If you've been feeling a little out of sorts ever since updating to iOS 7, you're not alone. For about a week now, users have been reporting vertigo and nausea after using the new Apple interface. Blame those fancy zooming animations when you switch between applications — it's similar to the experience of trying to read in a moving car. Signals to your central nervous system get out of sync when you're focused on a fixed object in the midst of a moving background. That's triggering motion sickness and headaches for some, but not all users.
