在太空飞行中,人体生理系统为适应失重环境而发生一系列的改变,除骨丢失和肌萎缩随飞行时间延长逐渐加重外,大部分生理系统的变化会达到新的平衡。然而,您知道吗?当航天员由太空返回地面后,健康也面临着诸多挑战。这是因为机体从太空的失重环境中进入地球的重力环境中会产生诸多不适,将有一个逐步适应和恢复的过程。 In space flight, the human physiological system to adapt to a series of changes in weightlessness environment, in addition to bone loss and muscle atrophy with flight time gradually increased, most physiological changes will reach a new balance. However, did you know that when astronauts return to the ground from space, health faces many challenges. This is because the body will have a lot of discomfort from entering the gravity environment of the Earth from the weightless environment of space, and there will be a gradual process of adaptation and recovery.
