Cardiovascular and hormonal changes induced by isolation and confinement

The cardiovascular changes induced by microgravity are in general described as the result of the loss of hydrostatic pressure. Other factors are also important: restricted environment with 1) elimination of mobility, action and 2) isolation always found in space environment or during simulation studies. Several studies indicate an analogy between microgravity and confinement. The results of simulation studies could be misinterpreted without a control confinement study present in the protocol.
