Introduction
Molecular hydrogen (H2) was once considered a physiologically inert and non-functional gas. This traditional view has dramatically changed over the past decades as research unveiled its therapeutic potential. Experimental and clinical studies have shown that molecular hydrogen exhibits anti-inflammatory, anti-apoptotic, and strong selective antioxidant effects, making it a promising agent for a variety of health applications (Ohsawa et al., 2007; Ohta, 2014).
One of the compelling benefits under exploration is how molecular hydrogen influences metabolism – particularly, its role in modulating respiratory gas exchange and fat oxidation during rest. Recent investigations suggest that hydrogen gas inhalation can beneficially alter metabolic parameters, improve lipid and carbohydrate metabolism, and enhance mitochondrial function.
