Are mobile phones really harmful? Do they
have a harmful effect on our body? These are few of the questions which we have
been asking and have been asked since their invention. And till today
researches are being conducted to specify whether they really affect our health
or not?
As we all know mobile phones convert radio
waves into electrical signals in order to send and receive our communications. And
to let you know, the power use range is at its peaks when it is turned on i.e. between
0.1 and 2 watts. The radio waves that mobile devices rely on are at the
non-ionizing end of the electromagnetic spectrum. Now, while we use a mobile
phone close to our body a very small amount of energy from the radio waves is
absorbed and is converted into heat.
Research
into mobile phones and their radiations
Many scientific researchers have concluded
that a temperature rise of approx one degree Celsius is a safe level for the human
body. Our normal biological processes cool us down and also prevent any
significant temperature rise in our bodies. Also, a vast majority of experts including
the World Health Organization (WHO), agrees that mobile phones and cell phones operated
in line with international guidelines, do not produce enough energy or heat to
cause the long-term change in the human body.

| mobile radiations and its effects |
There have been several studies and
researches throughout the world on mobile radiations and its effects on human body. So, before we head forward it is
very important to understand that there is a big difference between a
biological effect and a health effect.
For instance, radio frequency or the commonly
known RF radiation from a cell phone has the biological effect of raising the
temperature of the human brain by a fraction of a degree. And this biological
effect doesn’t automatically carry any health risks as our body is well-equipped
to deal with very wide variations in temperature without experiencing any harm
from them.
Mobile phone
uses, cancer and other possible health effects
Now as the RF radiations are a form of non-ionizing
radiation, they cannot cause cancer. There is no other known biological way which
could suggest that RF radiation could be carcinogenic. While there are several
other researches being carried on whether mobile phone use causes cancer or
other health problems, no negative health implications have yet been found till
date.
Precautions
to reduce mobile phone radiation exposure
Although evidences so far suggest that mobile phone uses aren’t harmful, but
long-term risks and consequences are yet to be clarified. So if you feel
concerned then you can reduce your exposure to mobile phone RF radiations
by-
·
Selecting a
mobile phone which has a low specific absorption rate (SAR), which refers to
the amount of RF radiation absorbed by body tissues
·
Using a
landline connection or phone, if possible
·
Talking less
on mobile phone or through keeping your mobile calls short
·
Using a
hands-free kit. It is one of the best options.
·
Not carrying
your mobile phone close to your body
Lastly, here are a few things to remember-
·
The current
international consensus is that mobile phones don’t cause cancer or promote the
accelerated growth of existing tumors.
·
Cancer can
take many years, even decades, to develop.
·
Using a
mobile phone while driving significantly increases the risk of traffic
accidents.
On a closing note, mobile phones do radiate radio frequency but they are
very weak in order to create any harm to our body. They might be harmful in a
long run but with few simple steps or considerations, you can easily use a
mobile phone without any worry.
