Do you sweat too much during the night? Discover the possible causes!

Today we will deal with a subject that is not very commented but not less important: causes of sweating during sleep or night sweats. Keep reading and find out why you sweat too much during the night!

Sweating is a physiological characteristic of the body necessary to normalize body temperature. However, excessive sweating during a night may indicate a particular health problem .

Causes of sweating during sleep or night sweats

  1. Infectious diseases: tuberculosis

One of the main causes of excessive sweating at night are respiratory diseases, in particular, tuberculosis. One possible cause of night sweats is the Mycobacterium tuberculosis disease (MBT). It sits on immune cells, macrophages, and suppresses their activity. In response, cytokines begin to occur in the body. Therefore, the thermoregulation center is activated, the body temperature increases to subfebrile values ​​and the person sweats.

To diagnose tuberculosis, an x-ray of the lungs must be taken. To date, the disease is treated successfully with appropriate antibacterial drugs. By the way, in addition to tuberculosis, heavy sweats at night can manifest AIDS (acquired immunodeficiency syndrome) as well as a disease such as brucellosis. According to official data, around half a million people contract this disease every year.

  1. Perspiration during sleep and menopause.

The increase in night sweats in women can be a sign of the onset of menopause. It is believed that menopause in women begins after the last ovum leaves the ovary. With the onset of menopause, the level of the main female sex hormones decreases sharply.

The strong fluctuations of estrogen lead to the fact that the hypothalamus, the main center of regulation (including the regulation of temperature), begins to react with increasing body temperature. As a result, so-called “hot flashes” appear. However, there is no real need to cool the body, since it is due to a natural process that affects every woman in her adulthood.

Now, if a woman’s nighttime sleep is accompanied by excessive sweating, she should consult her gynecologist. He may prescribe a hormone treatment . In this case, you can indicate the supply of drug drugs with female sex hormones in tablets or pills.

In addition, if there is menopause, it is desirable to avoid the factors that cause the strengthening of the sympathetic autonomic nervous system. It is recommended to stop drinking alcohol, exclude products with caffeine and spicy foods from the diet . At night, it is also not advisable to make intense physical efforts.

By the way, to make sleep more comfortable, during menopause, you can sleep on a special cooling pad made of special material. To cool the body during sleep, you can place the ventilator at an appropriate distance from your bed, at the minimum speed (and never in front, to avoid excessive cooling, flu or colds).

  1. Oncological diseases: lymphoma.

Complaints from patients of excessive sweating at night may be a sign of a malignant lesion of the lymphoid tissue: the so-called lymphoma. As you know, lymphocytes: white blood cells normally destroy all pathogens that enter the body. However, in some cases they can degenerate into malignant ones. Thus, the cells become non-functional and stop performing this task.

Meanwhile, they continue to secrete mediators that go to the thermoregulatory center, the hypothalamus, causing an increase in body temperature. The disease is characterized by an increase in lymph nodes, as well as constant increases in temperature. As a result sweating occurs.

Additional symptoms are generalized itching in the body and weight loss. This is a classic manifestation of this disease. For an accurate diagnosis, a blood test is required. To date, lymphogranulomatosis is effectively treated.

  1. Cardiac dysfunction: myocardial infarction

Sometimes, the appearance of cold sweat may indicate a myocardial infarction. When the blood vessels are blocked, the heart stops supplying blood and the person feels intense pain behind the sternum. The cardiac function is damaged and the sympathetic nervous system is excited, which leads to an increase in perspiration.

There is a definite correlation between the severity of heart attack symptoms and the degree of sweating. A person who has suffered extensive damage to the heart muscle, sweats much more. In certain rare cases, the opposite occurs, and the patient only feels weakness and sweating without heart pain. This can happen, for example, in patients with diabetes mellitus or medicated with analgesics.

It is possible to identify a heart attack by means of an electrocardiogram. By the way, endocarditis can also manifest later in the night: bacterial inflammation of the heart. The accompanying symptoms are pain between the shoulder blades, difficulty in breathing and disturbances of the heart rhythm.

  1. Thyroid problems: hyperthyroidism

Increased thyroid function: hyperthyroidism can also manifest by means of night sweating. Hyperthyroidism produces a lot of hormones that stimulate the production of energy. This energy, in turn, causes an increase in body temperature. So that the body does not overheat, sweating occurs. To diagnose the disease, you must pass a blood test to detect thyroid hormones.

Hyperthyroidism is treated with the use of antithyroid drugs that reduce the level of thyroid stimulating hormone (TSH). Thyroid function can also be suppressed with radioactive iodine. In some cases, it is necessary to resort to surgery.

  1. The action of certain medications

Sometimes, various medications can also cause sweating during sleep. Among them we can count some as: antidepressants, medicines for the treatment of high blood pressure, migraines and anticonvulsants.
