Washington – Researchers at the University of California at Berkeley, in their study published in the latest issue of the Journal of Neurology, have suggested a link between the increase in chronic pain and the increase in Insomnia in modern society.
Initially, Adam Crosse researchers studied the relationship between sleep and pain by conducting experiments on 25 healthy young men in a sleep research laboratory, which were then sent to a research laboratory on sleep, then tested the feeling felt after a night's sleep.
To test the feeling of pain, the researchers raised volunteers by gradually increasing the heat until the participants felt painful. At the same time, they tried to evaluate brain activity in different areas.
During the experiment, volunteers were reminded of their level of pain through a starting point of 1 to 10. The participants felt the heat and considered it uncomfortable to 44 degrees on average. The researchers then repeated the experiment after the participants had spent a night of insomnia.
Most volunteers here began to experience heat pain at an average temperature below 42 ° C.
All volunteers were generally uncomfortable at low temperatures, indicating that their own sensitivity to pain increased after a sleepless night.
Scientists confirm that the injury is the same and the difference of reference is how to estimate brain pain after sleep much less than the human need. This was also observed during the evaluation of observed brain activity, which resulted in increased activity at the brain center responsible for the pain.
At the same time, brain activity decreased in what is called the region of the recombinant nucleus and jaundice, areas playing a role in the relief of pain. "Lack of sleep not only improves the activity of areas that feel pain in the brain, but also blocks natural centers that relieve pain," said Matthew Walker, principal investigator.
Lack of sleep reduces brain activity in what is called the region of the recombinant nucleus and jaundice, areas that are resistant to pain.
"If lack of sleep increases our sensitivity to pain, a good sleep is a natural home that can help relieve pain." In the second part of the study, researchers interviewed 230 men and women on the Internet about the quality of their sleep and the pain they felt the next day.
The evaluation of the results of the investigation confirmed the experiments conducted by the researchers of the laboratory, because it was found that the degradation of the quality of sleep – even if it was low – reflected negatively on the volunteer individually the next day, from where the feeling of pain felt by the volunteer.
The researchers say the study suggests that improving the quality of sleep – even if it is minimal – can help reduce the feeling of human pain.
The researchers found that their findings were particularly important for hospitals that bring together many people suffering from pain and lack of sleep. They predicted that patients' suffering would be reduced if hospitals put more emphasis on improving the quality of their sleep, which could help reduce the amount of painkillers used.
A recent study by neuroscientists at the Polytechnic University of Italy warned that the human brain erodes when people do not sleep enough at night but does not cause any health damage concern.
The researchers monitored the brain of a group of mice to detect the effects of sleep disorders on the brain. The research team observed unusual activity in cerebral astrocytes in sleep-deprived mice, unlike mice that normally slept 7 to 8 hours per night. According to the study, stellar cells, which normally regulate the sleep process, eat synapses in case of lack of sleep.
Dr. Michel Pilsy, co-author of the study, said that synapses feeding on stellate cells were not necessarily harmful because they could constitute brain cleansing.
Lack of sleep stimulates glial cells, he said. The study showed that the persistence of cells in their activity resulted in brain disorders.
Doctors usually monitor the ongoing activity of the brain glia in patients with Alzheimer's disease. Previous research has shown that getting enough sleep at night – seven to eight hours a day – improves the overall health of the body and protects against diseases, especially diabetes and obesity.
Studies have also linked sleep disorders with the risk of stroke, heart attack and weak immune system.
A team of researchers at the University of California has already revealed that sleep deprivation disrupts the ability of brain cells to communicate with each other, resulting in temporary mental deficits affecting memory and visual perception.
