Poor Night Sleep

     In the article "Using iPads before bed' can lead to a poor night's sleep" posted by Daily New Article researchers say that using tablet computers like Apple's iPad and Samsung's Galaxy note just before bed can lead to a poor night sleep. This may seem weird but there is a certain light from the devices that cause anyone who uses the devices before they go to bed then you will have a poor night sleep. This is because more and more people are (using) their tablets...to surf the web, check Facebook, Twitter and other social networks, before switching the light of to go to sleep. But researchers are warning that the blueish light from the devices. This light mimics daylight convicing the brain that it's daytime.

  But any light can make anyone hard to sleep. Especially if it's a very bright light, the brighter the light and longer the exposure, the more difficulty it will cause in falling asleep. 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. However , because cell phones, laptops and tablets are portable now people take them to their bedrooms when it's time to go to bed and stay up all night on their device. When the person gets into the  bedroom with the light off then have thier cell phones , laptops or tablets the light is the only bright light in the dark room , this means it would be harder to go to sleep.


   Researchers at the Lighting Research Center, at the Rensselaer Polytechnic Institute in New York, are warning that looking at tablet displays for more than two hours “leads to a suppression of our natural melatonin levels as the devices emit optical radiation at short wavelengths” – in other words, they emit bluer light.They say: “Although turning off devices at night is the ultimate solution, it is recommended that if these devices are used at night displays are dimmed as much as possible and that the time spent on them before bed should be limited.”

Does this mean that iPod, iPad , laptop or tablet companies will stop making their devices?
Or will companies make the light on the devices much lower?
