Position and Movements
Research:
Vestibular receptors are found in the inner ear next to the cochlea. Notably, they perceive rotational movement (head turn), translations (linear motion), and head tilt in relation to gravity. Consequently, it converts these motions to neural signals that can be transmitted to the brain (Saladin,2020). Further, the Vestibular system, the apparatus of the inner ear involved in balance. The vestibular system consists of two structures; the bony labyrinth of the inner ear, the vestibule, and the semicircular canals, and the structures of the membranous labyrinth contained within them. When the brain interprets the signals differently, it results in motion sickness (Saladin, 2020). Thus, motion sickness occurs when the movement an individual sees is different from what the ear senses (Centers for Disease Control and Prevention., 2022). Further, it is a common disturbance that can occur to every healthy individual. Notably, it is a psychological response to stimuli like air travel, sea, or road. According to CDC, one in every three people get motion sickness at some point, with children between 2-12 years being the most susceptible. Additionally, women pose a risk factor for motion sickness, especially when menstruating, pregnant, or on hormones. Also, individuals using medication and those who get frequent migraines are at risk of contracting motion sickness.

Critical Thinking:
Motion sickness can affect anyone. It is associated with symptoms such as nausea, diarrhea, vomiting, headache, general discomfort, apathy, excessive salivation, warm sensation, and drowsiness. This means that when an individual travels, the disturbance makes them not enjoy their journey. Also, pregnant women will most likely experience motion sickness along the journey. I can relate. I have two children that get severe motion sickness. They can not sit in the back seat. They must sit in the front, or they will be sick every time. To avoid motion sickness, one can keep hydrated by drinking water, avoiding alcohol and caffeine, and reducing sensory input such as closing eyes or sleeping. Further, using distractions such as music and controlling breathing can help individuals.
