American astronaut Marsha Ivins demonstrates the effects of microgravity on her hair in space. The effects of spaceflight on the human body are complex and largely harmful over both short and long term. [1] Significant adverse effects of long-term weightlessness include muscle atrophy and deterioration of the skeleton (spaceflight osteopenia). [2]
For organ dose calculations, NASA uses the model of Billings et al. [23] to represent the self-shielding of the human body in a water-equivalent mass approximation. Consideration of the orientation of the human body relative to vehicle shielding should be made if it is known, especially for SPEs [24]
The goal of space radiation research is to estimate and reduce uncertainties in risk projection models and, if necessary, develop countermeasures and technologies to monitor and treat adverse outcomes to human health and performance that are relevant to space radiation for short-term and career exposures, including acute or late CNS effects ...
[1] [2] The 2005 NASA Authorization Act designated the American segment of the International Space Station as a national laboratory with the goal of increasing the use of the ISS by other federal agencies and the private sector. [3] Research on the ISS improves knowledge about the effects of long-term space exposure on the human body.
In short, it spans the study and support of life in space. Bioastronautics includes many similarities with its sister discipline astronautical hygiene; they both study the hazards that humans may encounter during a space flight. However, astronautical hygiene differs in many respects e.g. in this discipline, once a hazard is identified, the ...
The Digital Astronaut was described as "an integrated, modular modeling and database system that will support space biomedical research and operations, enabling the identification and meaningful interpretation of the medical and physiological research required for human space exploration, and determining the effectiveness of specific individual ...

In addition, due to the toll that spaceflight takes on the human body, medicine use by astronauts have been extensively studied. High rates of sleep medication are taken by astronauts to combat sleep deprivation, disturbances, and other sleep-related disorders caused by an increased presence of CO 2 in the International Space Station.
