TL;DR
Breathing in molecular hydrogen gas can help reduce the size and severity of pressure ulcers (bedsores) by protecting the skin and reducing inflammation.
Key Finding
Hydrogen gas inhalation significantly reduced pressure ulcer formation in mice by decreasing oxidative stress (cellular damage from harmful molecules), suppressing inflammatory responses, and promoting wound healing factors.
Summary
Researchers tested whether breathing hydrogen gas could help prevent pressure ulcers (severe skin wounds caused by prolonged pressure) in mice. They found that hydrogen gas inhalation reduced wound size, decreased DNA damage and cell death in skin tissue, lowered harmful molecules called free radicals, and reduced inflammation while boosting the skin's natural healing processes.
Practical Takeaway
While this mouse study suggests hydrogen gas may help protect against pressure ulcer formation through multiple protective mechanisms, it is early-stage research that has not yet been tested in humans. The findings are promising but cannot yet be applied to human pressure ulcer prevention or treatment without further clinical studies.
Abstract
AbstractPressure ulcer formation depends on various factors among which repetitive ischaemia/reperfusion(I/R) injury plays a vital role. Molecular hydrogen (H2) was reported to have protective effects on I/R injuries of various internal organs. In this study, we investigated the effects of H2 inhalation on pressure ulcer and the underlying mechanisms. H2 inhalation significantly reduced wound area, 8‐oxo‐dG level (oxidative DNA damage) and cell apoptosis rates in skin lesions. H2 remarkably decreased ROS accumulation and enhanced antioxidant enzymes activities by up‐regulating expression of Nrf2 and its downstream components in wound tissue and/or H2O2‐treated endothelia. Meanwhile, H2 inhibited the overexpression of MCP‐1, E‐selectin, P‐selectin and ICAM‐1 in oxidant‐induced endothelia and reduced inflammatory cells infiltration and proinflammatory cytokines (TNF‐α, IL‐1, IL‐6 and IL‐8) production in the wound. Furthermore, H2 promoted the expression of pro‐healing factors (IL‐22, TGF‐β, VEGF and IGF1) and inhibited the production of MMP9 in wound tissue in parallel with acceleration of cutaneous collagen synthesis. Taken together, these data indicated that H2 inhalation suppressed the formation of pressure ulcer in a mouse model. Molecular hydrogen has potentials as a novel and alternative therapy for severe pressure ulcer. The therapeutic effects of molecular hydrogen might be related to its antioxidant, anti‐inflammatory, pro‐healing actions.
