Dim light at night disrupts molecular circadian rhythms and increases body weight.
With the exception of high latitudes, life has evolved under bright days and dark nights. Most organisms have developed endogenously driven circadian rhythms that are synchronized to this daily light/dark cycle. In recent years, humans have shifted away from the naturally occurring solar light cycle in favor of artificial and sometimes irregular light schedules produced by electric lighting. Ex...
متن کاملResidential magnetic fields, light-at-night, and nocturnal urinary 6-sulfatoxymelatonin concentration in women.
Exposure to 60-Hz magnetic fields may increase breast cancer risk by suppressing the normal nocturnal rise in melatonin. This 1994-1996 Washington State study investigated whether such exposure was associated with lower nocturnal urinary concentration of 6-sulfatoxymelatonin in 203 women aged 20-74 years with no history of breast cancer. Each woman was interviewed and provided data on the follo...

concluded that "shift-work that involves circadian disruption is probably carcinogenic to humans" [1]. This conclusion was based upon limited evidence in humans [2, 3] and sufficient evidence in experimental animals [4, 5]. The current experimental results of Vinogradova and colleagues from Petrozavodsk and St. Petersburg render further support to this important issue and indicate a number of h...
متن کاملElectric light, particularly at night, disrupts human circadian rhythmicity: is that a problem?
Over the past 3 billion years, an endogenous circadian rhythmicity has developed in almost all life forms in which daily oscillations in physiology occur. This allows for anticipation of sunrise and sunset. This physiological rhythmicity is kept at precisely 24 h by the daily cycle of sunlight and dark. However, since the introduction of electric lighting, there has been inadequate light during...
متن کاملDim light at night disrupts the short-day response in Siberian hamsters.
Photoperiodic regulation of physiology, morphology, and behavior is crucial for many animals to survive seasonally variable conditions unfavorable for reproduction and survival. The photoperiodic response in mammals is mediated by nocturnal secretion of melatonin under the control of a circadian clock. However, artificial light at night caused by recent urbanization may disrupt the circadian cl...
