In the previous century, bedrest was often used as a therapy by itself.¹ The ancient Greeks prescribed it, as did clinicians in the late 19^th century until the Second World War. Back then, a myocardial infarction required patients to lie down for four weeks.

The logistic challenges of the Second World War changed the paradigm. Hospitals full of wounded soldiers had to make room for the most wounded, thus mobilising patients earlier than usual. Clinicians noted that this improved outcomes. Additionally, studies carried out in preparation for space missions demonstrated muscle loss and functional decline in immobile subjects. Since then, detrimental health effects of immobilisation have been reported for almost any organ in the human body.^2-4 Myocardial damage, postural hypotension, atelectasis, higher rate of pulmonary and urinary tract infections, thrombosis, sarcopenia, reflux disease, constipation, diverticulitis and numerous other effects are associated with prolonged bedrest.

This insight has shaped current practice: the use of physiotherapists and enhanced ambulatory care are examples of measures implemented throughout modern medicine. However, while the importance of mobilisation is undeniable, health institutions are still designed primarily around the bed. Further measures, for example altered ward designs, may be introduced to promote patient mobility and further reduce adverse health effects in an increasingly sedentary, obese and aging society.
