Scientists studied 35 men and 36 women aged between 18 and 45. Some were exposed to radiation that exactly mimicked mobile phone radiation; others were placed in precisely the same conditions, but without radiation exposure.

The research showed that using the handsets before bed caused people to take longer to reach deeper stages of sleep and and in shorter intervals. Exposure to 884 MHz wireless disrupted sleep periods that involve the body’s ability to repair damage suffered during the day.

The sleep disturbance can lead to mood and personality changes, ADHD-like symptoms, depression, lack of concentration and poor academic performance, grouchiness, difficulty concentrating, and hyperactivity and behavior problems in children.

About half of the people in the study believed themselves to be “electrosensitive”, with claims of symptoms such as headaches and impaired cognitive function from mobile phone use, but they proved unable to tell if they had been exposed to the radiation in the test.
