A. That depends on what is meant by oversleeping, said Dr. Charles P. Pollak, director of the Center for Sleep Medicine at NewYork-Presbyterian Hospital/Weill Cornell Medical Center. A long period of sleep may be just what the doctor ordered.
“People do not necessarily sleep a long time arbitrarily,” Dr. Pollak said. “Sometimes it is in response to insufficient sleep. People make up for lost sleep on the weekend, and the sleep may be very long. But that is not the same as oversleeping. It does not contribute to feeling groggy and tired, but helps make up for sleep you should have been getting during the week.”
Dr. Pollak explains that most people cannot sleep more than the amount they need, which varies a great deal from person to person and from age to age.
“Extending sleep beyond what is normally required might sometimes make you feel groggy,” he said, “but it is not easy to do.”
“There is such a thing as being sleep-deprived,” he continued. “But as far as we know, there is no such thing as being wake-deprived. If you awake feeling refreshed, that is how much sleep you actually require.”

纽约长老会医院/ Weill Cornell 医学中心，睡眠医学中心主任Charles P. Pollak博士称，这取决于如何定义睡眠过度。长时间睡眠可能只是医生的一种说法。
“People do not necessarily sleep a long time arbitrarily,” Dr. Pollak said. “Sometimes it is in response to insufficient sleep. People make up for lost sleep on the weekend, and the sleep may be very long. But that is not the same as oversleeping. It does not contribute to feeling groggy and tired, but helps make up for sleep you should have been getting during the week.”
“人们没有必要随意延长睡眠，”Pollak博士说。“有时候（延长睡眠时间）是因为睡眠不足。人们会在周末补充睡眠，所以可能睡的久一些。但这并非睡眠过度。它不会导致乏力和疲倦，只是帮你补充一周本该获得的睡眠。”
Dr. Pollak explains that most people cannot sleep more than the amount they need, which varies a great deal from person to person and from age to age.
Pollak博士解释说，大部分人不会睡眠过度，而睡眠需要量因人而异，且随年龄变化。
“Extending sleep beyond what is normally required might sometimes make you feel groggy,” he said, “but it is not easy to do.”
“睡眠时间超过正常需要量有时可能会令人乏力，”他说，“但这种情况很难出现。”
“There is such a thing as being sleep-deprived,” he continued. “But as far as we know, there is no such thing as being wake-deprived. If you awake feeling refreshed, that is how much sleep you actually require.”
“有一种情况是睡眠不足，”他继续说。“但据我们了解，并没有睡眠过度（wake-deprived）这种事儿。如果当你醒来时感觉精力充沛，那这样的睡眠时间就是你真正需要的。”
