Bed rest

Bed rest, also referred to as the rest-cure, is a medical treatment in which a person lies in bed for most of the time to try to cure an illness. Bed rest refers to voluntarily lying in bed as a treatment and not being confined to bed because of a health impairment which physically prevents leaving bed. The practice is still used although a 1999 systematic review found no benefits for any of the 17 conditions studied and no proven benefit for any conditions at all, beyond that imposed by symptoms.

In the United States, nearly 20% of pregnant women have some degree of restricted activity prescribed despite the growing data showing it to be dangerous, causing some experts to call its use "unethical".
