滴答滴!了解你的生理时钟
PART
3
Take(1)
blood pressure(2) for example. With monitors(3), chronobiologists(4)
can measure(5) a person’s pressure several times over a 24 hour
period. Here’s what they’ve found: In the evening, blood pressure,
on average(6), starts to decrease(7). But in the morning, when we
get up, there is a huge(8) surge(9) in blood pressure as adrenalin(10)-like
chemicals(11) are released(12) and the heart rate(13) rises, preparing
the body for the new day. Smolensky says that can be a problem for
patients on blood-pressure medications(14), which remain(15) fairly(16)
constant(17) in the bloodstream(18) all day. So now some pharmaceutical(19)
companies are making blood pressure drugs that are time-specific(20).

以血压为例子,时间生物学家使用监视器在24小时内为病人量数次血压,以下是他们的发现: 一般来说,血压在晚上开始下降,但是在早上,当我们起床的时候,体内释放一种类似肾上腺素的化学成分,导致血压大幅上升,心跳加快,让身体准备迎接新的一天。
斯莫伦斯基说,这个发现可能为接受血压药物治疗的病患引发一个问题,过去药物在血管中的剂量一整天都维持不变,因此现在,部分制药厂开始制造特定时间的血压药物。
So,
how well do you think you know your own “body clock”? We’ve put
together(1) a quiz(2) to test your knowledge. With the right(3)
information, chronobiologists say you can even predict when a fatal(4)
heart-attack(5) may happen. Which brings us to question number one:
what time of day do most heart attacks occur(6)? a) morning b)
afternoon c) just after work d) just before retiring(7) for
the night The answer is - the morning. Because blood pressure rises
in the morning, hearts that are vulnerable(8) to breakdown(9) -
producing heart attack.

你对自己的「生理时钟」了解多少?我们提供了测验,来测试你的知识。时间生物学家根据正确的知识表示,你甚至可以预测致命的心脏病发作的时间,这就是第一个问题,多数心脏病于何时发作?
a) 早上 b) 下午 c) 下班后 d) 晚上睡觉前 答案是早上,因为血压在早上上升,此时心脏最为脆弱,容易导致心脏病发作。
