As soon as mobile devices appeared, the debate about their impact on the human body did not subside. Scientists are conducting a lot of scientific research. Back in 2001, a ban was introduced in Europe on the sale of toy cell phones and on the use and advertising of phones for minors. In 2011 the WHO (World Health Organization) has classified the radiation from cell phones in group 2B as possibly carcinogenic to humans, but after 2 years has announced that no adverse effects to humans have been identified.
At this point, it is definitely established that the harm is related to the electromagnetic radiation that the phone creates around itself. The same radiation is around any device powered by the mains. However, the phone is close to our head. Children are the most sensitive to electromagnetic radiation. Their bones, in particular the bones of the skull, are thinner and block harmful radiation to a lesser extent.
To assess the harmful effects of "cell phones" on the body, a special index was introduced - the specific absorption factor of electromagnetic energy (SAR). It shows how much electromagnetic field energy (in watts) was absorbed by one kilogram of human body in one second. SAR is the first thing you should ask about when buying a new cell phone by looking at the instructions that come with it. If the SAR is less than 0.2 W/kg, the phone has very low irradiance. It is low if it is between 0.2 and 0.5 W/kg, and medium if it is greater than 0.5 but less than 1.0 W/kg. The irradiating ability is considered high for the units with SAR exceeding 1.0 W/kg. Unfortunately, no unified method of determining this coefficient has been developed in the world so far, so the results of identical studies carried out in different laboratories differ significantly from each other.
Effect of electromagnetic radiation on the human brain
The negative effect of electromagnetic radiation on the human brain is the heating of brain tissue. This can lead to chromosomal changes in brain cells, their mutation and, consequently, the emergence of brain tumors.
How does mobile electromagnetic radiation affect children?
A child's organs are formed throughout their childhood. Exposure to electromagnetic waves can disrupt their development. Exposure to radio waves can affect a child's mental and physical well-being. Some studies have proven that cell phones can cause sleep disturbance, lethargy, sleepiness, decreased immunity, memory impairment and mental disorders. The main manifestation is irritable weakness syndrome. In young children, it is expressed in caprice; unstable mood and emotional intemperance - in older children. Sleep becomes disturbing, with unpleasant dreams. It is difficult for the child to fall asleep, but it is also difficult for him or her to wake up in the morning. Often there is excessive excitement in the child before going to bed, sometimes changing into tears and fears. Children of preschool age are characterized by excessive excitement.
School-age children begin to experience difficulties in learning, the child becomes absent-minded, it is difficult to maintain attention and concentrate. It becomes difficult for the child to remember something new, and he or she begins to forget what he or she already knew. Children complain of frequent headaches. The child can't sit still, he is constantly moving his hands and shoulders.
The so-called child nervousness is the mildest form of neurasthenia. Its characteristic features are increased fatigue, emotional instability, a tendency to tears and caprices, sometimes night terrors (the child wakes up, cries, calls for parents). Fear of the dark and loneliness can occur.
At what age is it okay to use a cell phone?
For many parents, a cell phone in their child's possession is a guarantee of his safety and their peace of mind. After all, thanks to the "cell phone" the child is under the constant control of his father and mother. However, health must come first. It is necessary to postpone the purchase of a cell phone for your child as long as possible. Sociologists believe that the most appropriate age for using a cell phone is from ten years old.
If parents believe that their baby needs a phone at an earlier age, they should make sure that phone calls are as short as possible. The best way out of this situation is considered one-way communication on the child's phone. In other words, parents can call the child, but the child cannot.
Experts of the American Academy of Pediatrics and the Canadian Pediatric Society suggest not giving gadgets to children under two years old. Children under the age of 12 can be given a tablet, but it should be strictly limited in time. According to pediatricians, children under 2 years old should not interact with gadgets at all.
For children 3 to 5 years old the time on gadgets should be limited to 1 hour per day. From 6 to 18 years old, you can play no more than 2 hours a day. Child psychotherapists believe that many p
