Feeling sick in a car? Here's what may be causing it

Car sickness, an empty stomach, dehydration, too little sleep, heat and chemical fumes can all make you dizzy or nauseous in a vehicle, says Dr Manish Dodmani, gastroenterologist at KIMS Hospitals, Thane. Fumes from solvents can build up in poorly ventilated cars. If you start feeling dizzy, he advises stopping the car and getting some fresh air.
