March 14, 2023 – Do you need to achieve maximum protection through vaccinations? Then it's best to sleep not less than 7 hours before and after the vaccination, as a brand new study recommends.
Compared to individuals who slept not less than 7 hours, individuals who slept lower than 6 hours in the times surrounding a vaccination produced significantly fewer antibodies that recognize and kill viruses and bacteria within the body.
Because the effectiveness of many vaccines wanes over time, the booster essentially makes the protection from the vaccine last more — by as much as two months, the researchers found.
“Good sleep not only enhances the protective effect of the vaccine, but can also prolong it,” said researcher Eve Van Cauter, PhD, professor emeritus on the University of Chicago, in a opinion.
The study, which was published on Monday in Current Biologyre-analyzed previous research on the link between sleep and the effectiveness of vaccines against flu and hepatitis. The researchers sought to grasp the connection because there was evidence that folks developed different levels of immunity after receiving the identical COVID-19 vaccines. Sleep studies specifically on COVID vaccines are usually not yet available, so the researchers decided to guage existing studies and extrapolate those findings to what is understood about COVID vaccines.
“The way we stimulate the immune system is the same whether we use an mRNA vaccine for COVID-19 or a flu, hepatitis, typhoid or pneumococcal vaccine. It's a prototypical antibody or vaccine response, and that's why we think we can generalize it to COVID,” said researcher Michael Irwin, MD, a UCLA expert who focuses on the connection between psychological processes, the nervous system and immunity.

When researchers checked out vaccine response in numerous groups, the results of sleep were best in men and in people ages 18 to 60. Researchers said more research is required on the results in women because fluctuations of their hormone levels affect the immune system.
They also found that the vaccine's effectiveness was not as affected by lack of sleep in people aged 65 and over. The authors suspect that it's because older people sleep lower than younger people anyway.
The findings are vital because they provide people a chance to alter their very own behavior to enhance their health and immunity, Van Cauter said.
“If you look at the differential protective effects of the COVID-19 vaccines, you see that people with underlying health conditions are less protected, men are less protected than women, and obese people are less protected than people without obesity,” she said. “These are all factors that are beyond the control of the individual, but you can influence your sleep.”
