During the day, most people lose about 800-1000 ml of liquid afterwards. Sometimes this amount increases to 3 liters, and in extreme conditions the human body can produce about 10 liters. sweat. Sweating is a natural process by which thermoregulation occurs. By the way, male organisms are characterized by a lower thermal threshold, therefore, compared with women, the stronger sex sweats more strongly.
If your hands become wet in hot weather or under stress, this is the norm. However, if palms sweat frequently and intensively, or remain constantly wet, this at least causes discomfort, and sometimes indicates serious health problems.
Causes of excessive sweating
Sweat in the human body plays the role of the thermostat. Therefore, sweat secretion is activated when the body temperature rises above normal. This can happen in hot weather or with viral, infectious or inflammatory diseases. However, sometimes the sweat glands produce an excessive amount of fluid without seemingly obvious reasons.
Increased sweating can markedly worsen the quality of life. Wet hands make it inconvenient to use the phone or work at the computer, drive a car, or even open the door. From wet hands, items easily slip out, wet fingers leave marks on documents, and sweaty palms can be disgusting when shaking hands.
Causes of excessive sweating may be different. For some, this happens in moments of fear, for others due to genetic factors. If the increased sweating of hands is congenital, then, as a rule, it manifests itself even in childhood, and increases during puberty. Sometimes the sweat glands become too active as a result of injury. In addition, sweating of hands can be an indirect sign of various disorders in the body. For example, palms can sweat a lot when:
- sugar / diabetes mellitus;
- infectious diseases;
- hormonal disorders;
- neoplastic diseases;
- ailments of the central nervous system;
- vascular dystonia.
Experts distinguish 4 types of excessive sweating on the hands. The first group includes people with not very strong sweating of the palms, while the fourth group includes people whose hands sweat so much that moisture literally drips from the skin.
Hyperhidrosis of the palms
The most common cause of increased sweating of the palms is hyperhidrosis. This violation occurs due to malfunctions in the functioning of the sweat glands. Hyperhidrosis can be total, that is, spread to the whole body, or touch only certain areas, for example, palms.
Experts do not know the exact cause of hyperhidrosis, but most assume that it is all about the hyperactivity of the sympathetic nervous system. The sympathetic nervous system controls those reactions that release adrenaline, accelerate heart rate, constrict blood vessels and regulate sweating. Depending on the causes of excessive sweating, the hyperactivity of the sweat glands can be symptomatic or idiopathic. In the first case, excessive sweating of the body, including the palms, is a "side effect" of the disease or overheating of the body in hot weather. Idiopathic hyperhidrosis (or primary) appears regardless of weather conditions or diseases.
Diet and medication
Excessive sweating of the hands can also occur on the background of a specific diet. For example, wet palms are often among people who are too keen on spicy spices, hot peppers or caffeine. These products are activated in the body by the neurotransmitter acetylcholine, which in turn enhances the work of the sweat glands. In addition, acetylcholine can provoke the release of stress hormones, which further aggravates the problem of excessive sweating of hands. The cause of wet palms can also be taking certain medications or stimulants.
Sweating hands during stress, for example, during a job interview or public speaking, is a fairly common symptom that should not cause concern. But only if, in addition to sweaty palms, there are no other alarming symptoms.
Wet hands are a normal response of the body to feelings, anxiety and stress.
This is due to the release of stress hormones - cortisol and adrenaline. Studies have shown that these hormones not only help to cope with stressful situations, but also cause an increase in body temperature, as a result of which the sweat glands are activated. If a person is in a state of chronic stress, it is not surprising that his hands are also always wet.
If during public projections or conversations with other people, in addition to sweating hands, dry mouth, trembling, redness of the skin, heartbeat accelerates and frequent urination, an individual can be suspected anxiety disorder (a form of social phobia). If the disorder is ignored, it can lead a person to complete social isolation. People with this type of disorder also often suffer from depression, dependence on alcohol, sedatives or psychoactive substances. By the way, among people with anxiety personality disorder there is a rather high percentage of suicides.
In addition, sweaty palms are one of the hallmarks of a panic attack. With this symptom usually appear shortness of breath, nausea, dizziness, rapid heartbeat.
Sweaty palms can also indicate the presence of toxic substances in the body. In any form of poisoning the body tries to get rid of harmful substances along with sweat, therefore, in the presence of toxins, the sweat glands work is activated.
The presence of excess weight is another possible reason for the increased activity of the sweat glands, including on the hands. Excess weight is an additional load on all organs and systems of the body. In the enhanced mode, the sweat glands of obese people also work.
Any fluctuations in total hormonal levels affect the work of most systems of the human body.
Hormonal spikes can disrupt the natural functionality of the sweat glands. In 2010, the American Journal of Dermatologists, the Journal of Dermatology, published the results of a study that scientifically confirms the connection between the increased activity of the sweat glands and the thyroid gland. In particular, excessive sweating of hands may indicate the presence of hyperthyroidism - an increased thyroid hormone activity.
In women, sweating flashes are most common during menopause. This is due to fluctuations in the levels of sex hormones estrogen and progesterone. In addition, possible changes in the activity of sweat glands during the menstrual period and during pregnancy, which is also associated with fluctuations in hormonal levels.
Low blood sugar
To maintain performance, the human body is constantly in need of carbohydrates. If the body does not receive them, the blood sugar level decreases. In order to somehow survive this critical period, adrenaline is released in the body, which stimulates the release of sugars from the reserves. This process is a kind of stress for the body, so during such a shake up sweating and palms become wet.
If a person eats regularly and more or less in a balanced way, and during the day such “bouts” of sweating still occur, this can be a signal of the development of diabetes mellitus.
