Why do hair on our body stand erect when we move close to a TV screen etc?i know its static elec. how exactly?

Wizzard is almost right, except for the part about your body being a good insulator except for your hair.  The truth is, most of your body is a good conductor not an insulator.  Water conducts electricity, and since 70% of your body is water, you conduct pretty well.  \n\nSince like charges repel eachother, when your body carries an electric charge, those charges are going to try to separate from each other as much as possible.  They are going to go to the extremities of your body, like the hair folicles on your skin and head, and then they're going to try to separate even more.  Since your hair is very light, even a little charge can be enough to push the hairs apart and make them stand on end.

Lots of skin indicates it is very long when erect. Do not complain.

To help the body in homeostasis of body temperature!Also will stand on end when frightened like a cat but due to evolving to have less hair you just get goosepimples!\n\nWe probably evolved to have less hair due to our ability to produce clothing!Possibly still have head hair as we either didnt produce hats, or it conferred some advantage such as preventing heatstroke(by protecting the back of the neck and forehead)or sexual selection.

You have probably experienced static electricity. It's the charge that you create when you scuff your feet on a rug. Then when you touch a doorknob, you get a small shock. That's static electricity. \n\n    The reason why it works is a little more complicated. To start, you have to know that every object is made up of billions of tiny particles, called protons and electrons. These particles are so small they can only be seen with special microscopes. \n\n    Despite their small size, protons and electrons carry an electrical charge. Protons carry a "positive" charge, while electrons carry a "negative" energy charge. \n\n    Usually, the two different charges balance each other out, and nothing happens. But when two objects with like charges (all positive or all negative) come together, the charges repel and the objects move away from each other. Objects with opposite charges attract each other because the different charges want to enter a state of balance with each other. \n\n    Objects can get a negative charge by picking up electrons from other objects. For example, when your shoes scuff against the rug, your shoes are actually picking up electrons from the rug. The electrons fly over your body, giving you a negative charge. \n\n    Your new electrons fly over your body because they are looking for a positive charge. If you touch a metal doorknob, the electrons on your body will leap into the metal, attracted by the protons there. The transfer of electrons is actually a small electrical current, and produces the tiny electric shock you feel. \n\n    Lightning is like static electricity, except on a much bigger scale. Both lightning and static electricity happen because of the attraction between the opposite charges.

Well, just like they fight fire with fire, you can fight static electricity with static electricity! \n\nWhat you must do is go out and buy a one hundred megavolt Van de Graff generator and bring it home and plug it in. You fire that sucker up and place one hand on the metal sphere and with the other hand, hold on to a metal stair railing or something. Let the machine run for about 15 minutes and get that juice flowing through your body! You may notice your hair standing on end, but don't worry, that's just a normal effect. After 15 minutes, turn the generator off and let go, but continue to hold onto the metal post. All that static electricity will zip out of your body and into that railing so fast, you'll also be free of static clink! \n\nGood luck and have a bright day and have fun with electricity! After all, it does make all our light bulbs work!!\n\nIf you can't afford a van de graff generator, YOU MIGHT WANT TO TRY AND INCREASE THE HUMIDITY LEVEL IN YOUR HOME ENVIRONMENT (ie PLACE OPEN CONTAINERS OF WATER ON OR NEAR ROOM HEAT SOURCES) SINCE IT DOES SEEM STATIC ELECTRICITY IS MORE PREVALENT IN DRIER CLIMATES.

It could very well be due to shaving, but mostly it sounds like an irritation of the hair follicles.  Clothing rubbing in that area (especially not protected with hair) will cause friction.  The hair folicles are then irritated.

Pubic hair is like parsely.  Its a decoration that you push aside before you eat.

Static charge is deposited on the surface of the CRT during the operation of the TV. So your tester glows because of the electrostatic potential existing between your hand and the surface of the CRT. \n\nThe voltage, and the current resulting through our body when we touch it are too weak to cause us any harm. All the same, you do notice your hair standing on end don't you?

The closths are all rubbing against each other in the drier. And they are made of different materials (polyester, cotton, nylon and blends). While they are still wet, any electricity built up from the rubbing in the drier is dispersed through the water and the positive and negative charges short out, leaving a net of zero. \n\nBut as they dry, it gets harder and harder for the electrical charge to 'flow' and it just accumulates on different fabrics. More positive on some, more negative on others. And since this charge cannot easily flow, it's called 'static electricity'. And the postive charge on one peice of clothing attracts the negative charge on another and they 'stick'.

Static electricity! Your hairs were probably positively charged while the chair was negatively charged.

I get goosebumps on the backs of my hands and my cheeks. They may not be as noticable in those places if the skin is coarse, but they still occur, at leat on my body. YMMV.\n\n\nEdit:\n\nAll you people syaing that you have no hair on the tops of your hands, your feet or your face. I guess that's possible but you do realise that you are in a distinct minority, right? Most people do have hair on the backs of their hands, their feet and their faces. We even have a special name for the hair on men's faces, we call it beard.\n\nSo lack of hair can't be the answer.

Anatommically speakiing, hair grow ooon parts of the body which are more sensitive to heat e.g. head/scalp, armpits. This one of our bodies protection from. Another function of the hair is protection of the skin from friction, specially in the genital area, during coitus or sex. \n\nSo male and female pubic hair has purpose. shaving it would expose the skin to friction which may lead to chaffing, etc.

Just let it grow. It protects your sensitive area and keeps it warm. Bald is soooo 1990s! Porn stars still remove all the hair for the pervs, but real women have hair.

First you have to know "Static electricity" is not electricity which is static. \n\n"Static electricity" is all about charge-imbalance, and it has nothing to do with charges at rest. "Static electricity" was misnamed.\n\nWhen we scuff our shoes upon a rug on a dry winter day, our bodies typically charge up to a potential of several thousand volts with respect to the ground. In physics this is a well-known fact, and is easily verified by meter measurements. Touch a grounded object, and a spark will leap between the object and your fingertip. This kind of electric spark can only exist when a high voltage is present. The tiniest spark requires about 500 volts. Big, nasty, painful sparks require lots more voltage, up to several thousand volts. But even when no sparks are jumping, there is still a high voltage between your charged body and the ground, and your charged body is surrounded with an invisible electric field.\n\nThere are many way you can eliminate it, Refer to this web you can will able to know.\nhttp://www.school-for-champions.com/science/staticcont.htm

You've heard of a person's hair standing on end when they are frightened or otherwise emotional? You've seen how an animal's hair stands up when cornered or when cold? For humans, although most parts of our bodies don't have much hair anymore (well, most of us), the goosebumps occur where the hair follicles used to be and they are trying to make those hairs stand on end. When you're cold the same thing happens because standing hair is a better insulation than hair laying down.

Static electricity is caused by electrons being removed from a body, such as you. when this body is not an electrical conductor, it becomes ion charged.Once that body is ionically charged other bodies which are opposingly charged are attracted.

There are several hypotheses, one is that it the hair traps scent or pheromomes and may have been useful for attracting a mate in the past. Another is that it reduces friction when moving the arm.  Yet another is that it is just vestigial body hair.  Be interested to see what others suggest.\n\nRegards
