All About Adolescence. Adolescence describes the teenage years between 13 and 19 and can be considered the transitional stage from childhood to adulthood. However, the physical and psychological changes that occur in adolescence can start earlier, during the preteen or tween years (ages 9 through 12). Adolescence can be a time of both disorientation and discovery.
You get motion sickness when one part of your balance-sensing system (your inner ear, eyes, and sensory nerves) senses that your body is moving, but the other parts don't. For example, if you are in the cabin of a moving ship, your inner ear may sense the motion of waves, but your eyes don't see any movement.This conflict between the senses causes motion sickness. You may feel sick from the motion of cars, airplanes, trains, amusement park rides, or boats or ships.or example, if you are in the cabin of a moving ship, your inner ear may sense the motion of waves, but your eyes don't see any movement.

Motion sickness is due to irritation of a portion of the inner ear called the labyrinth. The symptoms of motion sickness include nausea, vomiting, and vertigo. Other common signs of motion sickness are sweating and a general feeling of discomfort and not feeling well (malaise). Symptoms usually stop when the motion that causes it ceases.
