The researchers recorded on video the long process of wound healing in humans. It turned out that in the daytime it is much more quickly than in the night.
Scientists from Cambridge University have decided to record the process of wound healing, which usually takes a few days. This video shooting was conducted almost non-stop, and this interesting experiment has allowed to come to surprising insights, unexpected for its authors. It turned out that the rate of wound healing by day much higher than by night. Science believes that the wounds on our body are tightened under control of a special “master clock” of the brain. But scientists who carried out observations, it was expected that the healing process will be activated at night when the body rejuvenates and passes through “overcharging”.
The greater was their surprise when a video recording showed that it was the day the healing takes place as quickly as possible. Scientists explain the findings of experiment an evolutionary advantage – the fact that in daylight the wounds heal faster just because day, we more often get. The observations also open up opportunities for the development of more effective treatment or, for example, building schedule surgery so that the patient recovering from them as quickly as possible.
The attention of researchers was attracted by skin cells called fibroblasts, to take an active part in the healing of wounds. Their reaction turned out to be different depending on the time of day. Fibroblasts are dependent on a protein called actin, which is fueling their movement to the place of damage. Scientists believe that actin is also affected by day and night time. (READ MORE)
