Scientists find daytime wounds heal more quickly

The antidote to a bad scrape-up is usually a fairly simple recipe: antibiotics, bandages, and time. Now, a new study suggests that timing also matters. Skin cells that help patch up wounds work more quickly in the daytime than they do at night, thanks to the workings of our circadian clock. The finding suggests patients might recover from injury more quickly if they have surgery during the right time of day.
