In recent vears. the develoment of hydrogen biolooy has been yen rapid. Many scholars have proved thatthev can preven and initevene hundreds of diseases and iniuries by breathing, drinking or injecting hydrogen water. Alhough the medical research on hydrogen is still on the way, the antionxidant and anti-inflammatory effects of hydrogen have been very clear, and the great biosafety of hydrogen is an important prerequisite for the availability of hydrogen The elderly are in relativel poor physical condition, prone to muliple diseases and chronic diseases, and need to be more cautious in drug use. Hvdrogen as a biomedical tool with great safety and broad spectrum, will play a unique and key role. Safe hydrogen with medical efiects wil be a great blessing for the elderly.Studies have shown that hydrogen has preventive and interventional effects on ischemic reperfusion injury of vanious organs, radiation injury of vanious tissues, cardiovascular and cerebrovascular diseases, arerisclerosis, diabeles, hyperension, neurodegenerative diseases and so on. The qreatbiosafely of hydrogen and the safety of hydrogen in human body have been a large number ofsuficient research evidence. which is an imporantprerequisite for hydrogen to be used as a preventive intervention tool for many chronic diseases. in paricular, geriatric diseases are mosty chronic diseasesthat reguire long-term intervention, Hydrogen is almost a perfect tool for geriatric medicine
