Scientist test the effect of multicolor lighting on improving people’s psychological state

As missions for deep space exploration and space habitats are put on the agenda, astronauts need to withstand being tested by multiple stressors in confined and isolated conditions during such long flights.

A large number of studies have also found that crew members on long-term missions on the Antarctic Space Simulation Station are extremely susceptible to psychological problems caused by visual monotony and monochromatic colors.

In a research paper recently published in Space: Science & Technology, Ao Jiang from European Space Agency conducted a study to test whether multicolor lighting can improve people’s psychological state in an isolated and confined environment over a period of seven days.

In future space exploration, colored lighting or other sensory adjustment interventions could be used in addition to teamwork and collective life to reduce negative emotions and anxiety feelings.
