Technology and your Health

    I have believed for a while that mobiles, mobile phone masts and another technology is harmful to our health, due to the exposure of radiation. Scientists at the very least think mobile phones should be used as little as possible. They think it is better to be cautious about using mobiles and a lot of scientists believe they are harmful to your health. Mobile phones are particularly bad for children. The phone companies will tell you that they are safe. But remember they are selling a product so they are hardly going to put you off buying their product by telling you it is unsafe. Where there is a lot of money involved there tends to be corruption. So don't think that they or the government, who get a tax of the money from the use of masts and mobile phones that are put up, have your best interests in mind.

   After all people said that smoking, asbestos, a medication called Thalidomide, pesticides and so on were either safe or wouldn't cause you serious harm. However they were wrong as they caused cancer, disability and terrible illnesses.

    I think technology will be to the next generation what drink, smoking and drugs have been to previous generations. In fact research claims mobile phones could kill more people than smoking.

    Wireless (wi-fi) can cause headaches, nausea, tiredness and memory loss in some people. Technology can be particularly hazardous if you are sensitive to it. We have so much technology now there is 24 hour television, computers, Nintendo games, phones and so on. It is not just mobiles but Dect phones (cordless) too and on top of all this there is wireless as well.

    Electrical gadgets in the bedroom can also cause sleep problems. It is best to have no electronic items in your bedroom. But if you can't do without them at least make sure you don't have a computer, cordless phone or mobile in your bedroom or at least make sure that are turned off. Cordless phones emit a high amount of radiation this is because they have to be on all the time so that the phone can be charged up. If you didn't do this the phone wouldn't work. So keep your technology use to a limited amount of time each day. Particularly keep your use of mobile phones to a minimum and use a landline instead, because mobile phones can cause cancerous brain tumours if they are used for a long period of time over the years.

    Always remember that your health is very important as you might find you are unable to return to good health once you have lost it.
