Why we perspire and how?
Human skin has two types of sweat glands, sweat glands are the most alfarash and apocrine glands. For the sweat glands alfarash tubular shape and spread throughout the body except for some parts and some 2-3 million. And in areas where the skin is thicker, and the palms, for example, with an estimated population of 3000 gland/inch.
Each gland secreting a spiral shape section is located directly below the DermIS (the layer of the skin) adipose tissue and other tubular shape sorter is the tissue in the direction of the surface. The adult produces approximately 100 ml/24 hours, in the absence of increased warmth or physical effort, otherwise the production may increase to 10 l/day. The average daily production of 500 ml/day.
Ethnic gland functions
The most important function of the sweat glands is alfarash organization and through the events of cooling perspiration through pores which means that body temperature is about 37.
Know the sweating that the process of producing liquid consists mainly of water.
In addition to special chlorine and sodium ions, potassium, calcium, and magnesium, as well as some small metal such as zinc, copper, iron, chromium and nickel and lead a race some aromatic substances and small amount of lactate acid soils and all of the toxins that your body gets rid of them through sweating.
Increased sweating, hyperthermia (controlled area in the brain called the hypothalamus) and it is the entire body. As Jan nausea and emotional and psychological tension-controlled part of the nervous system and the sympathetic system is called this is called the emotional sweating and sweating are usually the palms, soles, and sometimes front), reduces sweating in the cold weather.
Apocrine glands are present in certain areas (such as the armpit, around my nipple breast and groin region.) wettoda deeper than its predecessor and is larger and excreted from the blog in response to hormonal induction viscous liquid, odorless component of fat and proteins, when his touch each other with the bacteria on the surface of the skin in the presence of heat and humidity is the smell.
To be sure that human sweat is odorless unless she analyzed him bacteria found on the skin surface temperature and excess moisture in the armpit.
These glands are surrounded by a group of nerves that respond to stimuli either internal or external:
Messages from the brain to increase body temperature.
Hormones.
Feeling.
Physical effort.
Axillary hyperhidrosis have increased the effectiveness of the sweat glands alfarash, which estimated 00052-00005 gland, cause unknown reason and the common and life-threatening, and that may be troublesome when family 1-3% of people in the second and third decade of life around them, both in terms of scenery or odorless where holding area race allowing bacteria to produce odor and the situation is even worse. The proportion of this type of sweating 40-50% of the types of hyperhidrosis.
Diagnosis is a plus, sweating, Visual lasts at least 6 months and is characterized by the following:
Hit bilateral and symmetrical.
Disability events daily.
Age of initiation is less than 25 years.
Positive family history.
Stops sweating during sleep.
Factors influencing the effectiveness of gelatine and sweating:
This is the problem of social medical condition to hinder his Insomniac on all levels and requiring treatment, gelatine and sweating on the top of the pyramid of proposed solutions, and must take several things into consideration when discussing the effectiveness of these products:
The type and size of molecules active substances.
Be pH and alkaline product commensurate with those on the surface of the skin.
You must be specific tests of the food and Drug Administration on the final version of the check their effectiveness and safety.
Gender tests of physiological differences among them.
Make sure the content of the information on your product.
It is important to know that by reducing sweating effect regular removers do not exceed 20%, while up to 30% of species to reduce sweating by doubling or maximum rate. This is important for consumer education about the degree of expected effectiveness.
No standard practical and clear about the proper dosage for application of power spray or distance or angle optimization and unsprayed or even a sprinkler, or total area and area.
There are always personal differences between people in terms of the individual’s response to any product.
Odor removers
Are applicable to any area of the body to reduce the smell of decomposition of sweat by bacteria. And are dependent on alcohol to get the effect of coolant when it evaporates, while the latter promotes sweating, but it kills the bacteria. Add some gelatine bacterial antagonists is more effective, such as triklosan, or slow the growth of bacteria. It also includes natural essential oils or fresheners to mask the smell of sweat.
Abrasives sweating
Gelatine under a group called removers sweating, perspiration odor prevention to reduce or minimize sweat production in certain areas of the body such as the armpit, and this reduces the humidity of the area and prevents the growth of bacteria.
Gelatine is classified as cosmetics and medicines by sweating removers food and drug administration. The aluminum salts in their various forms the main component of these lotions particularly aluminium chloride, aluminium hidroklor.
Aluminium based vehicles interact with ions of sweat to form a gelatinous plugs in sweat gland secretion prevents the nozzles, removed the plugs with the time by epidermal regeneration. Mineral salts also works the other way, interacts with leyevat keratin in glands and channels constitute physical seals prevents sweat from reaching the surface of the skin. Add to the above the aluminum salts impact handle simple pores causing contraction is added as an aid in preventing sweat from reaching the surface.
The large number of sweat glands alfarash of action reduces the amount of sweat in the armpit, but this varies from person to person.
Start of production of these products in the late 19th century (1888), and demand increased after World War II when the increased managerial, showing the importance of the external appearance of the employee and an important part of the job qualifications. The industry subsequently evolved in terms of pharmaceutical formulation and outer shape and use, and the options are innumerable and are steadily increasing.
There have been problems at the end of the 1970s the popularity of these products have changed, first pull the material aluminium-zirconium in 1977 for lack of integrity if inhaled long-lasting, the second reduction of use of chlorofluorocarbons in the forms of the sprayer by EPA in alarzazat of the negative impact on the ozone layer.
Natural sweating removers:
Also known as “gelatine natural Crystal”, consisting of potassium alum. It has gained high popularity in recent alum alamoniomi (a common type of alum Crystal) as an alternative to commercial products, and has been used in Thailand, and the far East, and Mexico.
Side effects of deodorants
A small percentage of people sensitive to aluminium, and may cause dermatitis in contact. Either Abrasives sweating containing industrial potash alum can sometimes by scratching.
Neurotoxicity of aluminum in deodorant
Aluminum is toxic in large doses, nervous and studies show that high doses of aluminum hurt many objects but as amphibians, mice, and dogs where up in the urine, blood, and brain. FDA confirms the possibility of absorption of aluminum through the gastrointestinal tract and through the skin.
High back aluminum encephalopathy in patients with Alzheimer’s disease in many studies and tied together with long-term use of abrasives of sweating. And Alzheimer Society has stated: the existence of many environmental factors associated with the disease, including aluminum, but revealed no causal link between the abrasives sweating and disease. In addition to the above and because of the prevalence of this metal in nature and the different products it has been shown that the human Gets the metal through the air, water, food and daily care products, aluminum salts are absorbed by applying Abrasives sweating only 2.5% of the total.
Deodorants and breast cancer
Rumors of anonymous since the 1990s online about the relationship of the abrasives sweating with breast cancer, and epidemiological studies of isolated non-different from the most common, which led to the American Society of Oncology and the National Institute of Oncology of scrutiny through intensive studies found no clear relationship between the abrasives and breast cancer.
Deodorant and patients with renal failure
Food and Drug Administration advises that renal failure patients to consult their doctors before using Abrasives sweating containing aluminium salts of this element accumulation in the body.
Deodorant effect on clothing
Some removers sweating containing zirconium causing discoloration of the armpit and clothes because of their interaction with race leading to a yellow pigmentation.
