Astronauts age more slowly than people on Earth. The difference isn't noticeable though — after spending six months on the ISS, astronauts age about 0.005 seconds less than the rest of us.
Put another way, the space ship sees the image change from a red-shift (slower aging of the image) to a blue-shift (faster aging of the image) at the midpoint of its trip (at the turnaround, 3 years after departure); the Earth sees the image of the ship change from red-shift to blue shift after 9 years (almost at the end of the period that the ...
For endurance events (races of 800 metres or more), the predominant effect is the reduction in oxygen, which generally reduces the athlete's performance at high altitude. [54] One way to gauge this reduction is by monitoring VO 2 max, a measurement of the maximum capacity of an individual to utilize O 2 during strenuous exercise.
The studies support earlier work that found such journeys could significantly damage the brains of astronauts, and age them prematurely. [18] In March 2019, NASA reported that latent viruses in humans may be activated during space missions, adding possibly more risk to astronauts in future deep-space missions. [19]
Required modifications included "adding a lot more oxygen to the spacecraft so that we can feed oxygen to four suits through umbilicals for the full duration of the spacewalk," Gillis said.
Among the different native highlander populations, the underlying physiological responses to adaptation differ. For example, among four quantitative features, such as resting ventilation, hypoxic ventilatory response, oxygen saturation, and hemoglobin concentration, the levels of variations are significantly different between the Tibetans and the Aymaras.

Two days after liftoff, on April 13, 1970, an oxygen tank in Apollo 13’s service module exploded. The explosion crippled the spacecraft, leaving it without most of its oxygen supply, electricity ...
Accelerated aging is testing that uses aggravated conditions of heat, humidity, oxygen, sunlight, vibration, etc. to speed up the normal aging processes of items. It is used to help determine the long-term effects of expected levels of stress within a shorter time, usually in a laboratory by controlled standard test methods .
