Did you know your liver’s size fluctuates significantly throughout the day?

While studying mice, a team of Swiss researchers found that the mice’s liver cells swelled and contracted up to 40% while doing their daily activities. Though research being conducted whether that happens to that extent in humans, one study from 1986 found a person’s liver swells about 20 percent between day and night—presumably related to the fact that the liver is not working as hard when a person is sleeping.
