So, there are actually two golden hours every day. GOLDEN HOUR the Golden Hour: Scienti®c Fact or Medical "Urban Legend"?". Roughly speaking, the golden hour is the first hour of light after sunrise and the last hour of light before sunset.

Atls, Advanced Trauma Life Support Program for Doctors. ^ American College of Surgeons (2008).There are different critical periods for different injuries. The physician Bryan Bledsoe, an outspoken critic of the golden hour and other EMS "myths" like critical incident stress management, has indicated that the peer reviewed medical literature does not demonstrate any "magical time" for saving critical patients. While most medical professionals agree that delays in definitive care are undesirable, recent peer reviewed literature casts doubt on the validity of the 'golden hour' as it appears to lack a scientific basis. You might not die right then it may be three days or two weeks later - but something has happened in your body that is irreparable." Controversy If you are critically injured you have less than 60 minutes to survive. The R Adams Cowley Shock Trauma Center section of the University of Maryland Medical Center's website quotes Cowley as saying, "There is a golden hour between life and death. The concept of the "Golden Hour" may have been derived from the French military's World War I data. In photography, the golden hour is the period of daytime shortly after sunrise or before sunset, during which daylight is redder and softer than when the sun. R Adams Cowley is credited with promoting this concept, first in his capacity as a military surgeon and later as head of the University of Maryland Shock Trauma Center. The recommended amount of time for emergency medical services is less than 10 minutes at the location of the trauma before transporting. Because some injuries can cause people to deteriorate extremely rapidly, the lag time between injury and treatment should ideally be kept to a bare minimum this has come to be specified as no more than 60 minutes, after which time the survival rate for people who have sustained trauma is alleged to fall off dramatically. It therefore becomes a priority to transport people with severe trauma as fast as possible to specialists, most often found at a hospital trauma center, for treatment. Complications such as shock may occur if the person is not managed appropriately and expeditiously. Cases of severe trauma, especially internal bleeding, require surgical intervention.
