Researchers led by University of California-San Francisco found that sleep duration is directly tied to vaccine immune response and sleeping for less than six hours can reduce the effectiveness of vaccines taken by the body.
To explore whether sleep duration, sleep efficiency, and sleep quality assessed at home and not in a controlled sleep lab would impact immune processes important in the protection against infection, the researchers investigated the antibody response to hepatitis B vaccinations on adults in good health.
The study involved 125 people, 70 women and 55 men between the ages of 40 and 60. All were nonsmokers in relatively good health, and all lived in Pennsylvania
