The raison d'etre of this website is to provide you with hard scientific information which may help you make informed decisions in your quest for health (so far I have blogged concise summaries of over 1,500 scientific studies and have had three books published).

My research is mainly focused on the effects of cholesterol, saturated fat and statin drugs on health. If you know anyone who is worried about their cholesterol levels and heart disease, or has been told to take statin drugs you could send them a link to this website, and to my statin or cholesterol or heart disease books.

The aim of this study was to examine the relationship of cholesterol levels with seasonal affective disorder. The study included 39 seasonal affective disorder patients who were compared with 40 controls.

The study found that seasonal affective disorder patients had significantly lower total cholesterol levels (12% lower) than control subjects.

Pjrek concluded: "The results of this study support the idea that low cholesterol levels may be of pathogenetic importance in seasonal affective disorder."
