Motion sickness, also known as travel sickness or kinetosis, is a condition characterized by a combination of symptoms that occur when there is a discrepancy between the motion sensed by the inner ear and the visual perception of motion. It typically occurs during travel or when exposed to certain types of motion, such as in a moving vehicle, boat, airplane, or amusement park ride.
When we are in motion, our body receives sensory input from various sources, including the inner ear (vestibular system), eyes, and muscles. These sensory inputs are normally synchronized, providing a consistent perception of movement. However, in certain situations, such as when reading in a moving vehicle or looking at a stationary object while on a boat, there can be conflicting sensory information, leading to motion sickness.
The exact mechanisms behind motion sickness are not fully understood, but it is believed to involve a complex interplay between the vestibular system, the visual system, and the central nervous system. The inner ear's vestibular system plays a crucial role in detecting motion and maintaining balance. When there is a mismatch between the information received from the inner ear and the visual system, the brain interprets it as a potential poisoning or intoxication, triggering a range of symptoms.
Symptoms of motion sickness can vary in intensity and may include:
Nausea and vomiting
Sweating
Dizziness and vertigo
Fatigue and drowsiness
Headache etc
