The spoon theory was introduced by Christine Miserandino in her essay The Spoon Theory, which is posted on her website But You Don’t Look Sick.
Christine created a disability metaphor that explains the reduced amount of energy available for activities of daily living and productive tasks that may result from disability or chronic illness. Spoons are an intangible unit of measurement used to track how much energy a person has throughout a given day. Each activity requires a given number of spoons, which will only be replaced as the person “recharges” through rest. A person who runs out of spoons has no choice but to rest until their spoons are replenished.
Spoons suddenly look important to you through this view on life with a chronic illness. Hopefully it will help people understand each other better.
