In the future, industrialisation of space and exploration of inner and outer planets will require humans to endure longer and longer periods in space. The majority of current data comes from missions of short duration and so some of the long-term physiological effects of living in space are still unknown.
Space travel exposes people to quite a different environment, posing a range of physiological and psychological challenges, especially with prolonged exposure, according to Afshin Beheshti ...
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.
Space exploration also gives scientists the ability to perform experiments in other settings and expand humanity's knowledge. [67] Another claim is that space exploration is a necessity to humankind and that staying on Earth will eventually lead to extinction. Some of the reasons are lack of natural resources, comets, nuclear war, and worldwide ...
This is known as the "Fitness for Duty Standards". Space crews' current nominal number of work hours is 6.5 hours per day, and weekly work time should not exceed 48 hours. NASA defines critical workload overload for a space flight crew as 10-hour work days for 3 days per work week, or more than 60 hours per week (NASA STD-3001, Vol. 1 [11]).
University researchers have teamed with astronauts to test an experimental drug, rebecsinib, they say appears to act as a "kill switch" for cancer—at least in space, where aging is accelerated.
[80] [81] In the first 28 U.S. Space Shuttle flights (2–11 d duration), serum insulin levels (n = 129) were elevated by 55% on landing day compared to before flight. [82] Russian space life science investigators reported two-fold or greater increases in insulin levels in three cosmonauts within 1 day after they returned from a 237-d flight. [83]
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 ...
