Sleep loss activates cellular inflammatory signaling.

Randomized Controlled Trial

Human

2008 Sep 15

This study found that staying up from 11 PM to 3 AM makes your immune cells more active in causing inflammation, but it doesn’t change how many of each type of immune cell you have. So the inflammation isn’t because you have more of certain cells—it’s because the cells you already have are working harder.

Similar Assertions

When you don’t get enough sleep for just a short time, your body’s immune cells become more active in a way that triggers inflammation, which might raise your risk for diseases like heart disease, arthritis, and diabetes.

When you only get 4 hours of sleep, your body’s immune cells get activated in a way that causes inflammation, and this happens even if your stress hormone levels don’t change.

Skipping sleep from midnight to 3 a.m. one night can spike a key inflammation signal in women’s blood cells by about 30%, but not in men—meaning sleep loss might affect women’s bodies differently at a cellular level.

When people don’t get enough sleep, women’s bodies show a stronger immune reaction than men’s — specifically, a key inflammation signal called NF-κB turns on in women but stays quiet in men.
