The human body experiences significant physiological changes during long-term space travel, particularly due to weightlessness. Key issues include muscle atrophy, decreased bone density, fluid redistribution, and alterations in balance and cardiovascular function. Additionally, astronauts face increased risks of motion sickness, immune system changes, and psychological effects. Addressing these challenges is crucial for future missions that may last for years.
