Blue Light May Lead to Insomnia, Study Spending too much time on your digital devices, including smartphone, tablet and laptop leads to severe sleep problems, a study says. The researchers of the University of Pennsylvania say that people who use their smartphone in the bed, take a longer time to fall asleep. Blue light emitted from the screens of digital device unbalances melatonin hormone levels in the body. More than 30 percent people of the total population in the world experiences sleep problems in a row due to hormonal imbalance.
A reputed online pharmacy, Sleeping Pill UK conducted a survey, the number of people who buy sleeping tablets in the UK, the US and other countries in the world has been increased by 200 percent in the last two decades. According to sleep experts, longer screen-time is associated with poor sleep quality, i.e. the blue light spectrum emitted by digital devices can decrease the production of melatonin hormone in the body. Low levels of melatonin in the body cause severe sleep problems. What is Melatonin? Melatonin, known as sleep hormone, helps people to fall asleep and stay asleep during the night, if the levels of melatonin hormone decrease, it leads to decreased drowsiness and nonrestorative sleep. To stay active and creative, restorative sleep is very important, i.e. REM sleep phase improves IQ, memory and keeps the people energetic, healthy and more productive in their daily life. The study reveals that if a bright blue light is close to people’s eyes, it has excessive influence on the levels of melatonin, i.e. the levels of melatonin suppressed by about 25 percent. People
