Getting enough sleep on a regular basis is one important way to protect the health of your heart. Poor sleep is associated with a range of cardiovascular(心血管的) problems, including high blood pressure, heart attack, and heart failure. Both men and women are at increased risk for these conditions. But we continue to learn that when it comes to health problems associated with sleep, the particular risks to men and women are not always the same. A new study suggests that for women who already have heart disease, poor sleep may be particularly dangerous to their heart health.
Research indicates that poor-quality sleep—and waking too early in particular—is associated with increased inflammation(炎症) among women with heart disease. There was no similar association found for men, suggesting that women with heart disease and sleep problems may be at particular risk for inflammation that can be damaging to the heart.
Researchers at the University of California, San Francisco investigated the relationship between sleep quality and inflammation linked to coronary(冠状的) heart disease. They also sought information about how an association between sleep and inflammation might differ between men and women. Their investigation included 980 men and women at first, and 626 completed the 5-year study. All of those included were suffering for coronary heart disease. The average age of men in the study was 66. Women were slightly younger, with an average age of 64. Researchers measured sleep quality by asking participants to rate their sleep over the previous month. They also asked for reports of some of the most common sleep problems, including difficulty falling asleep, difficulty staying asleep, waking frequently throughout the night, and waking too early in the morning.
After 5 years, researchers repeated tests for inflammation and once again sought reports on sleep quality and sleep problems. When they analyzed data for both men and women together, researchers found no links between inflammations and sleep quality. However, when they analyzed data taking gender(性别) into account, researchers found a relationship between inflammation and sleep existed for women, but not for men.

Here is an astonishing and significant fact: Mental work alone can’t make us tired. It sounds absurd. But years ago, scientists tried to find out how long the human brain could labor without reaching a stage of fatigue (tiredness). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day laborer, we would find it full of fatigue toxins (毒素) and fatigue products. But if we took blood from the brain of an Albert Einstein, it would show no fatigue toxins at the end of the day.
So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours of effort as at the beginning. The brain is totally tireless. So what makes us tired?
Some scientists declare that most of our fatigue comes from our mental and emotional attitudes. One of England’s most outstanding scientists, J.A. Hadfield, says, “The greater part of the fatigue from which we suffer is of mental origin. In fact, fatigue of purely physical origin is rare.” Dr. Brill, a famous American scientist, goes even further. He declares, “One hundred percent of the fatigue of sitting worker in good health is due to emotional problems.”
What kinds of emotions make sitting workers tired? Joy? Satisfaction? No! A feeling of being bored, anger, anxiety, tenseness, worry, a feeling of not being appreciated—those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.
1.What surprised the scientists a few years ago?
A. Fatigue toxins could hardly be found in a laborer’s blood.
B. Albert Einstein didn’t feel worn after a day’s work.
C. The brain could work for many hours without fatigue.
D. A mental worker’s blood was filled with fatigue toxins.
2.According to the author, which of the following can make sitting workers tired?
A. Challenging mental work.
B. Unpleasant emotions.
C. Endless tasks.
D. Physical labor.
3.What’s the author’s attitude towards the scientists’ idea?
A. He agrees with them.
B. He doubts them.
C. He argues against them.
D. He hesitates to accept them.
4.We can infer from the passage that in order to stay energetic, sitting workers need to ________.
A. have some good food
B. enjoy their work
C. exercise regularly
D. discover fatigue toxins
