How do cell phones effect human health?

I think cellphones are not a big risk to human health. Cell Phones are powered by electricity and magnetic (EMF) Electromagnetic radiation. Scientists say that there are no temperature rise in the brain (hot-spot) because of electromagnetic radiation, and even if there is a hot-spot our body is able to change it back to the regular temperature so hot-spots don't occur. Getting sick from cell phone waves is very rare, only a few are hyper sensitive to the waves. An Australian hospital did a lab experiment and research and they said "Cell phones are not a big risk to humans." The largest study in Denmark show no links to cancer, so there is no possible cancer effect. I think there are no health risks but the most resent study say they don't know but after all this research i think cell phones are not a harmful effect to the human health.

How do cellphones use electromagnetic waves?

In every cellphone there is electromagnetic radiation, it is used to communicate with other cellphones. Without electromagnetic radiation cellphones can not make calls. When you call somebody, it sends out microwaves. A tower picks up the the microwave and sends it to the number you dialed on your phone. The phone you called will then pick up the phone have a conversation. So cellphones use electromagnetic radiation (microwaves) to communicate or send calls and text messages.

Conclusion

I learned a lot about cell phones and electromagnetic radiation, and that even if it does effect your brain it does not do a lot of damage and that nobody knows yet if it is bad for you or if it is good for you. A lot of people did research and they said there is no lead to cancer. So I decided that cell phones are good for you and very useful. They can make you talk with people in a different country or area so in conclusion cellphones are good for you.
