According to inadequate sleep at night, brain activity increases in pain-sensitive areas and decreases in areas responsible for modulating how painful stimuli are perceived, according to research published on Tuesday.
study published in JneurosciThe Neuroscience Society magazine, led by Matthew Walker of the University of California at Berkeley, suggests The first explanation of the relationship between sleep and pain based on the brain.
These results also help explain Vicious cycle that is created due to lack of sleep due to pain and subsequent cycle of chronic pain and even opioid dependence.
In two studies, one in the sleep lab and the other on the Internet, Walker and his colleagues They demonstrated how the brain treats pain differently when people are deprived of sleep. and how is the quality of this and Pain sensitivity can vary from one night to another.
When researchers prevented young healthy adults from sleeping in the lab at night, they observed increased activity in the primary somatosensory cortex and decreased activity in the striatum and areas of the cerebral cortex during pain sensitivity tests.
In addition, in a study conducted on the Internet, participants reported on increased pain during the dayafter a bad sleep the night before.
“If a sleep deficit increases our sensitivity to pain, as this study shows, sleep should be located much closer to the patient care center, especially in hospital wards,” Walker says.
