Just when I thought I had heard every cause of erectile dysfunction…along comes a new one. According to some researchers, sexual problems are caused by “over-illumination” — the use of too much bright light in our environment.

According to this view, chronic exposure to bright light (such as working in an office or Wal-Mart for 8 hours) causes a stress response in the body, so that it releases adrenalin. This adrenalin causes blood vessels to get smaller (vasoconstriction), causing hypertension and erectile dysfunction.

So, it’s all Edison’s fault.

The cure is fixing the lighting so it is more like sunlight.

By the way, speaking of “innovators,” I just stumbled on this gem, which I had to share:

Modern drug therapy for ED made a significant advance in 1983 when British physiologist Giles Brindley, Ph.D. dropped his trousers and demonstrated to a shocked American Urological Association audience his phentolamine-induced erection. The drug Brindley injected into his penis was a non-specific vasodilator, an alpha-blocking agent, and the mechanism of action was clearly corporal smooth muscle relaxation. The effect that Brindley discovered established the fundamentals for the later development of specific, safe, orally-effective drug therapies.
