Training enhances procedural memory and prepares the person in advance to deal with stressful challenge. Cardiopulmonary resuscitation (CPR) training  is a common example of how training can prepare a nurse in advance for a stressful situation.  Proper nutrition is also important.  It is important to have a source of energy so that your body can deal with the stress—glucose is needed for cognitive function.  Skipping meals can deprive the body of needed resources. However, over use of comfort foods can have an undesired effect.  Exercise is well known to cause positive neurobiological changes and it prepares a person physically.  Without adequate sleep cognitive function declines. Power naps can be helpful but long naps can disrupt the sleep cycle (Posen, 1995). The difference between adaptive and maladaptive coping is that adaptive coping helps resolve problems and maladaptive coping creates more problems.
