243. Salivary stress markers and psychological stress in
simulated microgravity: 21 days in 6° head-down tilt.
Rai B, Kaur J.
Catholic University Leuven, Belgium.
Spaceflight occurs in an environment of temperature extremes, microgravity, solar and
galactic cosmic radiation, lack of atmospheric pressure, and high-speed micrometeorites. Exposure
to microgravity and the space environment during space missions of short and long duration has
important medical and health implications for astronauts. Psychological well-being is of increasing
importance in planned spaceflights and interplanetary missions of long duration. The 6° head-down
tilt (HDT) is an established method of mimicking low gravity on earth. The aim of the present study
was to determine the effects of 21 days of HDT on psychological stress in 12 healthy male
volunteers.
Psychological state was assessed by the current stress test, and chromogranin-A (CgA),
cortisol, alpha-amylase, and beta-endorphin were measured in saliva. After one week of HDT, all
volunteers developed psychological stress, and secretion of CgA, cortisol, alpha-amylase,
and beta-endorphin were all significantly higher. Thus, 6° HDT appears to be a valid model to
induce psychological stress changes in the immune system, changes that might also be
encountered by astronauts and cosmonauts during both a short stay in space, such as that required
while orbiting a space station, and in longer spaceflights.
