Part of what keeps your heart under control is your parasympathetic nervous system.

保证心脏处于可控状态的部分原因是你的副交感神经系统。

If the heat generated is intense enough, the body's parasympathetic nervous system is triggered, which creates a relaxation response.

我们有副交感神经系统和交感神经系统。

Then, the prefrontal cortex takes over from the amygdala and stimulates the parasympathetic nervous system.

然后，前额叶皮层接管杏仁核并刺激副交感神经系统。

We also see that the parasympathetic nervous system decreases heart rate, which decreases cardiac output.

我们还看到副交感神经系统降低了心率，从而降低了心输出量。

Some drugs, like ones for overactive bladders or excessive sweating, target the entire parasympathetic nervous system.

有些药物，例如治疗膀胱过度活动症或过度出汗的药物， 会针对整个副交感神经系统。

We also learned that the parasympathetic nervous system can decrease the heart rate.

我们还了解到，副交感神经系统可以降低心率。

It stimulates your parasympathetic nervous system, the half of your nervous system responsible for activities like resting and digesting.

它会刺激您的副交感神经系统，这是负责休息和消化等活动的神经系统的一半。

In the opposite way, the parasympathetic nervous system can decrease the heart rate, which decreases the cardiac output.

副交感神经系统以相反的方式，可以降低心率，从而降低心输出量。

To recover from a threat, our parasympathetic nervous system can put our body into a rest-and-digest state allowing us to relax and be calm.

为了从威胁中恢复过来， 我们的副交感神经系统可以让我们的身体进入休息和消化状态， 让我们放松和平静。

When this alarm sounds, the hypothalamic, pituitary, and adrenal systems, known as the HPA axis, work together to send signals to the parasympathetic nervous system.

当此警报响起时，称为 HPA 轴的下丘脑、垂体和肾上腺系统会协同工作，向副交感神经系统发送信号。

In contrast, the parasympathetic nervous system is more our rest and digest, or feed and breed functioning, and this is where digestion becomes a priority as well as reproduction.

相比之下，副交感神经系统更多的是我们的休息和消化，或者喂养和繁殖功能，这就是消化和繁殖成为优先事项的地方。

Mainly that it consists of two primary, complementary divisions, the sympathetic nervous system, which arouses your body, and the parasympathetic nervous system, which is charge of resting, digesting, and repair.

主要由两个主要的互补部门组成，交感神经系统，唤醒你的身体，副交感神经系统，负责休息、消化和修复。

That’s the parasympathetic nervous system at work — the part responsible for involuntary processes that are more about resting, like digestion and lowering your heart rate.

这就是工作中的副交感神经系统——负责更多与休息有关的非自愿过程，如消化和降低心率。

This can be one of the most immediate ways to calm anxiety, because deep breath directly activatesthe natural de-stressing part of our nervous systemscalled the parasympathetic nervous system.

这可能是平息焦虑最直接的方法之一，因为深呼吸会直接激活我们神经系统的自然减压部分， 称为副交感神经系统。

After high stress situations (ie: fighting for your life) the parasympathetic nervous system has a backlash reaction that balances out the reaction of the sympathetic nervous system.

在高压力的情况下(例如：为你的生命而战)副交感神经系统有一个对抗性反应，以平衡交感神经系统的反应。
