Increased sweating is technically known as hyperhidrosis. Night sweats are called nocturnal hyperhidrosis. Some people regularly sweat profusely at night. This can have different causes. An important criterion for assessing night sweats, which is often asked by the doctor, is whether the night sweats were so severe that the pajamas had to be changed or the sheets were soaked.
In principle, sweating is something natural and is used by the body to release excess heat from the inside to the outside. This occurs especially when the outside temperature is warm, during physical activity or when there is a fever as part of an infection. A sweat release of up to 500 mL at night is considered normal. At night, especially in the first half of the night, the average body temperature drops by 1.5 ° C. The body releases this heat to the outside. To do this, however, the environment must also be able to absorb the heat. For example, if you lie under a thick blanket, it is more difficult to give off heat. The heat is then given off through increased sweating. Night sweats are usually a harmless cause that can be easily remedied. However, if night sweats persist for three to four weeks, a doctor should be consulted for clarification. Especially if there is also a fever, unwanted weight loss, fatigue or unspecific pain.

Night sweats are a symptom that may initially have many different causes. The definition of night sweats is also not uniform, which is why there is often confusion about what can be called night sweats. Doctors initially mean by night sweats in the narrower sense a very strong night sweating, which prompts you to change your nightgown or even the bed linen. Sometimes the sweat is so pronounced that the laundry is even changed several times at night.
Behind such night sweats there is a disease, for example from the rheumatic type or a cancer disease that must be treated by a doctor. Infections can also cause night sweats. Unfortunately, there is nothing you can do about this type of night sweat yourself.
Many people perceive night sweats to be less intense night sweats. This type of "night sweat" is usually not caused by the disease, so you can do a lot yourself.

Furthermore, you should choose breathable, lightweight materials for bed linen and nightgowns. Cotton is very suitable in this case, whereas polyester or satin should be avoided.
Before going to bed you should avoid spicy food, caffeinated drinks or alcohol, as these increase sweating.
Sage or chamomile tea is recommended in the evening. In addition, cool compresses on the wrists can help cool down a bit and sweat less.
A simple and also the most common explanation for night sweats are hot summer nights, bedding that is too warm or an outside temperature that is too high, for example because the heating is set too high. But rooms that are too cold also lead to excessive sweat production. Heavy alcohol consumption and spicy food can also lead to sweating at night. Alcohol leads to the fact that sweat production leads to an increased excretion of fluids, whereby not only water but also minerals are removed from the body. Especially at night, alcohol stimulates the metabolism, which leads to the production of heat. Sweating occurs as a symptom, especially with alcohol withdrawal. Also increased psychological stress or nightmares, as well as nocturnal breathing pauses (Sleep apnea syndrome) can lead to sweating at night.Because if the inner restlessness does not stop at night, the body is constantly under tension, which leads to an increased release of the stress hormones adrenaline and noradrenaline, which then leads to increased sweat production. At night, your own worries usually come to the fore as the distractions that exist during the day are no longer there. If night sweats still occur after these causes have been resolved, you should consult a doctor, because night sweats are not always caused by such harmless triggers.

Before the onset of menopause, female production increases Sex hormones (Progesterone and estrogen) for a short time. If the menopause then occurs, the estrogen level suddenly drops again. This reactively increases the production of stress hormones adrenaline and Norepinephrine on. These two hormones can then lead to increased sweat production and the hot flashes generally associated with menopause. Sometimes this night sweat can be very massive, so that the laundry is sweated through several times a night. However, these typical symptoms do not occur in every woman going through menopause. Some are also not affected at all. Hormone fluctuations do not only occur in women over the years; testosterone levels also drop in men according to their age, which can also lead to night sweats in men. However, this is much less the case with men than with women.
$config[ads_text1] not foundSome medications can trigger night sweats. These include drugs that affect the autonomic nervous system, ie Sympathetic and Parasympathetic nervous system, because sweat production is mediated via the sympathetic and rather inhibited via the parasympathetic. Sometimes night sweats only occur in the initial phase of taking, in other cases it occurs when the medication is used for too long or in a too high dosage be taken. If night sweats are felt to be stressful, the medication should not simply be discontinued, but a consultation with the attending physician should be made.

The first night sweats often occur in this phase, which is accompanied by fever, fatigue and swollen lymph nodes. Then one follows asymptomatic phase.
If the thyroid is responsible for night sweats, it is usually an overactive thyroid (hyperthyroidism). The increased sweat production occurs during the day as well as at night. Often lead Autoimmune diseases, such as Graves disease, to an overactive thyroid, which leads to an increased production of thyroid hormones. The hormones make the metabolism more stimulated. In addition to night sweats, there is also increased internal restlessness, Mood swings, Weight loss, one increased heart rate, as well as the mentioned night sweats.

Even with one chronic lymphocytic leukemia, a blood cancer originating from the lymphatic system, night sweats can occur as part of the B symptoms. Incidentally, the complete triad of the B symptoms does not always have to be present. In addition to lymphomas and leukemia, it also occurs with the Myelofibrosis often to night sweats.

Night sweats can occur during pregnancy due to hormonal fluctuations.
Sweats during the day or hot flashes can also be present during pregnancy. Only in very few cases is a serious illness hidden behind night sweats during pregnancy. As a rule, the increased sweating is due to the hormonally very special situation of pregnancy.

