An antiperspirant is a sweat-inhibiting substance in deodorants. Antiperspirants temporarily constrict the openings of sweat glands and thereby inhibit sweat formation. This is important for the functionality of an antiperspirant because the bacteria in sweat causes unpleasant body odour. Aluminium chlorhydrate is often used in antiperspirants because it is highly effective.
Apocrine sweat glands do not regulate the body temperature like eccrine sweat glands. Their purpose is to release scents, which act as sexual attractants, to find milk-supplying nipples, or to mark territorial boundaries as in the case of animals.
This dysfunction usually affects the apocrine gland, which produces the scent in sweat. The consequence is a poignant smell of perspiration. This dysfunction often occurs in puberty when the sweat glands shift to producing sexual scents. Different forms of therapy are available to sufferers.
Cold sweat can have many causes, often due to illnesses or cardiovascular/circulation problems that do not relate to regulating body temperature. The reason why the sweat seems cold in such critical situations is that the blood is kept deep within the body and the skin then cools down. The sweat feels colder because the skin is colder under this condition.
Eccrine sweat glands regulate body temperature instead of producing scent like the aprocrin sweat glands. Approximately 2 to 4 million sweat glands moisten the skin by releasing fluid, which has a cooling effect when it evaporates. Eccrine sweat glands can take over rudimentary detoxification tasks if kidneys have functional disturbances.
This widespread dysfunction refers to the bodys deficiency in regulating its temperature, which can cause strong perspiration when the body is exposed to hot outdoor temperatures or exertion. Although a normal body reaction, patients suffering from hyperhidrosis excessively produce perspiration, which appears in armpits, hands and feet and does not help to regulate the body temperature. However, there are various therapeutic remedies to help sufferers reduce excessive sweating.
Loss of electrolytes
This problem should not be neglected with heavy and long periods of sweating. When the body lacks electrolytes, the supply of important nutrients in the body is impaired. Cramps, nausea, and circulation problems can result. Therefore, one should be careful to refill electrolytes after heavy sweating. In severe cases, special beverages or compounds can be used. Usually, it is sufficient to eat some fruit and drink enough mineral water to compensate for the loss of electrolytes.
Women in menopause often have a problem with hot flashes and perspiring due to fluctuations in hormone levels. When estrogen levels decline, the temperature centre is stimulated which falsely diagnoses overheating and reacts with adrenalin boosts and sweat outbursts.
Contrary to popular belief, fresh perspiration is odourless since it contains 99% water. Body odour only occurs when it remains on the skin for a longer period of time and is decomposed by bacteria. Every person has their own scent, which was an important function in earlier times when humans communicated less with language than with scent.
Today, this function is annoying. Deodorants counteract this. It is important to know that deodorant should be applied to freshly cleaned skin to better inhibit the formation of perspiration.
It is interesting that armpits contain only 1% of all sweat glands. That means that more sweat is not produced here than in other areas of the body. The reason why an unpleasant odour can result quicker here is the restricted opportunity for sweat to evaporate in the armpits. Bacterial decomposition is fostered and odour formation accelerated. That is what makes armpits problem zones.
The choice of wardrobe plays a decisive role in the formation of perspiration. In general, clothing should fit loosely in order to avoid heat accumulation. Synthetic fibres should be avoided as much as possible because they do not breathe. Cotton textiles (as well as leather shoes) should be preferred in order to regulate sweat formation.
Three types of perspiration
The most important function is thermal perspiration because the skin and body cool down high body temperatures caused by exercise or hot outdoor temperatures with perspiration.
Emotional perspiration occurs during mental strain, such as stress or fear, and had a signal effect in prehistoric times, similar to animals today.
Gustatory sweating develops from the taste of food or beverages, but is often a disturbance of the perspiration function.
