Study shows bright light can improve fertility

Bright light is often used to treat Seasonal Affective Disorder, which goes by the contrived acronym of SAD. But a recent study suggests it also might improve fertility.

The study was performed at the Russian Academy of Medical Sciences and its purpose was to determine if bright light treatment could shorten menstrual cycles. It did not. But it did seem to have an affect on the fertility of the women in the study.

However, there were only 22 women total in the study and 4 got pregnant. Numbers that small would seem to not be statistically significant.
