I sweat at night: what does it hide?
As a normal and essential phenomenon, perspiration allows the body to regulate its internal temperature, but when it is necessary at night for no apparent reason, it can testify to a pathology that is smoldering. Not necessarily worrying, but to take into account. Small inventory decrypted by our specialists.
Night sweating: what if it was sleep apnea?
This syndrome, characterized by recurrent respiratory arrest of 10 to 30 seconds, or even a minute, causes a decrease in blood oxygenation during sleep. The consequence? The rate of blood carbon dioxide is rising, and that is what makes copiously sweat. " Women are often told that they have hot flushes at night, when in fact they make sleep apnea ", warns Dr. Patrick Lemoine, sleep specialist and co-author of Sleep! (Hachette ed.)
The right attitude: Lighten up a few pounds if you are overweight, because the fat is also installed in the throat and in the tongue, promoting the obstruction of the airways. For moderate to severe apneas, the reference treatment is Continuous Positive Pressure (CPP). This involves blowing air at a certain pressure in the airways, via a mask positioned on the nose, to prevent their closure and preserve oxygenation. For the future, a small implantable box in the back of the throat, like a pacemaker, is being evaluated. It works by delivering a pulse that keeps the airways clear.
Night sweats: and if it was due to a hormonal imbalance?
" Women do not always pay attention to these night sweats, because they only have moist skin or they think they are too covered, while that may indicate that they are gently entering premenopausal unknowingly, sometimes as young as 35, and therefore their fertility drops. This is a warning sign for those who have not yet had a child ", warns gynecologist Christian Jamin.A clarification: Under pill, where the cycle is artificially regulated, nocturnal sweating occurs during the week of stop Another concomitant indicator: the cycles shorten, sometimes minimally, from 28 to 26 days .
The right attitude: Perform a blood test with a dosage of the hormone AMH, to assess the stock of oocytes in the ovaries. " This is all the more crucial since the Bioethics Law now authorizes the self-preservation of oocytes, called follicular cryopreservation, in early menopause. This saves her fertility and can be pregnant afterwards ", insists Dr. Jamin.
Night sweating: it may be caused by hyperthyroidism
The thyroid gland is racing and overwhelmingly floods the body with hormones. Result: the latter goes into over-regime and body temperature climbs seriously, with a night bonus. " 44% of people sweat profusely even at cool ", reports Dr. Pierre Nys, endocrinologist-nutritionist.
The right attitude: Determine the hormone TSH. Secreted by the pituitary, it orchestrates the functioning of the thyroid. Its normal rate is between 0.27 and 4.20 mIU / L (depending on the laboratory, the range may vary). Low TSH levels lead to hyperthyroidism because the pituitary gland reduces the secretion of TSH to slow down the thyroid gland. Sweating is often accompanied by rapid transit, a racing heart, weight loss despite a strong appetite. " On a day-to-day basis, be sure to limit the stress, possibly involved, as well as endocrine disruptors and other pollutants that thwart the thyroid ", advises the endocrinologist.
I sweat a lot at night: what if it was due to an infectious disease?
Tuberculosis in particular, transmitted by the bacillus of Koch, expresses itself by specific sweats in the evening or at night. " There is no chills, fever, or minimal (between 37 ° C and 38.2 ° C). These are cold sweats, medically named nightly sweats, but we do not know why they occur in the evening ", says Professor Olivier Bouchaud, head of the infectious and tropical diseases department at the Avicenne hospital in Bobigny.
The right attitude: Consult, especially if sweating occurs after returning from vacation in endemic areas of malaria, dengue, chikungunya. An antibiotherapy tablet for six months effectively treats tuberculosis. Other anti-infective and anti-parasitic treatments are adapted on a case by case basis.
Night sweating: it can be due to too rich a diet
You will no longer see ice cream cones and other churros of the same eye. Because it is in the proper sense that sweets sweat. In cause, over-production of insulin to regulate blood sugar, blood sugar levels. But the hearty dinners, alcohol and spicy foods do not do better: they trigger the alarm of the cerebral thermostat, raising the internal temperature, and therefore that of blood. Because any increase in the latter is synonymous with potential danger. Sweating is then immediate to maintain body and blood at 37 ° C.
The right attitude: Do not calm the fire effect by drinking ice, because the body will start by heating the liquid to assimilate it, raising a little more the temperature. Knowing that, as a bonus, digestion increases it immediately. " Occasionally, you can go to bed taking paracetamol, says Dr. Lemoine, to lower the core temperature and reduce inflammation ".
Night sweating: when should you worry?
If we start to sweat at night, we do not panic. This occurs at certain periods of life, when one is more tired or stressed, without this being a sign of a progressive or serious disease. It's just a mode of body response to a particular difficulty. If it lasts less than 15 days and disappears without further signs, there is no need to worry. If this persists for more than 15 days or if sweats come back regularly, combined with fatigue, pain or weight loss, consult.

Bring to a boil 1 tbsp. coffee sage leaves for a cup of cold water and let infuse 10 minutes. " In a course of 10 to 20 days, up to 2 to 3 cups a day, except in case of hypertension and disease or hormone-dependent cancer ", advises Dr. Franck Gigon, Phytotherapist, author of The best plants that look after (Leduc ed.)