It is scientifically proven that a glass of good wine has various advantages for the human body. But if a person is prone to excessive sweating, then even one serving of alcohol can aggravate the problem. Alcohol causes dilation of blood vessels, which in turn has an additional thermal effect on the skin. Further, the parasympathetic nervous system is activated in the process, which activates the sweat glands to reduce body temperature. For this reason, people who abuse alcohol regularly suffer from chronic sweating of the palms.
If a person constantly sweats hands, the cause can be searched in genetics. Interestingly, the tendency to excessive sweating can be transmitted through several generations, for example, from grandmothers, grandfathers or more distant relatives.
According to research in approximately two thirds of cases, excessive sweating of the palms is hereditary.
In 2002, scientists at the University of California discovered the "bad" genes that are responsible for the increased sweating in the palm area. This discovery confirmed the theory that increased hand sweating is not always the result of stress or emotional disturbances.
As evidenced by sweaty palms
Those who are faced with the problem of excessive sweating on the hands, agree that there is little pleasant in such features of the body. Nevertheless, few people know that by the intensity, consistency and temperature of that very sweat one can learn a lot about the state of health.
If the sweat on the hands is cold, it can be a sign:
- weight deficit;
- lack of vitamins and minerals (especially magnesium and iron);
- circulatory disorders (including due to a sedentary lifestyle and lack of fresh air).
Cold sweat on the palms can often be seen in smokers and alcohol abusers. In addition, wet and cold hands can be one of the symptoms of diabetes, thyroid disease or nervous system, osteochondrosis, vascular dystonia, Raynaud's syndrome.
No less alarming is sticky sweat. It can appear in case of diabetes, pancreatitis, serious heart disease, or severe intoxication caused, for example, by large amounts of low-quality alcohol. If sticky sweat appears at night, is accompanied by general weakness and low-grade fever, this may be one of the signs of tuberculosis. Sticky sweat on the body, including the hands, in combination with an increase in the lymph nodes of the neck and pale skin sometimes indicates the growth of a malignant tumor.
Separately, it should be said about the sweating of hands in children. If the child's palms are often wet, this is a reason to show the baby to the doctor. Sometimes this happens with a deficiency of vitamin D, heart failure, excessive activity of the thyroid gland, or against the use of antipyretics or painkillers.
How to deal with sweating hands
Diet. The fight against excessive sweating should always begin with a correction diet. In particular, it is important to eliminate all hot spices from the menu, as well as to limit the consumption of caffeine. In addition, it is important to adhere to a balanced diet, eat foods rich in vitamins and healthy microelements. By the way, the wrong diet leads to an imbalance in the body - at the physiological and mental level.
Any imbalance, in turn, leads to chronic diseases, weight gain, anxiety increase. As a result, the wrong diet can be an indirect cause of sweating.
Another tip that may seem strange to some: drink plenty of water. Yes, in order to reduce sweating, you must give the body the necessary fluid for it. Drinking helps cool the body and thereby reduce perspiration.
Specialized cosmetics. To relieve sweating of hands at home will help antiperspirant gels, which include substances that suppress the secretion of sweat. In addition, such agents usually have a bactericidal effect and are well refreshed. Wet wipes, talc or ordinary corn starch will not help to cope with the problem forever, but with their help the palms can remain dry for some time.
Folk methods and pharmaceuticals. To reduce the activity of the sweat glands will help bath of decoctions of sage, rosemary, oak bark, a solution of sea salt, soda or apple cider vinegar. They are convenient to use at home. A similar effect is given by products containing tea tree oil, essential oils of lemon, lavender, fir, boric acid, aluminum chloride, zinc. One of the most affordable and popular anti-sweating remedies is Teymurov ointment, which is applied to the skin for 15-20 minutes, and then washed off. In the pharmacological treatment of excessive sweating caused by stress or nervous breakdowns, use drugs that include belladonna, phenobarbital or hydroxyzine.
Botulinum toxin injections. In case of hyperhidrosis, botulinum toxin injections can also be helpful. The drug is administered in a highly sweating area. The principle of action lies in the fact that this substance blocks the work of nerve cells responsible for the secretion of sweat glands, while not damaging the glands themselves. The effect of the procedure is maintained for about six months, and then gradually the work of the nerve cells is restored.
Sympathectomy. If invasive and traditional methods of treating excessive sweating of the hands do not help, resort to an operative method - sympathectomy. The essence of the procedure is to block the nerve impulse coming from the sympathetic nervous system to the sweat glands. In simple words, during the operation, the nerves are squeezed or the sweat receptors are completely destroyed, that is, the nervous system ceases to give an attitude to the development of sweat in the palms. After surgery, the hands stop sweating forever.
Iontophoresis. Another treatment for excessive sweating of the palms can be offered in beauty salons. The procedure of iontophoresis is completely painless. It is carried out using a low-intensity electric current. The current passes through the upper layer of soft tissues, where the sweat glands are concentrated, limiting their secretory activity. During the procedure, the ion channels are damaged, but the sweat glands themselves are not destroyed. The iontophoresis procedure lasts about 30 minutes. The patient puts his hands in a vessel with water, through which light discharges of electricity pass. Iontophoresis does not cause painful sensations - only a slight pricking in the palms. The procedure is repeated every 2 days to achieve the desired effect. The disadvantage of this method: the result is short-lived, after some time (approximately 6-8 months), the course will have to be repeated.
Only people who are personally confronted with this problem fully understand how much sweaty palms make life difficult. However, we must not forget that nothing in the human body does not arise just like that. If palms sweat more than most other people, then there is a reason to look for the cause of this condition. It is possible that sweaty palms are a sign of a serious illness.
