New Delhi:

A latest study led by a group of researchers from University of Houston in the US, has found that blue light, emitted from various digital gadgets like smartphones, tablets and computer may excessively affect the quality of your sleep. While in an age of digitisation people cannot even think of spending a single day without their ultra-smart devices, the study has warned them and further advised to help own self a little to get rid of such harmful practices.

The study suggests that most of the LED-based devices release such kind of damaging blue light which dictates our body when to sleep boosting alertness and regulating the clock of our internal body.

Activating photoreceptors namely ntrinsically photosensitive retinal ganglion cells (ipRGCs), this artificial light suppresses melatonin, the hormone that signals your body that it is time to sleep.

Talking about the same Lisa Ostrin, assistant professor at University of Houston in the US has said, "The most important takeaway is that blue light at night time really does decrease sleep quality. Sleep is very important for the regeneration of many functions in our body."

The days long study, published in 'Ophthalmic & Physiological Optics' was conducted on 22 participants and further discovered that wearing short wavelength-blocking glasses three hours before bedtime for two weeks may increase the quality of your sleep even after continuing the same digital habit in night.

During the study all the participants, aged between 17 to 42 were advised to do the same and quite surprisingly results showed about a 58 per cent increase in their nighttime melatonin levels.

"Those levels are even higher than increases from over- the-counter melatonin supplements," Lisa was quoted further while talking about the same.

After going through the process for weeks all the participants even experienced a better sleep. According to Ostrin all the candidates are falling asleep faster than before and there is also a considerable increase in the duration of their sleep at night.

Limiting screen time, applying screen filters, wearing computer glasses that block blue light and using anti-reflective lenses are also considered to be some powerful ways to offset the effects of artificial light at nighttime. Some latest devices are also having night mode settings in order to limit that blue light exposure.

"By using blue blocking glasses we are decreasing input to the photoreceptors, so we can improve sleep and still continue to use our devices. That is nice, because we can still be productive at night," Lisa Ostrin stated further.
