There is no such thing as the most effective way for the elderly to suffer from motion sickness, which can be prevented by improving the way of traveling in the car and using medications such as theophylline, which are recommended to be used under the guidance of a doctor. “Motion sickness” generally refers to motion sickness, which is a group of uncomfortable symptoms produced by misperception of the state of motion, such as nausea, vomiting, pallor, dizziness, headache and so on. Elderly motion sickness can first be improved by changing the mode of transportation, such as choosing smooth transportation such as moving cars, high-speed trains, choosing the front seat of the car when sitting in the car; when sitting in the car, you can look into the distance, avoid looking at the screen of the cell phone or reading, you can also lean on the seat back to keep your head stable, close your eyes and so on. If the above adjustments do not improve the symptoms of motion sickness, you can use drugs to prevent it before traveling. For example, take antihistamines such as diphenhydramine and theobromine, and apply scopolamine patches behind the ears. Elderly people should consult their doctors before using the above drugs.
