Using Ipads Before Bed

From the British newspaper "The Daily Telegraph"

     This article is about how people are using devices like Ipads, Tablets, and others before bed. It says that it is stoping users from getting any sleep. Because the room is dark when people are using them, the brain tells the body that it is time to go to sleep. But the light from the devices are stopping that pattern. The brain still thinks that it is still daytime when the bright blue light is shinning in the users face. The bright light is kindof mocking the daylight from outside. The longer the light is shinning in the users face and the brighter it is, the longer it'll take for the person to got to sleep.
    "Neurologists have known for years that staring at screens late in the evening can disrupt sleep – be they television screens, computer screens or mobile phone screens." The article says. "However, because cell phones and tablets are by nature portable… more people are taking them into the bedroom."
     People who do research at the Lighting Research Center, In New York at the Rensselaer Polytechnic Institute, are saying that looking at a device for a really long time “leads to a suppression of our natural melatonin levels as the devices emit optical radiation at short wavelengths.” Which means that they emit the blue light. They say that if you are to use them at night, set the light down some. Make sure that it is not too bright and that it won't effect your sleep.
     Even though sleep can be affected in this case, other things can be affected too. You can risk getting breast cancer and obesity.
    This can also affect people who already have sleep disruption problems and those who have normal sleep patterns. This could not affect me because i dont use these things before bed or in the dark with high light. I usually turn the light down because the light will usually hurt my eyes if im in the dark. If you do not want to have a poor night's sleep everytime you use these portable devices, start by turning down the brightness on them.
