Warned doctor Charles Kizlr, the head of sleep medicine at the hospital, "Brigham & and" America, that the consideration of computer screens, smart phones and television,
During
the evening causes lack of sleep, which increases the risk of several
health problems, including: obesity, depression, heart disease, and
stroke.According
to an article Kizlr in the journal "Nature" scientific, exposure to
light supply in times of the night, which is supposed to be the time of
normal sleep, is the most important reason in a lack of sleep
disturbance, although there are other factors, the most recent system of
contemporary life that moves throughout the twenty-four hours a day, seven days a week, such as waking up early to work and study, and excessive intake of caffeine, and long trips.He says: "As a result, many people continue to read e-mail, or doing homework or watching TV in the middle of the night."And
reduces exposure to artificial light from the comfort of your body
during the night Ptthbyth neuronal activity responsible for sleeping
with the activation of cells responsible for alertness, next to impede
the secretion of the hormone sleep known as "melatonin" as affect the
light-sensitive cells in the eye, and lead these factors together to the
disruption of time biological or vital body, which played organized bedtimes and wake up.According
Kizlr that technology cause our dimensions of the pattern today natural
that suits our bodies, believed to be the spread of artificial lighting
and the continuous increase in consumption has led to the prevalence of
lack of sleep; terms linked to lower the cost of providing lighting to
increase per capita consumption to her, Starting from the early fifties
of the twentieth century and until the end the
cost of producing light fell six times in the United Kingdom, and in
return has doubled per capita consumption of light at a rate four times.Which
is consistent with the opinion of Dirk - Jean DIGIC, Director, Center
for Sleep Research at the University of "confidential" British, who
believes the impact of exposure to artificial light in the evenings to
reduce the tendency of drowsiness; became the actions of people is the
main factor in determining the sleep time, unlike the past, when Earth's rotation on its axis, which controls the day and night, is the first set.Some
studies suggest a decline in the number of hours of sleep for many
people in recent years, according to a poll published last year, the
average hours of sleep 30% of employees and 44% of the workers in the
periods evening in the United States less than six hours a night, which
is different much about the situation fifty years ago; as it was only about 3% of the U.S. population slept little. As reported by 5% of staff British Bnomanm the less than five hours a night.And
globally sleeping children at the present time during the school days
less than it was the situation a hundred years ago an average of 1.2
hours.The
Kizlr believes that a lack of sleep in children are motivated to wake
up and not more than feeling sleepy, also cause poor focus. And
is likely to be lack of sleep among the leading causes of what is known
as the syndrome "attention deficit disorder and hyperactivity," which
suffered 19 percent of American boys at the secondary level.It
is expected Kizlr high number of people who suffer from lack of sleep
in the future due to increased exposure to light, which accounts alone,
19% of the budgets allocated for electricity generation around the
world, the trend of many countries to replace the bulbs bilateral
light-emitting "Walid", which are used widely in Many of the TV screens and computers, smart phones, replacing traditional lamps with incandescent lighting.
