The relationship between mobile phones and sleep

A study suggests that using a cell phone before going to bed can make your sleep much worse. Research is sponsored by mobile phone companies (mobile phones). The results show that radiation from handheld devices can cause insomnia, headaches and confusion. It also reduces the amount of deep sleep and reduces the body's ability to relax.

The study was conducted by the Swedish Karolinska Institute and Wayne University, USA and sponsored by the Mobile Manufacturers Forum. The survey was conducted on 35 males and 36 females aged 18 to 45. Some people were put into radiation environments similar to when using cell phones, others were placed in the same environment but were only paid. Radiate ' pretend '.

People with radiation often take longer to be able to enter the first stage of deep sleep and have shorter periods of deep sleep.

Scientists conclude: ' The process of exposure to wireless signals at 884 MHz in the laboratory, the components of sleep play an important role in restoring the severely affected body. . '

Professor Bengt Arnetz, a member of the research team, said: 'This work really demonstrates the use of mobile phones in connection with certain changes in some areas of the brain responsible for activating and regulating stress systems. . '

A hypothesis is that radiation may interfere with the production of melatonin, controlling the body's internal circadian rhythms.

About half of the people who participated in the study believed that they were " sensitive " and reported symptoms such as headaches, impaired cognitive ability by using mobile phones. However, they are not sure if they are exposed to radiation during the test.

Alasdair Philips, director of Powerwatch, which investigates the effect of electromagnetism on human health, said: 'More and more evidence urges us to consider this issue with care, research. indicates that if people want to make phone calls in the evening, it is better to use a fixed line and don't let your cell phone close to you. '

Mike Dolan - CEO of the Mobile Operators Association said the work was in conflict with many other works.'This is only a very small piece in the vast scientific world, a small effect that a scientist can compare with less harm than a cup of coffee.'

Last September, a six-year study by the Mobile and Health Telecommunications Research Program (MTHRP) concluded that using mobile phones did not cause short-term risks to the brain. However, scientists say they are still unsure about the possibility of high cancer due to long-term use.

In the UK, mobile phone service operates in the band 872-960 MHz, 1710-1875 MHz and 1920-2170 MHz.
