Anxiety impedes our balance. Anxiety can make you feel dizzy for no apparent reason.
You might even stumble as you’re walking or experience blurry vision. During these dizzy spells, it can be helpful to close your eyes, breathe in slowly through your nose and wait a little while before resuming your activities.

Anxiety alters our sense of smell.

When we’re anxious, every smell and scent seems unpleasant, no matter how good they normally are to us. The olfactory system becomes more activated, so we’re capable of perceiving unpleasant smells around every corner.
