把下面这篇文章的第三段翻译成中文：

“However, recent studies have shown that the amount of sleep a person needs can vary depending on their age, lifestyle, and overall health. For example, infants may need up to 17 hours of sleep per day, while teenagers may only need 7-8 hours. Adults generally require 7-9 hours, but some individuals may feel rested with just 6 hours, while others may need closer to 10 hours to feel fully rested.”
然而，最近的研究表明，一个人所需的睡眠时间可能因年龄、生活方式和总体健康状况而异。例如，婴儿可能需要每天多达17个小时的睡眠时间，而青少年可能只需要7-8小时。成年人通常需要7-9小时，但某些人可能感觉睡6个小时就已经休息充分，而其他人可能需要接近10个小时才能感觉到完全休息。
