The Right Time for Sex? 享受性事的最佳时间（sina采用
by Leonard DeRogatis, Ph.D.
Some years ago, a Johns Hopkins scientist discovered that human beings experience predictable changes in biological functioning throughout the 24-hour (circadian) cycle of the day.
Metabolic rates, hormone production, energy levels, and many other functions are affected. One predictable change all of us experience is in testosterone, the production of which peaks in the morning hours.
Yet we all have different times of day when we feel we are at our best. Some of us are morning people, others night owls, and we seem to know intuitively which type we are.
These differences can significantly affect the quality of our sex lives. Younger adults are more able to stretch the limits of our circadian rhythms, but that flexibility decreases as we age.
A man who is sexually raring to go when he first awakens will often be confused and frustrated by a partner who behaves like a zombie in the morning.
Later that evening, it may well be that the same woman is energetic and ready to have sex only to find that her partner is too tired or already asleep. In some couples the mismatch involves a woman who's a morning person and a man who's a night owl.
Often, these alterations in energy cycles are ascribed to external events: "I haven't had my coffee yet" or "I had a bear of a day at the office." In fact, they are more likely due to differences in biorhythms. One reason people often report better sex when they go on vacation is that without the constraints of their daily routines, they are again free to do a little stretching of their circadian rhythms.
We cannot easily change our internal clock - it comes with the package. But we can become more aware of how our rhythms relate to our partner's and try to compensate for any significant discrepancies. Sex can often get better as a result. 本人已认领该文编译，48小时后若未提交译文，请其他战友自由认领。 初译：
The Right Time for Sex?
享受性事的最佳时间
Some years ago, a Johns Hopkins scientist discovered that human beings experience predictable changes in biological functioning throughout the 24-hour (circadian) cycle of the day.
早些年，约翰斯·霍普金斯大学的一位科学家发现，人类在全天24小时的昼夜节律周期中的生物功能改变可以被预测。
Metabolic rates, hormone production, energy levels, and many other functions are affected. One predictable change all of us experience is in testosterone, the production of which peaks in the morning hours.
受影响的生物功能包括：代谢速率，激素分泌，体能状况，以及许多其他功能。 一个我们都有切身体验的生物功能改变就是睾酮水平的改变，睾酮在早晨分泌最为旺盛。
Yet we all have different times of day when we feel we are at our best. Some of us are morning people, others night owls, and we seem to know intuitively which type we are.
然而不同的人在一天中最佳状态的出现时间也有所不同。 一些人属于晨间鸟类型，而一些人则是夜猫子类型，而且我们似乎单凭直觉就已知道自己是属于哪种类型。
These differences can significantly affect the quality of our sex lives. Younger adults are more able to stretch the limits of our circadian rhythms, but that flexibility decreases as we age.
这些生物功能改变会明显影响我们的性生活质量。 青年人更容易挣脱生理节律的束缚，但是当我们变老时，这种能力也就随之下降。
A man who is sexually raring to go when he first awakens will often be confused and frustrated by a partner who behaves like a zombie in the morning.
一个大清早醒来便渴望性欲得到满足的男人，看到伴侣表现得一副死鱼像时，常常会满脸的困惑和失望。
Later that evening, it may well be that the same woman is energetic and ready to have sex only to find that her partner is too tired or already asleep. In some couples the mismatch involves a woman who's a morning person and a man who's a night owl.
当天晚上，当这位精力旺盛的伴侣已经做好发生性关系的准备时，不料却发现先生过于疲倦或是已经呼呼大睡了。另外一些性兴奋时段错位的夫妇，则是女方习惯早起，而男方习惯晚睡。
Often, these alterations in energy cycles are ascribed to external events: "I haven't had my coffee yet" or "I had a bear of a day at the office." In fact, they are more likely due to differences in biorhythms. One reason people often report better sex when they go on vacation is that without the constraints of their daily routines, they are again free to do a little stretching of their circadian rhythms.
人们常常将体能循环方面的这些改变归因于外部事件，诸如"我还没喝咖啡"或是"我在办公室忙了一整天。" 实际上，这些改变更可能是由于生物节律差异性而引起。人们在度假时更能享受美好性事，其中一个原因就是他们摆脱了日常工作的束缚，能够再次毫无思想负担地稍微使自己的昼夜节律更加弹性化。
