Space adaptation syndrome Space adaptation syndrome (SAS) or space sickness is a condition experienced by around half of space travelers during adaptation to weightlessness. It is related to motion sickness, as the vestibular system adapts to weightlessness.

Dizziness and Motion Sickness Dizziness can be described in many ways, such as feeling lightheaded, unsteady, giddy, or feeling a floating sensation. Vertigo is a specific type of dizziness experienced as an illusion of movement of ones self or the environment. Some experience dizziness in the form of motion sickness, a nauseating feeling brought on by the motion of riding in an airplane, a roller coaster, or a boat. Dizziness, vertigo, and motion sickness all relate to the sense of balance and equilibrium.

The effects of space travel on the human body Being in space is like standing on your head; fluids tend to pool in the upper part of your body, giving you a swollen face. It is similar to when your ankles swell on a long-duration flight because fluid pools in your feet. “Your body preferentially drives fluid towards the upper part of the body,” explains Fong.

Weightlessness Weightlessness, condition experienced while in free-fall, in which the effect of gravity is canceled by the inertial (e.g., centrifugal) force resulting from orbital flight. The term zero gravity is often used to describe such a condition. Excluding spaceflight, true weightlessness can be experienced only briefly, as in an airplane following a ballistic (i.e., parabolic) path. Crews of spacecraft are subject to the problems of weightlessness. It was learned from early Soviet and U.S. manned missions that there is a reduction in heart and respiration rates and a progressive loss of body weight and bone calcium during flights of relatively short duration.

Space charge and space charge effect Space charge refers to the collection of electrons which are emitted from the metal surface, after the application of tube current, at a short distance away from the metal surface. These electrons collect and form a cloud of charge around the metal surface. This space charge limits the further emission of electrons from the surface and is referred to as space charge effect.

Medical Definition of Motion sickness Medical Definition of Motion sickness. Motion sickness: A disorder of the sense of balance and equilibrium and, hence, the sense of spatial orientation that is caused by repeated motion such as from the swell of the sea, the movement of a car, or the motion of a plane in turbulent air. Motion sickness is due to irritation of a portion of the inner ear called the labyrinth.

Motion sickness Motion sickness or kinetosis, also known as travel sickness, is a condition in which a disagreement exists between visually perceived movement and the vestibular system 's sense of movement. Depending on the cause, it can also be referred to as seasickness, car sickness, simulation sickness or airsickness.Dizziness, fatigue, and nausea are the most common symptoms of motion sickness. Sopite syndrome, in which a person feels fatigue or tiredness, is also associated with motion sickness.Nausea in Greek means seasickness (naus means ship). If the motion causing nausea is not resolved, the sufferer will usually vomit.Vomiting often will not relieve the feeling of weakness and nausea, which means the person could vomit until the cause of the nausea is treated.ausea in Greek means seasickness (naus means ship). If the motion causing nausea is not resolved, the sufferer will usually vomit. Vomiting often will not relieve the feeling of weakness and nausea, which means the person could vomit until the cause of the nausea is treated.

About Motion Sickness Some people can get nauseous even thinking about take-off on a plane or boat. Motion sickness happens when the inner ear, the eyes, and the deeper tissues of the body’s surface, called proprioceptors (pronounced proh-pree-uh-sep-ters), send conflicting signals to the brain.

- 1 Do not read while traveling if you are prone to motion sickness. 2  When traveling by car or boat, it can sometimes help to keep your gaze fixed on the horizon or on a fixed point. 3  Open a vent or source of fresh air if possible.otion sickness, sometimes referred to as sea sickness or car sickness, is a very common disturbance of the inner ear that is caused by repeated motion. Anyone can develop motion sickness, but people vary in their sensitivity to motion.

- Decompression sickness describes a condition arising from dissolved gases coming out of solution into bubbles inside the body on depressurisation. DCS most commonly refers to problems arising from underwater diving decompression, but may be experienced in other depressurisation events such as emerging from a caisson, flying in an unpressurised aircraft at altitude, and extravehicular activity from spacecraft. DCS and arterial gas embolism are collectively referred to as decompression illness. Si

Space adaptation syndrome As with sea sickness and car sickness, space motion sickness symptoms can vary from mild nausea and disorientation, to vomiting and intense discomfort; headaches and nausea are often reported in varying degrees. About half of sufferers experience mild symptoms; only around 10% suffer severely.
