Is Cold Exposure good for energy & vitality?

The evidence points that way, though it's not yet conclusive. Meta-analyses consistently find cold water immersion reduces delayed-onset muscle soreness and modestly improves perceived recovery after strenuous exercise, with effects present across team-sport and endurance contexts and influenced by water temperature and immersion duration. That's reflected in an evidence score of 58/100 for its role in energy & vitality, drawn from 10 studies (1 RCT), with an estimated impact on longevity rated limited (25/100).
