why is it that you get sweaty under the HOT sun even though you're just standing there not doing anything?
153489
The sun is radiating heat which is absorbed by your body and clothes.  The body tries to maintain a consistent internal temperature of around 98.6 degrees.  As your body and clothes absorb heat energy from the sun, your body will attempt to compensate for this additional heat by causing your skin to perspire.  As the perspiration evaporates off of your skin, it carries away some of the heat from your body, thus lowering your body temperature.

Some people have this problem both in their palms and the sole of their feet.  If it's really bad you do have the option of surgery to remove some or all of the sweat glands in these areas.  Otherwise, you can try using a little body powder/talc in your palms before you play your instrument or do other stuff.  Do your palms sweat because you are nervous?  If so, try to work on relaxing when you are nervous.

Your metabolism is slowing down, so heat builds up in your body more. When you sit down, all that "insulation: makes everything sweat more than normal.\n\nDo daily aerobic and squats exercises. The problem will go away.

EVERYONE SWEATS A DIFFERENT AMOUNT DURING EXERCISE. SWEATING VERY LITTLE MAY BE NORMAL FOR SOME PEOPLE. A BETTER SIGN THAT ITS A GOOD WORK OUT IS IF YOU FIND TALKING AS YOU EXERCISE A LITTLE DIFFICULT, THEN YOUR GETTING A HEART PUMPING, MUSCLE BUILDING WORK OUT.

Basically your body becomes very warm, which causes vasodilation of  your blood vessels. Meaning your blood vessels "expand" thus there is less flow to your brain, hence your lightheadedness. If you sit in a really hot tub for 30min and then quickly stand up and jump around,  you might even pass out.

when you stand in the sun and get warm, it is because your skin absorbs the electromagnetic radiation we call light.  light is both a wave and a particle - called a photon.  photons have no mass, but they do carry energy.  when the photon is absorbed by your skin, the light energy is converted into (mostly) heat energy.\n\nanyway, it should'nt make a difference whether you are moving or not.  strictly speaking there are a few effects to consider but i would think they are very small.  for example:\n\n - the further you are from a light source, the dimmer it appears, and therefore the less light you absorb.  so if you are running away from the sun and you have a fixed effective area, then on average you will receive less solar flux than if you are just standing there.  however this is a tiny amount in terms of moving around on the surface of the earth.\n\n- conceivably if you are moving away from the sun, there will also be an effective doppler shift of the light, which will (slightly) shift the solar spectrum into the red.  since redder light has a lower energy, you should effectively absorb less energy, but the absorption spectrum of the skin should be considered.  also unless you are the flash, this effect will also be tiny because humans run so slow.\n\nthe energy that you DO absorb gets carried away from your body by several mechanisms:\n\n - radiation:  you (and all things) radiate light energy in the infrared.  this is called "blackbody radiation" and is a function of your temperature.  (blackbody radiation is why hot things glow orange, for instance.)\n\n - evaporation:  your skin sweats, and the sweat evaporates.  this evaporation requires some heat, which effectively cools down your skin.\n\n - conduction:  if you are standing perfectly still in air that is not moving, your body will warm up a layer of air molecules around your skin.  this warm air will rise, and cooler air will move in to replace it.  this is actually probably why it *feels* like you're cooler if you're running around: more wind = more cool air = more heat loss.

hi bonny\nnothing is worng it is only because u don't drink water enough.\nDuring workout i think you  take lot of break in between  sets... which brings down  heart rate and cools down your body so you don't sweat this is one of a reason...\n\nOR you maybe working in aircooled GYM which is another reason

No. the skin is actually the largest organ of the human body and when you sweat you are excreeting waste. This is a very important function of the excretory system and without sweating you could become very sick. Also, sweating is a sort of thermostat. When you get too hot the body sweats, the air hits the water(sweat) and causes your body to feel cooler. So, it's very normal to sweat when it is hot. Now a lot of people sweat more than others and they are actually better off than people that sweat very little. What is important is to shower daily to get the impurities and bacteria off your body from the sweat. This can cause infected sweat glands, hair follicles and just body odor in general. \nNow, exfolliation is a form of removing the outer layer of skin from your body, a lot of girls and women do it to their faces believing the old layer of dead skin cells make you look old. Actually a daily cleansing of the face is really good enough. Witch hazel is cheap, is a natural asstringent and has a PH balancing effect on the face and the pores on the face keeping it in good condition. So it has nothing to do with sweat. Good luck.

If you are talking that it feels cooler to you, it is because it evaporates moisture that is on your skin and that makes it feel cooler. Even if you are not sweating to where you can see the moisture, it is there.

