Space sickness: the hidden health toll of microgravity

Original: 🔭 Space sickness is more than nausea in zero gravity. Microgravity can disrupt balance, vision, bones and muscles. Long

Space sickness goes beyond nausea in zero gravity. Microgravity can disrupt balance and vision while weakening bones and muscles, and long missions add radiation exposure, sleep problems and immune risks. Crews heading to Mars would face these health threats far from immediate medical support, making astronaut health a growing concern as space agencies plan deep-space missions.

Why now: Ongoing interest in astronaut health as agencies prepare for long-duration missions to the Moon and Mars
