SLEEP DEPT - A GROWING PROBLEM

MILLIONS of people today are in serious “debt.” This debt can be a major factor in wrecking their cars, damaging their careers, and even ruining their marriages. It can adversely affect their health and life span. It is a deficit that contributes to immune suppression, creating susceptibility to various infections. Conditions as different as diabetes, heart disease, and extreme obesity, as well as other health problems, have been linked to it. Yet, most victims are oblivious of this debt.

The culprit is sleep debt, which develops when a person does not get the amount of healthful sleep needed for well-being. This can be caused by voluntary sleep deprivation resulting from a person’s life-style or by involuntary sleep deprivation because of illness.

Medical researchers estimate that earth’s population is now getting, on average, an hour less sleep per night than what is needed. While this may seem slight, a nightly six-billion-hour debt has become the focus of research into both the variety of sleep-related illnesses and their impact on the quality of life.

The medical world once viewed the chronic inability to sleep as just one disorder, commonly called insomnia. However, a commission created by the U.S. Congress recognized 17 distinct sleep disorders. At any rate, insomnia has so many causes that it is often considered to be a symptom of other problems, much as a fever suggests some sort of infection.

Even occasional deprivation of sleep can be disastrous. Consider the case of Tom. Although an experienced truck driver, he plunged his 18-wheel vehicle over an embankment, spilling 100 gallons [400 L] of sulfuric acid onto a major highway. Tom admits: “I fell asleep.” Studies of two U.S. highways estimated that drowsy drivers caused some 50 percent of the fatal crashes.

Consider, too, the occupational dangers of being around a sleepy coworker. Says Australian researcher Ann Williamson: “After 17 to 19 hours without sleep [participants’] performance on some tests was equivalent or worse than that at [a blood-alcohol concentration of] 0.05%.” In other words, subjects functioned as if at or beyond the legal limit in some countries of alcohol permitted in a driver’s bloodstream! With hundreds of thousands of sleep-related auto and job-site accidents happening annually, the worldwide cost to productivity and family is enormous.*

What factors may contribute to sleep debt? One is the social phenomenon often called 24/7—operating 24 hours a day, seven days a week. USA Todaydescribes this as “a cultural earthquake that is changing the way we live,” noting that “a new wave of round-the-clock retailers and services is profiting by mocking the clock.” In many lands people watch all-night television programs and access the Internet when they should be sleeping. Then there is the toll taken by emotional disorders, often involving anxieties heightened by stress and the pace of life. Finally, there are a variety of physical diseases that can contribute to sleep debt.

Many doctors note how difficult it is to get their patients to take sleep debt seriously. One doctor complained that chronic fatigue is even considered “a status symbol” by some. And because their condition often worsens very gradually, victims of sleep deprivation may not recognize that they suffer from a serious sleep disorder. Many reason, ‘I’m just getting old’ or, ‘I can’t cope with life, so I tend to shut down’ or, ‘I’m tired all the time because I can never get the long rest I need.’

Reversing this sleep debt is a complex challenge. But understanding how a healthful sleep cycle works and learning to identify the signs of sleep debt can provide the motivation to change. Recognizing the symptoms of a serious sleep disorder can save lives.

CHEAP IMPORTS, FEWER BURGLARIES

"An influx of cheap electronic goods" might put British burglars out of their jobs, according to a Reuters news report from London, quoting criminology lecturer James Treadwell, of the university of Leicester, England. The low cost of DVD players, for example, means that goods have almost Zero resale value. They are "simply not worth stealing", says Treadwell. Price reductions have not put an end to crime, however. On the contrary, thieves are now targeting more expensive and more marketable items, 'such as mobile phones and iPods, which people carry around with them'. Former burglars are thus turning to other Crimes, such as muggings.

IN WHAT LANGUAGE DO BABIES CRY?

From as early as the second day of life, babies cry to the tune of their mother tongue, according to the researchers from Würzburg University, in Germany. The researchers recorded the cries of 30 French and 30 German newborns, analysing frequency, melodic patterns, and pitch. The cries of French babies often began on a lower pitch and then moved  higher, while those of German babies often higher and then became lower. In both cases, the babies were mimicking melody patterns typical of the languages of their parents. Hence, it is believed that language development starts in the womb and that a baby's language starts with its earliest cries.  Stay tune for the next research article.
