The Cause of Internet and TV Addiction?
Low Bilirubin Levels
Seasonal Affective Disorder (SAD)
"People suffering from SAD have lower nighttime levels of bilirubin in their blood, writes lead author Dan A. Oren, MD, associate professor of psychiatry at Yale University School of Medicine. His study appears in the current Society of Biological Psychiatry journal"
Increasing Bilirubin Levels
Light Box Daily Light Therapy
"During the mornings, patients had a course of 'light box daily light therapy,' a standard treatment for SAD that consists of one hour under a bright light…At the end of two weeks, the treated patients had significantly higher bilirubin levels than before treatment…The treated patients also showed fewer depressive symptoms than before."
"Bilirubin is known to have a circadian rhythm; levels gradually increase in the blood during the night and decrease during the day."
Elevated Bilirubin Levels
"When your bilirubin is increased, it usually means that there is a problem in your liver or your red blood cells are being destroyed too quickly. When bilirubin is greatly elevated, then a person may appear jaundiced (yellow) in their skin and in the whites of their eyes (sclerae)."
Common Causes: Gilbert's Syndrome
Note: Gilbert's syndrome is also referred to as Gilbert syndrome.
"Gilbert's Syndrome is a benign condition."
Common Causes: Gilbert's Syndrome: Symptoms
"The syndrome is characterized by intermittent jaundice in the absence of hemolysis [increased red cell destruction] or underlying liver disease. The hyperbilirubinemia is mild and, by definition, less than 6 mg/dL. However, most patients exhibit levels of less than 3 mg/dL. Considerable daily and seasonal variations are observed, and bilirubin levels occasionally may be normal in as many as one third of patients."
Common Causes: Gilbert's Syndrome: Causes
"Gilbert syndrome may be precipitated by dehydration, fasting, menstrual periods, or stress, such as an intercurrent illness or vigorous exercise. Patients may complain of vague abdominal discomfort and general fatigue for which no cause is found. These episodes resolve spontaneously, and no treatment is required except for supportive care."
Effects of Bilirubin
"Bilirubin is the most abundant known circulating antioxidant and may protect neurological pathways that regulate moods, he says…His future studies will help determine whether low bilirubin causes SAD, whether it contributes to the vulnerability to depression, or if it is a marker for the disorder."
