W: Good morning, class. Today I thought we would talk about something bright and cheerful—the sun. Can anyone tell me how you feel when it’s sunny compared to how you feel when it’s cloudy?
M: I find that it’s a lot easier to get up in the morning if it’s sunny.
W: Well, what if I told you that it would rain for weeks on end with no break.
M: I don’t think I would like that very much.
W: Most of the articles we read lately regarding the sun are discussing the negative effects of staying in the sun for too long, saying that [1] ultraviolet radiation from the sun is a major cause of skin cancer. [2] Although these articles are factual, the sun does have some positive side effects as well. As a matter of fact some scientists believe sunlight may reduce the risk of several types of cancer.
M: Excuse me, but many articles that I’ve read state that it can take as little as 30 minutes to get a sun burn.
W: True, but in small doses, the sun can be quite healthy for you. In fact, recent studies have found that [3] sunlight can actually help protect you from certain types of cancer such as breast and stomach. More importantly, [4-1] the sun also provides us with our main source of vitamin D.
M: Well, I don’t need to worry about vitamins because I take multi-vitamins every day.
W: That’s great, but wouldn’t it be better if you didn’t have to take them and you were able to get vitamins in a more natural way such as food and the sun?
M: Does that mean we should spend all day in the sun without any protection?
W: No, [4-2] spending roughly ten minutes per day in the sun should be enough to supply us with all the vitamin D that we need.
