Is it OK to exercise the day before rhinoplasty?

Do not exercise the morning of surgery because you run the risk of becoming dehydrated and remember, you can't have anything to drink the day of surgery.

Exercise is considered a healthy activity (when not carried to extremes!).  Yes, after any real surgical procedure, for a time  (days or sometimes weeks) it is important not to overly stress one's body, and to not elevate  blood pressure & heart rate in order to avoid problems. But exercising prior to a procedure should be fine assuming it is a level of activity that one is accustomed to and no dehydration results.  If exercise just prior to a procedure is relaxing and calming, it may actually be a very good thing. But there should also be adequate time to "cool down"  and remain hydrated afterwards so one's body returns to a normal resting state prior to receiving anesthetic drugs and undergoing surgery. Remember that before sedation or general anesthesia, there is an "NPO" (no foods/drinks) time period which your surgeon will order for you.
