Each night, millions of people struggle with falling or staying asleep, and the chief cause is insomnia.
About one-third of Americans experience insomnia at least occasionally, and for 15-20 percent, the problem can last up to three months. For one in 10 Americans, insomnia is a long-lasting, chronic problem, the American Academy of Sleep Medicine says.
Fortunately, a few simple strategies are all it takes to conquer the problem, for most Americans experts say. Among the most important: Avoiding electronic devices at bedtime, says sleep expert Dr. Ari Shechter, Ph.D.
“Most people use light-emitting electronic devices, such as smartphones and laptops, before bedtime despite the fact that such behaviour is associated with insomnia,” Shechter tells Newsmax Health.
Insomnia, which is the most common sleep disorder in the U.S., can increase the risk of depression, blood pressure, heart disease, diabetes, and Alzheimer’s disease, studies show. It also robs people of their quality of life, causing fatigue, inability to concentrate, poor memory, mood disturbances, low energy, and daytime sleepiness, which can result in increased workplace errors and car accidents.
The problem is also getting worse. Today, Americans average less than seven hours of sleep a night, which is two less than in 1910, the National Institutes of Health says.
There are many causes of insomnia, including stress and poor sleep habits, but our modern lifestyle — particularly the use of electronic devices at night — also is taking a toll.
The LED displays on such devices emit “blue light” waves, says Shechter, associate professor of medical sciences at New York City’s Columbia University Medical Centre.
Although such waves are beneficial during the day — they boost attention, your reaction time, and mood — they are detrimental at bedtime because such light suppresses melatonin.
Melatonin is the body’s natural “sleep hormone,” secreted by a gland in the brain in response to darkness, and helps to regulate our body clock.
“Ninety percent of people use these electronic devices within an hour of going to bed, so I think it would be impossible to get them to give them up,” says Shechter.
Shechter has studied the benefits of wearing amber-tinted glasses, which block out blue light.
His team at Columbia gave 14 people who suffer from insomnia amber-tinted glasses, and compared the duration and quality of their sleep with an equal number of people that wore clear lenses for two hours before bedtime.
Four weeks later, the participants switched glasses and repeated the protocol.
The researchers found that those who wore the amber-tinted glasses got 30 minutes more sleep. They also reported longer, better, and sounder sleep, and, overall, an improvement in their insomnia.
They also had lower blood pressure, according to the study, published in Journal of Psychiatric Research.
LED-lit electronic devices are only one of the causes of insomnia. Here are other ways of dealing with insomnia in general:-
