5,“I drink caffeine to stay awake. It has positive effects on me. I’m healthy, and there’s nothing wrong with me,”said Sarah Green, a freshman, who consumes many caffeine drinks to stay awake in completing the many tasks in her busy schedule.
Caffeine is known to have many positive and negative consequences, and now there might be an additional positive effect may have been discovered. A study suggests that a skin lotion(洗液) containing caffeine, which is also found in green tea, may reduce the risk
of skin cancer. Two lotion tests were conducted on hairless mice that were exposed to high levels of ultraviolet radiation (紫外线). As a result, the lotion reduced the number of tumors (肿瘤) each mouse developed.
Unlike sunscreen (遮光剂), the new lotion is applied after exposure to the ultraviolet rays. Rays from the sun can cause genetic changes in the skin that can lead to skin cancer. Caffeine obstructs this action and causes the diseased cells to kill themselves.
“I know that caffeine has been found in certain drinks and it causes increased activity of the nervous system, and increased blood pressure on blood vessels (血管). I don’t know of any positive effects of caffeine,”health teacher Montego Estes said. Caffeine, found commonly in tea, coffee and soft drinks, provides people with an increase in energy. Half of all American adults consume more than 300 milligrams of caffeine per day. Caffeine is addictive because it uses the same mechanisms as amphetamines, and cocaine and heroine to ex cite the brain.
“This new cream doesn’t sound to me as though it would work,”junior David Bobbit said, “Caffeine seems to have more negative effects than positive ones.”
Skin cancer is the most common of all cancers in the US. About one million cases will be diagnosed in the country this year. There will be more than 88,000 new cases of melanoma, the disease’s
deadliest form of skin cancer.
