Study Finds Lack of Sleep Decreases Effectiveness of Vaccines

A new study has found that getting poor sleep could decrease the effectiveness of vaccines, particularly in men. The study, conducted by researchers at the University of California, found that those who slept less than six hours per night had lower levels of antibodies in response to the influenza vaccine compared to those who slept seven or more hours.

The study monitored 164 participants over a two-week period, during which they reported their sleep patterns and received the influenza vaccine. Blood samples were taken before and after the vaccination to test for antibody levels. The results showed that those who slept less than six hours had lower antibody levels after receiving the vaccine, and this effect was more pronounced in men than in women.

While the study did not investigate the reasons why lack of sleep reduces vaccine effectiveness, previous research has suggested that sleep influences the immune system, with inadequate sleep compromising the body’s ability to mount an immune response.

The findings highlight the importance of a good night’s sleep not just for overall health, but also for maximizing the benefits of vaccination. Researchers recommend that individuals prioritize adequate sleep in the lead-up to vaccination to maximize its effectiveness.
