunscreen even with a dark skin tone.

Right! People with dark skin tones burn less quickly than people with light skin tones, but they can still burn. So always apply sunscreen, regardless of your skin tone.

Myth: With waterproof sunscreen, you only need to apply once a day.

False! Waterproof or water resistant means that the sunscreen stays on your skin better when swimming, but it does not mean that you do not need to reapply it. Always reapply after swimming, sweating, or drying off, even if you are using water resistant sunscreen.

More myths

By sun training, you get used to the sun and don’t need sunscreen anymore. This is not true. Your skin may burn less quickly, but that does not mean you are protected from the harmful effects of UV radiation. Keep applying sunscreen

It’s not a big deal to get a little sunburned. This is false. Sunburn is harmful to your skin and can lead to skin cancer in the long term. Prevent sunburn by protecting yourself with sunscreen, clothing, and being smart about the sun.
We didn’t need sunscreen in the past because we handled the sun more naturally. This is not true. The sun has always been harmful to our skin. Nowadays, we live longer and go on vacation to sunny areas more often, which means we are exposed to more UV radiation. So protection is more important than ever.
You need to receive UV light in your eyes. When you wear sunglasses, you make sure that you will never be able to see well in light. This is not true. Sunglasses protect your eyes from the harmful effects of UV radiation, which can lead to cataracts and macular degeneration. Always wear sunglasses with UV protection when you go out in the sun.
It’s not smart to wear sunglasses in the morning because your brain will think it’s evening. This is not true. Wearing sunglasses in the morning has no effect on your biological clock. Always protect your eyes from the sun, regardless of the time of day.

Mineral vs. Chemical Sunscreen: Unveiling the best choice for sun protection

As the sun graces us with its warmth and radiance, it’s crucial to shield our skin from its harmful UV rays. Sunscreens come in two main varieties: mineral and chemical, each with its own unique characteristics and benefits. Understanding the differences between these two types can help you make an informed decision about which sunscreen is best suited for your needs.

Mineral Sunscreen: A physical barrier against UV rays

Mineral sunscreens, also known as physical sunscreens, act as a physical barrier on the skin, reflecting UV rays away from the body. The active ingredients in mineral sunscreens, typically titanium dioxide and zinc oxide, sit on top of the skin, creating a protective shield.

Advantages of mineral sunscreen

Broad-spectrum protection: Mineral sunscreens offer broad-spectrum protection against both UVA and UVB rays, the primary culprits of sun damage and skin cancer.
Immediate protection: Mineral sunscreens provide immediate protection upon application, eliminating the need for a waiting period before venturing into the sun.
Safe for sensitive skin: Mineral sunscreens are generally considered safe for sensitive skin, as they are less likely to cause irritation or allergic reactions.

Drawbacks of mineral sunscreen

White cast: Mineral sunscreens can leave a white or zinc cast on the skin, especially when applied generously. This can be a cosmetic concern for some individuals.
Thicker consistency: Mineral sunscreens tend to have a thicker consistency than chemical sunscreens, which some may find less pleasant to apply.

Chemical sunscreen: Absorbing UV rays for defense

Chemical sunscreens work by absorbing UV rays and converting them into heat, which is then released from the skin. The active ingredients in chemical sunscreens penetrate the skin’s outer layers, where they intercept and neutralize UV radiation.

Advantages of chemical sunscreen

Lightweight and easy to apply: Chemical sunscreens typically have a lightweight, non-greasy texture that is easy to spread and blend into the skin.
Less visible on the skin: Chemical sunscreens generally do not leave a white cast on the skin, making them a popular choice for those who prefer a more natural look.
Water-resistant options: Many chemical sunscreens are available in water-resistant formulas, making them suitable for water activities and sports.

Drawbacks of chemical sunscreen

Potential for irritation: Some chemical sunscreens may contain ingredients that can irritate sensitive skin.
Waiting period for protection: Chemical sunscreens typically require 15-20 minutes after application to reach full effectiveness.

Choosing the right sunscreen for you

The best sunscreen for you depends on your individual needs and preferences. Consider factors such as your skin type, sensitivity level, desired level of protection, and cosmetic preferences when making your decision.

For those with sensitive skin or those who prefer immediate protection, mineral sunscreens may be a good choice. If you prefer a lightweight, non-greasy sunscreen that blends well into the skin, chemical sunscreens may be a better option.

Regardless of the type you choose, ensure that the sunscreen you select has an SPF of 30 or higher and provides broad-spectrum protection against UVA and UVB rays.

Additional tips for sun safety

Check the sun index: The sun index is a measure of the intensity of UV radiation at the Earth’s surface. It is a good idea to check the sun index before going outside and to take extra precautions if the index is high.
Seek shade during peak sun hours: The sun is strongest between 10 AM and 4 PM. If possible, seek shade during these hours, especially for babies and young children.
Stay hydrated: Drink plenty of fluids to stay hydrated, especially when you are spending time in the sun.
Be aware of medications: Some medications can make your skin more sensitive to the sun. Talk to your doctor about any concerns you have.
Regularly examine your skin: Check your skin for any new or changing moles or spots. If you notice anything unusual, see a doctor right away.

By following these tips, you can help protect yourself from the harmful effects of the sun and enjoy the outdoors safely.

Sun protection for children

Here are some tips to keep your child safe in the sun:

Seek shade: Keep your child out of the sun between 12 PM and 3 PM. The sun’s intensity is highest during this time, and your child’s skin can burn faster. Seek shade during this period. However, even in the shade, you can still get burned, so always apply sunscreen to your child.
Cover up: Protect your child with (UV-protective) clothing. Regular, loose-fitting, and breathable clothing usually provides good protection. Think about clothes with long sleeves and pants.
Hats and sunglasses: A hat or cap provides good protection for the face, head, neck, and ears. A good pair of sunglasses protects their sensitive eyes.

All about sunscreen

Sunscreen comes in many varieties. What should you consider when buying sunscreen? And how do you know it’s good? How long can you actually store it? Here you will find all the information about sunscreen.

Choosing a good sunscreen

Everyone’s skin is different. How quickly your skin tans in the sun is hereditary and doesn’t change, regardless of how much time you spend in the sun.

Sun Protection Factor (SPF)

When buying sunscreen, consider the appropriate SPF for your skin type. The sun protection factor is indicated by SPF (Sun Protection Factor) on the packaging. It’s best to use at least SPF 30 with a UVA filter.

Sunscreen for children

The recommendation for children is also to use a minimum SPF of 30 with a UVA filter. Keep babies under 1 year old out of the sun completely.

Skin type

Your skin type is determined by the amount of pigment in your skin. There are different skin types. The lighter your skin, the faster you burn. Here’s a general rule: protect yourself with at least SPF 30.

UV radiation and sun index

Sunlight partly consists of UV radiation. This radiation can burn your skin. The sun index indicates how much UV radiation reaches the Earth and how quickly you can burn in the sun. You should definitely protect yourself from the sun from a sun index of 3. From a sun index of 5, the risk of skin damage is high. It’s best to stay out of the sun as much as possible at this point.

I hope this information helps you enjoy the sun safely while being in Portugal and develop a healthy tan while taking care of your skin!
