Smartphone users have been worried about their health for many years. Not because of neck pain or insomnia caused by increased cell phone use, but because of the question of whether the radiation from the devices poses a health risk.

Many people are particularly concerned about a possible increased risk of cancer. But now a Long-term study by the World Health Organization (WHO) provided the answer.

No increased risk

The result: Over the last twenty years, there has been no connection between the use of smartphones and the risk of developing tumors. The focus of the study was primarily on the frequency of brain tumors, leukemia and other types of cancer such as salivary gland cancer.

Using a meta-analysis of more than 5,000 studies, the researchers wanted to find out whether different frequencies, such as those from radio or television, but also Wi-Fi or smartphones, can lead to an increased incidence of cancer.

No significant differences were found between people who use smartphones intensively and those who use them little or not at all. Radio or television stations and mobile phone stations did not increase the risk either.

Studies that specifically examined the effects of 3G and 4G networks were also consulted. There were not enough reports on 5G networks, but in general there was no effect from comparable frequencies such as radar.

Suspicion of health damage persists

In addition to the allegedly higher cancer risk from cell phone radiation, there have been numerous other speculations in recent decades about how smartphone use is harmful to health. It is also said to have a negative impact on fertility, cause depression or even make people fat because the radiation can stimulate the appetite.

None of these concerns have been confirmed by comprehensive, reliable studies. There have only been indications and assumptions based on small groups or individual cases. A general caution towards new technology certainly also plays a role, as does conspiracy belief about electromagnetic fields, which are said to have frightening effects on people.

The researchers say that current radiation protection standards are sufficient to protect public health, but studies are still being conducted to examine the long-term effects of radiation on people of all ages.
