On March 13, was published in current biology an investigation what I achieve by proving that less than 6 hours of sleep affects the effectiveness of vaccines. As explained, people who sleep 7 or more hours produce more studies.
The study carried out by teams from the Chicago Universities (USA) and the university of lyon (France) reviewed the relationship between sleep and the body’s response to vaccination. The results were achieved by comparing seven on the body’s immune response of people who slept 7 hours a night, against those who slept 6 or less. Thus they were able to determine that less than 6 hours of sleep a night causes a sharp decrease in the immune response.
The researchers took as parameters the responses of flu vaccine and hepatitis A and B. Although the study did not focus on the COVID vaccine, the experts explained that the response to this vaccine can also be “improved” with simple behaviors such as sleeping better and more hours.
Krike Spiegel, university of lyonhighlighted that: “Interestingly, we observed the same results in both influenza, which is a respiratory virus, and hepatitis, which affects the liver, suggesting that this effect could extend to all types of viruses, including coronaviruses such as SARS-CoV-2”.
Although there are still aspects to be studied, according to this research certain behavioral responses, such as sleeping well, could improve the efficacy of vaccines and, also, the results of a successful vaccination process that mitigate the advance of a pandemic.
However, the researchers also clarify that large-scale studies are necessary to define the time window before and after vaccination, where optimize sleep duration could benefit from the response of the studies.
The results of the report
Another interesting aspect of the study is the differential response between men and womenwhere they came to the conclusion that in the women there is not such a direct relationship between hours of sleep and the response to vaccines.
So, for the men the relationship “more sleep, better effect” is more solid. It was simply made that the men who slept better and more hours had a higher production of tests. However, in women the relationship was not as direct and probably also accounted for fluctuating hormone levels.
“In women, immunity is influenced by the status of the menstrual cycle, contraceptive use, and by menopause and postmenopausal status, but unfortunately none of the studies we summarized had data on sex hormone levels,” she said. Krike Spiegel about
