    Mobile Phones Affect Brain Waves In Bed


    Radiation from mobile phones stimulates brain activity in the early stages of sleep even after you’ve finished using the phone, an Australian study shows.
    Associate Professor Andrew Wood from the Brain Sciences Institute at Melbourne’s Swinburne University says his study also found that exposure to electromagnetic radiation from mobile phones can reduce levels of the hormone melatonin, which is connected to the body’s sleep-wake cycle.
    But the study, reported in the International Journal of Radiation Biology, says it’s premature to conclude that talking on your mobile phone before bed will get in the way of a good night’s sleep.

    The study’s 55 participants received 30 minutes of mobile phone radiation, or 30 minutes of ‘sham’ radiation, on successive Sunday nights before being tucked into bed.
