Summer is the time to go to the beach and enjoy the great outdoors. We need to be careful in getting too much exposure to the sun which can lead to painful consequences. Skin cancer is a result of overexposure to UV rays. We try to find out the relationship between skin cancer and sunlight.
It is proven that too much UV radiation from the sun or sunbeds is the leading cause of skin cancer. There are ways to prevent skin cancer by using safety measures when exposed to the sun and avoiding sunbeds.
There are two types of UV rays that damage our skin. Both of these rays can cause skin cancer.
UVB is responsible for most of sunburns while UVA is able to penetrate deep into our skin which causes skin aging.
The third type of UV ray is the most dangerous of them all called UVC. Fortunately, this ray is blocked entirely by the ozone layer and doesn’t reach the surface of the earth.
Sunburn is a clear indication that the DNA in your skin cells has been damaged by exposure to UV radiation. This means that you have stayed under the sun for too long. If you get a sunburn even once every two years can triple your risk of skin cancer.
We think of sunburn as painful, peeling and blistering. This is not always the case, as long as your skin has turned pink or red under the sun, it’s sunburnt. It is more difficult to notice for people with darker skin; they may feel irritation, tenderness or itchiness.
UV rays can’t be felt, the heat from the sun comes from infrared rays which can’t burn you. This means that you can still get burnt on cold days.
Being exposed to too much UV radiation from the sun or sunbeds can damage the genetic material in your skin cells. If DNA damage builds up over time, cancer can develop.
Our bodies have ways of repairing most of the damage, but damaged DNA can be left behind. The painful symptoms of sunburn is a signal that your body is trying to repair the damage in your DNA skin cells.
Getting a sunburn does not mean that you will develop cancer automatically. Due diligence should be practiced by protecting your skin from further damage.
Cancer is caused by the accumulation of damage which is why prevention is essential.
If you notice your skin turning red or pink, you should come out of the sun and cover up so that no further damage can occur. Putting on more sunscreen won’t help and will not let you stay long safely under the sun.
Sunblock lotion can help your skin feel better by treating the symptoms of sunburn, but it can’t repair DNA.
Skin cancers can be invasive. Tumors can spread through the layers of the skin and spread to other parts of the body.
Skin cancer can be treated successfully when diagnosed in its early stages.
The best way to protect our skin from UV includes using shade and clothing as the first line of defense. Put sunscreen on body parts that are not covered by shade or apparel.
Umbrellas may offer some protection from UV but not completely protect you. They can only filter and not block UV rays.
Clothes, sunglasses, and hats are effective in UV protection. Use clothes that are long sleeved, loose fitting and deeper in color. It is also better to choose clothing that is made of polyester, wool, silk or nylon.
Wide-brimmed hats protect from UV while caps cover the nose and forehead leaving other parts of the face exposed.
Sunglasses can protect our eyes from UV exposure. Look for sunglasses that block 100% UVA and UVB rays.
