O que faz você suar?

O suor excessivo pode ser extremamente incômodo e até acabar com a vida social de uma pessoa. Se você acha que é o seu caso, não hesite em procurar um médico, saiba que o nome dessa doença é hiperidrose, e já existem tratamentos para acabar ou manter sob controle o problema. Enquanto isso, vamos dar uma olhada no que nos faz suar?

Calor e umidade

Quando a temperatura sobe, suas glândulas sudoríparas (cerca de 2,6 milhões delas) entram em ação, produzindo a transpiração. O suor é o jeito natural do seu corpo se manter refrescado. Parte do suor evapora da sua pele, levando junto o calor. O resto escorre pelo rosto e pelo corpo. Nos sentimos com mais calor quando está úmido por que o ar já saturado dificulta a evaporação do suor do corpo.

Ficar bravo pode causar suor

Quando você fica com raiva, seu corpo chega a seu ponto de ebulição, liberando hormônios que aumentam a freqüência cardíaca e pressão arterial e aumenta a temperatura corporal, o que pode levar a um aumento do suor. Se essa raiva for muito freqüente, cuidado, pode ser sinal de algum problema mais grave.

Exercícios Físicos

Suar, suar e suar é um jeito de saber que você está aproveitando bem o seu exercício. Como você perde muitos líquidos durante o exercício físico, não esqueça de se manter bem hidratado, antes, durante e depois. Isso ajuda a manter a temperatura do corpo e ajuda na performance também.

Estar sob pressão

Todo mundo que perdeu um prazo no trabalho ou ficou mudo diante de um público sabe o quanto stress, ansiedade e vergonha podem fazer você suar. Stress emocional especificamente ativa as glândulas sudoríparas da palma das mãos e sola dos pés, o que pode tornar aquele aperto de mão meio constrangedor quando você está nervoso.

Febre

Quando estamos doentes, nosso cérebro aumenta o termostato do corpo em alguns graus. Sentimos frio e calafrios enquanto o corpo aumenta sua temperatura para tornar o “ambiente” menos hospitaleiro para os germes. Quando o aquecimento começa é que o suor entra em ação, sua função é ajudar o corpo a se refrescar e voltar para uma temperatura normal.

Outras doenças podem nos fazer suar

O suor não é necessariamente um sintoma de febre, pode ser o caso de doenças mais sérias, como angina e até de um ataque cardíaco. Infecções, diabetes, e hiperatividade da glândula tireóide também aumentam o nível de suor do corpo. Por isso um acompanhamento médico é sempre fundamental.

Café

Aquela primeira xícara da manhã pode ir além de te ajudar a acordar, ela também pode te ajudar a começar a suar! O café aumenta a transpiração de duas maneiras. Primeiro, a cafeína estimula o sistema nervoso central, ativando as glândulas sudoríparas (quanto mais cafeína você consumir, mais poderá suar). Segundo, o próprio calor da bebida por fazer o seu corpo sentir mais calor, causando o suor.

Comidas apimentadas

Quando você dá aquela primeira garfada naquele prato super apimentado não parece que tem um incêndio na sua boca? Esses alimentos enganam seu corpo, fazendo com que ele ache que está com calor, pois estimulam os mesmos receptores nervosos que respondem a essas situações de calor.

Menopausa e as ondas de calor

Durante a menopausa, os níveis excessivos de estrogênio enganam direitinho o hipotálamo – o responsável pelo controle da temperatura do corpo. Não importa o calor que está lá fora, uma onda de calor vai fazer com que eu corpo ache que está no meio do deserto do Saara. Em uma tentativa desesperada de eliminar o excesso de calor, os vasos sanguíneos se dilatam e as glândulas sudoríparas disparam a todo vapor.

Cigarro

Eis outro motivo pra deixar de vez o cigarro de lado: fumar pode fazer você suar! A nicotina faz com que o corpo libere o químico acetilcolina, que estimula as glândulas sudoríparas. Também aumenta a freqüência cardíaca, a pressão arterial e a temperatura corporal. Estar em abstinência de nicotina também aumenta o suor, mas se você agüentar por tempo suficiente para largar de vez o hábito, vai valer a pena: diminuirão suas chances de ter câncer, enfisema e várias outras doenças fatais.

Remédios e seus efeitos colaterais

Ainda que sirvam para fazer com que você se sinta melhor, alguns medicamentos podem ter seus próprios sintomas. Suar pode ser efeito colateral de vários remédios, incluindo antidepressivos, anti-inflamatórios, medicamentos para a pressão e tratamentos para o câncer e diabetes. Se for o seu caso, converse com seu médico. Talvez uma alteração na dose ou até uma troca de medicamento resolva o problema.

O amor.. ah, o amor..

