As the sun sets, social networks become more active, Internet traffic spikes up, a lot of people get hooked to their smartphones and end up staring at the screen till late in the night.

Sure, Evening is the perfect time to see catch that funny video on YouTube, have a group chat with your friends or calmly read an e-book on Your phone or tablet. But that color rich screen is causing more damage than just dry eyes.

Research has shown repeatedly that exposure to blue light at night has adverse side effects on our health. Let me elaborate.

Visible light contains a wide range of wavelengths(Colors). Exposure to blue light considerably reduces secretion of melatonin, the sleep hormone. As the sun sets, blue light diminishes, cutting off out visual contact with shorter wavelength. Then starts melatonin production which helps us catch a night of sound sleep.

  • Inhibited production of melatonin resulting in a shorter and a shallow sleep.
  • Unwanted changes in your natural circadian rhythms. (sleep-wake rhythm that impacts many other body functions.)
  • Disturbed circadian rhythms and poor quality of sleep has been shown to adversely affect immunity, which can lead to enhanced vulnerability to diseases.
