How to protect against sunrays?

Protect yourself from the sun
Some people only think about sun protection when they spend a day at the lake, beach or pool. But solar radiation adds up every day and it happens every time you are in the sun. Although sunlight is the main source of UV rays, you can not completely avoid the sun. And it would be good to stay inside. But too much sun can be harmful. There are a few simple steps you can take to limit exposure to UV rays.

Simply staying in the shade is one of the best ways to limit UV exposure. When you’re in the sun, it’s slip! Slop! Slap! ® and wrap

Slip into a shirt.
Slop on sunscreen.
Hit a hat.
Wrap the sunglasses to protect the eyes and skin.
Seek shade
An obvious, but very important, way to limit your exposure to UV light is to stay out in direct sunlight for long periods of time. This is very important between 10am and 4pm when the UV light is strongest. If you are not sure how strong the sun’s rays are, use the shadow test: If your shadow is shorter than you, the sun’s rays are strongest and it’s important to protect yourself.

UV rays reach throughout the year, even on cloudy or cloudy days. However, the magnitude of UV rays may vary due to many factors (see above). UV rays can therefore be reached under the surface of the water, so you can burn even when you are in the water and feel cool.

Some UV rays can pass through windows. Typical car, home and office UVB rays. Tinted windows help block more UVA rays, but this depends on the type of tint. UV radiation that falls through the window is unlikely to pose a major risk to most people unless they spend a long time near a window exposed to direct sunlight.

Protect your skin with clothes
When you are in the sun, wear clothes to cover your skin. Clothing with a different UV protection. Long-sleeved shirts, long pants or long skirts cover most of the skin and are the most protective. Dark colors generally provide more protection than bright colors. A dense woven fabric protects better than loose woven clothing. Dry tissue is generally more protective than wet tissue.

Note that masking does not hide all UV rays. If you can see through a fabric, you can also penetrate UV rays.

Many companies today make clothing that is lightweight, comfortable and protects against UV rays when wet. It tends to be more densely woven and has UV rays. These sun protection clothing can have the UV protection factor (UPF). The higher the UPF, the higher the protection against UV rays.

Some products that are used as detergents in a washing machine can increase the value of your existing clothes. You give your clothing a UV protection layer, without the color or texture to change. This may be useful, but it is not clear how much it contributes to UV rays, so it is still important to follow the other steps here.

Use sunscreen
Sunscreen is a product that you apply to your skin to protect the sun’s UV rays. However, it is important to know that sunscreen is just a filter – it does not block all UV rays. Sunscreens should not be used to extend the time in the sun. Even with the proper use of sunscreen, some UV rays will remain. This is not your first defense line. Considering that you are in the shade and wearing protective clothing, these are not available as a first option.

Sunscreens are available in many forms – lotions, creams, ointments, gels, sprays, wipes and lip balms, just to name a few.

Some cosmetics such as moisturizers, lipsticks and foundations are sunscreen. Some make-ups contain sunscreen but do not provide sunscreen.

Read the labels
Be sure to read the label when choosing a sunscreen. Recommended are sunscreens with a broad spectrum of protection (both UVA and UVB) and a sun protection factor (SPF) of 30 or higher.

Sun Protection Factor (SPF): The SPF number indicates the level of protection sunscreen provides against UVB rays, which are the major cause of sunburn. A higher sun protection factor means more UVB protection (though it says nothing about UVA protection). For example, if you use a sun protection factor of 30 correctly, you will receive 1 minute of UVB radiation for every 30 minutes of sun exposure. An hour in the sun with SPF 30 sunscreen is the same as spending two minutes unprotected. People often do not use enough sunscreen to get less real protection.

Sunscreens with an SPF of over 100 are available. Higher numbers mean more protection, but many people do not understand the SPF scale. Sunscreens with SPF 15 filter out about 93% of UVB rays, while sunscreens with SPF 30 filter out about 97%, sunscreens with SPF 50 about 98% and SPF 100 about 99%. The higher you go, the smaller the difference becomes. No sunscreen completely protects you.

In the US, sunscreens with an SPF of less than 15 now need to include a warning on the label stating that the product can only be used to prevent sunburn, but not skin cancer or premature aging.

