Nowadays, we use digital devices in many ways, such as waking us up in the morning, listening to music, communicating with friends and so on. But studies have found that overuse of electronics can affect our sleep, our study and work.

     To help people take a break from their always-on lifestyles, America set the National Day of Unplugging in 2010 to encourage people to put away their electronics for 24 hours, which is on the second Friday of March every year.

     Without any doubt, many people find that the unplugged day seems longer than a typical day. “Without my phone, my breakfast was too short and I did not know what to do next,” one participant of last year’s unplugging experiment wrote. Another shared his grief at not being able to look at his phone during bus and train rides, calling the day”the longest time of my life”.

But others see the experiment as a way to experience what life was like before the rise of electronics. “My friend and i has dinner in the evening, and we both discussed about how much more present we felt-- how we could hear what each other was saying,” one participant wrote.

   Although living without electronics seems impossible in today’s world, unplugging from time to time allows people to slow down and reflect on life. “At the end of the day, I was missing neither social media nor having a digital connection,” one participant noted. “I note. “I was happy for the opportunity to challenge my unhealthy daily habits, because this gave me the opportunity to discover a slower, clearer way of life.”
