科学家们很早就知道光照时间长短控制着我们的生理节奏。 Scientists have long known that our circadian rhythm is regulated by our exposure to light.
同时认为RORA基因有助于维持日常的生理节奏，患有自闭症的人经常睡眠失调，她说。 RORA is also believed to be help maintain the body's daily circadian rhythm, and people with autism frequently experience sleep disturbances, she said.
总要每天在同一个时间起床的方法可以帮你固定住一个生理的节奏。 That process of always getting up at the same time helps to anchor the circadian rhythm.
虽然在昼夜节律中，人与人具有个体差异，但人类基本上都是在白天活动的。 While there are some individual differences in the circadian rhythm, where some individuals are more nocturnal than others, humans are basically a diurnal (day-living) species.
当我们的生物钟周期与外部的昼夜交替周期不一致时，我们就有倒时差的感觉。 Jet lag happens when your circadian rhythm is running on a different day-night cycle than the day-night cycle of the outside world.
如何做：如果你推测你有生理节奏失调症状，采取有规律的睡眠时间的措施。 What to do: If you suspect you have a circadian rhythm disorder, take steps to get your body onto a regular sleep schedule.
研究者表明，这是由于我们的自然睡眠-觉醒周期或者昼夜节律的影响。 This could be due to the effects of our natural sleep-wake cycle, or circadian rhythm, the researchers suggest.
国家睡眠障碍中心出版研究报告解释一旦小孩经历青春期，身体的生理节奏改变了。 The National Center on Sleep Disorders has published studies explaining that once a child goes through puberty, the body’s circadian rhythm changes.
科学家认为睡眠至少由两种方式掌控。 第一个是所谓的昼夜节律，决定我们何时该睡，何时该醒，比如，把一些人变成夜猫。 Scientists think sleep is controlled by at least two processes, one called circadian rhythm that sets the timing of when we go to sleep and when we wake up, turning some into night owls, for instance.
这允许我们身体内的生物钟，叫做生理节律，帮助我们启动和维持我们的睡眠。 This allows our body’s natural clock, called a circadian rhythm, to help initiate and maintain our sleep.
生理节律）情绪以及睡眠模式和精力水平会非常不规则。 (For example, circadian rhythm). Moods, along with sleep patterns and energy levels, can be highly irregular.
时差是我们最为熟悉的生理节奏失调现象，但敏感的生物钟还会因我们睡眠时间不稳定而陷于混乱。 Jet lag is the best known circadian rhythm disorder, but this sensitive inner clock can also be disrupted by changes in routine resulting in an erratic sleep schedule.
周遭的光线会影响大脑功能和人类生理的诸多方面如：生理节奏、心律和荷尔蒙分泌。 Ambient light influences brain functions and different aspects of human physiology such as circadian rhythm, heart rate, and hormone release.
自身节律的个人差异对季节性抑郁症的治疗有重要意义。 这类患者接受光照疗法以重设昼夜节律。 This difference is important for people with seasonal depression, who are treated with light therapy to reset their circadian rhythm.
换句话说，至少对于人类来说，昼夜节律不完全是遗传问题。 In other words, at least for humans, circadian rhythm is not entirely a matter of genetics.
比如，早上醒来的第一件事就是把灯打开调亮，可以改善你的昼夜节奏，并让你更快的清醒过来。 For example, turning on bright lights on first thing in the morning resets your circadian rhythm and essentially makes you more alert.
人和其它动物凭借体内生物钟和着被称为昼夜节律的拍子，这种节律调节睡眠、饮食和其他24小时周期的活动。 Humans and other animals keep time via an internal biological clock known as the circadian rhythm, which regulates 24-hour cycles of sleep, eating, and other activities.
我们的生理节律要求我们在晚上睡觉,"她说。 "Our circadian rhythm wants us to sleep at night," she said.
几乎自然界中所有的物种，从单细胞生物到哺乳动物（包括人类），都具有一种日常活动周期，称为昼夜节律。 Virtually all species in nature, from single-cell organisms to mammals, including humans, exhibit a daily cycle of activity called circadian rhythm.
