New findings: Your wounds heal faster in the daytime than at night

Research by British scientists shows that wounds often have a faster rate of healing in the daytime, contrary to the previous view that nighttime is the best time for the body to heal wounds.

We often believe that night sleep works to heal and restore wounds faster, because the function of sleep is to help recharge energy and treat body wounds. However, perhaps everything is not exactly the way we always imagined.

In fact a study has shown, the body's healing process is accelerated faster during the day instead of night.Caused by the way the body's circadian rhythms control cell activity .

The process of healing the body's wounds is accelerated faster during the day instead of at night.

We often think that the circadian rhythm is controlled by a "clock" located in the hypothalamus of the brain. But scientists now discover that human circadian rhythms are controlled by all the cells in the body.

Last year, researchers at the University of Cambridge in England tested how skin cells called fibroblasts react with time during the day or night. When we are injured, fibroblasts usually move to the wound site and create collagen-like recovery proteins, thereby helping to regenerate damaged tissue.

However, this reaction also depends on a protein called actin. if there is not enough actin, the fibroblasts' ability to move will be limited. But how to determine when the amount of actin is the most?

According to Sciencealert, researchers later discovered actin levels depending on the human's day and night circadian rhythms. They tested cell fibroblasts on a petri dish (a glass or cylindrical plastic disk with a lid that is often used for cell culture). The group later found that fibroblasts often move and regenerate wounds faster in the daytime than at night.

Later experiments on mice also yielded similar results. Their wounds heal faster at day time.

John O'Neill, research author and molecular biologist shared: "We are consistent with observations of double differences related to the rate of healing of wounds between day and night of the body. In both cells and mice, we can fool cells that are now daytime to speed up tissue recovery, for example, we can turn on the lights at night and turn off at other times. each other during the day ".

Scientists believe that this study plays a huge role in the development of medical treatments, helping surgeons adjust the healing time to provide the best recovery effect. .

When the research team analyzed clinical data from patients suffering from burn injuries, they found a significant difference in the results of treatment.

It is difficult to determine why the body's healing process occurs more quickly in the daytime.

Nocturnal burns (prescribed between 8:00 am and 8:00 am) usually take an average of 60% longer to heal than burns during the day. In particular, a person who burns at night takes up to 28 days to recover and the person who burns during the day only takes 17 days to heal. In that level of burns between the two groups of patients are the same.

A sufficiently large gap between research results shows the potential for developing treatments based on human circadian rhythms.

It is difficult to determine why the body's healing process occurs more quickly in the daytime. However, some researchers speculate, that may be how the human body adapts to evolution. The body's ability to heal faster during the day is more likely because this time is when we have to exercise the most and also get more easily injured.

The findings of British scientists have been published in the journal Science Translational Medicine.
