1
Does stress make you more productive?
2
Yes and no. Adrenaline makes your heartbeat and breathing faster, while cortisol makes you more alert.
3
A little short-term stress can help you crunch through repetitive tasks, but for difficult ones, stress can work against you
4
because cortisol forces your body to prioritize your muscles and impulses over problem solving.
5
Over time, high levels of cortisol can leave your memory and decision-making weaker.
6
Being on high alert requires energy and you soon need to refuel.
7
As cortisol also affects hormones that make you feel full, you'll likely crave fatty and sugary foods.
8
At first, you may feel less stressed as eating meets your fuel demands and may even lower your cortisol levels.
9
But this can become a doom loop, eat more junk food or feel stressed.
10
Tweaking your diet can help.
11
Omega-3s found in fatty fish can make you less reactive to stress, while flavonoids in dark chocolate can boost your cell's defenses.
12
But the best way out of the cycle is sleep.
13
Your natural lowest levels of cortisol are around midnight when your stress response system resets.
14
Getting enough sleep also makes you more resilient to stress-related diseases.
15
So before stress becomes a deadly poison, get some rest.

什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
