It's no surprise. Everyone relies on their gadgets to connect them to the Internet and do anything: writing reports, research, purchasing something online or simply connecting to loved ones across the globe.
Some, however, think this is too much as people have a tendency to overuse these devices, starting as early as 6 in the morning to the wee hours the next morning just to check their social media accounts, emails and messages on their free texts/calls apps.
According to an article on BBC, a leading doctor said that there should be an automatic "bed" or sleep time mode for all smartphones and tablets. The setting should filter out the blue light according to Professor Paul Gringras, as this light delays the body clock and ultimately makes people stay awake much later than the average bed time.
He added that gadget manufacturers should be more responsible when they put a new product out in the market. He explained that with every new model of the phone it becomes bluer and brighter as well, and making it harder for users to sleep early in the process.
At night, a hormone is being produced by the body, it is called Melatonin or the "sleep hormone" which helps the body to start feeling sleepy and eventually fall asleep.
A study that was published Frontiers in Public Health said that there are some wavelengths of light especially the ones from the blue and green that can disturb the system, added Professor Gringras. The research concluded there was a clear trend for new devices to be bigger, brighter, have higher levels of contrast and emit more blue light. He said some sleep-aware apps had already been designed to reduce blue-green light emissions.
Prof Gringras added: "It's not good enough to say do less and accept this is the world we live in, they're fun devices but we do need some protection on what they do at night-time."
