How being in space affects the human immune system Today’s Video of the Day comes from NASA and features a look at how being in space affects the human immune system.

Radiation, microgravity, stress, and altered sleep cycles are all factors that can affect the immune systems of astronauts spending an extended period of time in space. To learn more, just hit play! For the space program, called “chips in space,” a team led by Huh and Worthen aims to model a condition called immunosuppression bydeveloping an airway on a chip. Space travel weakens immune system and scientists have figured out why … exerts a dual effect on the human immune system, simultaneously dampening cytotoxic responses. 

NASA studies are looking at the effects of space travel on the human body’s immune system. Life in space does strange things to the human body — itstretches the spine, it turns muscles to jelly, and now new research led by NASA shows that spaceflight confuses.  Space travel weakens our immune systems: Now scientists may know why. Microgravity in space perturbs human physiology and is detrimental for astronaut health. Among the possible causes of space flight-induced alterations in immune responses are exposure to microgravity, exposure to stress, exposure to radiation.
