The Dhaka Times Desk A group of researchers from a university in the United States found that people who look at mobile phones and computer monitors at night have sleep problems.
Researchers have found that phones and tablets emit a type of blue light; That stops the brain from producing melatonin. Melatonin is the substance that prepares our body for sleep. When the production of melatonin stops, the signal reaches our brain that it is not yet time to sleep!
The researchers observed 635 adults for 30 days to conduct the study published in the journal Plus One. It has been found that they spend an average of 3.7 minutes every hour with their smartphones. This included 136 people who were found to have trouble sleeping when they were looking at too much screen.
Researchers believe that if you look at a smartphone or tablet for one minute, sleep can be delayed by one and a half minutes!
