title: Psychosomatic reactions to a stressful environment and an attempt at pharmacological modification.
abstract: BACKGROUND
  Extreme environmental conditions significantly influence the functioning of the human organism and trigger distinct stress reactions. In our study we attempted to create an experimental model of complex stress conditions.
  
  
  METHODS
  Healthy male volunteers were isolated, deprived of food and sleep, and exposed to extreme temperatures for 5 consecutive days. Physical fitness and selected somatic parameters and biochemical stress markers were measured in the tested subjects. In addition, changes in behavior and mental status were assessed by means of a set of psychological tests. Finally, the effects of pharmacological modification (administration of clobazam and tramadol) on psychosomatic stress reactions were tested.
  
  
  CONCLUSIONS
  The results indicate that our experimental stress conditions slightly altered the mental functions of the subjects, increased their anxiety level, hampered their physical efficiency, and led to weight loss. The administration of the drugs beneficially influenced the subjects' memory and physical efficiency.
