New research on motion sickness and space sickness reveals that space sickness is fundamentally a form of motion sickness. Symptoms can be alleviated by restricting head movement and maintaining visual orientation.

Area of Science:

  • Human physiology
  • Aerospace medicine
  • Neuroscience

Background:

  • Motion sickness and space sickness are significant challenges in human spaceflight and terrestrial environments.
  • Understanding the underlying mechanisms and clinical presentation is crucial for astronaut health and passenger comfort.

Purpose of the Study:

  • To review recent experimental results on motion sickness and space sickness from ground and flight studies.
  • To introduce and utilize novel tools for quantitative measurement and analysis of sickness symptoms.
  • To investigate the relationship between laboratory-induced motion sickness and space sickness experienced in orbit.

Main Methods:

  • Development of a mathematical model for motion sickness.
  • Quantitative measurement of skin pallor and blush in ambulatory subjects.

  • Magnitude estimation technique for subjective scaling of nausea and discomfort.
  • Analysis of data from laboratory motion sickness experiments and a Spacelab-1 flight experiment.

    • Main Results:

    • Subjects in prolonged sickness experiments showed hypersensitivity to nauseogenic stimuli.
    • Spacelab-1 observers documented stimulus factors, symptoms, and signs of space sickness.
    • Space sickness exhibits a clinical character distinct from acute laboratory motion sickness.

    Conclusions:

    • Findings from the Spacelab-1 mission support the view that space sickness is fundamentally a type of motion sickness.
    • Subjective alleviation of symptoms was achieved through head movement restriction, stable visual orientation, and proprioceptive cues from body contact.
