In fact, systolic blood pressure goes down.

事实上，收缩压会下降。

Why systolic blood pressure? Why am I mentioning that?

为什么是收缩压？我为什么要提这个？

This is your systolic blood pressure.

这就是你的收缩压。

When we're gearing up to do something hard, systolic blood pressure goes up in anticipation of the performance.

当我们准备做一些困难的事情时，收缩压会因为预期的表现而升高。

Elevated systolic blood pressure is considered between 120 and 129 mmHg and less than 80 mmHg on the diastolic side.

收缩期血压升高应该在120到129mmHg之间，舒张期血压则是应该在小于80mmHg的区间内。

In severe preeclampsia, systolic blood pressure can be 160 mmHg or greater and diastolic blood pressure can be 110 mmHg or greater.

重度子痫前期患者的收缩压可达到160毫米汞柱以上，舒张压达到110毫米汞柱以上。

Now, 'normal' systolic blood pressure is defined as less than 120 mmHg, and a normal diastolic pressure is less than 80 mmHg.

现在，正常的收缩期血压被定义在120mmHg以下，正常的收缩压则是应该小于80mmHg。

Her systolic blood pressure would rise.

她的收缩压会上升。

When diagnosing preeclampsia, hypertension is defined as a systolic blood pressure of 140 mmHg or greater or diastolic blood pressure of 90 mmHg or greater.

在诊断子痫前期时，高血压的定义为收缩压大于等于140毫米汞柱或舒张压大于等于90毫米汞柱。

The first number is your systolic blood pressure — essentially the peak pressure, produced by the contracting ventricles that push blood out to all of your tissues.

第一个数字是你的收缩压——也就是峰值压力，由收缩的心室产生，将血液推出到你所有的组织。

So if your systolic blood pressure is too low, that could mean that, say, the volume of your blood is too low — like, maybe because you've lost a lot of blood, or you're dehydrated.

所以如果你的收缩压过低，这可能意味着，比如说，你的血容量过低——比如，可能是因为你失血过多，或者脱水了。

STEP 3 Put some plants on your desk. One study found that when workers had greenery nearby, they were 12 percent quicker at a given computer task and their systolic blood pressure lowered by one to four points.

办公桌上放置一些植物。一项调查发现，当工作人员附近有绿色植物时，他们在特定的计算机任务中效率高12%，他们的心脏血压会降低1至4个点。
