Surfing the web and texting before bed

在睡觉前上网和发短信

Using certain forms of technology right before bedcan stress you out.

在睡前使用某种形式的技术可以增加压力。

One study showed that people who texted and surfed within two hours of going to bed had greater stress levels than those who didn't, says Live Science.

一项研究表明,那些发短信和上网两小时内睡觉比那些没有这样做的有更大的压力,《生活科学》说。

However, not all forms of technology engagement increases stress. Watching TV and responding to emails apparently don't have an adverse effect.

然而,并不是所有形式的技术接触都会增加压力。看电视和回复邮件显然没有不利影响。
