Sleep deprivation significantly impairs psychological and physical performance, affecting vigilance, memory, and exercise capacity. This review details sleep

Area of Science:

  • Physiology
  • Psychology
  • Occupational Health

Background:

  • Sleep is crucial for performance, health, and safety across various professions.
  • Sleep deprivation negatively impacts cognitive functions like vigilance and memory.
  • Physical performance declines with sleep loss, affecting exercise capacity and perceived exertion.

Purpose of the Study:

  • To review the functions of sleep and its impact on human performance.
  • To detail the detrimental effects of sleep deprivation on psychological and physical capabilities.
  • To examine sleep challenges in specific populations like shift workers and the military.

Main Methods:

  • Literature review of studies on sleep, sleep deprivation, and performance.
  • Analysis of psychological and physical performance metrics affected by sleep loss.

  • Consideration of environmental factors like high altitude on sleep and performance.

    • Main Results:

    • Sleep deprivation impairs cognitive functions (vigilance, memory, attention) and physical abilities (exercise capacity).
    • High altitude exacerbates sleep issues, affecting acclimatization, thermoregulation, and cognition.
    • Certain aspects like muscle contractile properties and anaerobic power are less affected by sleep deprivation.

    Conclusions:

    • Effective sleep management is vital for maintaining performance, health, and safety.
    • Understanding 'sleepiness' is key to mitigating the effects of sleep deprivation.
    • Sustained operations, especially in extreme environments, require careful consideration of sleep-work schedules.
