Night sweats after the COVID-19 vaccine. Where do they come from?

Regardless of whether the vaccinated person has received Pfizer, Moderny, AstraZeneki or Johnson & Johnson, they may experience night sweats. It is about a situation where sweating is so great that it is necessary to change pajamas or even bed linen. The vaccinated person may not experience increased body temperature at all. Nocturnal offspring may also feel cold and shivering.

If you look at the list of possible adverse reactions to vaccination of each of the preparations used in Poland, we will discover that only the manufacturer of the AstraZeneki vaccine writes about excessive sweating. However, each leaflet contains information about a possible fever. And it is this elevated body temperature that is primarily responsible for the phenomenon of night sweats in vaccinated people.

Increased temperature and excessive sweating are signals that the vaccine is working. The fever causes the body to defend itself and therefore activates the immune system to fight the “enemy”. This is how antibodies are made. In turn, the night sweats themselves are a thermoregulatory mechanism.

Excessive sweating also occurs, among others during infection

The phenomenon of night sweats is by no means a symptom reserved only for people newly vaccinated against COVID-19. This symptom is also observed in the case of infections, such as influenza, but also HIV, tuberculosis and infectious mononucleosis.

Excessive sweating at night can also be caused by medications, including antidepressants, hormone-blocking pharmaceuticals (used, among others, in the treatment of breast cancer) or agents administered to people suffering from diabetes.

Patients with dysregulated hormonal balance as well as women undergoing menopause also experience night sweats.
