A study published in Science Translational Medicine, examined 118 patients at NHS burns units. They found night time wounds took an extra 11 days to heal. As each cell in the body has a biological clock. Our cells have evolved over millions of years, anticipating damage during the day but not at night.
Detailed lab work showed skin cells called fibroblasts were changing their abilities in a 24-hour pattern.
Fibroblasts are the body’s first responders, rushing to the site of injury to close a wound.
During the day they are primed to react, but they lose this ability at night.
