Is setting down your iPad the last thing you do before bed? New research shows that all of those nighttime hours spent with your tablet can wreak havoc on your sleep.

Technology is currently evolving at a rapid pace. Tech-savvy consumers are requiring the latest access to information and instant methods of communication through portable devices to keep up with the needs of a growing mobile society. In addition to the functions of work, play, and socialization, it’s no wonder that educators are also using technology as a mobile learning tool across the globe.

We think of all the rituals at bedtime from yoga, essential oils, and sound machines when sometimes the one issue stems from American’s largest addiction: digital devices.

With 71 percent of Americans sleeping with their phone in bed or on the nightstand, the blue light from the screens can emit unneeded light that prevents our brains from shutting down. But we should also not be confused with eliminating blue light altogether. Light therapy treats seasonal affective disorder (SAD) uses blue light.

Ever wonder what makes the sky blue? It is blue light from the atmosphere and comes in a natural, non harmful way. According to Blue Light Exposed, “when outside, light from the sun travels through the atmosphere. The shorter, high energy blue wavelengths collide with the air molecules causing blue light to scatter everywhere.”

Most of us have a routine we follow. We get up at the same time, go through the same steps to get ready for the day, and even have the same thing for breakfast. There are many reasons we follow routines. We may do it out of habit, or do it because it’s comfortable, or maybe it’s the most effective and efficient way to go about our days. Our habits and routines can even make us more successful according to an article recently published in the Harvard Business Review.
