Beware the anti-depressant drugs. Use sunshine instead.

Beware the anti-depressant drugs. Use sunshine instead.

We have discussed the extraordinary ability of sunlight exposure or other bright-light exposure to profoundly increase the production of serotonin, a brain chemical that is a potent mood enhancer. The most remarkable research on this subject was by Dr. Gavin Lambert and his colleagues in Australia. They measured serotonin levels in response to varying degrees of bright light.[1] To do this, they actually took blood samples from internal jugular veins of 101 men and compared the serotonin concentration of the blood to weather conditions and seasons. The results were remarkable: MEN WHO WERE MEASURED ON A VERY BRIGHT DAY PRODUCED EIGHT TIMES MORE SEROTONIN THAN THOSE WHO WERE MEASURED ON A CLOUDY, DISMAL DAY. They also observed that the effect of bright light was immediate, and that there was no holdover from day to day. SEROTONIN LEVELS WERE ALSO SEVEN TIMES HIGHER IN SUMMER THAN WINTER. NO WONDER WE FEEL SO GOOD WHEN WE ARE OUTSIDE IN THE SUMMERTIME!

The most popular anti-depressant drugs also work by keeping serotonin levels higher, but there are frightening side-effects. The Food and Drug Administration (FDA), indicates that antidepressant medications known as selective serotonin re-uptake inhibitors (SSRI’s) may increase depression in some cases and lead to suicidal thoughts.  Some of the brands involved are Paxil, Lexapro, Prozac, Effexor, Zoloft, Wellbutrin, Luvox, Celexa and Serzone, although the FDA listed 34 drugs.  The entire list is at fda.gov/cder/drug/antidepressants/.  They state the following: “The Food and Drug Administration asks manufacturers of all antidepressant drugs to include in their labeling a boxed warning and expanded warning statements that alert health care providers to an increased risk of suicidality in children and adolescents being treated with these agents, and additional information about the results of pediatric studies.”

The FDA lists several additional warnings and instructions about these drugs:

  • Antidepressants increase the risk of suicidal thinking and behavior (suicidality) in children and adolescents with MDD (major depressive disorder) and other psychiatric disorders.

  • Anyone considering the use of an antidepressant in a child or adolescent for any clinical use must balance the risk of increased suicidality with the clinical need.

  • Patients who are started on therapy should be observed closely for clinical worsening, suicidality, or unusual changes in behavior.

  • Families should be advised to closely observe the patient and to communicate with the prescriber.

Missing are two important facts: (1) SSRI’s increase bone loss.[2] Women who used SSRI’s lose nearly 80% more bone per year than non-users! And as expected, later research shows that SSRI use correlated to a 75% greater likelihood of sustaining a fracture.[3] Secondly, SSRI’s don’t work very well. A meta-analysis of data on SSRI’s submitted to the FDA indicates that placebos (sugar pills) are as effective as SSRI’s in reducing depression; [4] in other words, only drug companies benefit from SSRI’s—not depression sufferers.

Based on that information, it seems prudent to increase our endorphins (and our happiness) through sunlight exposure. It is what nature intended.
