What are the symptoms of excessive night sweats?

It has happened to all of us that we wake up in the middle of the night feeling hot and maybe a little sweaty. But the heat of summer and turning off the air conditioning overnight can not be a convincing reason to wake up in sweaty clothes and bedding. This phenomenon, which is associated with nocturnal sweating in medicine, has nothing to do with the heat and condition of your bedroom, and usually has other causes. Menopause or premenopause is the first possible cause of night sweats due to hormonal disorders in the body.

But this is not the only cause of night sweats, and many people have not yet reached menopause, and some men have the problem. In the following, we want to acquaint you with the most important possible causes of this unpleasant anomaly. Be with Dr. Salam.

All of these are directly related to cardiovascular disease, and this is the link between night sweats and an increased risk of cardiovascular disease.

Your body may be fighting an internal infection

When our immune system is fighting a disease or infection, the body temperature rises and this can lead to night sweats.

In this case, you can change the type of painkiller you use in consultation with your doctor. Also keep in mind that if you always need medication for headaches and fever, you probably have a more serious problem that you should definitely talk to your doctor about.

Your body’s defense system may be at fault
