Symptoms
Symptoms include fatigue, dizziness, facial paleness, cold sweat, nausea and vomiting.
Cervical ailments, high blood pressure, high cholesterol and diabetes could induce airsickness. Airsickness is very common among the old and the infirm.

Cause
Speed changes and air turbulences could result in irregular bumps, causing the body to produce sensitivity reactions.

Recommendations
Don’t travel by air with an empty stomach – hunger could exacerbate airsickness instead of alleviating it. In about half an hour before take-off, you can take some anti-airsickness medicines as advised by a doctor.
During flight, have a paper bag ready. Choose to sit in the central part of the cabin which is relatively stable.
If symptoms appear, adjust the seat back to the lying position, remain motionless, and take deep breaths, eyes closed.
