# Effects of Electroencephalogram Neurofeedback Intervention on Blood C-Reactive Protein Levels in Astronauts Attending 2-Week Long Analog Moon Mission

## TL;DR

This study explores if EEG neurofeedback can reduce stress in astronauts during a simulated moon mission by measuring blood C-Reactive Protein levels.

## Contribution

The study introduces EEG neurofeedback as a potential non-invasive method to manage physiological stress in extreme isolation scenarios.

## Key findings

- Trends suggest EEG neurofeedback may lower cell stress response levels in isolated individuals.
- Results were not statistically significant but indicate a direction for future research.
- The study provides insights into stress regulation during prolonged isolation.

## Abstract

The human organism is affected by multiple stressors every single day, especially during extremely demanding activities. It needs a method to regulate itself better. One of the stressors that is affecting humans is social isolation. The state of prolonged isolation happens during space missions. In this study, 40 analog astronauts attended a two-week-long mission. The experimental group had EEG neurofeedback training intervention performed on a daily basis, while the control group remained isolated without neurofeedback. The results let us take this non-invasive intervention under consideration, while debating the methods to lower the physiological stress reaction in humans that are exposed to extremely hard circumstances. Although not statistically significant, the trends observed give us direction towards other research to confirm EEG neurofeedback as a method to lower cell stress response levels.
