Evidence:  Report
Risk Master Logic Diagram:  Not Available
Point of Contact:  Stuart Lee
HRP Risk Status: Inactive [no current ongoing research]
Inactive Rationale
Research on this risk is being phased out since mature mitigation solutions exist (fluid loading, compression garments) and are being transitioned to operations. The only current research on this risk is opportunistic work; no targeted solicitations will be released.

Risk Statement
Given that there is cardiovascular adaptation during exposure to the spaceflight environment (including micro-gravity), there is a possibility that crewmembers will suffer from orthostatic intolerance upon re-exposure to gravity.
