If you’re scheduling an appointment for a vaccination — whether for Covid-19, the flu or for travel to another country — make sure you’re getting a long, restful night’s slumber before you head to the doctor.
Sleeping less than six hours the night before you get the shot may limit your body’s response to the vaccine, reducing protection against the virus or bacteria, according to a new study.
“Good sleep not only amplifies but may also extend the duration of protection of the vaccine,” said senior author Eve Van Cauter, professor emeritus at the University of Chicago’s Department of Medicine, in a statement.
