Mobile phones are both good and bad. On the positive side, they help families stay connected and are helpful in emergencies. During power outages when traditional phone service is out, mobile phones may still work. They allow older people to remain independent in their homes because help can be summoned quickly. In addition, people can use them to access important information immediately, such as news and weather.
On the negative side, experts worry that mobile phones cause varying levels of addiction and interfere with personal relationships. They may negatively impact sleep and can lower concentration among children who are distracted by their phones when studying. Studies show that mobile phones can cause anxiety and depression, especially in teens. Bullies sometimes use them as tools to send intimidating messages or embarrassing photos to victims.
Phones can carry bacteria that make people sick. The danger of radiation from mobile phones is not fully understood, but scientists believe such radiation can affect children's developing brains and may even cause brain tumors. Using mobile phones, especially for sending text messages, is extremely dangerous while driving. The Federal Communications Commission reports that more than 10 percent of 18- to 20-year-olds involved in car accidents admitted to texting while driving.
