A person's chronotype, to use the scientific lingo, is largely a product of their genes.

用科学术语来说，一个人的生物钟类型在很大程度上是他们基因的产物。

Sleep chronotype can have profound effects on productivity, school performance, social functioning and lifestyle habits, experts say.

专家称，睡眠类型对工作效率、学业成绩、社交能力和生活习惯都会产生深远影响。

What determines whether you are or not is something called a chronotype.

决定你是否存在的是一种叫做 chronotype 的东西。

Scientists have found that your sleep chronotype or internal clock is tied to certain genes, but how much sleep you get is another matter.

科学家发现，你的睡眠时间类型或生物钟与某些基因有关，但你获得多少睡眠则是另一回事。

Prof Till Roenneberg of Ludwig-Maximilians University in Munich has studied sleeping patterns and thinks work times should be changed and made more individual to fit in with our chronotypes.

路德维希-马克西米利安-慕尼黑大学的Prof Till对睡眠模式进行了研究，认为工作时间应该进行调整，根据个人的“时型”进行个性化对待。

If sleep chronotype is affecting how our bodies use insulin and impacting metabolism, then being a night owl might be useful in predicting a person's risk for heart disease and type 2 diabetes, Malin added.

马林补充说，如果睡眠类型会影响人体使用胰岛素以及新陈代谢的方式，那么夜猫子习性便可以用来预测一个人患心脏病和 2 型糖尿病的风险。
