Bad Sleep Might Make Vaccines Worse
Sleep can affect our biology in both major and subtle ways. Case in point, a 2023 study found that sleeping fewer hours a night immediately before and after getting a vaccine was associated with having lower levels of vaccine-related antibodies—in other words, weakening our body’s immune response to whatever germ the vaccine is meant to target. Some past studies have yielded contradictory results, so more data might be needed to settle whether this link is genuine. But research in general does point to sleep being crucial for a healthy immune system.
