Study Summary

The goal of this clinical trial is to learn how the FDA-cleared Q-Collar device affects brain blood flow regulation during rest and exercise in healthy adults. The main questions this study aims to answer are: 1. How does the Q-Collar affect brain blood flow when there are quick changes in blood pressure, like when standing up quickly, or when breathing against resistance? 2. How does the Q-Collar affect brain blood flow during exercise? Researchers will compare sessions where participants wear the Q-Collar to sessions where they do not wear the device to see if the Q-Collar improves brain blood flow during both rest and exercise. Participants will: * Complete two study visits, each 1 to 4 weeks apart. * Perform a series of tasks, including standing tests, breathing tests, and exercise on a stationary bike, while their heart rate, brain blood flow, and other body functions are monitored. * Wear the Q-Collar during one of the sessions and not wear it during the other session. The order of the sessions will be randomly assigned.

Primary Outcome

The slope of the autoregulatory curve, representing the change in cerebral blood flow in response to rapid shifts in blood pressure during the sit-to-stand transition.
