Effect of Sleep Restriction on Decision Making and Inflammation

November 20, 2013 updated by: SAUVET Fabien, Institut de Recherche Biomedicale des Armees
  • hypothesis: sleep restriction in healthy subject trigger alteration of decision making associated with immuno-inflammatory changes
  • inclusion criterias: healthy subjects, men, under 35 years, BMI<26, no sleep troubles, intermediate chronotype
  • design: 12 subjects, longitudinal study 2 days of baseline, 7 night of sleep restriction (4h sleep/night), recovery (1, 2, 3 and 9 normal sleep nights).
  • parameters: decision making tests, reaction time, wakefulness test, biological parameters (cathecholamines, pro-inflammatory cytokines...), heart rate, blood pressure
  • control of sleep restriction: continuous polysomnographic survey
