Earth Applications


The benefits gained from the Human Factors and Performance Team’s research extend to health care and many other occupations on Earth. The Team has applications for Earth use in the following ways:
  • Lighting recommendations – type, timing and intensity – to improve the safety and well-being of people working in jobs requiring international travel, shift work and extended schedules;
  • Better models for assessing environmental exposure to particulate matter; and
  • Improved ability to target drugs to specific areas of the lung, making it possible to achieve optimal results with small quantities of drugs and to minimize side effects.




Researchers are working to provide lighting in spaceflight that improves the sleep and biological rhythms of astronauts. Prototype lighting systems enriched in the blue portion of the spectrum are currently being tested because these wavelengths are potent suppressors of human melatonin production.
