(a) We know that the legs carry the weight of the body in the normal position due to gravity pull. The astrount in sapce is in weightlessness state. Hence, swollen feet may no effect his working.
(b) In the conditions of weightlessness, the face of the astrount is expected to get more supply. Due to it, the astrount may develop swollen face. As eyes, ears, nose, mouth etc. are all emnedded in the face, hence, swollen face may effect to great extent the seeing/hearing/smalling/eating capabilities of the astrount in space.
(c ) Headache is due to mental strain. It will perist whether a person is an astrount in space or he is on earth. It means headache will have the same effect on the astrount in space as on person on earth.
(d) Space also has orientation. We also have the frames of reference in psace. Hence, orientational problem will affect the astronaut in sapce.
