A video showing the incredible speed of wounds appeared and scientists were amazed to learn that the speed of wound healing was faster than day and night.
Researchers at Cambridge University estimated that recovery would be more likely to occur during sleep, as the body refilled itself. However, their findings actually show an evolutionary advantage with faster recovery during the day, which may open a new medical treatment gate.
Researchers analyzed how different skin cells, known as fibroblasts, react differently to investigate this feature. When infected, fibroblasts migrate to the affected area and produce repair proteins such as collagen, which help to regenerate the damaged tissue. The researchers examined the fibroblasts in the laboratory at different times of the day by drawing the skin cells and followed the healing process under the microscope. The results showed that the cells recovered slower than the ones that were damaged during the day under night conditions.
