CHAPTER 5:
HOW TO SUNBATHE SAFELY, ALL YEAR ROUND
What we are told now told about sunbathing is very different from what was being recommended fifty years ago. This chapter puts together information from the past and current research to show you how to sunbathe in safety. In order to do this you need to develop an understanding of the variables affecting sunbathing, i.e., latitude, altitude, the effects of choosing different times of day and different times of year, of being in different ambient temperatures while sunbathing. You also need to know: how sunlight gets to us via the Earth's atmosphere clouds and air pollution; what happens when it passes through glass and clothing; how different reflecting surfaces affects the intensity of the sun's rays. Diet is another very important factor as the proportion of fat in your diet, and its mineral and vitamin content affects the way your skin responds to sunlight. Chapter 6:
