More on Sun Exposure and Depression

Does sun exposure help fight depression? Of course!

By Marc Sorenson, EdD. Sunlight Exposure

Although this blog has discussed sun exposure and its affects on depression, there is some information that I may have neglected to mention. It has been shown that depressed psychiatric patients who resided in sunny rooms stayed in the hospital 2.6 fewer days than those who had “dull” rooms.[1] The sunny rooms had windows, so it is likely that endorphins and serotonin, created by the sun entering the windows, were the natural “uppers” by which the patients felt better. Nitric oxide, produced by UVA light exposure, could also have played a part.

Another of those dull rooms is the one that houses the TV. An interesting study from the University of Pittsburgh found that the more TV teenagers watched, the more likely they were to be depressed as adults.[2] The study author theorized that because there is so much depressing news and programming on TV, the more exposure, the more the internalizing or the depressing programming. For each hour of TV watched, the rate of depression increased significantly.

The researchers may be correct, or it could be that hours of sedentary life in front of the TV, watching commercials for junk food, leads to obesity and poor health as the teenager ages.  We have another theory that may supplant, or at least add to those theories. It is possible that years of unnatural indoor habits create deficiency of the aforementioned vitamin D, nitric oxide, endorphins and serotonin, which may have long-term effects. Combined with the deleterious influences of excessive TV watching, that could be a recipe for depression and health disasters. Sun exposure and vitamin D are absolutely necessary for human health and happiness.  An indoor lifestyle is unnatural and damaging to the human body and psyche.

Safely embrace the sun and obtain its “feel-good” effects.
