A method of determining a route in a navigational system, the method comprising: determining, for each of a plurality of different routes to said destination S104, a probability of motion sickness of a vehicle occupant S106. The route may then be selected based on the probability of motion sickness. The probability of motion sickness may be based on the motion profile of the route, which is based on the likely motion of the vehicle. A speed profile based on the likely speed of the vehicle may be determined, wherein the speed profile is determined based on speed limits, real time traffic data (including the actual speed of vehicles), the presence of junctions on route and/or historic data based on the driving profile of the driver. An indication of a route exceeding a threshold value of probability of motion sickness may be provided. The probability of motion sickness may be determined in dependence on physiological data such as heart rate data, heart rate variability data, heat flow through the vehicle occupant’s skin, temperature data, image data, or whether the occupant is asleep S114. Telematics data may be used to determine the probability of motion sickness for a plurality of segments along a route, and a remedial action such as selecting a different lane to ravel, increasing the radius of a turn, travelling at a slower speed or stopping applied if the probability of motion sickness for a segment is above a threshold value.