Sweating on the head is described by those affected as very uncomfortable and sleep-consuming. It often happens because of this sweaty hair, as well as an itchy scalp. Sweating on the head is promoted by various factors. Mainly by consuming spicy and fatty foods just before going to sleep, as well as a strong one Alcohol consumption. Also overweight persons often sweat profusely on the head.
In addition to the manifestation of sweat on the head, the head is also a cause of increased night sweat production. If you worry too much or you can't switch off and are exposed to higher internal tension, the body is more active at night and stress hormones are released, which stimulates sweat production.
There are many sweat glands on the upper body, which is why sweat can literally drip off the body. This is the case when there are real sweats or night sweats. The latter can occur due to a wide variety of causes and usually affects more than just one region of the body. Typically, the upper body is almost always affected by night sweats. Especially the V-shaped area of the chest and shoulders sweat particularly heavily, so that there are typical sweat stains on the nightgown.
Hot flashes and sweats are usually more pronounced on the trunk of the body, i.e. on the back and chest, than on the extremities (arms and legs). The cause can be various things, such as infections, autoimmune diseases or even cancer.
However, you should note that night sweats on the upper body in the true sense of the word mean that you have to change your nightgown more than once at night because of the sheer sweat.
Especially when the outside temperature is warm, it is quite normal for you to sweat more on your chest at night. But this is not yet called night sweats.
The chest and neck are very heat-sensitive areas of the body. With high outside temperatures, nervousness or fever, you sweat a lot here. Sweat stains and a dripping neck can be the result.
Night sweats can also show up in these parts of the body. Especially with the flu or another febrile infection, increased night sweating of the chest and neck is very common.
Even being very overweight can lead to increased sweating of the chest and neck, which is often very uncomfortable for those affected. In the case of very heavy night sweats and accompanying symptoms such as fever, weight loss and malaise, causes such as cancer or autoimmune diseases must also be considered.
Only the legs are rarely affected by night sweats. Night sweats in the narrower sense affect several parts of the body and are basically never found in isolation on the legs.
A simple cause of increased leg sweating at night is too high a temperature in the bedroom.
Anyone who heats too much or sleeps under too thick blankets sweats very quickly at night. This can only affect the legs, as these are usually covered.
Restless legs syndrome is a less common reason for night sweats. It is a common neurological disorder, but not always associated with night sweats. Typical is an increased urge to move the legs, which increases especially at night and in the evening. Sleep disorders are often associated with restless legs syndrome.
In children, it usually comes through, similar to adults Infections to a night sweat. Since the immune system in children is not as well developed as in adults, febrile infections are more common in children than in adults Night sweats can go along. In an emergency, such an infection is a real flu, the influenza. Fortunately, mental problems / worries are relatively rarely the trigger for night sweats in children. One should also look for the cause of night sweats in children Sleeping conditions check whether the child is not wrapped up too warmly or the heating has been set too high. This is the most common reason for night sweats in both children and adults, as children are usually even more caring and want to protect them from freezing, which is sometimes a bit too much. But serious causes can also be responsible for night sweats in children. For example acute lymphoblastic leukemia, which occurs most frequently in childhood. In the beginning it often manifests itself in addition to night sweats fatigue, Exhaustion, Headache and body aches, flu-like symptoms. Otherwise, with a few exceptions (e.g. menopause), the same causes for night sweats as in adults are possible in principle.
In order to determine the cause of the increased night sweats, the attending physician must carry out various examinations and a detailed doctor-patient discussion. If night sweats are the only symptom, a diagnosis is particularly difficult. The family doctor often consults various specialists, such as an internist, neurologist, or oncologist Endocrinologist. During the physical exam, it is important to have blood pressure as well as that Body temperature to eat. It is also important to scan all lymph nodes. Swollen lymph nodes in combination with night sweats indicate an infection in most cases, but can also indicate a malignant disease. A laboratory test is also carried out. For this purpose, inflammation parameters, the blood count, liver and kidney values, the sex and thyroid hormones, as well as the stress hormones adrenaline and noradrenaline are determined. Also one HIV serology can be done from the blood test. Sometimes this is followed by an X-ray examination, through which, for example, the suspected diagnosis of a tuberculosis can be hardened. An ultrasound diagnosis is often part of the clarification.
The therapy always corresponds to the underlying cause and therefore, unfortunately, can usually not be described in general terms. Often the night sweats subside after an infection has been overcome. But it also happens that the doctor cannot find a cause for the night sweating, in this case the doctor speaks of a so-called idiopathic night sweats. In these patients, the sweat glands are unknown to be overactive. In these cases, however, patients also sweat more during the day. These patients are usually advised to change their living and sleeping habits. These measures include doing little or nothing in the evening alcohol should drink. Besides alcohol should also caffeinated drinks be avoided. Furthermore, no greasy and spicy foods to be consumed more. The evening meal should ideally take place two to three hours before going to bed. On Smoke should also be omitted. Since night sweats are often provoked by warm outside temperatures or by too warm pajamas or duvets, it is helpful not to wear tight-fitting pajamas, but rather light pajamas. Also the Room temperature should be adjusted in the bedroom. The ideal sleeping temperature is around 18 ° C. If the problem lies in switching off in the evening and going to bed stressful, help before going to bed Relaxation exercises, read or quiet music.
Night sweats are a symptom that can be traced back to many possible causes. It is therefore important to clarify the cause of night sweats before attempting to treat it.
There is no treatment for night sweats as such, as it is always an expression of an underlying disease.
Homeopathic remedies cannot be recommended for night sweats as they neither differentiate according to cause nor are they effective. There are also no standardized recommendations from homeopathy, so that we strongly advise against them.
Some of the possible causes of night sweats require acute treatment, such as cancer. In such cases, the use of homeopathic remedies would be grossly negligent.
