What is ultraviolet radiation?

Ultraviolet rays have different types and reach humans during the day from various natural and unnatural sources. The most important natural source of ultraviolet rays is the sun, which produces three different spectrums of these rays. Artificial sources of ultraviolet rays include the following:

Solarium or solar device
UV lamp for nail planting
Mercury vapor lamp
Some laser devices
Halogen lamp
Fluorescent light
Dental light cure device

Types of UV rays

The different types of ultraviolet rays based on their wavelength include the following:

UVA with a wavelength of 315-399 nm

Ultraviolet A rays make up more than 95% of the ultraviolet rays entering the earth.... This ray has a longer wavelength and therefore has less energy.... Ultraviolet A rays can contribute to the occurrence of skin cancer due to penetrating the dermis layer of the skin...

UVB with a wavelength of 280-314 nm

Ultraviolet B has a shorter wavelength and more power than ultraviolet A.. This radiation affects the outer layer of the skin, i.e. the epidermis.... In this way, it can cause burns and dangerous types of skin cancer such as severe melanoma.

UVC with a wavelength of 100-279 nm

Ultraviolet C rays have the highest amount of energy among different types of ultraviolet rays.... But this radiation is absorbed by the ozone layer and therefore does not enter the Earth's atmosphere.... Ultraviolet C rays are produced through artificial methods such as lasers.

Benefits of UV rays

Although ultraviolet rays can endanger human health, they also have benefits....Ultraviolet rays cause the body to produce vitamin D....As you know, vitamin D is an essential substance for calcium and phosphorus absorption and helps in bone growth....The World Health Organization recommends 2-3 exposures to sunlight for 5-15 minutes..

Some laser devices with low and safe amounts of ultraviolet rays Purple makes the skin more transparent. In addition, ultraviolet rays are also used in nail implant devices. However, note that ultraviolet rays weaken nails and should not be used excessively.

The use of ultraviolet rays for disinfection is due to its antiseptic properties.... The effect of ultraviolet rays on bacteria causes them to be deactivated and destroyed.... For this reason, it is used in hospitals and infectious disease centers to disinfect surfaces.... For example, ultraviolet rays are used in the operating room to disinfect the environment.

Phototherapy or light therapy is a method of treatment using ultraviolet rays that is used in the treatment of rickets, psoriasis, eczema, vitiligo and lupus... The use of the therapeutic dose of ultraviolet rays should be done with the opinion of a specialist doctor. Regarding phototherapy treatment, you can consult the skin and hair specialists at GCORP LLC.

Consequences of UV rays

The disadvantages of UV rays are:

Ultraviolet rays are carcinogenic for the skin, and ultraviolet rays A and B are the most effective factors in the occurrence of skin cancer and squamous cell cancer.
Ultraviolet rays cause sunburn... If you see its symptoms, you should see a dermatologist.
Exposure to ultraviolet rays increases the risk of eye problems such as pterygium, cataracts, inflammation and corneal irritation.
Ultraviolet rays cause premature aging, leathery skin and facial wrinkles.
The risk of solar elastosis, liver spots and actinic keratosis increases due to UV rays.
Ultraviolet radiation weakens the body's immune system in dealing with harmful factors and increases the risk of infection and inflammation.
Ultraviolet light activates the latent herpes virus.
Ultraviolet radiation reduces the effectiveness of vaccines.

Is UV radiation in the phone harmful?

Ultraviolet radiation is also produced from electronic devices such as phones, tablets, computers, and televisions.... In this way, people who work with electronic devices for a long time are exposed to this radiation.... Note that the amount of radiation produced in mobile phones and tablets is not high, but if used continuously, it can be harmful.... In addition to creating ultraviolet rays from these devices, they also reflect the ultraviolet rays of the sun.. The person's face and eyes and the risk of contracting They increase cancer and injuries.

UV radiation in pregnancy

Ultraviolet rays affect pregnant women more, because women's body systems are very sensitive during this period... That's why doctors advise pregnant women to avoid exposure to artificial and natural sources of ultraviolet rays as much as possible.

Ultraviolet rays can stimulate the progesterone hormone and lead to melasma or pregnancy spots.. Melasma can develop in most parts of the body and remain for a long time after pregnancy... Heatstroke, dehydration, fetal defects, folic acid deficiency, increased body temperature and increased risk of brain damage in the fetus are among others.

What is the range of UV rays?

According to international standards, the permissible index of ultraviolet radiation is between 0-2, and this value is known as the safe index of ultraviolet radiation.. Higher indices are determined as follows:

Index 5-3: Low risk
Index 6-7: Dangerous
Index 8-10: high risk
Index 11-12: very dangerous

Note that each person receives a different amount of UV rays daily due to the following factors:

Using or not using sunscreen
Degree of exposure to sunlight and artificial sources of ultraviolet rays
Using long or short clothes
radiation power

What are the harms of ultraviolet rays in nail planting?

The duration of using ultraviolet rays in nail planting is short and usually does not result in any special complications.. but excessive use of these rays brings the following complications:

Premature aging
Skin cancer

To avoid these side effects, be sure to use sunscreen cream with at least SPF 50 on your hand skin 20 minutes before use... Note that the use of this device is not recommended for pregnant women.

Methods to protect the body against UV rays

You can protect yourself from the effects of UV rays by following these tips:

Be sure to use sunscreen with a suitable SPF.... It is recommended to use sunscreen both indoors and outdoors... Because ultraviolet A rays pass through the glass and affect your skin even indoors.
Be sure to use a brimmed hat in the summer season.
Use prescription sunglasses that protect 100% of the eyes from sunlight.
It is better to wear long sleeve clothes so that the skin is not exposed to direct sunlight.
Do not expose yourself to natural and artificial sources of ultraviolet radiation for a long time.
Try not to leave the house between 10 am and 4 pm.

Concluding remarks

In this article, we have explained about the advantages and disadvantages of ultraviolet rays.... Ultraviolet rays have many uses in our daily lives, and if used in the right amount, there will be no complications.... The important thing to know about preventing the effects of ultraviolet rays is to follow the preventive recommendations.... Regarding diseases caused by the effects of ultraviolet rays, you can go to GCORP LLC visit in person or consult online with a skin and hair doctor.
