There have been multiple thoughts about how cellphones affect your health. Like that they cause cancer and that that the effect your sleep .

A few years ago at the University Of Ohio a study took place looking at the the effects of cellphones on sleep. Between the ages of 18-39 they used their phones for a mean of 46.6 minutes per night. It deduced that:

• Media use might make it take longer to fall asleep (2).
• Media use might mean less time spent sleeping, thus reducing sleep (3).
• Bright light emitted by electronic devices might impact sleep quality (4).
• Light exposure might be temporarily activating you.

There is one massive rumour involving cellphones and health that has been disproven. Its that cellphones cause cancer. Earlier this year scientists did a study with rat, they exposed them to radiation. The result was actually the rats dying later.
