The Influence of Sleep Quality on Chronic Pain

Abstract

Sleep is an essential physiological process that performs the maintenance of several mechanisms inherent to human homeostasis, being considered a healthy sleep, one that has quality and quantity determined to maintain a state of wakefulness during the day. According to the World Health Organization, 30% of the world population has chronic pain. Thus, the objective of this study was to verify the relationship between quality of sleep and chronic pain. This is therefore a field research, carried out via an online form, on pain characteristics and quality of sleep in individuals with chronic pain. The results achieved showed 42 valid answers, with individuals with a mean age of 34.25 (±11.30) years. The average intensity of pain was 4.70 (±2.09), and the quality of sleep was classified as good in 52.28% of the volunteers, although the majority of them slept less than 7 hours per night. Statistically the worse the quality of sleep, the greater the intensity of pain p=0.01, the worse the quality of sleep, the greater the feeling of not having rested, in which p= 0.03 and the worse the quality of sleep, the greater the sleepiness during the day with p= 0.007. We conclude that the greater the
intensity of pain, the worse the quality of sleep of the individuals.
