Lack of sleep makes a person more susceptible to pain

This conclusion was made by scientists from the California Institute in Berkeley, having conducted a series of experiments. The first experiment was attended by 24 volunteers. None of them had any sleep problems or pain disorders. To begin with - using functional MRI and exposure to heat - the scientists measured the pain threshold of each participant, after which the volunteers were asked to spend two nights in the laboratory. The first night is a full eight-hour sleep, the second is a complete lack of sleep.

After each night, scientists conducted a heat test - a special device was applied to the feet of the participants, the temperature of which gradually increased. As a result, it turned out that sleepless night significantly lowered the pain threshold of the participants. Due to lack of sleep, they called those temperatures painful that they had not considered unpleasant a day ago.
