First of all, you should pay attention to the microclimate of the room and bedding.

Too warm blankets, synthetic clothes, fever in the bedroom will inevitably cause bouts of night sweats. If the above is excluded from the list of causes of increased sweating, then other possible factors should be considered.

Excessive sweating can occur as a result of infectious diseases when there are periods of increase and a sharp decrease in temperature. A sharp decrease in temperature during viral infections (influenza, acute respiratory viral infections, mononucleosis), bacterial diseases (pneumonia, tuberculosis, endocarditis, lung abscess), septic fever is always accompanied by excessive sweating. A number of tumors also give a symptom such as increased sweating. Pheochromocytoma (an adrenal tumor that secretes catecholamines – adrenaline and norepinephrine) causes sweat overproduction due to increased hormone production.

Night sweats can be excessive With lymphoma, along with general signs of intoxication. Excessive sweating accompanies some endocrine diseases.

In women, increased sweating, leading to hyperhidrosis, occurs during hormonal changes: during pregnancy and perimenopause. On the background of a decrease in estrogen levels and an increase in the content of follicle-stimulating hormone, a change in the distribution of blood in the skin vessels occurs. This explains the sudden redness of the skin and sweating during hot flashes. Men can also experience night sweats during andropause, an age-related decrease in the production of the sex hormone – testosterone.

This disease is characterized by increased metabolism and body temperature, which causes hyperproduction of sweat. The nervousness and psychological instability characteristic of patients with thyrotoxicosis also contribute to increased sweating.

Hypoglycemia in diabetes mellitus leads to night sweats.

Acromegaly, which increases the production of growth hormone, is almost always accompanied by excessive sweat in the evening and during the night.

Be sure to mention obesity, which also increases sweating. This process can be associated not only with the activity of the endocrine glands but also with the use of products that stimulate the work of sweat glands.

At night, sweat may appear when there is a sudden cessation of breathing – apnea. As a rule, in this case, sweat appears mainly on the face. Excessive sweating can be caused by episodes of transient disturbance of cerebral circulation, hypertensive crisis, encephalitis, volumetric brain tumors. All these diseases can be accompanied not only by increased sweating but also by other signs of autonomic dysfunction: chills, a sense of fear, irritability.

Sweat on the face often occurs in Parkinson’s disease. Among the neurological diseases that accompany excessive sweating at night include panic attacks.
