Scientists say that long-term space travel can make people shorter, fatter, and uglier.
British astrobiologist "Dartnell" revealed that in the weightless environment of space, the human body's bones and muscles cannot develop normally. Additionally, in a constant-temperature state with a lack of exercise, people become shorter and weaker.
Furthermore, weightlessness causes bodily fluids to shift upward, accumulating in the skull, making the head appear perpetually swollen and disproportionate. The constant temperature also means the body sweats less, reducing the need for hair to retain warmth or eyelashes to block dust. Ultimately, humans might evolve into hairless, short, big-headed, and unattractive creatures.
