But today, almost 50% of people get 6 hrs or less each night.

然而现在，几乎 50% 的人每晚睡 6 小时或更少。

Not so surprisingly, those who get 8 hrs of sleep over a 2 weeks period, show very few lapses in attention and no cognitive decline.

毫不奇怪，那些在两周内睡了 8 小时的人，注意力更集中，认知能力也没有下降。

When looking at the results deeper, scientists concluded that getting 6 hrs of sleep for 10 days in a row was the same as not sleeping for 24 hrs straight.

当深入研究结果时，科学家得出结论，连续 10 天睡 6 小时和连续 24 小时不睡觉是一样的。

But your brain slowly begins to shut off the areas associated with planning and making decisions, and, even though you may still feel fine getting 6 hrs, the truth is actually much darker and worrisome that you might realize.

但是你的大脑慢慢地开始关闭与计划和决策相关的区域，即使你可能仍然觉得睡6个小时也没什么问题，事实上比你意识到的可能还要糟糕和令人担忧得多。
