How long you sleep may be in your genes

The amount of time people spend sleeping is linked with two regions of their DNA, a new study suggests

“Sleep patterns are influenced by genetic differences,” said study author Dr. Daniel Gottlieb, the director of the Sleep Disorders Center at VA Boston Healthcare System. “This study is one of the first to begin identifying these genetic differences, and will hopefully help us better understand the causes of sleep disorders and their relation to other important conditions, such as diabetes and psychiatric disorders.”

If you’re a worrier, going to bed earlier could help

Those who feel stressed and anxious all the time might want to try one simple remedy before others: Go to bed earlier. It’s not just a matter of getting a good night’s sleep, however.

Researchers at Binghamton University say that when you go to sleep matters when it comes to fending off “repetitive negative thinking,” according to a post at Eureka Alert.

“Making sure that sleep is obtained during the right time of day may be an inexpensive and easily disseminable intervention for individuals who are bothered by intrusive thoughts,” says one of the researchers for the study published in Cognitive Therapy and Research.

Study: Sleeping After Learning Improves Memory

Sleeping directly after learning new information may improve your memory, according to a new study.

Brigham and Women’s Hospital researchers closely evaluated 14 participants and found that they were substantially better at remembering information like faces and names of people if they were able to get up to eight hours of sleep afterward.

“We know that many different kinds of memories are improved with sleep. While a couple of studies have looked at how naps might affect our ability to learn new faces and names, no previous studies have looked at the impact of a full night of sleep in between learning and being tested,” corresponding author Dr. Jeanne F. Duffy said in a public release. “We found that when participants were given the opportunity to have a full night’s sleep, their ability to correctly identify the name associated with a face – and their confidence in their answers – significantly improved.”

Overnight shift, jet lag cause ‘chaos’ in body

Working overnight causes “chaos” in the body and could lead to long-term damage, BBC News reported.

In a study published in Proceedings of the National Academy of Sciences, researchers found that subjects who went from a normal sleep pattern to that of a night-shift worker experienced changes at the molecular level.

Power napping really IS good for you: A 30-minute snooze can repair the damage caused by a lack of sleep

Indulging in a power nap can repair the damage caused by a lack of sleep, new research today claims.

Having a 30-minute snooze can help relieve stress and bolster the immune systems by restoring hormones and proteins to normal levels.

‘This is the first study that found napping could restore biomarkers of neuroendocrine and immune health to normal levels.

‘Napping may offer a way to counter the damaging effects of sleep restriction by helping the immune and neuroendocrine systems to recover.


Seen At 11: Daylight Saving Time Can Be A Danger To Your Health

“Our body has a natural circadian rhythm which is almost an internal clock that regulates our 24-hour cycle. It regulates our sleep-wake cycle and that can be disturbed fairly easily,” said neuro-psychiatrist Dr. Julia Samton.  According to Samton, even moving the clocks just one hour may mean disrupted sleep patterns, and more, for some people.


How a bad night’s sleep could age your brain by five years: Poor quality slumber causes loss of memory and concentration

Sleeping badly could age you as much as five years, a study has revealed.

Just three or four years of broken sleep patterns are linked to a loss of memory and concentration, American researchers found.

They say that poor quality sleep is increases the risk of of having impaired mental faculties by up to 50 per cent – equivalent to a five year increase in age.


Three grams glycine improves your sleep

If you take 3 grams of glycine an hour before going to bed, you’ll sleep better. Researchers at the Japanese ingredients manufacturers Ajinomoto discovered this when they did a small study using nineteen female employees at the company as test subjects.


Study ties troubled sleep to lower brain volume

People who have trouble sleeping tend to have less volume in certain regions of the brain than those without sleep problems, a new study of Persian Gulf War veterans suggests.

“People discount the importance of sleep. So many things seem so much more important than a few extra hours of sleep a night,” lead author Linda L. Chao told Reuters Health.

“The study suggests we shouldn’t discount sleep importance,” she said.

Naps linked with higher risk of death

Middle-age and older adults who take daytime naps may be at increased risk of dying, a new study from England suggests.

In the study, people ages 40 to 79 who napped daily, for less than an hour, were 14 percent more likely to die over a 13-year period, compared to those who did not nap. Longer naps were linked with a higher risk: people whose daily naps lasted an hour or more were 32 percent more likely to die over the study period.
