Whether it is your work, commute, family time or even when sleeping at night, smart phones are never far away from you. Over exposure to the smart phones can be harmful in many ways.

The radiations from smart phones is a subject matter of scientific studies. Although, there are no conclusive studies on direct correlation between smart phone usage and diseases. But, national advisory authorities in Austria, France, Germany & Sweden have recommended measures to minimise smart phone usage. Some of these recommendations are:

1.Use hands-free to decrease the radiation to the head.
2.Keep the mobile phone away from the body.
3.Do not use telephone in a car without an external antenna.

The national authorities in several countries have also recommended moderate usage of mobile phones for children. The radiations emitted by cell phones can be harmful in the long run & pose a health risk for humans.

As per US National Center for Biotechnology information, Scientists have reported adverse health effects of using mobile phones including changes in brain activity, reaction times, and sleep patterns.

SAR stands for Specific Absorption Rate. It is the rate at which our body absorbs energy when exposed to radio frequence or electromagnetic field.
Prolonged exposure to radiations may cause cell damage and other issues, which could affect a person.
