Depending on what time it is, your body responds differently to an injury or infection. During the day, you're likely to heal faster and fight infection better than at night. And historically, scientists weren't entirely sure why. That picture is starting to clear up thanks to a new study published last week in the journal
Science Immunology. The research finds a missing piece of the puzzle in neutrophils, powerful immune cells that — despite living less than 24 hours — know the difference between day and night.
