Why sleep is essential for your memory

Friday, April 11th, 2014

pic_01_240x240_apr11Researchers have claimed that infants who nap are better able to apply lessons learned to new skills, while preschoolers are better able to retain learned knowledge after napping.

Rebecca Gomez of the University of Arizona said that sleep plays a crucial role in learning from early in development.

A growing body of research shows how memories become reactivated during sleep, and new work is shedding light on exactly when and how memories get stored and reactivated.

In Gomez’s new work, she and he team are examining how young children can recognize instances similar, but not identical, to something they have learned and apply it to a new situation – so-called generalization. Examples in language include the ability to recognize the letter “A” in different types of font, understanding a word regardless of who is speaking it, or recognizing a grammatical pattern in a sentence never before heard.

Omega-3 rich diet gives better sleep: Study

Friday, March 7th, 2014

Heart-healthy-foods_240x240A new study has revealed that higher levels of omega-3 DHA in diet would give better sleep.

The randomized placebo-controlled study by the University of Oxford found that children on a course of daily supplements of omega-3 had nearly one hour more sleep and seven fewer waking episodes per night, as compared with the children taking the corn or soybean placebo.

According to the study, it found that there is possible links between sleep and fatty acid status in healthy children, and that higher blood levels of the long-chain omega-3 DHA are significantly associated with better sleep, including less bedtime resistance, parasomnias and total sleep disturbance.

Build a strong immune system this winter

Monday, January 6th, 2014

Build a strong immune system this winterWith fall and winter comes flu. The cool winter wind brings with it a swarm of winter diseases.

Inside our body there is an amazing protection mechanism called the immune system and the main job of this system is to guard you against millions of bacteria, microbes, viruses, toxins and parasites that would love to attack your body. Our immune system is directly affected by what we eat, drink and breathe. The poorer the diet, the greater will be the amount of toxins that will accumulate in our body, making us more susceptible to infections, viruses and cancer. Our body is designed to process, metabolize and clear toxins naturally. However, we live in a world where the amount of toxins we take in daily far exceeds permissible levels.

Study reveals worst time to consume coffee

Thursday, December 26th, 2013

A new study has revealed that the worst time to consume caffeine in the day is six hours before bedtime as it can have significant, disruptive effects on sleep.

The study led by Christopher Drake, PhD, investigator at the Henry Ford Sleep Disorders and Research Center, showed that about 2-3 cups of coffee taken at bedtime, three and even six hours prior to bedtime significantly disrupts sleep.

Even when caffeine was consumed six hours before going to bed, objectively measured total sleep time was dramatically reduced (more than one hour).

Drake said that drinking a big cup of coffee on the way home from work can lead to negative effects on sleep just as if someone were to consume caffeine closer to bedtime. People tend to be less likely to detect the disruptive effects of caffeine on sleep when taken in the afternoon.

Lack of sleep linked to mental disorders

Friday, July 26th, 2013

Sleepless nights could lead to serious mental health problems like schizophrenia and bipolar disorder, a new research has claimed.

The study, conducted by Oxford University, has found that circuits in the brain are shared by mechanisms that control sleep and mental health, and therefore if your sleep is disrupted, your mental health could be too, the Daily Express reported.

Professor Russell Foster told the publication that the appalling sleep-wake cycle in schizophrenia is independent of medication and social constraints and is something fundamentally wrong with the body clock of patients with the disease.

The research also identified a genetic mutation that triggers schizophrenia-like symptoms in mice, which also appears to disrupt their body clocks.

Top 5 benefits of power naps

Wednesday, June 5th, 2013

An afternoon nap is always frowned upon. We’ve always been told that it makes you hazy, lazy and disoriented. However, research suggests that a quick mid-day nap or ‘power nap’ can make you alert, reduce stress, improve your cognitive functioning, refresh and stimulate you!

What is power napping?

Power nap is a short 20-minute period of sleep, usually during the day. These naps are said to provide energy and boost your right-brain activity.

New diet promises to help lose weight while you sleep

Friday, April 12th, 2013

The latest trend on the scene – the Overnight Diet, is a rapid weight-loss plan that claims you can actually slim down while you sleep.

American obesity doctor Caroline Apovian, of the Boston Medical Center, just penned a new book, ‘The Overnight Diet,’ advising that dieters eat a high-protein diet for six days, followed by one day of a liquid diet.

That followed by lots of sleep (with no exercise necessary) equals a slimmer you, up to two pounds per night and nine pounds in one week — at least that’s the promise, the New York Daily News reported.

While mounting research suggests that more sleep can help you lose weight, skeptics say the diet is all a little too good to be true.

“In order to lose two pounds of body fat overnight you’d have to burn up about six or seven thousand calories and there’s just no way to do that by sleeping,” Keith Ayoob, director of the nutrition clinic at the college’s Rose F. Kennedy Center, told ABC News.

Lack of sleep makes women grumpier next morning

Monday, March 11th, 2013

A new Duke University survey has found that women wake up far more grumpier than their male counterparts.

In fact, the research stated that females need far more sleep than men and they suffer more mentally and physically if forced to go without it, CBS News reported.

Lack of sleep appears to put them at higher risk of heart disease, depression and psychological problem, but sleep seems to have less effect on men”s health.

The research found that men with sleeping problems showed no increased risk of the conditions that were affecting the women.

In this particular study, women had more depression, anger, and hostility early in the mornings when they weren”t getting the same amount of sleep than they normally get, said Michael Breus, a clinical psychologist, sleep expert and author of “The Sleep Doctor”s Diet Plan.”

Regular good night’s sleep key to keeping heart healthy

Monday, February 25th, 2013

Not getting enough sleep can have harmful effects on your heart, an expert at the University of Alabama at Birmingham (UAB) has said.

The ideal amount of sleep is between six to eight hours, said cardiologist Alan S. Gertler, M.D., associate professor of medicine in UAB’s Division of Cardiovascular Diseases and part of UAB’s Heart and Vascular Services.

“Deep, high-quality sleep is needed to lower heart rate and blood pressure, which reduce stress on the heart,” Gertler said.

Heart rate and blood pressure also rise and fall during rapid eye movement (REM) in response to dreams. According to the National Institutes of Health, those variable rates also contribute to making the heart healthier.

“Without enough sleep, there is an increase in blood pressure and stress hormones, lower glucose tolerance and weight gain. All of these factors can increase the risk of coronary artery disease,” Gertler said.
