Has the time change been throwing anyone else off lately? Around here its already light outside around 7am and dark by 6pm! Heres some information on how light (natural and man made light) effects our entire bodies, and how our sleep is affected by it. Read the article below for more information on ways to limit night time blue light exposure (amber-tinted glasses anyone?!) Blue light regulates our secretion of melatonin, the sleep hormone. Exposed to blue light, we limit the production of melatonin, and we stay alert and awake; in the absence of blue light, melatonin production ramps up, and we get sleepy. This system worked quite well for a long time. Reddish light from fire (our formerly primary source of nighttime illumination) has little to no effect on melatonin production, so sleep wasn’t disrupted when we relied on fire. These days, though, we’re subject to a steady barrage of blue light. During the day, blue light (natural or unnatural) isn’t much of a problem because we’re supposed to be awake, but at night, when we’re “supposed” to be getting ready to sleep, we tend to sit in front of blue light-emanating appliances, and our sleep suffers for it.