On body regulates it's heat through persperation.  It's not as much the temperature that makes it feel hot as the humidity.  The higher the humidity the less moisture evaporated from the skin thus reducing the cooling effect.

because your body is resting and you burn less energy. Burning Energy = Heat. \n\nk1

Its just your body's reaction to arousal (by that I mean stress or excitement) If you sweat excessively, try a product called DRICLOR, you should be able to get it in your local chemist. (you apply it the night before and it completely stops you from sweating - armpit area anyway)

Agree with one poster, could it be menopause. Even if young you can be pre-menopausal. A blood test will determine that. \n\nWhat is your salt intake?  The body gets rid of salt thru prespiration.\n\nRead following article from WEBMD.COM:\nHeavy Sweating\n\nWhy do I sweat so much? By Lewis P. Stolman, MD\n  \n\n\n\n\nNov. 6, 2000 -- The problem you describe is called hyperhidrosis, or excessive sweating. And yes, there's lots you can do. \n\n\nSweating, of course, is perfectly normal. It's one way the body maintains its temperature. We sweat when it's hot or when we've been exercising vigorously. And when the moisture produced by perspiration evaporates, it cools the skin, and therefore the core temperature of the body. \n\n\nBut sometimes this nifty system goes awry. As many as one in 100 people suffer the kind of problem you're having: When they're under stress, the sweat starts flowing, usually on the palms, soles, face, and armpits. \n\n\nFor whatever reason, some people can undergo extreme stress and not sweat at all. Others find themselves drenched in perspiration from just having to say a few words at a meeting. We don't really understand why one person's threshold for sweating is different from another's. But we do know that the tendency to sweat under stress sometimes runs in families. \n\n\nIf you find yourself sweating all the time, and all over -- not just on your palms, soles, and underarms -- it may be a sign of a serious illness like tuberculosis, some kind of cancer, or thyroid disease. Talk to a doctor immediately. \n\n\nFortunately, most people who sweat heavily under stress aren't in any danger. But they may feel quite embarrassed, and the problem can get in the way of their careers. I've treated artists who can't work because their palms get too sweaty and musicians who have trouble playing their instruments. \n\n\nHow do you stop it? The simplest remedy is an antiperspirant, which can be used on hands and feet as well as in the underarm area. Over-the-counter versions work well. If these don't prove strong enough, you can ask your doctor for a prescription-strength version. And if that doesn't help, your doctor may suggest a tranquilizer (such as Valium) for those special occasions when you know you're likely to be extra nervous -- a job interview, some kind of public speaking, or even a first date. \n\n\nIn particularly stubborn cases, we may have to try other approaches. One option is surgery to remove sweat glands in the affected area. Another is to inject small amounts of Botox -- botulinum toxin -- to block the nerves that trigger sweat glands. This treatment must be repeated every 6 to 8 months, however, and the injections can be painful, especially in the palms and feet. Finally, if all else fails for sweaty hands, a surgical procedure may be performed to sever the nerves to the affected sweat glands. However, this is a serious operation that carries with it the risk of complications. \n\n\nIn my experience, the simplest and most cost-effective way to turn off the faucet is a treatment called iontophoresis. This involves applying a low-level electrical current to the affected area, which essentially blocks the sweat duct. For many patients, a one-time treatment may control excessive sweating for good. \n\n\nThe bottom line: Don't worry too much if stress leaves you with sweaty palms and damp circles under your arms. Make the right moves and you can stay dry. You shouldn't have to sweat it forever. \n\n\nLewis P. Stolman, MD, is associate professor of pediatrics at the University of Medicine and Dentistry of New Jersey and a member of the Dermatology and Laser Center of Northern New Jersey. He recently published a review of treatments for hyperhidrosis in the journal Dermatologic Clinics, October 1998.

I don't think you do sweat. Sweating is your bodies cooling mechanism, and if you're not overheated, then you probably won't sweat. When your body gets hot, it sweats so the air can make it evaporate off of you and cool you down, but if your not in the air to have it evaporate, I don't think you would sweat. Plus the water would be sitting on top of all your pours and sweatglands so the sweat couldn't really come out anyway.\n\nI dunno, just a guess. I'm not a Bio person or anything. Would it even matter if you did sweat? It would just mix into the water anyway? lol!

First, in the grand scheme of things, you are not that much closer to the sun. Do this: stand up, then shuffle your feet about a half inch to the left. You didn't move much - that's about how much closer you are to the sun.\n\nSecond, while you are correct about the warm air rising and the cold air sinking, you are forgetting the main factor that affects the heat we have on Earth - the ground. It is such an amazing heat keeper and releaser. The ground will radiate heat up towards us. However, it will cool as it goes up, which makes it, you guessed it, come back down for another round of heating. \n\nThird, in general, the higher you go, the less dense the air is, which also means it can not hold much water. Therefore, there isn't much humidity to help hold and retain heat, making it feel colder.\n\nHope these answers get you on your way to answering your question!

Hi! My palms get sweaty at times too. -___-\n\nWhat I do is to wash my hands as often as possible and dry them. \n\nDoesn't seem much but hope that helps.
