Light exposure during sleep linked to weight gain in women – studyBy The Manila Timeshome/News/Latest Stories/Today's Breaking News/Light exposure during sleep linked to weight gain in women – studyWASHINGTON, D.C.: Women who sleep with the television or a light on in the bedroom may be more likely to gain weight, according to a new study published Monday (Tuesday in Manila). The women were classified according to their level of exposure to artificial light at night (ALAN) which came from a variety of sources, from small nightlights or clock radios to light shining in from the street to televisions or room lights. The correlation remained strong even after controlling for factors like sleep duration, diet, and physical activity. They suggested that the light may be suppressing production of melatonin, thereby disruption circadian rhythm and eating patterns. The authors acknowledged several limitations including that the data was self-reported and they did not know how intense various light sources were.
