Sunscreen And UV Rays – How To Protect Against Skin Cancer
Skin Cancer is a common disease that is thought to develop when the skin is exposed to ultraviolet rays. Depending on the type of skin, this exposure can be limited and still lead to the development of some form of skin cancer. Fair skin that burns easily in the Sun is particularly vulnerable. As the Sun is the leading source of Ultraviolet (UV) radiation that people are regularly exposed to it is important to protect yourself when in the Sun. This article will list the common methods that can help prevent skin cancer. It will concentrate on Sunscreen and how it works to protect your skin.
Before covering how sunscreen works, it should be reiterated that sunscreen is not the only way to protect your skin from the sun. It should be used in conjunction with some of the ideas covered below.
Avoiding over exposure to UV rays is done by avoiding exposure to the Sun. The worst time to be in the sun is around midday when it is high in the sky. A few hours either side of this time are also bad. Try to avoid being in the Sun around this time. If you are in the Sun around this time, or any time for that matter, take precautions.
Wear clothing that can protect your skin form sunlight. Darker colored clothing works better than lighter colors. cover your arms and legs if practical or comfortable.
Wear a hat with a wide brim. You could also use a sun umbrella if you don’t like hats but a hat is the best method of protecting the scalp and face.
Wear a good pair of sunglasses, as skin cancer can also affect the eyes.
After taking all these precautions you should then apply sunscreen. Cover parts of your body that are not protected by clothing and come into direct contact with the sunlight.
Sunscreens come in two types. The more common type is a chemical sunscreen that absorbs UV rays. The other type is a physical sunscreen that reflects or blocks the UV rays (these are sometimes called sunblocks).
Sunscreen is often given a Sun Protection Factor (SPF). This indicates how effective the sunscreen is against UVB radiation. UVB radiation is thought to be the worst form of UV rays for skin. Most advice suggests a sunscreen with SPF of 30+ is the minimum that you should go for. However, SPF does not cover how the sunscreen works for UVA radiation. If you want a sunscreen that protects against UVB and UVA radiation then look for a broad spectrum sunscreen.
Sunscreens that act as a sunblock are best if you have to spend plenty of time out in the Sun. No doubt you have seen people wearing such creams on the nose or lips. It is almost like a paint that they have applied to the skin. This puts many people off using such creams but they are the best way to protect your skin from the Sun.
Sunblock sunscreen will have either titanium dioxide or zinc oxide in them (they are also sometimes referred to as zinc cream). If you don’t appreciate having a large band of zinc cream across your nose then an alternative is ultramicronized titanium or zinc sunscreens. They are transparent but do the same job of reflecting UV rays.
Regardless of the type of sunscreen you go for, remember to always reapply it every 2 hours. This may vary depending on how active you are in the Sun. Get a cream that you like in terms of texture or fragrance so that the reapplication is not such a chore.
