Scientists proved that a ten-hour night sleep increases concentration and reduces pain sensitivity.
The study involved 18 healthy volunteers who were divided into two groups.
For 4 nights members of one group slept as much as they used to and members of the other group – for 10 hours. For an objective assessment of daytime sleepiness, the scientists used multiple test latency to sleep, pain sensitivity – thermal radiation.
The results obtained indicate that members of the second group slept every night for 2 hours more, than members of the first group. This has led to an increase in concentration and decrease in pain sensitivity. After the end of the research, participants of the second group could hold their finger on the source of thermal radiation 25% longer than before. This reflects the reduction to pain sensitivity.
“We were able to show that prolonged sleep plays an important role in the treatment of diseases associated with chronic pain, as well as in preparation for operations. It’s amazing that a night’s sleep has a significant impact on pain sensitivity. “, – says Timothy Rogers, the author of the study.