Broad-spectrum sunscreen: Sunscreen products can only be described as “broad spectrum” if they have been tested and proven to protect against both UVA and UVB rays. The ingredients of sunscreen that protect against UVA radiation include avobenzone (Parsol 1789), zinc oxide and titanium dioxide.

Only broad-spectrum sunscreens with an SPF of 15 or higher can help protect against skin cancer and premature aging when used in combination with other sun protection measures.

Water-resistant sunscreen: Sunscreens can not be labeled as “waterproof” or “sweat-resistant” as these terms may be misleading. Sunscreens may claim to be “waterproof,” but must test based on testing to protect the skin from swimming or sweating for 40 or 80 minutes.

Expiration date: Check the expiry date of the sunscreen to ensure that it is still effective. Most sunscreen products are stable for at least 2 to 3 years. However, you may need to shake the bottle to remix the sunscreen ingredients. Sunscreens which have been exposed to heat for a prolonged period of time, e.g. B. if they have been stored in a glove box or trunk over the summer, may be less effective.

Be sure to apply the sunscreen properly
Always follow the instructions on the label. Most experts recommend generously applying sunscreen. When donning, pay special attention to the face, ears, neck, arms, and any other areas not covered by clothing. And do not forget your lips. Lip balm with sunscreen is also available. If you are wearing insect repellent or make-up, first apply the sunscreen.

Ideally, about 1 ounce of sunscreen (such as a shot glass or palm) should be used to cover the arms, legs, neck, and face of an average adult. Sunscreen must be reapplied at least every 2 hours to maintain protection. Sunscreens can be washed off if you sweat or swim and then wipe off with a towel, so they may need to be reapplied more often.

Some people may not think that if they use sunscreen with a very high sun protection factor, they do not have to be as careful as they use it, but that’s not true. If you are using sunscreen with a very high sun protection factor, keep in mind that this does not mean you can stay in the sun longer, use less sunscreen, or use it less often. Always read the label.

Some sunscreen products can irritate your skin. Many products claim to be hypoallergenic or dermatologically tested, but the only way to be sure that a product will irritate your skin is to try it out. A common recommendation is to apply a small amount every day for 3 days to the soft skin on the inside of your elbow. If your skin does not turn red



Most skin cancers are caused by excessive UV radiation. Most of this exposure comes from the sun, but some can come from artificial sources, such as As solariums and sun lamps. People who are exposed to UV rays are at higher risk for skin cancer.

The main types of UV rays that can affect your skin are UVA rays and UVB rays. UVB rays can damage the skin and cause skin cancer. There are no safe UV rays.

What influences the UV exposure?

The strength of the sun’s UV rays reaching the ground depends on a number of factors, including:

Time of day: UV rays are strongest in the middle of the day between 10 and 16 o’clock.
Season: In spring and summer the UV rays are stronger. This is less of a factor near the equator.
Distance from the equator (latitude): The UV exposure decreases as you move away from the equator.
Height: At higher altitudes, more UV rays reach the ground.
Cloud cover: The effect of clouds may vary, but it is important to know that UV rays can reach the ground on a cloudy day.
Reflection of Surfaces: UV rays may be reflected off surfaces such as water, sand, snow, or pavement, resulting in increased UV exposure.
The UV index
The US Weather Service and the Environmental Protection Agency (EPA) have developed the UV Index, which gives you an idea of ​​how close the UV light is to a particular day in your area, on a scale of 1 to 11+. A higher number means a higher risk of exposure to UV rays and a higher risk of sunburn and skin damage, which can eventually lead to skin cancer. The UV index is part of many weather forecasts across the country. For more information on the UV Index and your local UV index forecast, visit the EPO website at

Other factors that influence UV exposure

Along with the intensity of the rays, the amount of UV exposure also depends on how long your skin is exposed and whether your skin is protected with clothing or sunscreen.

People living in areas with bright sunlight all year round are at a higher risk for skin cancer. If you spend a lot of time outdoors to work or recover without protective clothing and sunscreen, your risk increases.

The exposure pattern can also affect your skin cancer risk. For example, a common childhood sunburn may increase the risk of some types of skin cancer many years or even decades later.

It is also important to understand that some people are more likely to suffer skin damage from the sun for a variety of reasons.
