Bone Density Loss
Bone density loss refers to the reduction in the amount of mineral matter per square centimeter of bones, which can lead to weakened bones and increased risk of fractures. In space and astronautical engineering context, bone density loss is a common health issue experienced by astronauts during long-duration space missions due to the lack of gravity. In microgravity, the body experiences a decrease in mechanical loading, which leads to a decrease in bone formation and an increase in bone resorption. This can result in a loss of bone density of up to 1-2% per month. To mitigate bone density loss, astronauts perform daily exercise routines and take calcium and vitamin D supplements. Additionally, researchers are exploring the use of artificial gravity and other countermeasures to prevent bone density loss during space missions.
