Medical Video: How a wound heals itself - Sarthak Sinha
A study showed that the time of injury turned out to have a relationship with the speed of wound healing. The wounds that occur during the day will recover faster than at night. See what causes the wound to heal faster in the following afternoon.
Is it true that wounds that appear during the day heal faster?
A study examined this in cells grown in the laboratory. These cells come from fibroblast cells taken during the day and night. As a result, cells taken during the day regenerate faster than those taken at night.
Not only in the laboratory, the same effect is also seen in humans. The human study analyzed the relationship between the time of injury and the length of wound healing. Samples were taken from medical records of burn unit units in England and Wales aged 18 to 60 years. The total sample in this study amounted to 118 patients, after taking samples that had other illnesses or skin grafts.
As a result, burns that occur at night require a longer recovery time than injuries that occur during the day.
Injuries that occur at night (8 o'clock at night to 8 am) require 28 days to recover 95 percent.
Meanwhile, wounds that occur during the day (8am to 8pm) only need 17 days to recover 95%.
Therefore, it can be interpreted that wounds during the day recover 11 days faster than at night. This difference is quite significant, considering that the wounds that occur during the day are 60 percent faster than wounds that occur at night.
How did it happen?
Every living thing has a body's biological clock called the circadian rhythm. This biological clock regulates all kinds of functions of the human body every day, for 24 hours.
Well, the biological clock turns out to be owned by every cell in the body. Each cell contains a special gene with the term "time gene". The gene will regulate different cell activity every time, in a span of 24 hours.
The researchers found that during the day, there was an increase in protein activity that improved and moved cells, especially actin proteins. Collagen, one of the proteins that make up the skin, is also more common in wounds that occur during the day.
That's why if you experience an injury or trauma during the day, there is a high chance that the wound will heal faster. However, how fast the recovery of one's wounds depends on many things. Not only at the time of the incident. There are factors such as how well you clean the wound, how big or in the wound, etc.
If the wound heals faster, the risk of infection will decrease
Of course this discovery has a positive impact on the medical world. With wounds that heal faster, the risk of infection will decrease. The occurrence of excessive scars will also decrease with this knowledge.
This new knowledge can also be applied when determining the schedule of surgical operations. Actions of surgery that are in accordance with one's body clock will speed up the recovery period, so that patients can return to their activities faster and have a minimal risk of complications or infections.
However, more research is needed to find out more about the relationship of the circadian rhythm, aka the body's biological clock with the speed of recovery in humans.
