What electromagnetic waves do cell phones use and how do they affect human health?

Cell phones use radiofrequency electromagnetic waves to transmit and receive signals. The impact of these waves on human health is a topic of ongoing research and debate. Some studies suggest a potential link between long-term exposure to radiofrequency waves and health issues such as cancer, while others argue that the evidence is inconclusive. It is recommended to limit exposure to cell phone radiation by using hands-free devices and keeping the phone away from the body when not in use.
