The research, published in the journal Current Biology concluded that getting good sleep also helps human immune systems response to vaccinations.

The study also says those who get less than 6 hours of sleep produce fewer antibodies as well as for those who sleep for 7 hours or more produce significantly more antibodies, and this decrease is similar to the diminishing of antibodies of the “Corona” virus, two months after getting vaccinated.

The study’s lead author, Dr. Karen Spiegel of the French National Institute of Health and Medicine in Lyon, and colleagues first combined and re-analysed the results of seven studies that involved vaccinating people against influenza and hepatitis A and hepatitis B.

Next, the researchers compared the antibody responses of individuals who slept 7 to 9 hours per night (the recommended level for healthy adults) and those who slept less than 6 hours per night.

In general, they found supportive evidence that sleeping less than 6 hours each night reduces the immune response to vaccination, and when they analysed the data of men and women separately, the result was significant only in men, noting that the effect of sleep duration on antibody production was more variable in women. .

Scientists also discovered that the negative impact of insufficient sleep on antibody levels was greater in adults, between the ages of 18 and 60, compared to people over the age of 65.

The study suggests that knowing how sleep affects vaccination may give people a certain degree of control over their immunity.
