Scientists in Norway have some good news for coffee drinkers. Researchers have already found evidence that the drink or the beans can help with weight loss, 1 one's risk of developing some diseases, promote muscle growth, protect against certain types of cancers and can even reduce one's risk of premature(早于预期的) death, among many other 2. Now it is said that a cup of 3 reduces physical pain.
The surprising finding is 4 a study involving 48 volunteers who agreed to spend 90 minutes performing computer tasks meant to finish office work. The tasks were known to 5 pain in the shoulders, neck, forearms and wrists. The researchers wanted to 6 how people with pain and those who were pain-free tolerated(忍受) the pain of such tasks. "As a matter of convenience, the scientists allowed people to drink coffee before taking the test to avoid 7 effects of caffeine lack, e. g. decreased vigor, sleepiness, and exhaustion, " they reported.
When it came time to analyze the data, the researchers from Norway's National Institute of Occupational Health and Oslo University Hospital noticed that the 19 people who drank coffee reported a 8 intensity(强度) of pain than the 29 people who didn't. In the shoulders and neck, 9, the average pain was rated 41 (on a 100-point scale) among the coffee drinkers and 55 for the non-coffee drinkers. Similar gaps were found for all pain sites measured, and coffee's obvious pain-reduction effect 10.
However, the authors of the study, which was published this week in the journal, BMC Research Notes, warn that the results of the study come with many 11. For starters, the researchers don't know how much coffee the coffee drinkers consumed(消耗) before taking the computer tests. 12, they doubt whether the coffee drinkers and non-coffee drinkers were 13 in all aspects except for their coffee consumption. Problems like these tend to 14 the importance of the findings. But those doubts are 15 to trouble the coffee drinkers looking for any reason not to cut back on their daily caffeine habit.
