Do pretzels help with car sickness?

Pretzels do not have any scientific evidence to suggest that they can help with car sickness. Car sickness is caused by motion-induced nausea, which leads to symptoms like dizziness, vomiting, cold sweats, and headaches. Pretzels, being a type of salty snack, may provide some temporary relief from nausea or discomfort due to their salty flavor, but they are not a proven remedy for car sickness.
