It is often a key role in causing poor sleep. As quoted from Dailymail, according to Professor Charles Czeisler of Harvard artificial lights on these devices can interfere with the body's natural rhythms and affects chemicals in the brain and encourage people to use stimulants such as caffeine to awake longer.
Written in the journal Nature, the professor of sleep medicine at Harvard Medical School are called to carry out the research. This research is to help develop ways 'behavior and technical' to counteract the adverse effects of artificial light on modern sleep patterns.
According to Prof. Charles decrease the number of hours of sleep per night affect public health, including a greater risk of obesity, diabetes, heart disease, depression and stroke in adults and concentration problems in children. While it is known all electric light affects circadian rhythms (body clock naturally) and sleep, exposure at night on LED lights like those in cell phones and computers are 'usually more disturbing "than the standard electric light bulb.
"There are many reasons why people do not get enough sleep in the 24 hours a week, from early start at work or school, or long commutes, up due to food and beverages rich in caffeine," said Prof. Charles. Besides Prof. Charles reveals that triggers the electric lights are often not considered.
"Without it, only a few people who will be using caffeine to stay awake at night. And light affects circadian rhythms was more powerful than drugs," he said. Prof. Charles added between 1950 and 2000, the average person in the UK increased use of artificial light sources as much as 4 times, with a parallel increase in lack of sleep.
Artificial light can inhibit the increase in neuron-neuron and dotak sleep hormone melatonin at night which helps to sleep. Since these lights are found, it is as if the brain makes sense of relaxation delay the return until the next day away.
Charles added a result of modern technology, many people still checking email, doing homework or watching television in the evening, all of which it is a source of light at night. In one study, 30 percent of all adults who work in the UK and 44 percent pekeja night reported that they slept less than 6 hours on average per day.
About 50 years ago less than 3 percent of the U.S. adult population was so little. And Charles also said throughout the world, the children slept 1.2 fewer hours in school today than a century ago.
"The technology effectively separates us from the natural 24-hour clock for the development of the body kit and take us longer delay time to sleep. And we use caffeine in the morning because they have to wake up early and hit our sleeping time," concludes Prof. Charles.
Well, start to avoid the artificial light source before bed, then Jagalan sleep patterns and wake up on time to maintain a healthy body and your brain.
