Healthy volunteers needed to map the Body's 'Autopilot' system

This study aims to better understand the autonomic nervous system (ANS), which controls things like heart rate and breathing without us thinking about it. Researchers will use simple, noninvasive tests (like cold water and deep breathing) to measure how the ANS responds in 48 healthy adults aged 18-60. They will also test if a gentle nerve stimulation device can change these responses. The goal is to create a way to detect early signs of ANS problems in the future.
