Researchers are injvestigation weather ordinary use of cell phones cause health problems.
Getting a phone call from a friend when you are sick can act just like a steaming bowl of chicken soup .It feels good just to know that someone cares .but if your phone is a cell phone its possible that all chitchat may itself cause some health problems.
Normal phones are harmless because they transmit sound as electrical pulses through those wires that hang from poles or snake through pipes or tunnles undergound .Cell phones use a different strategy .Every word you speak into a cell phone becomes a digital massage that gets sent out into the air as pulses of microwave radiation .
Some people worry that letting all that radition pulse across your brain can cause serious health problems including cancer. Now scientists in sweden repoirt evidence that radiation from some cell phones kills brain cells in rats .
The researchers exposed adolescent rarts to low levels of cell phone radiaton for 2 hours .Fifty days later up to 2 percent of cells in the rats brains were dead or dying the scientists report .
No one’s sure what this means for people .No other studies have so far uncovered significant health effects in animals or people and others scientists have yet to confirm the swedish results .Just in case however it might be wise to keep your calls short and to use a handsfree headset to increase the distance between you and your cellphone.
