BPA exposure during pregnancy can alter circadian rhythms

(The Endocrine Society) Exposure to the widely used chemical bisphenol A (BPA) during pregnancy, even at levels lower than the regulated 'safe' human exposure level, can lead to changes in circadian rhythms, according to a mice study to be presented Monday at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La. The researchers report these changes may be a contributing factor in hyperactivity seen in BPA-exposed mice.
