weightlessness

Etymology: AS, gewiht + ME, les

a state of absence of apparent weight, as in being beyond the effects of gravitational force in space travel. See also space medicine.

Weightlessness

A state in which there is no gravitational effect on a body or material
Physiologic effects Bone mineral loss, altered blood chemistries, weakened immune system, variable heart rate, arrhythmias, loss of skeletal and cardiac muscle mass and strength, increased urinary loss of nitrogen and phosphorus, motion sickness, and redistribution of fluids that are normally pooled in the lower torso and legs, resulting in a ‘fat face’

weightlessness

in horses induces osteoporosis if the period of weightlessness is long enough; in dogs the effects of weightlessness are confused with those of head-out immersion in water.
