ELI5: Why when people get a traumatic injury the people helping them tell them to "Stay awake" or "Don't fall asleep"

Because a sleeping person cannot report if they anything has changed, and you can't tell if they became unconscious due to their injuries.   Being asleep doesn't make things worse, it makes it harder to treat the injury since the injured person can't describe their symptoms if they're asleep.
