Progressive relaxation is the gradual and conscious letting go of built-up tension in the body’s muscles.
If you are unwell or recovering from an illness or surgery you can practice this form of relaxation in bed or in an easy chair.
When you have become more confident you will be able to practice it yourself whenever you feel tired, anxious or otherwise stressed. This technique is best done in a quiet place for 10 to 20 minutes where you won’t be interrupted.
