10 Ways Motion Sickness Could Indicate Serious Health Problems
1. Treatment

Although motion sickness usually stops when the repetitive motion ceases, some people experience symptoms for hours or even days later. Looking out the window of a moving vehicle may help reduce symptoms by reaffirming visual motion. Taking a nap or closing the eyes may also help prevent psychogenic effects, as well as chewing gum. Medications such as antihistamines and nervous system blockers are available in pill or patch form. Getting fresh air or focusing the eyes on an object straight ahead may also help.
