Key result
Six hours of water immersion reduced sympathetic and elevated parasympathetic activity during cold pressor and handgrip tests, but had opposite effects during head-up tilt (P<0.05).
Why the study?
How does 6 hours of water immersion affect cardiovascular and autonomic responses to physiological stressors in healthy men?
Population

May alter autonomic test interpretation post-immersion in healthy men; hypothesis-generating and leaves open clinical relevance.
How does 6 hours of water immersion affect cardiovascular and autonomic responses to physiological stressors in healthy men?
p-value: p=<0.05
Prolonged water immersion alters autonomic and cardiovascular responses to subsequent physiological stressors in healthy men.
Florian et al. (2013) studied Healthy (n=10). Water immersion vs. Before water immersion was evaluated on Cardiovascular and autonomic responses to physiological stressors (p=<0.05). Six hours of water immersion reduced sympathetic and elevated parasympathetic activity during cold pressor and handgrip tests, but had opposite effects during head-up tilt (P<0.05).
