Mortal injury and sleep

itnifl used Ask the Experts™
I am looking for information or articles about the effect of sleep when a person is in any way mortally injured. The classic reaction is to avoid sleep in order to keep alive. The victim of the injury tries to keep awake in order to not die. Does the situation imply that the victim is feeling drowsy or sleepy as a reaction to the injury and as a process of dying? What are the chemical and physical processes that occur in the body in the process of death or near death related to a mortal injury, and does not sleeping actually keep the person alive?

 I think that the energy that keep us alive just changes in another type of energy.


I am not sure what you are aiming at. Since a dead body will fail to sustain itself with all the processes that it needs, all the chemical structures in the body will eventually get to be a part of other processes in whatever surroundings there are. Thus energy is transformed. On what level or in wich way you are aiming, I am not sure. Heat leaves the body and son on and so forth.

However, this does not answer my questions. I want to know if trying to stay awake will help you to stay alive. If so, why, or why not?

Immediately following an injury the patient may want to sleep just to remove themselves from the pain and discomfort. Ambulance teams will prefer that the patient stays awake for a number of reasons, not all to do with recovery. They will want to ask where the pain is, what type of injury was it? The patient is the best person to tell them what happened an help them assess the situation better. If the patient manages to stay awake and talking the medics know that most of the vital organs are still working. If the patient suddenly drops unconcious then the medics have to do a number of things to keep the patient breathing and keep the heart pumping etc. All of which might not be needed if the patient stays awake.
Once transferred to a hospital where there are all kinds of monitoring equipment, the patient can be allowed to sleep as doctors can check their state much easier.
The initial 'try to stay awake' is so that the medics have an early warning if there is something seriously wrong, they can't assess the situation fully while at a roadside or travelling in an ambulance - their job is to keep the patient alive until they get to hospital.
Think at this:
A special situation of your question is at North Pole : when normal people traveling there may die frozen. Then a kind of sleep precedes the death.
