자외선 차단은 안전한 공기와 빛 주변 환경 유지를 위해 매우 중요합니다.
The Importance of Sunscreen Protection
With the sun always out and the daylight hours increasing, it is important to protect yourself from its ultraviolet (UV) rays whatever the season. Sunscreen is one of the most important things you can do to protect yourself from the sun’s harmful UV rays and the damage they can cause. Sunscreen provides the defense you need to avoid UV damage from both UVA and UVB rays. But many people are still unaware of how essential sunscreen is for protection against sunburn, premature aging and skin cancer. So, just why is sunscreen so important? Let us find out…
What is Sunscreen?
Sunscreen is a lotion, spray, gel or other topical product that absorbs or reflects some of the sun’s ultraviolet (UV) radiation and thus, helps protect against sunburn. Sunscreen works by either chemically absorbing, scattering or reflecting some of the sun’s UV radiation. Generally, sunscreens contain one or more of the following ingredients: organic compounds, zinc oxide, titanium dioxide, and avobenzone.
What is UVA and UVB Rays?
UV radiation consists of three different types of rays: UVA, UVB and UVC. UVA is the longest and the weakest type of radiation and is able to penetrate into the deepest layers of the skin. It is responsible for most of the skin damage that we experience and is associated with wrinkling and skin aging. UVB is the stronger and warmer form of UV radiation and is the type of radiation that causes sunburn. UVC is the shortest form of UV radiation and is the most harmful. Fortunately, the majority of UVC radiation is filtered out by the ozone layer.
What are the Benefits of Sunscreen?
The benefits of using sunscreen are two-fold. Firstly, sunscreen helps to protect against sunburn and skin cancer. Sunburns damage skin cells and increases the risk of skin cancer. Additionally, sunscreen provides protection from other signs of sun damage such as wrinkles, dark spots, and premature aging. Evidence also shows that sunscreen can help to prevent cataracts and other vision problems, particularly when applied in combination with sunglasses or other forms of eye protection. Finally, sunscreen helps to prevent sunburns, which can in turn reduce the amount of time spent in the sun and thus diminish overall exposure to UV radiation.
How to Choose Sunscreen?
When choosing a sunscreen, it is important to ensure that it provides protection against UVA and UVB rays. To do this, look for a broad-spectrum sunscreen with an SPF of at least 15. Higher SPF products will provide more protection, but you should always reapply frequently and as recommended on the product label. Water resistant sunscreens are also helpful, especially if you are swimming or playing sports.
Conclusion
Sunscreen is one of the most important things you can do to protect yourself from the sun’s harmful UV rays. It helps to protect against sunburn, premature aging, and skin cancer. To make sure you are getting the best protection, choose a broad-spectrum sunscreen with an SPF of at least 15 and reapply every two hours. So don’t forget to grab your sunscreen whenever you head outdoors!
