After wisdom teeth surgery you should take bed rest for the first day. Lifting things, bending, or any other vigorous activity will result in increased bleeding, swelling, and pain. You should be very careful while going to a standing position from the lying down position. You may feel light-headed when you stand up suddenly from the bed. If you exercise regularly, be aware that your normal fluid and caloric intake is reduced after the surgery. Exercising during the early post-operative period may also result in increased bleeding, swelling and discomfort. So doing exercise should be avoided for 3-4 days following the surgery.
