The Steep Cost of Sleep Deprivation

Via Mercola

Story at-a-glance

  • Sleep deprivation has the same effect on your immune system as physical stress or illness and increases your risk of numerous chronic diseases, including obesity, insulin resistance, diabetes and Alzheimer’s
  • Research confirms that sleep is an important factor in children’s risk for diabetes, and that children need far more sleep than adults. Even at eight hours a night, children were at increased risk of obesity and insulin resistance when compared to those who slept up to 12 hours or more
  • Babies have improved recall after napping, suggesting sleep plays an important role in memory solidification. Amyloid plaques, common in Alzheimer’s disease, also build up more quickly when you’re sleep-deprived

What I have learned since this article was initially posted is that if you supply your body, and your brain specifically, with enough near infrared light, the average person will need 48 minutes less of sleep per night. I currently sleep less than six hours a night as per Oura ring sleep tracking data. I rarely use an alarm and have more than enough energy throughout the day. I will be posting more details on near IR light later this year.

In addition to helping blood pressure and cardiovascular health, deep sleep may play a role in preventing Alzheimer’s disease

A new study in the peer-reviewed journal Science says cerebrospinal fluid during non–rapid eye movement sleep clears metabolic waste products from the brain

Deep sleep may be critical for your heart — but it may also help clear the brain of toxins that play a role in Alzheimher’s disease. Sleep is essential for both cognition and maintenance of healthy brain function, and slow waves in neural activity contribute to memory consolidation, a study published Thursday in the peer-reviewed journal Science concluded. Cerebrospinal fluid during non–rapid eye movement sleep also clears metabolic waste products from the brain.

Catastrophic Consequences of Chronic Sleep Deprivation

Guest Post by Dr. Mercola

  • About 1 in 3 Americans gets less than seven hours of sleep a night, and more than 83 million adults in the U.S. are sleep-deprived
  • Some of your “enemies of sleep” may include alcohol and caffeine, anxiety and depression, artificial lighting, long work hours, loneliness and overcommitment
  • Consistent lack of high-quality sleep wreaks havoc on your body’s two hunger-regulating hormones: ghrelin, also known as your “hunger hormone,” and leptin, referred to as your “obesity hormone”
  • Lack of sleep significantly raises your risk of developing Alzheimer’s disease, mainly because amyloid-beta deposits that would normally be cleaned out of your brain nightly during deep sleep accumulate and kill off surrounding cells
  • Poor sleep makes you two to three times more likely to develop a chronic pain condition. It also puts you at risk for other health problems such as higher cortisol levels, increased inflammation and reduced immune function

This expert has a dire warning about not getting enough sleep

Sleep expert Matthew Walker is not a fan of the expression “you can sleep when you’re dead.”

In fact, he calls it “mortally unwise advice.”

“Sleep is Mother Nature’s best effort yet to counter death,” Walker says.

He would know. Walker, who is director of the University of California, Berkeley’s Center for Human Sleep Science, has been studying sleep for more than 20 years and is the author of a new book, “Why We Sleep: Unlocking the Power of Sleep and Dreams.”

Walker’s work centers around a major and often overlooked problem: many Americans are sleep-deprived. One in three U.S. adults report they usually get less than the recommended seven hours, according to the Centers for Disease Control and Prevention.

President Donald Trump doesn’t get much more than 40 winks.

“I am working long hours, long hours, and right up till 12 o’clock or 1 o’clock,” Trump told “The O’Reilly Factor” on Fox News Tuesday night. He wakes up at 5 a.m. and is known to send tweets at 3 a.m. In his defense, Trump, 70, also told host Bill O’Reilly that he multi-tasks. “While I eat, I read the papers. I see what’s going on television.” (Fox News is owned by News Corp., the parent company of Dow Jones, which also owns MarketWatch.) The late British Prime Minister Margaret Thatcher famously claimed to get four hours per night, bolstering her image as “The Iron Lady.”

Are you getting enough sleep every night? According to a new study from Rand Europe, sleep deprivation is a serious and costly problem for the globe’s major economies. In the United States, 1.2 million working days are lost every year due to insufficient sleep, costing a whopping $411 billion. That equates to 2.28 percent of the country’s GDP. Japan is also suffering the effects of sleep deprivation, losing 600,000 days and $138.6 billion annually.
