Washington, DC—The growth of waistlines over the past few decades coincided with a major societal change – increased exposure to electric lights during the night. Whether the source is the tiny screens of mobile devices or overhead lamps, nighttime light exposure is disrupting circadian rhythms and likely fueling obesity rates, according to a new review of past research published today in the Endocrine Society’s journal Endocrine Reviews.

Endocrine Society member Eve Van Cauter PhD, an expert on sleep, health and metabolism, and Endocrine Reviews article author Laura Fonken, PhD, are prepared to offer comment on many aspects of this issue, including:

• What impact does nighttime light exposure have on circadian rhythms and metabolism?• How widespread is the problem of exposure to unnatural light cycles?• What effect does sleep disturbance have on eating habits and weight?• Why has nighttime light exposure been considered innocuous for such a long time?• What can be done to counter the metabolic effects of nighttime light exposure?

WHAT: A new review identifies a growing body of evidence showing pervasive nighttime light exposure disrupts circadian rhythms and may contribute to rising obesity rates in developed nations. The review is being published in the Endocrine Society’s journal Endocrine Reviews.
