Introduction

How safe are sun beds? UV light is radiation that can't be seen and is beyond the violet end of the visible spectrum making UV an ionizing radiation. Ionizing radiation is high in energy and can damage living cells, causing skin cancers and diseases. The sun... The sun is the source of energy that all life on earth depends on, without the sun the earth would be unable to survive. The sun radiates elector-magnetic vibrations with different wave lengths. Wave lengths of heat rays are longer than the wave lengths for visible light. Ultraviolet radiation which tans our skin has even shorter than these. The sun can be good for you because; * Ultraviolet (UV) radiation from the sun is our main source of vitamin D, important for your bones, muscles and immune system * Vitamin D may also have the ability to combat the development and spread of cancerous tumours * Sunlight stimulates the pineal gland in the brain. This produces certain chemicals called 'tryptamines' which improve our mood The sun can be bad for you because; * Exposure to solar and artificial UV radiation is widely recognized as a leading and preventable cause of skin cancer * Exposure to high levels of sunlight makes you four times more likely to develop cataracts in your eyes * Sunburn can change the distribution and function of disease-fighting white blood cells and damage our DNA (Information from http://www.bbc.co.uk/science/hottopics/sunshine/index.shtml) ...read more.

Conclusion

At most, a sunbed tan is equivalent to a factor 4 sunscreen. Not enough to keep you safe in the sun. "Being tanned is a sign of health" - False The simple fact that your skin has changed colour is a sign that it has been damaged. Using sunbeds before the age of 35 increases your risk of developing skin cancer by up to 75%. UV from sunbeds not only harms your skin, if you don't wear goggles it can also damage your eyes. UV eye damage can lead to irritation, conjunctivitis and even eye cancer. After myth from a different site says: "Getting a tan helps to clear up skin" - False Even though a tan may temporarily cover the redness of acne, there's no evidence that having tanned skin helps to clear up acne. People who tan in the sun or in tanning booths or beds run the risk of developing dry, irritated, or even burned skin. They're also at increased risk of premature aging and developing skin cancer. From this section we find that people don't really know a lot about sun beds and the effects they have on the human body. So should more be done to help people find out what effect sun beds really have?
