If genius is really 1% inspiration and 99% transpiration, then some of us need to be much smarter than others. While sweat is a normal human function, a few lucky ones seem to produce more than normal amounts – especially in the hot summer months . But before you plug in air conditioners all season, there are a few things you should know about sweat. Here are the basics, what it is, why it happens (for some people more than others), and what you can do if you are worried.
There are three types of sweat
No sweat is created equal, says Laure Rittié, PhD, a research associate at the Department of Dermatology at the University of Michigan. And everyone sweats differently: some people may have problems with all three types of sweat, while others can really only perceive one or two.
First there is body sweat ̵
Then it sweats on the palms and soles of the feet. This type of sweat helps to increase grip and grip, says Rittié and evolutionarily it is the body's response to a perceived threat. (That's why some people notice it when they're feeling anxious.) "If you want to hold on to something, you're better off with wet fingers," explains Rittié . "We did not wear shoes at the beginning, so sweaty feet helped us walk or climb."
There is sweat that comes out of the armpits and the genital area. This is the type that produces so-called body odor thanks to the bacteria that live in these places. "We are not quite sure what the function is here, but we think that there is a kind of pheromone communication," says Rittié . "If a person in a herd feels danger and starts giving off those strong smells, they could warn others around them."

Sweating a lot That does not mean you're out of shape.
The body begins to produce body sweat when it begins to heat – either from the outside, from high temperatures or internally, from muscle exertion (as in sports). So, if you push harder than your body is used to, your body will tend to step on its internal air conditioner; That's why a well-trained athlete is able to run a 10-minute mile without sweat, while the same workout leaves a less-conditioned person red-faced and drenched.
But the more you exercise your body and the more time you spend in hot, humid climates, the more efficient you become while sweating. "The body will adjust a little earlier and react before it gets too hot," Rittié says, "so your sweating will be spread over time and throughout your body instead of building and letting go immediately, and leaving a big spot on your shirt. "
Yes, sweating altogether can mean that – just look at some NBA basketball game and you'll see even highly trained athletes sweat a ton – But it's a good thing after all. It means that the body can respond better to the demands of heat and movement, keeping it cooler.
How much sweat is largely determined before the age of two
Whether one sweats buckets or stays fresh like a daisy on hot days has a lot to do with genetics. "If one or both parents were heavy sweaters, then there's a fair chance you'll do that," says sports physiologist Michael Bergeron, PhD, president of youth sports in America. Men also sweat more often than women, he says, though that's not always the case.
Body composition also plays a role: Larger people generally sweat more because they work harder to carry a heavier load. "But many comparatively small people can sweat enormously," says Bergeron. And because muscles create heat, he adds that people with more muscle mass also sweat more than their leaner counterparts.
But in fact, much of what a person sweats depends on their first two years of life. Then the sweat glands are activated first, says Rittié ; If they are not fully turned on during this time, they will probably never do so. In other words, a super-active toddler who walks around in the heat will probably develop more sweat (again, a good thing) than one who is not very active.
Heavy sweaters should hydrate more
"The more sweat you have, the more aware you must be of replacing the water your body has lost," says Bergeron. In sports, most adults can comfortably and safely take about 1.5 liters of water per hour. If you sweat more than that amount – you can weigh yourself before and after training to find out – you should make amends by drinking extra water before and after exercise.
Sweat also contains important electrolytes, such as sodium, that the body must work properly. Most people get enough salt in their diets that they do not have to worry about it, but if you exercise for more than an hour and sweat properly, an electrolyte-enhanced sports drink can help replace lost material.  Rittié also points out that getting your body acclimated to training or heating – so you do not sweat in the end – does not pay off if you do not drink enough water on a regular basis. "If you stay hydrated before and during exercise, you train your body against the heat," she says. Cold water is best, she adds, "because it helps to cool your internal organs."

Prescription Treatments Can Help
Staying in shape, wearing sweat – washing clothes and spending two to three weeks in order to stay fit There is not much that can be done to combat sweating during exercise. (Applying antiperspirant to the hairline or other parts of your body can help reduce local sweating – but Rittié warns you if you block sweat glands in one part of the body; others compensate for it by working harder.)
People with excessive Day – Today's sweating – a condition known as hyperhidrosis – can have more options. If you already use an over-the-counter aluminum-based antiperspirant and you do not cut it, your doctor may recommend a prescription solution containing aluminum chloride. These work best when applied at bedtime, but may cause skin and eye irritation in some people.
Botox injections and certain medications have been shown to block nerves that trigger perspiration under their arms or on their hands and feet. Friction also contributes to sweaty feet, says Rittié, so changing your shoes and socks – and making sure you do not slip into them – can help [iftheydonotworkconsiderelectro-stimulationorevensurgery If sweating actually causes a problem in your daily life, talk to your family doctor or dermatologist about possible solutions. Otherwise, grab your water bottle and go outside. Embrace your sweaty self and try to be grateful that your body is doing its job.
