Illnesses and injuries during space missions are a range of medical conditions and injuries that may occur during space flights. Some of these medical conditions occur due to the changes withstood by the human body during space flight itself , while others are injuries that could have occurred on Earth's surface.
Most medical conditions that occur while in flight do not constitute a medical emergency and can be treated with medication, if available. Some documented non-emergency conditions that have occurred while in space include, [3] Space Adaptation Sickness, motion sickness, headache, sleeplessness, back pain, trauma, burns, dermatological conditions, musculoskeletal conditions, respiratory illness ...
Space adaptation syndrome or space sickness is a kind of motion sickness that can occur when one's surroundings visually appear to be in motion, but without a corresponding sense of bodily motion. This incongruous condition can occur during space travel when changes in g-forces compromise one's spatial orientation. [5]
The amount and quality of sleep experienced in space is poor due to highly variable light and dark cycles on flight decks and poor illumination during daytime hours in the spacecraft. Even the habit of looking out of the window before retiring can send the wrong messages to the brain, resulting in poor sleep patterns.
These differences existed before, during, and after flight. Serum folate tended to be lower (P=0.06) in individuals with ophthalmic changes. Preflight serum concentrations of cystathionine and 2-methylcitric acid, and mean in-flight serum folate, were significantly (P<0.05) correlated with changes in refraction (postflight relative to preflight).
The flight was meant to model the planned mission of astronaut Alan Shepard. The mission planned to reach an altitude of 115 miles, and speeds up to 4400 miles per hour. [12] However, the actual flight reached 157 miles and a maximum speed of 5857 miles per hour. [12] During flight, Ham experienced 6.6 minutes of weightlessness.

The project chief engineer Washington Roebling had caisson disease, [26] and endured the after-effects of the disease for the rest of his life. During this project, decompression sickness became known as "The Grecian Bends" or simply "the bends" because affected individuals characteristically bent forward at the hips: this is possibly ...
