Molecular hydrogen has gained attention for its potential antioxidant, anti-inflammatory, and ergogenic effects. However, its impact on blood oxygen saturation and autonomic cardiac regulation under resting conditions remains unclear. This randomized, double-blind, placebo-controlled crossover study investigated the effects of a 60-minute molecular hydrogen inhalation on oxygen saturation and hear
