Why does hair stand up on a cold, dry day?

In the dry weather like this, many people often “quick heart” when suddenly seeing an electric shock crackling when accidentally touching metal objects, pulling blankets, turning on electrical switches … or just suddenly “touch.

According to experts, this phenomenon is called electrostatic phenomenon . And the fact that you got that “electric shock” is because you got that electrostatic shock.

Static electricity occurs due to an imbalance of charges on the surface of a material.

Static electricity is a phenomenon that occurs due to an imbalance of electrical charges on the surface of a material. In fact, the electric charge that accumulates on the surface of an object along with the resonance of the friction process can cause static electricity.

In fact, the electric charge that accumulates on the surface of an object along with the resonance of the friction process can cause static electricity.

When two materials come into contact, electrical charge transfers from one to the other, resulting in an excess of positive charge on one object, and an excess of negative charge on the other.

Humans can feel an electrical imbalance while wearing or pulling clothes, combing their hair with a plastic comb, or some other rubbing action.

The human body is also a very special electrochemical machine, so it can generate a microscopic amount of electricity, enough to cause a slight numbing sensation when accidentally friction with something.

That is also why when you accidentally touch a metal doorknob, the negative charge on the body will continue to increase until enough to produce a weak amount of electricity to allow a charge between the hand and the hand. The doorknob suddenly flashed, feeling a little numb.

Hair stands on end on dry days.

The weather temperature in winter and autumn often has very low humidity, leading to dryness and easy generation of static electricity. Moreover, hair does not have the ability to regenerate itself, it is made up of dead cells like nails, so when damaged hair is not able to maintain moisture and repair itself. When the hair’s moisture is lost, the dry climate causes the hair to generate static electricity.

According to researchers, water is a good conductor of electricity. Moisture in the air will help move electrons out of the human body before they accumulate too much, causing static electricity.

You may not expect it, but static electricity generated by hair does not mean that static electricity is only generated in hair. Static electricity has a tendency to travel into small spaces . Therefore, static electricity generated when clothes rub against each other will also be transmitted through the body up to the hair.

According to the researchers, static electricity mostly occurs in cold weather because the air at this time often lacks the moisture needed for static electricity to maintain balance.

On the other hand, the hot air between is more humid, which is also why electrostatic shocks are less common in the summer.

In addition, some materials often cause static electricity such as rubber, nylon, synthetic fiber, hair, fur, metal, …

In winter, the humidity in the air is quite low. Using a nebulizer, humidifier, etc. at home will help reduce static electricity, crackling explosions when there is friction between people and objects.

Items with synthetic fibers such as polyester, nylon can easily lead to very good static electricity. Therefore, people should use clothes with natural fabrics such as cotton.

Taking care of your skin, especially applying hand cream, will help your hands retain proper moisture. Maintaining and increasing skin moisture is a great way to avoid static electricity in dry weather conditions.

This type of paper helps prevent electrical charges from being transferred to the body. (Photo: Internet).

Dryer sheet has a similar design to tissue paper but is thinner, has the effect of softening the fabric, helping to balance the charge during the drying process and preventing the accumulation of electrical charges transmitted to the body.

Rubber shoes are strong insulators, increasing the potential for static electricity when you accidentally walk across a wool or nylon rug. Choosing leather shoes will be more suitable in this weather.
