Diabetologia (Sept 8, 2020) – Insomnia with objective short sleep duration has been associated with an increased risk of type 2 diabetes in observational studies [27, 28]. The present MR study found strong and suggestive evidence of a causal association of insomnia and short sleep duration, respectively, with increased risk of type 2 diabetes.
The present study verified several previously reported risk factors and identified novel potential risk factors for type 2 diabetes. Prevention strategies for type 2 diabetes should be considered from multiple perspectives on obesity, mental health, sleep quality, education level, birthweight and smoking.
This was a laborious and apparently objective study.
The discovery of insomnia as a unique risk factor is no surprise, and reinforces the restorative IMPORTANCE of SLEEP.
I was surprised to see docosohexanoic and Eicosapentanoic acids in the risk column and LDL in the good column. However they were studying type 2 diabetes, and not vascular health. I will continue to take my fish oil, and enjoy my HDL, which is in the good column.

You know you need to get enough sleep, but the question remains: How much is enough? Sleep scientist Matt Walker tells us the recommended amount for adults and explains why it’s necessary for your long-term health.

Sometimes I wake up in the morning with a feeling of RELAXED ENERGY. My mind is clear, I have no fatigue, and believe once more that the world is wonderful, and it’s great to be alive.
I St-re-tch, exercise my hands (I have Osteoarthritis, and they are stiff), take out my Nite guard ( I grind my teeth at night and would otherwise wear them away), take my beta blocker eye drops ( to lower my intraocular pressure) and wash down my Eliquis ( an anticoagulant to prevent stroke from my Atrial Fibrillation) with 16 oz. of water, while thinking about all of the delights awaiting me.
Yes, my body was in better shape 60 years ago; but I had much more responsibility then, and much less discretionary time. All things considered, I like to believe that I am happier now.
The KEY is to stay in GOOD HEALTH. GOOD SLEEP is critical, but it cannot be had by willpower alone. As I have discussed previously, you need a bedtime routine, good SLEEP HYGIENE.
You also need a…….. GOOD DIET. with lots of fruits, vegetables and whole grains. Fatty, spicy foods will stay in your stomach and bother you at night, particularly if you eat Late. I like to finish eating by 5 PM. Late dinner is also likely to produce GERD, and maybe Sleep Apnea.
GOOD EXERCISE is also critical. If you are not tired at the end of the day, it is hard to get good sleep. I always seem to sleep better on the day when I walk the hills for an hour, which is 3 days a week. Try not to exercise within 2 hours of bedtime. Assuming that you have a good base of SLEEP, DIET and EXERCISE, there are other mechanisms that can foul things up. INFLAMMATORY conditions often cause fatigue.
The most common inflammatory diseases are OBESITY, METABOLIC SYNDROME and DIABETES. OBESITY is the defining disease of our EXCESSIVE SOCIETY, where there is too much of everything, and excessive consumption is relentlessly advertised everywhere.
External correction is probably a pipe dream, since there is no will even to Tax Sugar-containing Beverages, the “low hanging fruit” of dietary excess. Internal correction is all that is left, and that takes WILL POWER, also in short supply.
INFECTIOUS DISEASES are a subset of inflammatory conditions. COVID 19 is the poster child of infection, and FATIGUE is one of the hallmarks of the disease. Interleukins, like TNF-alpha, IL-1, andIL-6 are some of the defense factors which cause the fatigue. AUTOIMMUNE Diseases like Rheumatoid Arthritis and Lupus are also associated with fatigue-producing interleukins.
Fatigue even has its own flagship disease, CHRONIC FATIGUE SYNDROME. Chronic viral disease has been suspected as the cause of this condition, and inflammatory cytokines may be elevated. This condition, and the similar GULF WAR SYNDROME are still poorly understood. Several CFS patients were sent to me when I was in practice, and I had some success in getting them to exercise regularly, which seemed to help. CANCER is another category of diseases where Fatigue is prominent.
Inflammation plays a role in these diseases, which also drain energy substrates from the Patients body; Cancer cells have a high metabolic requirement. MEDICATIONS, Cancer meds especially, but a variety of other Drugs are associated with FATIGUE. I went through MY MEDICATION LIST. Lo and behold, 3 of them are associated with fatigue.
