Actor Kim Seok-hoon was shocked by the two faces of oxygen.
SBS knowledge and health variety show "Three perspectives" unpacks, from scholars' fascinating stories related to the world-famous cave paintings to the great oxygenation event about 2.4 billion years ago—one of the largest events in Earth's history—through three perspectives.
In the episode of SBS "Three perspectives" airing at 8:35 a.m. on the 26th, MC Kim Seok-hoon, So Seulji, science writer Kwak Jae-sik, docent Rhee Chang-yong, family medicine specialist Seo Myung-won, and pharmacist Jang Se-gyeong explore oxygen, which can both sustain and kill the body.
Oxygen is often described as a "double-edged sword." You may have seen the metal we use change color over time. Bronze mirrors, the Statue of Liberty, and the roof of the National Assembly also originally shone with golden and reddish hues. "Three perspectives" explains the reason for these changes as the process of oxidation and points out that this process is closely linked to our bodies.
About 1–3% of the oxygen we normally inhale is converted into reactive oxygen species. Reactive oxygen species are highly reactive, difficult to control, and have the property of attacking cells. We use about 500 liters of oxygen a day, of which about 15 liters is converted into the form of reactive oxygen species that attack cells.
Pharmacist Jang Se-gyeong warns that if reactive oxygen species continue to increase, they can affect not only aging but also diabetes, cardiovascular disease, and neurodegenerative diseases.
Actor Kim Seok-hoon and announcer So Seulji focus on the fact that oxygen, long thought to be essential for sustaining life, can instead threaten life, and they address related questions one by one.
"Three perspectives" will approach oxygen from scientific and medical viewpoints—covering its historical significance, the dangers of reactive oxygen species, and technologies that defend against them—to help viewers' understanding.
