Poor sleep linked to greater pain sensitivity
Poor sleep quality correlates with higher levels of depressive symptoms, greater pain severity, increased fatigue, and greater functional disability in patients with rheumatoid arthritis, according to US researchers.
They suggest addressing sleep problems with drugs or behavioural interventions may have a critical impact on quality of life.
The researchers assessed 162 patients, all of whom had been diagnosed with RA for at least two years.
They said: “Not sleeping well at night can contribute to greater pain sensitivity and fatigue during the day.”
