Avoid smoky environments - e.g. pubs, rooms with open fires. Your tracheostomy opening leads directly to your lungs. Therefore you must make sure that water does not get into your tube. Take a bath instead of shower. There are special shower guards available for those who prefer to shower.
Swimming is only possible with the use of specialised equipment and instruction.
A tracheostomy tube will not prevent you from doing most jobs. Many sports can be continued with a tracheostomy tube in place. Good quality of life with a tracheostomy is not just about looking after your tube. It involves all the other elements that make up a healthy lifestyle e.g. eating well, getting enough sleep, taking exercise, getting out and about and continuing to do the fun things that you enjoy. It is important also that you talk to and include your family, friends and health professionals during this time, so that they can give you the support that you need.
