究反复证实，社交媒体上的负面新闻看多了对人的精神健康有害无益。尽管如此，疫情期间想要“戒掉”社交媒体实在太难。怎样才能让自己开心地使用社交媒体？来看看科学家的解答。

Picture this: you're between Zoom meetings, and scrolling through your social media newsfeed. Headlines like "Death toll continues to rise", "COVID-19 may cause long-term health implications" and "Health-care systems overwhelmed" flash across your screen. Your mood takes a dive, but you can't stop scrolling.

想象一下这个画面：你刚开完一个视频会议，趁着空闲翻阅一下社交媒体推送的新闻。你的屏幕上闪过的标题都是“死亡率继续上升”、“新冠病毒可能会对健康产生长期危害”、“医疗系统不堪重负”之类的。你的心情骤然间变得低落，但是你仍忍不住翻阅的欲望。

If this scenario rings true for you, you're not alone. Research shows people have a tendency to seek out information during uncertain times – it's a natural coping mechanism. But is persistent information-seeking on social media, sometimes called doomscrolling, helpful during a pandemic, or any time?

如果这个场景曾发生在你身上，那么你不是孤身一人。研究发现，人们在充满不确定性的时期往往都会去寻找信息，这是本能的应对机制。但是在社交媒体上持续地搜寻信息（有时被称为末日刷刷刷）在疫情期间或其他时候真的有所助益吗？

Research on the effects of bad news on mood suggest exposure to negative COVID news is likely to be detrimental to our emotional wellbeing.

此前曾研究过负面新闻对心情的影响，结果表明，负面的疫情新闻不利于精神健康。

For instance, one study conducted in March 2020 involving more than 6,000 Americans found that the more time participants spent consuming COVID news in a day, the unhappier they felt.

举例而言，2020年3月开展的一项涵盖了6000多名美国人的研究发现，参与者在一天内用于浏览疫情新闻的时间越多，他们就越不开心。

These findings are striking but leave a few key questions unanswered. Does doomscrolling make people unhappy, or are unhappy people just more likely to doomscroll? How much time spent doomscrolling is a problem? And what would happen if, instead of doomscrolling, we were "kindness scrolling" – reading about humanity's positive responses to a global crisis?

这些研究结果令人震惊，但还是留下了几个悬而未决的关键问题。是末日刷刷刷让人不开心，还是不开心的人更爱末日刷刷刷？在末日刷刷刷上花多少时间会影响情绪？如果我们只看正面新闻（人们对全球危机的积极反应），不看负面新闻，会产生什么结果呢？

To find out, researchers conducted a study where they showed hundreds of people real-world content on either Twitter or YouTube for two to four minutes. The Twitter feeds and YouTube videos featured either general news about COVID, or news about kindness during COVID. Researchers then measured these participants' moods using a questionnaire, and compared their moods with participants who did not engage with any content at all.

为此研究人员开展了一项研究，让数百人花2到4分钟观看推特或油管上的真实内容。推特消息和油管视频中展示的是普通的新冠新闻或疫情期间的善举。然后研究人员用问卷测量了参与者的情绪，并将他们的情绪与没有看任何内容的参与者相比。