Você pode achar que é coisa do coração, mas se apaixonar começa mesmo no seu cérebro, com uma descarga de hormônios do amor que se assemelham muito à adrenalina. São eles os responsáveis pelo coração acelerado, mãos suadas e outros clássicos sintomas físicos que indicam que você está perdidamente apaixonado.

Gravidez

Os hormônios que tomam conta do corpo durante a gravidez e uma aceleração do metabolismo pode fazer você sentir mais calor que o habitual e deixar suas glândulas sudoríparas mais ativas. Cuidado duplo nessa hora: beba bastante água para se manter e manter o bebe bem hidratado!

Heat and Humidity

When the temperature rises, your sweat glands (some 2.6 million of them) spring into action, producing perspiration. Sweating is your body’s natural way of keeping you cool. Some sweat evaporates from your skin, taking heat with it. The rest runs down your face and body. You feel hotter when it's humid out because the already saturated air leaves less room for the sweat to evaporate off your body.

Getting Mad Can Cause Sweating

When you get angry, your body reaches its boiling point, releasing stress hormones that increase your heart rate and blood pressure and raise your body temperature, which can lead to sweating. Anger is a healthy emotion once in a while, but when you regularly lose your temper, it could signal a problem.

Exercise Makes You Sweat

Breaking a sweat is one way to tell that you're getting a good workout. Because you lose fluid when you sweat -- especially when it's hot -- you need to stay hydrated. Remember to hydrate before you work out in addition to while you’re working out and after you are done. This will help with body temperature and performance, too.

Being Under Pressure

Anyone who's missed a big work deadline or choked up in front of an audience knows how stress, anxiety, and embarrassment can make you sweat. Emotional stress specifically activates the sweat glands in the palms of your hands and soles of your feet, which is why it can be embarrassing to shake hands when you're nervous.

Fevers

When you're sick, your brain raises your body’s thermostat a few degrees. You’ll feel cold and have chills as your body raises its temperature to make it a less welcoming place for germs. When your fever breaks and your thermostat resets itself back to about 98.6 degrees, you’ll feel hot and start to sweat. The sweat helps to cool you off back to a normal temperature.

Feeling Sick Can Cause Sweating

Being sick can make you sweat, and not just because you have a fever. Sweating can be a symptom of angina -- heart-related chest pain -- and a heart attack. Infections, diabetes, and an overactive thyroid gland all can make you sweat. Some diseases, like cancer and HIV, can cause night sweats. If you're sweating a lot and are concerned, see your doctor.

Coffee

That morning cup of Joe will do more than wake you up -- it can also make you sweat. Coffee increases perspiration in two ways. First, caffeine stimulates the central nervous system, activating sweat glands (the more caffeine you drink, the more you sweat). Second, the heat from the drink itself can make your body feel hot enough to sweat.

Spicy Foods Can Cause Sweating

When you bite into a double-jalapeno burrito, why does it feel like a four-alarm fire has just erupted in your mouth? Spicy foods fool your body into thinking it's hot by stimulating the same nerve receptors that respond to heat. That's why a plate of hot wings or bowl of spicy soup can make your tongue sizzle and your face break out in a sweat.

Menopause and Hot Flashes

During menopause, plunging estrogen levels play tricks on the hypothalamus -- the body's temperature gauge. No matter how frigid it is outside, a hot flash will make your body think you're in the middle of a heat wave. In a desperate attempt to shed excess heat, the blood vessels in your skin dilate and your sweat glands go into overdrive, leaving you feeling flushed, sweaty, and yearning for a cold shower.

Too Much Alcohol

You can tell right away when someone's been throwing back a few too many drinks. He’s wobbly on his feet, slurring his speech, and his face is flushed and sweaty. The sweatiness is due to an alcohol effect called vasodilation -- widening of the blood vessels in the skin.

Smoking

Here's another reason to stamp out that cigarette: Smoking can make you sweat. Nicotine causes your body to release the chemical acetylcholine, which stimulates the sweat glands. It also raises heart rate and blood pressure and body temperature. Nicotine withdrawal also causes excess perspiration, but if you can sweat it out long enough to kick the habit, you'll lower your risk for cancer, emphysema, and dozens of other deadly diseases.

Sweating Can Be a Medicine Side Effect

Though they're meant to make us feel better, some medications can cause their own symptoms. Sweating may be a side effect of several drugs, including antidepressants, nonsteroidal anti-inflammatory drugs (NSAIDs), blood pressure medications, cancer treatments, and some diabetes drugs. If your drugs are making you too sweaty, talk to your doctor about changing your dose or switching to another drug.

Love Can Make You Sweat

You might feel like you've lost your head, but falling in love actually starts in your brain, with a rush of adrenaline-like "love chemicals." These are responsible for the racing heart, sweaty palms, and other telltale physical signs that you're smitten.
