Washington – Researchers at the University of California at Berkeley, in a study published in the current issue of the Journal of Neurology, suggested a link between increased chronic pain and increased insomnia in modern society.
At first, Adam Crosse students studied the relationship between sleep and pain through experiments on 25 healthy young men in the sleep lab. They sent volunteers to the sleep lab, and then tested how much they felt in sleeping in the lab.
To test pain, scientists raised volunteers by gradually increasing heat until the participants felt painful. At the same time, they tried to judge the brain in different areas.
During the experiment, the volunteers were reminded of their pain levels, starting at 1 and ending at 10. The participants felt warm and on average considered it unpleasant at 44 degrees. Researchers then repeated the same experiment after the participants had spent the night of insomnia.
Here most volunteers began to entertain at low temperatures, averaging 42 degrees.
All volunteers were generally uncomfortable at low temperatures, indicating that their own sensitivity to pain increased after spending the night without adequate sleep.
Scientists confirm that the injury is the same and the reference difference is how to estimate the pain in the brain after sleep much less than the need for a person. This was also observed in the evaluation of observed brain activity that increased activity in the middle of the brain responsible for the pain.
At the same time, brain activity has decreased in what is known as the region of the recombinant nucleus and jaundice, areas that play a role in overcoming pain. "Lack of sleep not only increases the activity of areas that experience brain pain but also blocks natural pain relieving centers," said Matthew Walker, lead researcher.

"If the lack of sleep increases our sensitivity to pain, good sleep is a natural home that can help relieve pain." During the second part of the study, researchers surveyed 230 men and women over the Internet about how good their sleep was, and how painful they felt the following day.
The results of the survey were confirmed by experiments carried out by lab researchers because it was found that the drop in quality of sleep – even if the decrease was small – negatively reflected on the volunteer individually the next day when the feeling of voluntary pain.
Researchers say the study positively suggests that improving sleep quality – albeit only minimally – can help reduce human pain.
Researchers have found that their findings are particularly important for hospitals that combine many people who suffer from pain while suffering from sleep deprivation. They predicted that patients' suffering would be reduced if hospitals were better focused on improving the quality of sleep, which could help reduce the amount of pain medication used.
A recent study of neuroscientists at the Polytechnic University in Italy warned that the human brain is getting worse when people do not get enough sleep at night but do not cause unhealthy health damage.
Scientists have been monitoring the brains of a group of mice to see the effect of sleep disorders on the brain. The research team observed unusual activity in cerebral astrocytes in sleepless mice, unlike mice normally sleeping from 7 to 8 o'clock in the night. Stellar cells that normally regulate the process of sleep are synapses in sleep deprivation, according to the study.
Dr. Michel Pilsy, co-author of the study, said the star cell liver synapses were not necessarily harmful because they could be brain cleansing.
Lack of sleep stimulates glial cells, he said. The study has shown that persistence of cells in their activity, at low speed, leads to brain disorders.
Physicians usually monitor sustained activity in the glia brain in patients with Alzheimer's disease. Previous research has found that sleeping in sufficient amounts at night – seven to eight hours a day – improves overall body health and protects against illnesses, particularly diabetes and obesity.
Studies have also linked sleep disorders to the risk of stroke, heart attack and weak immune system.
A team of researchers at the University of California previously revealed that sleep depression is interfering with the ability of brain cells to communicate with each other, leading to temporary mental deficits that affect memory and visual perception.
