Using the sea and pool post-surgery is planned by taking into account the infection risks and pressure effects during the healing process of the nose.
As the salty nature of seawater can be beneficial for healing the nose, it is permitted starting the 2nd week. However, you must be careful of waves and sudden impacts. You can go into the sea during this period; for activities that raise your heart rate, such as fast-paced swimming, wait until the 1st month has passed.
It is recommended only after the 2nd month because the pool environment carries an infection risk due to chemicals (chlorine, etc.) and potential bacteria buildup.
Due to the high water pressure and the direct pressure the mask will place on your nose, you must avoid diving or snorkeling with a tight mask for 12 months.
