Statistics from Canada show that among Canadian teenagers aged 12- 19, 6 1% have mobile phones, and many children even use mobile phones to "make phone calls". The popularity of mobile phones does facilitate children's communication, but the radiation generated by their wireless communication is also silently devouring children's health. To this end, many countries have issued an appeal: keep mobile phones away from children. More and more children use mobile phones. Among American teenagers, 3 1% send at least 100 short messages every day, and 15% send more than 200 short messages every day. Everyone sends an average of 50 text messages every day.

Destroy the nervous system. Research in the British magazine Microwave Theory and Technology shows that the skull thickness of children is obviously lower than that of adults, and the absorption rate of radiation is obviously higher than that of adults. Early education experts told reporters that the child's nervous system is in the development stage and the potential threat is even greater. A test by clermont-ferrand University shows that when children use mobile phones, their brains absorb 60% more electromagnetic waves than adults. Recently, the British "Daily Mail" even wrote that children's use of mobile phones can cause health problems such as memory loss and sleep disorders. Dr. Gerard Kaidu of the University of Warwick in the United Kingdom warned that cell phone radiation would destroy the normal function of children's nervous system, which would lead to a series of problems such as memory loss, headache and poor sleep. Affect growth and development. Early education experts pointed out that high-dose electromagnetism is not only harmful to children's growth and development, but also brings diseases such as asthma and leukemia. According to experts, children are in the stage of growth and development, and the water content in body tissues is richer than that of adults. The more water, the greater the damage to organs.
