Sleeping Your Way to Better Health

 

 4 good reasons to get a good night’s sleep

 

 Snooze News from SleepSavvy Magazine:
New Scientific research continues to unmask the effects of chronic sleeplessness, and the results are enough to keep you up at night!  Here are four of the most devastating effects, courtesy of the American Heart Association:

 

1) Sleep Loss can lead to diabetes.  A  recent study shows that “people who sleep less than six hours a night appear to have a higher risk of developing impaired fasting glucose — a condition that can precede type 2 diabetes.”

2) Sleep Loss can reaise your blood pressure. Another recent study found that a lost hour of sleep — one hour less than the recommended eight — increased the odds of developing high blood pressure and average of 37% over five years; skipping two hours raised the blood pressure risk 86%.  this condition can lead to heart attack, stroke or kidney failure.

3) Sleep loss can make you fat.  Several recent studies have confirmed that there is a link between lost sleep and weight gain.  In one study, participants who slept six hours per night were 27% more likely to become obese than those sleeping seven to nine hours; people getting five hours of sleep per night were 73% more likely to become obese; and those with only two to four hours of sleep per night were 67% more likely to become obese.

4) Sleep loss can make you vulnerable to cancer.  Yet another recent study showed that even when people take preventative actions that have been proven to lower cancer risks (such as exercising and eating right), inadequate sleep seems to counteract those benefits.
More research is underway on these and other health risks associated with cheating on sleep.  Meanwhile, you might want to alert your family, friends and neighbors:  Don’t shirk on the shut-eye.

If you sleep on a FloBed Latex Mattress , you’ll:

*Feel Better

*Live Longer

*Be Healthier

Insufficient sleep will slow down your metabolism.

In addition, not getting enough sleep will cause excessive eating and weight gain. A lack of sleep will increase ghrelin (hunger hormone) levels and decreases levels of leptin (the hormone that signals fullness). “Research has showed that when study participants didn’t get enough sleep for five days, they consumed more carbohydrates and gained nearly 2 pounds in that time.” USA Today

So stop sabotaging your healthy diet and rigid workout routine. Make sure you get some sleep so you can reach your goals. Think about a latex mattress if your not comfortable in bed.

Sleep is Important

We know that sleep is important, it is something that we were taught at a young age.  But have you ever asked why is sleep so important? Here are some  critical things that happen while you are asleep:

  • Brain- the cerebral spinal fluid whisks away the waste that the brain cells create. This allows you to wake up the next day with a clean slate.
  • Heart- it gets a break while you are sleeping. During non-REM sleep your heart gets to rest, which reduces your heart rate and blood pressure.
  • Muscles- growth hormones rebuild your muscles and joints. The more sleep you get the easier it is for your body to repair it’s self.

Make sure that you prioritize sleep so that you can think straight, give your heart a break, and grow nice and tall.

Did you know a good night’s sleep can help avoid stomach fat?

I just read that two studies published in the journal Sleep build a strong case for the relationship between too much body fat and too little sleep. Researchers found that women who slept less than 5 hours a night showed a 32% weight gain in abdominal fat over a five year period compared to a 13% gain among those who slept 6 or 7 hours.
How can that be?  Well, according to Jenny Theorell-Haglow, one of the sleep study authors, it’s because, “Short sleep duration, short dream sleep and short deep sleep disturb the production of cortisol and growth hormones in a way that can contribute to driving body weight upwards.”
So remember, spending at least 6 or 7 hours a day on a FloBed sleep system is good for your waistline.

Sleep ‘cleans’ the brain of toxins

By James Gallagher Health and science reporter, BBC News

The brain uses sleep to wash away the waste toxins built up during a hard day’s thinking, researchers have shown.

The US team believe the “waste removal system” is one of the fundamental reasons for sleep.

Their study, in the journal Science, showed brain cells shrink during sleep to open up the gaps between neurons and allow fluid to wash the brain clean.

They also suggest that failing to clear away some toxic proteins may play a role in brain disorders.

One big question for sleep researchers is why do animals sleep at all when it leaves them vulnerable to predators?

It has been shown to have a big role in the fixing of memories in the brain and learning, but a team at the University of Rochester Medical Centre believe that “housework” may be one of the primary reasons for sleep.

“The brain only has limited energy at its disposal and it appears that it must choose between two different functional states – awake and aware or asleep and cleaning up,” said researcher Dr Maiken Nedergaard.

“You can think of it like having a house party. You can either entertain the guests or clean up the house, but you can’t really do both at the same time.”Plumbing

Their findings build on last year’s discovery of the brain’s own network of plumbing pipes – known as the glymphatic system – which carry waste material out of the brain.

Scientists, who imaged the brains of mice, showed that the glymphatic system became 10-times more active when the mice were asleep.

Cells in the brain, probably the glial cells which keep nerve cells alive, shrink during sleep. This increases the size of the interstitial space, the gaps between brain tissue, allowing more fluid to be pumped in and wash the toxins away.

Dr Nedergaard said this was a “vital” function for staying alive, but did not appear to be possible while the mind was awake.

She told the BBC: “This is purely speculation, but it looks like the brain is losing a lot of energy when pumping water across the brain and that is probably incompatible with processing information.”

She added that the true significance of the findings would be known only after human studies, but doing similar experiments in an MRI machine would be relatively easy.

Commenting on the research Dr Neil Stanley, an independent sleep expert, said: “This is a very interesting study that shows sleep is essential downtime to do some housekeeping to flush out neurotoxins.

“There is good data on memory and learning, the psychological reason for sleep. But this is the actual physical and chemical reason for sleep, something is happening which is important.”

Dr Raphaelle Winsky-Sommerer, a lecturer in sleep at Surrey University, said: “It’s not surprising, our whole physiology is changing during sleep.

“The novelty is the role of the interstitial space, but I think it’s an added piece of the puzzle not the whole mechanism.

“The significance is that, yet again, it shows sleep may contribute to the restoration of brain cell function and may have protective effects.”

Many conditions which lead to the loss of brain cells such as Alzheimer’s or Parkinson’s disease are characterized by the build-up of damaged proteins in the brain.

The researchers suggest that problems with the brain’s cleaning mechanism may contribute to such diseases, but caution more research is needed.

The charity Alzheimer’s Research UK said more research would be needed to see whether damage to the brain’s waste clearance system could lead to diseases like dementia, but the findings offered a “potential new avenue for investigation”.
