In a study published in the Journal of Pain Research, Chinese researchers investigated the relationship between sleep quality and the prevalence of pain, reports Medical News Bulletin.

Most laboratory-based pain research has focused on pain sensitivity or acute pain tolerance, while epidemiological studies have primarily focused on the link between poor sleep quality and the risk of experiencing pain, not its effects on pain intensity. Few studies have investigated the association between sleep quality and pain intensity within the general population.

Chinese researchers recently performed a cross-sectional survey to shed light on sleep quality in a sample of rural Chinese adults and its association with prevalence of pain. They also examined the influence of sleep quality, associated psychosocial variables, and health status on pain intensity among the general population in everyday settings. They published their results in the Journal of Pain Research.
