MUMBAI: An Air India Jaipur-Mumbai flight flew well past its destination with both its pilots fatigued and fast asleep in the cockpit. When the pilots were finally woken up by anxious Mumbai air traffic controllers, the plane was about half way to Goa. ( Watch ) This nap in the sky took place about a fortnight ago on the domestic leg of a Dubai-Jaipur-Mumbai flight — IC 612 — which had about 100 passengers on board. "The plane took off from Dubai at 1.35am IST and then from Jaipur at 7am. After operating an overnight flight, fatigue levels peak, and...

This article goes over sleep physiology, stages of sleep and napping. I was unable to copy and paste a section of the article but the link above should help. The article is an excellent, short summary of the issues.

ScienceDaily (Jun. 11, 2008) — A cognitive behavioral intervention for insomnia delivered via the Internet can significantly improve insomnia in adults, according to a research abstract that will be presented on June 11 at SLEEP 2008, the 22nd Annual Meeting of the Associated Professional Sleep Societies (APSS). The study, authored by Lee Ritterband, PhD, of the University of Virginia, focused on 44 participants (mostly female) with an average age of 45 years. The participants were randomly selected to either the cognitive behavioral intervention for insomnia via the Internet or a wait list control. Measures of sleep, mood, cost, and cognitive...

House prices force Americans to sleep in cars By Catherine Elsworth in Los Angeles Last Updated: 12:58AM BST 22/05/2008 Increasing numbers of women and elderly people are taking advantage of a scheme in one of America's wealthiest cities that enables the homeless to sleep safely in their cars at night. Organisers of the programme say they are seeing ever more unlikely people living out of their cars in the exclusive beachfront city of Santa Barbara, where the average house costs more than $1 million(£500,000). Many hold down part-time jobs while bedding down for the night in their vehicles. Barbara Harvey,...

ST. PETERSBURG, Fla. -- A 3-year-old Florida boy with a rare condition has not slept in three years. Doctors said Rhett Lamb of St. Petersburg apparently has a condition called chiari malformation that puts pressure on his brain. Click here to find out more! Rhett has never taken a nap or gone to sleep at night, forcing his parents to keep watch day and night. "(My husband) has the day shift and I kind of have the afternoon shift," mother Shannon Lamb said. "We share the night shift because no one can sleep in the house when he is up...

ATLANTA - People who sleep fewer than six hours a night — or more than nine — are more likely to be obese, according to a new government study that is one of the largest to show a link between irregular sleep and big bellies. The study also linked light sleepers to higher smoking rates, less physical activity and more alcohol use. The research adds weight to a stream of studies that have found obesity and other health problems in those who don't get proper shuteye, said Dr. Ron Kramer, a Colorado physician and a spokesman for the American Academy...

The scientists used fluorescent proteins--green and red in these images--to determine whether E. coli bacteria were active.Credit: Gefen et al., PNAS 105 (22 April 2008) Most antibiotics kill only microbes that are growing and multiplying, leaving untouched a select few that are hibernating. A new study suggests that a dose of the right nutrients can awaken these bacteria for just long enough to kill them with antibiotics. If the strategy works in humans, it might provide a more effective way to treat persistent diseases such as tuberculosis and urinary-tract infections. During infections, bacteria may slow...

PARIS (AFP) - An extra hour between the sheets at night might be the key to shedding excess weight and fighting obesity, according to recent research. "More sleep could be the ideal way of stabilising weight or slimming," said neuro-scientist Karine Spiegel, of France's INSERM, a public organisation dedicated to biological, medical and public health research. While poor eating habits and lack of exercise clearly play a role in the global rise of obesity, recent data indicates that lack of sleep may also be a factor, and one that is often under-estimated. Around 30 surveys carried out on wide population...

(CBS) Human beings spend on average one third of their lives asleep. We know we need to sleep but most of us have never really given a whole lot of thought to why. Why do we spend seven or eight hours a night immobile and unconscious? What really happens inside our brains and bodies while we're sleeping? We've known the purpose of our other biological drives for hundreds of years: we eat to give our bodies energy, we drink to keep hydrated, we procreate to perpetuate the species - among other things. But what is the biological purpose of sleep?...

Headaches linked to mobile phones By Lewis Carter Last Updated: 1:02am GMT 21/01/2008 Radiation from mobile phones damages sleep and causes headaches, according to a study by telephone makers. People using a handset before going to bed take longer to reach deeper stages of sleep and spend less time in them, researchers found. This gives their bodies less time to repair wear and tear during the day, and gives them headaches. advertisementThe findings are particularly alarming for children and teenagers, most of whom, surveys suggest, use their phones late at night. The young need plenty of sleep and failure to...

