The official treatment for lasting fatigue, which is now recommended to long Covid patients, is graded exercise therapy
Professor Delaney, a specialist in medical informatics at Imperial College London, used to cycle 80 miles every Sunday, but after he developed long Covid — which is thought to have affected 60,000 people in the UK — even speaking to patients on the phone was a challenge. Sometimes he would feel better, but then he’d relapse.
Three months later, in June, when he’d been able to start working again (though only part-time), he still had brain fog.
The official treatment for lasting fatigue, which is now recommended to long Covid patients, is graded exercise therapy (GET). It involves doing a bit more exercise every day, with NHS website Your Covid Recovery suggesting: ‘It is important that you start being active as soon as possible after discharge from hospital . . . You should aim to build up to 30 minutes of activity at least five days a week.’
For people exhausted by a simple phone call, this seems like a huge task.
This regimen has been prescribed for patients with the long-term fatigue condition known as ME (myalgic encephalomyelitis) or CFS (chronic fatigue syndrome) for nearly 20 years.
However, when these patients complained they felt worse after exercise, they were told it was because they had a faulty belief that they couldn’t exercise. As a result, GET was often combined with cognitive behavioural therapy to rid them of this mistaken idea.
