Night light and its role in alleviating peri/menopause discomfort

Body: 

Hi All
Have a look at this link. http://www.westonaprice.org/women/fertility.html .

Down the bottom of the page is a section on night lighting. Has anybody heard of this?

And who are the Weston A Price Foundation? It all sounds very commonsense to an earthmother like me, but is there a hidden agenda?

Cheers
