How to deal with children's dizziness

Have you ever felt dizzy? Do you know why we feel dizzy? One type of dizziness (vertigo) is the illusion of movement or motion hallucination of the surrounding environment caused by spatial positioning disorder. This feeling comes from our vestibular system.

Vestibular system

The human vestibular system can be divided into three parts: the peripheral vestibular system, the vestibular central system and the motor output system. The peripheral vestibular system is located in our inner ear. The vestibular receptors are composed of the semicircular canals, the utricle and the saccule. The vestibular receptors can sense the rotation of the human head and the linear acceleration movement. After the information is processed by the nerve center, it will be output to the human body: gravity sensing, head orientation perception, control of eyeball rotation and posture control. At the same time, the vestibular center can also process proprioception, vision, hearing, etc. The vestibular center is a more comprehensive sensory center of the human body.

Q: What role does the vestibular system play in a child’s development?

Answer: Within 15 months after birth, all learning is centered on vestibular development, which is the child's pathway into consciousness. Moreover, important early developments such as balance, autonomous movement, language discrimination, and vision and motor coordination all rely on vestibular sense.

Early vestibular development

From the fetal period, the vestibular system of children develops very rapidly. It is the first to mature in the human sensory system. From the 10th to 11th week of gestation, the baby begins to move and can feel gravity. At about 5 months of pregnancy, the fetus can feel the mother's body movements. In the neonatal period, as the vestibular system matures further, the baby's posture gradually appears with the age of the month: the development of large movements such as raising the head, stretching, turning over, and sitting up.

The function of vestibular sense in childhood

In the early days after birth, vestibular sense helps children feel and adapt to changes in gravity, and promotes the development of early primitive reflexes and postural control.

The vestibular sense can receive and filter the visual, auditory, olfactory and tactile sensory information directly in front of the head, so that the brain can obtain more appropriate sensory input and reduce the brain's sensory processing pressure.

Vestibular sense is the key to maintaining human balance. The human body senses spatial position through vestibular sense and makes movements to maintain body balance. There are three senses involved in human balance: vestibular, proprioceptive and visual. When there is a lack of coordination in the transmission of the three senses, the human body will feel dizzy. At this time, the vestibular sense needs to be adjusted to restore the body's balance.

The vestibule is also related to the control of eye movement. Among the eye functions, basic functions such as tracking, maintaining vision, and maintaining attention during movement are closely related to the vestibule. Advanced functions such as attention, reading and learning, and imitation ability are inseparable from the vestibular sense.

Vestibular sense is a very important sense for children and plays an indispensable role in their early development. Child caregivers should pay attention to the time of vestibular activities during childhood to promote the development of children's vestibular abilities.
