從小我們就被教育坐姿要端正，避免含胸駝背的懶散坐姿，但事實上，喜歡懶散坐姿的人還真不少。好消息是，近日根據The Conversation網站的報道，大量研究表明，坐姿懶散不會對脊柱造成損傷，只不過會影響記憶力和心情。

Slouching is traditionally considered to be a “bad” posture — with some claiming it will damage your spine and cause pain.
懶散的坐姿在傳統上被視為一種“不良”坐姿，有些人還聲稱坐姿懶散會對脊柱造成損傷，導致脊柱疼痛。

The great news is that in the past two decades, there’s been a plethora of rigorous clinical studies conducted which have concluded that there’s no relationship between slouching and spinal pain. There’s also no evidence that people who slouch are more likely to suffer with back or neck pain compared to non-slouchers.
好消息是，過去二十年來，大量嚴謹的臨床研究得出結論稱，坐姿懶散和脊柱疼痛之間沒有關系。沒有證據證明，坐姿懶散的人相比坐姿不懶散的人更容易背痛、脖子痛。

There’s also no clear evidence that slouching while sitting at your desk or while using your phone causes damage to the spine. Even the UK government’s latest guidance on working with screens puts less emphasis on an idealised posture at the workstation.
也沒有明確的證據表明，辦公或看手機時坐姿懶散會對脊柱造成損傷。就連英國政府對于坐在屏幕前工作的最新指導意見也不再強調理想的辦公坐姿。

Instead, they emphasise the importance of adopting comfortable positions, varying your positions, avoiding awkward positions (such as flexing or arching your back or neck) and including regular breaks from your static posture throughout the day. All of these tips will help reduce the risk of developing pain and muscle fatigue.
相反，這一指導意見強調，要采用舒適的坐姿，不時地變換姿勢，避免不自然的坐姿（比如彎曲或拱起背部或頸部），并在一天當中定期活動一下，不要長時間保持靜態坐姿不動。所有這些建議都有助于減少身體疼痛和肌肉疲勞的風險。

There’s a pretty good reason why slouching doesn’t damage our spines, and that is because our spines are designed to allow movements as diverse as Olympic weightlifting to limbo dancing.
有一個很好的理由可以解釋為什么坐姿懶散不會損傷脊柱，那就是人體脊柱可以承受從奧運會舉重到林波舞等各種強度和形式的運動。

But there is one area where slouching may have a negative effect. Slouching has been linked to poorer information and memory recall, as well as worse mood when compared to sitting upright. These memory and mood problems are shown to be rapidly improved when moving from a slouched to erect posture.
但是坐姿懶散也許會對一個方面產生負面影響。與坐姿端正相比，坐姿懶散被認為會影響信息回憶能力和記憶力，并會讓心情更糟糕。當人們從懶散坐姿切換成端正坐姿時，記憶問題和情緒問題都迅速改善。

So if you’re a sloucher, rest assured that it isn’t really bad for you and is as good as any other posture you adopt. Comfortable postures are safe and sitting is not dangerous.
因此，如果你是個坐姿懶散的人，你可以放心的是，你的坐姿不會對你產生什么實質性的有害影響，也不比其他坐姿差。舒適的坐姿是安全的，坐著也不危險。

Overall, the human spine is designed to be on the move rather than static in one posture for long periods, which is why movement and changing your posture throughout the day is important to reduce fatigue and subsequent discomfort.
總體而言，人類脊柱就是為了活動而設計的，而不是為了長時間保持一個靜態姿勢。這就是為什么在一天當中不時活動一下變換姿勢對于減少疲勞和（久坐帶來的）不適很重要。
