Introduction

Is Sunbathing Good for You?

The ultraviolet radiation (UV) in sunlight can cause skin cancer. there are many factors that can effect the risk involved when you sunbathe.

Your skin tone can effect the damage caused by UV radiation because the brown pigment in skin, menalin, provides some protection. The darker your skin the more protected you are from the damaging effects of sunlight. If you have particularly fair skin, you should take extra care when sunbathing; use a suncream with a high SPF and don't stay out in the sun for prolonged lenghts of time. The amount of time you can spend in the sun varies from person to person but if you know you are proned to burning or if you have a family history of skin cancer you, too, should take extra precautions. People who have had excessive exposure to UV radiation from the sun without protection are at a greater risk from skin cancer as this is the most common cause of skin cancer.

Middle

experts recommend that you do not stay in the sun around midday. this is because this is when the suns UV rays are at their strongest and therefore we are at the most risk.

sunbathing also has its good points. it activates a gene called pom-C which inturn helps to: create menalin that determines your skin clour, enhance your sex drive, stimulate your happiness hormones (endorphins) and help you to burn fat by stimulating leptin.

in reasonable doses, sunbathing helps your body to genertate essential lots of vitamins, primarily vitamin D which strengthens your bones and muscles and it also boosts the immune system which protects you from infections.

Sunlight can also help your body combat various illnesses including cancers and it can help clear up some skin problems. Being in the sun releases endorphins which act to reduce your stress levels through inducing a sence of relaxation and wellbeing.

Conclusion

in conclusion I think moderation is key. It is up to you to decide what is right for you. get it right and you will feel and be healthy and look great. But if you get it wrong the penalty could be very severe. on one hand there is a danger of skin cancer but on the other hand you could end up with vitamin deficiencies. There is always more advances in scientific knowledge and there will always be conflicting views. i think it is up to you how you iterpret the evidence- what is right for one person may not be for another. there is risk involved with every aspect of our lives and nothing can ever be completely safe.

Here's what a teacher thought of this essay

3 star(s)

Overall a good essay with some decent points made on both sides of the argument though at times the writer is quite vague with their explanations.
The conclusion would be helped by drawing directly from the main body of the text and some re-ordering of the middle paragraphs would help.
As stated at the beginning there are many spelling and grammatical errors that are readily fixable with a spell check and a proof read. This will make the essay as a whole read much better.

  1. Mutagenesis: The Effect of Radiation on Radish Seeds.

    Upon contact with cellular macromolecules, the high-energy waves of radiation have the ability to damage the molecular structure of the atoms contained in the macromolecules. The phenotype of an organism is coded for by the organisms cellular DNA; therefore, damage to DNA due to radiation may result in genetic mutations which may exhibit phenotypic change (Baumstark).

    What we don't know about these effects is that Teenagers are most affected. The researchers pointed out that 12-26 week old rats are comparable in age to human teenagers, the most frequent users of mobile phones. This level of damage to the nerve cells is worrying, as "it may result in reduced brain reserve capacity".

    He began working with Hans Geiger in the University of Manchester; they observed shooting a narrow beam of alpha particles (nucleus of a helium atom) onto a thin gold foil. * Rutherford was amazed that some alpha particles diverted at dramatic angles instead of continuing through the thin metal foil, they seemed to 'bounce back.'

    Rocking happens when the two atoms moved in the same direction, while scissoring happens when the two atoms rock, move towards and away from each other. Out-of-plane bending happens when the two atoms move out of the same plane as the third atom.

    Cancer can also be caused by cell structure alternation, alternatively known as mutation. Other problems associated with microwave radiation include; fatigues, headaches, learning problems, sleep disorders (insomnia) and memory loss.
