Children and teenagers tend to use the term crash out in a casual manner to mean to be so fatigued and fall asleep at high speed. Nevertheless, in certain instances, it can mean emotional overwhelm such as becoming very distressed, closing down or responding emotionally. To illustrate the point, a child may state that he or she crashed out because of a difficult day at school. Active listening assists people in knowing whether the child just requires rest or he or she is experiencing stress, anxiety, and emotional issues that require attention.
