Why Does Oxygen Slowly Kill Us If We Need It to Live?

If humans need oxygen to survive, why does it also slowly kill us? This video explores the fascinating and paradoxical science behind oxygen's role in the human body — from fuelling every cell to quietly driving the ageing process through oxidative stress and free radical damage. It unpacks how the very molecule that sustains life is also responsible for cellular degradation over time, offering a clear and engaging explanation of one of biology's most thought-provoking contradictions. #ScienceExplained #OxygenParadox #HumanBiology #Ageing #Lykstage #LykstageVideo #LykstageCreator #LykstageCommunity
