What if you have motion sickness or a stuffy nose?
If you are seasick, then you need to breathe deeper and warn the instructor about this so that he does not make sharp maneuvers under a parachute.
If you have a stuffy nose, follow these simple steps: hold your hand over your nose, close your mouth tightly, exhale, open your mouth. Perform the same steps during takeoff or after opening the canopy if you feel any discomfort. They will help compensate for the pressure. Also, if you have a runny nose, be sure to rinse your nose well with vasoconstrictor drops before jumping.
