What Are Common Causes of Fatigue and Sweating?

Sweat (sweat) is a fluid secreted by sweat glands. Sweating caused by thermal stimuli caused by an increase in outside air temperature or an increase in heat production in the body is called perceptual sweating, and the sweat itself is odorless. At this time, the sweating area is widely distributed, and the skin of all parts of the body, especially the forehead, neck, front and back of the trunk, waist, back of hands and forearms, is the most; second is the neck, the side of the trunk and most of the limbs; again the medial side of the thigh and the underarms ; At least palms and feet. Strains also cause sweating. Sweating centers are distributed in various parts of the central nervous system. Normal people unknowingly evaporate about 600 to 700 milliliters of water within 24 hours.

Sweating is a common physiological phenomenon. Sweating occurs when the weather is sweltering, and sweating when the mood is tense. It can be seen that sweating is a function of regulating body temperature, evaporation and heat dissipation, and it is also a kind of emotional response. Sweat is excreted from the sweat glands. Sweat glands are distributed in the dermis of the skin throughout the body, with large and small sweat glands. The large sweat glands are mainly in the armpits, nipples, and perineum, and the small sweat glands are distributed throughout. The sweat glands are one of the most developed organs in humans. The total number of sweat glands in the human body is between 2 million and 5 million. The amount of sweat secreted and the speed of sweating vary greatly in different situations. Generally speaking, labor intensity, air temperature, humidity, and wind speed are all factors that affect the amount and speed of sweating.

Sweat contains most of the water, more than 99%, and the rest are solid components, mainly sodium chloride (salt and potassium, magnesium, calcium, lactic acid, urea nitrogen, etc.). Sweating is medically divided into warm sweating and mental Sexual sweating. Its central control is in the cerebral cortex and spinal cord. Chinese medicine collectively refers to sweat, tears, saliva, etc. as fluid, and believes that sweating is an important method for diagnosing diseases ^[1]

What's in 100 ml of sweat? 98 to 99% of the ingredients are mainly water, the specific gravity of which is between 1.002 to 1.003, and the pH value is 4.2 to 7.5. Sodium chloride is about 300 mg / 100 ml. 1 2% is a small amount of urea, lactic acid,

Sweating is divided into active and passive. The so-called passive sweating refers to sweating due to sweltering weather and irritable mood. This kind of sweating is a way for the human body to take away heat from the body through water evaporation and maintain physiological activities within the normal range of body temperature. In contrast, the sweat produced by the human body through active movement is called active sweating.

Sweat components can be divided into inorganic and organic components, both of which are metabolites in the body. Inorganic components mainly

Although exercise can shake off some sweat and lose a little weight, be careful of the body's water and electrolytes.

Although sweating is a physiological adjustment, a large amount of sweating and insufficient fluid replacement will cause dehydration and affect health. Lighter

All kinds of "sweat" can be used as one of the diagnostic basis for spying diseases.

Cold Sweat: Whenever a person is sick, frightened, or has an extraordinarily tense mood, or suffers from a physiological or psychological dysfunction, he or she will constantly emit a lot of sweat, which will cause him to feel cold. After sweating, I often feel "worried".

Sticky sweat: sweaty and sticky, thick and hot,

You can capture, analyze, and judge the relationship with sweat from the aspects of sweat color, smell, location, and whether there are accompanying symptoms:

Look at the color

(I) Causes of Onset

Compared with adults, infants and toddlers have larger skin water content, more microvessels on the surface of the skin, more activity, and a stronger metabolism, so more water evaporates from the skin. Furthermore, because the secretion of sweat glands is regulated by vegetative nerves, the neuroendocrine regulating function of the baby is relatively poor, and the inhibitory function of the cerebral cortex on the autonomic nerve is poor. Therefore, the baby's ability to self-regulate cold and heat is relatively poor. The autonomic nerve is still excited even when sleeping at night, so the baby sweats easily when he just falls asleep.

Baby sweats normally

Babies are in the growth and development stage, their metabolism is strong, and they are active and active, so they often sweat more than adults. They are particularly prone to sweating when they are active, have had too much milk, and are excited.

After the cause of sweating is eliminated, the phenomenon of sweating disappears. There is no standard measure of how much sweating is, mainly to see if the baby is sweating at the same time with other accompanying symptoms and discomfort.

Some babies don't like to sweat

The baby does not like to sweat, but the baby usually does not have any abnormal symptoms, which is a normal situation. There is also a rare disease called congenital closed sweat, which is mainly due to dysgenesis of sweat glands or hereditary non-glandular sweat. There is no particularly effective treatment.

Infrequent sweating is harmful to your baby's health and the sweat glands are not smooth. You have lost an important detoxification channel and an important line of defense against disease. Therefore, in accordance with the four seasons and the law of life, it is necessary to sweat when it is time to sweat. Therefore, babies who do not sweat should seek medical treatment in a timely manner.

The effect of sweating on your baby

Since the main component of sweat is water, it also contains a certain amount of inorganic salts and trace elements, so a large amount of sweating has a significant impact on the body's water and salt metabolism, and also has a certain impact on the metabolism of trace elements and vitamins. Sweating babies tend to lose more water, salt and trace elements. May cause zinc deficiency, resulting in decreased blood zinc. Zinc is an essential trace element in the human body. It is closely related to children's growth and development, immune function, vision and sexual development. In the process of children's growth and development, the demand for zinc is relatively large. Mom and dad can add some zinc-rich foods to the baby, such as oysters, lean meat, animal viscera, etc., and can also add some zinc agents, such as zinc gluconate, licorice zinc and so on. In addition, when the baby is sweating for a long time, parents should drink more water to ensure the metabolic needs.

Causes of baby sweating

Medically, the phenomenon of baby sweating is called "hyperhidrosis", which is divided into "physiological hyperhidrosis" and "pathological hyperhidrosis".

Most babies' sweating is a normal physiological phenomenon, which is medically called "physiological hyperhidrosis". Generally, obvious external causes or causes can be found.

Diseases that cause your baby to sweat

Some babies sweat because of illness, and the cause is more complicated. The following are common.

1. Childhood obesity: Obese babies will sweat profusely even if they move or walk normally.

2. Rickets: Hyperhidrosis is an important characteristic manifestation of rickets, usually accompanied by crying at night,

Why do babies sweat more than adults

Occipital alopecia, square skull, anterior cardia enlargement and delayed closure, and more sweating on the head.

3. Cardiopulmonary diseases: Children with congenital heart disease, pneumonia and heart failure often sweat a lot.

4. Tuberculosis: Babies with tuberculosis not only sweat more in the middle of the night, but also sweat more in the middle of the night, which is called "night sweats". It is also accompanied by poor stomach appetite, low or high fever in the afternoon, flushing of the face, weight loss, and some symptoms such as cough, hepatosplenomegaly, and lymphadenopathy.

5. Hypoglycemia: Hypoglycemia should be considered when sweating on an empty stomach. Appears uneasy, pale, cold sweats, even sweating, cold limbs.

6. Drug-induced hyperhidrosis: After taking antipyretics, it causes a lot of sweating.

7. Acute and chronic infectious diseases: typhoid fever, sepsis, rheumatoid disease, connective tissue disease, lupus erythematosus, or hematological diseases, etc., often have a lot of sweating performance, usually ask your doctor to identify.

8. To judge the pathological hyperhidrosis of the baby, in addition to the analysis of the history and physical signs, relevant inspections should be performed in order to make a correct diagnosis and treatment. Parents should not draw conclusions and give the baby random medication. If you find that your baby has the above manifestations, you can take your baby to the hospital for examination in order to make a timely and correct diagnosis.
