Abstract
The aim of the study is to broaden the knowledge about the impact of changing conditions on the autonomic nervous system and cognitive functions, as well as the potential applications of pupillometry in the assessment of astronauts' health. The study was conducted during analog missions in Analog Astronaut Training Centre: the LUNAR 84 and the largest analog mission in the world- COLONY 1, where 30 analog astronauts spent a week in isolation. The measurements were obtained with usage of the military grade human gyroscope and precise pupilometer. The acquisition was made on a sample of 19 analog astronauts in five different positions and conditions. Every one of them was strapped onto the gyroscope to change their positions easily and to obtain repetitive readings. Additionally astronauts had to take basic measurements like: blood pressure, body temperature and saturation right before and immediately after the gyro activity. As the results of measurements we received PD distance- a range between pupils. PD distance is in fact changing slightly in accordance to conditions analog astronauts are exposed to which is fairly novel in studies of pupillometry. Being breathless while standing vertical and being vertical without any additional instructions are having notably smallest measurements of PD distance, on average they both count for 65,12mm. Being upside down or laying on the right side is responsible for average measurement almost a 0,5 mm higher. For instance average PD distance while lying horizontally is exactly 0.44mm greater than when standing vertically, representing a 1% increase. No correlation between basic parameters and pupillometry results was found. These findings underscore pupillometry's potential as a non-invasive method of astronaut health monitoring and point to so far undiscovered relationship between it and physiological adaptability. According to the study, pupillometry may be a useful biomarker for autonomic nervous system reactions under changed gravity conditions. This could have an impact on space medicine, astronaut training, and the monitoring of human performance in harsh environments. The underlying mechanisms and wider applicability of these discoveries require more investigation.