Sunday is 'worst for a night's sleep' By Bonnie Malkin Last Updated: 1:02am GMT 21/01/2008 It may explain that Monday morning feeling - research has found that Sunday is the most sleepless night of the week. Nearly 60 per cent of employees have their worst night's sleep of the week on Sundays, a survey claims, with restless nights forcing one in four to call in sick on a Monday. Disrupted sleep has also been blamed for a lack of concentration at work (46 per cent) on Mondays, increased irritability towards bosses (30 per cent) and the odd impromptu nap at...

Note: This commentary was delivered by PFM President Mark Earley. From Starbucks, to Red Bull, to No-Doz, Americans are showing signs of addiction to caffeine. Sixty percent of us drink a cup of coffee a day. On average we will drink 52 gallons of soda this year. And Starbucks—they get a whopping $5.3 billion of our collective dough. Whether we are chemically stimulating because we do not get enough sleep, or whether the caffeine itself is depriving us of precious rest, we are also sleeping less than ever before. Americans get an average of six and a half hours of...

...Research shows that teenagers’ body clocks are set to a schedule that is different from that of younger children or adults. This prevents adolescents from dropping off until around 11 p.m., when they produce the sleep-inducing hormone melatonin, and waking up much before 8 a.m. when their bodies stop producing melatonin. The result is that the first class of the morning is often a waste, with as many as 28 percent of students falling asleep, according to a National Sleep Foundation poll. Some are so sleepy they don’t even show up, contributing to failure and dropout rates. Many of our...

How To Sleep Like a Hunter-GathererNot all people sleep in "giant sleep machines," like we do. What’s really going on inside your head when you sleep, dream, or are wide-awake? In his fascinating new book, The Head Trip: Adventures on the Wheel of Consciousness (Random House, $24.95), science writer Jeff Warren explores some familiar and some less familiar states of consciousness, everything from daydreams to lucid dreams. Warren talked to scientists and Buddhist monks, slept in sleep labs, and spent time in a secluded mountain cabin to experience firsthand various states of consciousness. Along the way, he discovered perception-shifting information...

WESTCHESTER, Ill. – Bad dreams in pre-schoolers are less prevalent than thought. However, when they do exist, nightmares are trait-like in nature and associated with personality characteristics measured as early as five months, according to a study published in the January 1 issue of the journal SLEEP. The study, led by Valérie Simard, under the direction of Tore Nielsen, PhD, of the University of Montreal, sampled 987 children in the Province of Quebec, who were assessed by their parents at the 29-month, 41-month, 50-month, five-year and six-year mark. Parents were asked in a questionnaire about the frequency of their child’s...

I open my eyes with a start, like the murderous freak in the slasher movie the audience thinks is dead but isn't. The clock reads 3:55 A.M. I've awakened within six minutes of this time for the past three nights. I shut my eyes and take a breath, hoping to ease back to sleep. Too late. The anxiety is already gathering momentum, my brain roiling with thoughts that have no business being there in the middle of the night. It's like a Law & Order episode in my head: Opposing sides argue and counterargue, witnesses are badgered, lawyers shout objections....

LONDON - It was once scientific heresy to suggest that smoking contributed to lung cancer. Now, another idea initially dismissed as nutty is gaining acceptance: the graveyard shift might increase your cancer risk. Next month, the International Agency for Research on Cancer, the cancer arm of the World Health Organization, will classify shift work as a "probable" carcinogen. That will put shift work in the same category as cancer-causing agents like anabolic steroids, ultraviolet radiation, and diesel engine exhaust. If the shift work theory proves correct, millions of people worldwide could be affected. Experts estimate that nearly 20 percent of...

American Heart Association meeting report ORLANDO, Nov. 7 — A cholesterol-lowering drug appears to disrupt sleep patterns of some patients, researchers reported at the American Heart Association’s Scientific Sessions 2007. “The findings are significant because sleep problems can affect quality of life and may have adverse health consequences, such as promoting weight gain and insulin resistance,” said Beatrice Golomb, M.D., lead author of the study and an associate professor of medicine and family and preventive medicine at the University of California at San Diego School of Medicine. In the largest study of its kind, researchers compared two types of cholesterol-lowering...

Your dreams miss you. Or so says a television commercial for Rozerem, the sleeping pill. In the commercial, the dreams involve Abraham Lincoln, a beaver and a deep-sea diver. Not the stuff most dreams are made of. But if the unusual pitch makes you want to try Rozerem, consider that it costs about $3.50 a pill; gets you to sleep 7 to 16 minutes faster than a placebo, or fake pill; and increases total sleep time 11 to 19 minutes, according to an analysis last year. If those numbers send you out to buy another brand, consider this, as well:...
