Children with fetal alcohol spectrum disorders exhibit altered sleeping and eating patterns, as well as other behavioral problems such as attention deficits and depression.


Alterations in these behaviors may indicate that their biological rhythms, which are controlled by circadian systems, have been affected by alcohol exposure during development.

Rodent research confirms that alcohol exposure during a period equivalent to the third human trimester influences the ability to synchronize circadian rhythms to light cues.

Children with fetal alcohol spectrum disorders (FASD) suffer from a variety of behavioral alterations. For example, they may exhibit alterations in sleeping and eating patterns, which may indicate that their circadian systems
