Moondust is less dangerous than earth dust, however avoid deep breathing.

• City dust, particularly PM2.5, can cause various health issues, including those affecting newborns and reducing human lifespan.
• A recent study in Life Sciences in Space Research suggests moondust is less harmful than common earth-based particulate matter.
• The study used two versions of lunar dust, LMS-1 and LHS-1, mimicking dust from the moon’s mare and highland regions.
• Large particles from both dust types were toxic and inflammatory only at extremely high concentrations.
• Smaller particles in both dust types that humans could breathe deep into the lungs were less toxic to bronchial cells than PM2.5 particles on Earth.
• Both moondust simulants and earth dust caused alveolar cells to die.
• The study is significant as space agencies like NASA and CNSA are planning to send astronauts to the moon.
• Understanding moondust’s effects on the human body will benefit engineers designing lunar habitats and medical workers in the future.
