When sweating is normal, and when - no. Check if everything is okay with you

It is believed, though sweat outside the treadmill or, say, the gym - indecent. Moisture allegedly indicates a lack of proper hygiene. Do not support this nonsense!

Sweat - great (almost always) on whichever of syllables in the word "great," you may have put the emphasis. Another issue is that sweating - a multi-faceted phenomenon that has both obvious advantages and disadvantages. And all these mathematical signs worth considering. Start over.

Where does the sweat

Sweating is primarily physiological mechanismMechanisms and controllers of eccrine sweating in humans. About the same as the one that causes the eyes to blink hard and tears, if they hit the dust; skin - to respond to the emergence of ultraviolet tanning; stomach - to produce acid by ingestion of food it ...

Pot - part of the thermoregulatory system. It stands out as the corresponding parts of the brain (called the thermoregulatory center) record rise in body temperature or ambient temperature.

At such moments, the autonomic nervous system sends a signal: "It seems that we burn!" Sweat glands receive a nervous pulse, causing them to shrink rapidly ducts, absorbing moisture from the surrounding tissue and discarding it out. This forms the sweat on the skin surface. then it evaporates. This process reduces the temperature of the skin, and with it, thanks to the bloodstream, and the body as a whole.

On the surface of the body unevenly distributed between 2 and 4 million sweat glands. Their concentration is higher in the armpits, in the inguinal folds, on the hands, feet and face.

Sweating is necessary for everyone. Insufficient sweating (anhidrosis) when, for whatever reasons, sweat glands on the skin surface tolerate too little moisture, can be fraught with superheat and heat stroke.

Excessive sweating (hyperhidrosis), from a physiological point of view is not that scary, but it brings a serious psychological distress. Which is particularly unpleasant when perspiration surplus more and smell.

Why do people sweat, even when it is not hot

Increased sweating in hot weather or with fiznagruzki, in general, predictable and understandable. Thus, by reducing the temperature extra moisture evaporation from the skin, the body responds to overheating. However, there are conditions under which the temperature rise is not, and excessive sweating - is. Such sweat appearing without overheating, called cold.

The reasons that we throw into the pot without overheating, can be quite varied. Here are some common options.

1. Strong emotions or stress

About the unconscious defensive reaction "fight or flight" Layfhaker already I wrote. Strong emotions and experiences of our brain interprets as a signal of impending danger and mobilizes the body: and suddenly will have to join with someone in battle or flee?

Even if you're not going to fight with the boss or run with planorki, your body is still preparing for the increased activity. Preventive sweating - one of the elements of this training. Suddenly you will tear the enemy too quickly and immediately overheat? "Well, no-oo", - says the sympathetic nervous system and starts the process of thermoregulation in advance, awarding looks absolutely quiet you wet palms and sweaty backs.

2. Eating spicy food

Work sweat glands dramatically enhanced by the use of rich spices (mustard, horseradish, red and black pepper, curry, onion, garlic, coriander, ginger...) dishes. Also covered in sweat we often make alcohol. This type is called sweating food perspirationSweating (Normal Amounts): Causes, Adjustments, and Complications.

3. some diseases

Sweating often accompanies diseases associated with an increase in temperature. For example, acute respiratory infections, flu, sore throat, all kinds of infections. Suddenly the projecting cold sweat may be a side effect, in particular:

1. Hypoglycemia (drastic reduction in blood sugar levels).
2. Reception of synthetic thyroid hormones.
3. Reception of certain types of painkillers, including morphine.
4. All kinds of pain syndromes.
5. Cancer.

By the way, an important clarification! Be sure to go and see a therapist, if coupled with heightened sweating you observe the following symptoms:

1. Chest pain.
2. Severe dizziness.
3. Difficulty breathing.

They may indicate serious heart problems.

It is also an occasion for a mandatory consultation with a physician is constant sweating, do not stop for a day or more.

4. Smoking

In addition to other unpleasant effects that has on our body nicotine, he is also stimulating8 reasons you sweat production of acetylcholine. This chemical compound including forces actively working sweat glands. A lot of smoke - more sweat. Communication here is unambiguous.

5. For women - pregnancy or menopause

Hormonal fluctuations associated with child-bearing child and menopause are also often accompanied by increased sweating. This is a natural process.

Why sweat smells

The sweat glands are not the same. There are two kinds of them, which form the sweat fundamentally different composition.

The eccrine glands

Actually thermoregulation elements. They make up about 75% of the sweat glands are located all over the body and are active from birth. Sweat produced by them is colorless and odorless, because 99% of water. On the surface of it is excreted through special ducts that look like tiny pores.

Under normal conditions the eccrine gland is output approximately 0,5 liters of water daily. However, at heat, physical activity, stress and so on sweat volume may reach 10 liters a day.

It is thanks to the eccrine sweat children, even if they are worn in the heat and are dripping wet, easily can do without anti-perspirant and shower during the day. Function thermoregulatory sweat system fulfills perfectly, but it absolutely does not smell. How different the situation with the following view of the sweat glands ...

apocrine gland

They are about 25% of the total number of sweat glands. They are larger than eccrine, and are located only on strictly defined areas of the skin: in the armpits and groin folds, forehead and scalp. Apocrine glands become active only after reaching puberty.

Made of moisture is discharged to the skin surface does not directly, as in the case of eccrine glands, and hair follicles. So, up the hairs on the skin acts apocrine sweat - milky white sticky liquid, which, in addition to water, contains impressive dose fats, proteins, hormones, volatile fatty acids and other organic compounds.

It is believed that this type of sweat largely determines the specific smell of each person. By the way, another name apocrine glands - glands sexual odor.

mixing with bacteriaLiving on the skin surface, becoming for them a good breeding ground for nourishing apocrine sweat (if it is not washed off) becomes a sharp odor.

But even if you take a shower every 20 minutes, from the sexual odor you do not get rid of. At least until then, until the age reproductive function begins to fade, passing "closing" apocrine glands.

What to do to not sweat

... Or at least not as much sweat. The issue date, especially during the warm season. And the answer is generally contained in the information given above.

Completely get rid of sweat you can not: at least half a liter of normal evaporate from your skin anyway have every day. When the heat and active physical exercise, infectious diseases of the amount of moisture naturally growing, and this should rejoice, not prevent: the evaporation of sweat allows your body to function in the normal temperature mode. The only action that it is important to take in such situations - is to drink more water to prevent dehydration.

The rest of the management of perspiration requires primarily correct lifestyle and daily habits:

1. Wear breathable clothing that will not be hot.
2. Avoid stresses and excessive emotional reactions.
3. Remove from the diet and Beverages, activates the sweat glands.
4. Quit smoking.
5. If excessive sweating cause you used drugs or existing disease, talk to your doctor about alternative treatments.
6. Use antiperspirants and do it correctly.

And remember: sweating - your friend, not an enemy. Treat this physiological features carefully and with gratitude.
