| Nail polish dryer can cause cancer |
San Diego: A new study warns that the machine used to dry nail polish can cause cancer.
Researchers
from the University of California, San Diego, found in a study that the use of
nail polish dryers can lead to the destruction of human cells and changes in
cells that cause cancer.
According to experts, despite being extremely harmful to health, these
ultraviolet nail lamps are sold without thinking about the possible dangers. Ludmil
Alexandrov, a professor of bioengineering and cellular and molecular medicine
at the university, said that these devices are sold as safe, that there is
nothing to worry about, but no one has yet tested these devices and the human
cells they affect. did not study
Professor Alexandrov and his colleagues observed reports published in several
medical journals that people who regularly had gel manicures, such as beauty
pageants or beauticians, now developed certain finger cancers. He said that the
research showed that there was zero information about what these devices were
doing to human cells.
Ultraviolet rays, which have wavelengths shorter than the wavelength of visible
light, are further divided into three types by wavelength, UVA, UVB, and UVC.
Generally,
the LEDs used in UV nail lamps emit wavelengths between 340 and 395 nanometers.
In
the study, the scientists used cells taken from mice with two types of human
cells.
In one
method intense irradiation was applied, while in the other method the cells
were irradiated for a fixed period of time after a longer period of time.
In the first method, a variety of cells placed in Petri dishes were exposed to
radiation for 20 minutes, then removed from the lamp for an hour to recover or
return to their original shape, and again exposed to radiation for 20 minutes.
while in the second method the cells were placed under the machine for 20
minutes daily for three days.
The researchers found that a single 20-minute session caused 20 to 30 percent
cell death, while 20-minute sessions for three consecutive days resulted in
between 65 and 70 percent cell death.