Finasteride is a relic of my prostate operation, recommended to keep it from growing back. It causes fatigue, probably because of its ANTITESTOSTERONE effect. At least I can still pee, and am not bald. I take METFORMIN because of its fame in prolonging life. Its mechanism is that of interacting with the Sirtuin system, and increasing the inefficiency of mitochondria. Isn’t this surprising?
Like many other things in physiology, you place a stress on the body, and the body responds by improving its performance. If you are fatigued, you exercise. Respecting the body works with drugs as well. If you are drinking a ton of coffee and stop it, after a few weeks you will feel less fatigued.
And when you ARE FATIGUED, you drink a LITTLE coffee, and it wakes you right up. Caffeine works by displacing ADENOSINE, which causes Fatigue as it increases through the morning, peaking at SIESTA (or tea) time,at about 2 PM. OMEPRAZOLE, which I take to prevent HEARTBURN, also is related to fatigue especially if it blocks MAGNESIUM for long enough. DEPRESSION overlaps with fatigue, as does SLEEPINESS, to increase the complexity of the situation.
Many chronic LUNG, KIDNEY and LIVER diseases are associated with fatigue as a secondary concern. STAY HEALTHY!
Coffee has a long and colorful history. Billions of cups are consumed daily, and with such a large and passionate audience, I offer you a taste of the aura which abound on the subject of this popular drink.
The African story of happy animals galloping around at night after eating some red berries from bushes more than a thousand years is probably a myth. It wasn’t until 15th C. Yemen that the documented history of coffee begins.
The substance that was initially ingested wasn’t even a beverage, but was more like an evil-tasting paste. The reason that it endured was undoubtedly it’s stimulating quality.
The Muslim world proscribed alcoholic beverages, but coffee enabled the faithful to pray all night, and was welcome. The Time taken to bring the berries to market often resulted in spoilage. The cargo had to travel from Ethiopia to the port of MOCHA in Yemen, and by a long Voyage to middle eastern destinations.
With the blessings of the Ottoman Empire, however, roasting of the coffee berry was developed, and the resulting coffee bean was more stable. The market heated up, and plantings of C. arabica spread to JAVA and beyond. Eventually, the pleasures of Coffee reached Vienna,and by 1652, the first House dedicated to coffee drinking opened in London.
Coffee Houses spread, and soon catered to special groups like writers, Philosophers and Merchants. Lloyds of London started as a discussion group of traders who were privy to Embarking ships’ Bills of Lading, and enjoyed an economic advantage. Soon the different coffee houses excluded the general public.
The Tastes of the British drinking public was malleable, however. Just as disputes with France caused a switch from wine to gin, the East India Companies plethora of TEA eventually resulted in substantial displacement of coffee drinking by the english tea ritual.
The reverse happened in Revolutionary America. Beginning with the Boston Tea Party, coffee drinking became more popular. By the time of the Civil war, it was unthinkable for Confederate soldiers not to have their ration of coffee.
America is presently the country with the largest coffee consumption. However, the per Capita coffee consumption is higher in a dozen other countries, especially in Scandinavia. Those long, dark winters, with associated increase in seasonal depression meshes well with the STIMULATING VIRTUES OF COFFEE.
Yes, Coffee is stimulating, and its effect can, and often does become ADDICTIVE, as I discovered when I started my Medical Practice. I was drinking three cups of coffee a day and still was tired all of the time, since I was often up at night taking care of my asthmatic patients; I finally decided to quit drinking coffee, and after a full three weeks, started feeling better.
For me, coffee was NOT A SUBSTITUTE FOR SLEEP. I know of at least one Red Bull accolite that disagrees with me, and the NEJM article on the benefits of coffee would seem to support drinking more than one cup of coffee a day.
I currently take about 50 mg. Of caffeine by tablet about every 3-4 days when I am tired in the early afternoon, before 2:30 PM, so as to clear the drug from my system by bedtime. If I use it more frequently, I do not enjoy the same pleasant alertness that less frequent use affords.
I currently drink a cup of green tea in the morning, which I believe delivers about 20 mg. Of caffeine and some other health benefits as well. Caffeine makes you more alert by competitively blocking the sedative action of Adenosine, which gradually accumulates in parallel with ATP depletion during the course of energy expenditure in the activities of the waking day.
Chemically, caffeine is trimethylxanthine, and is a cousin to the drug theophylline, which was the mainstay of asthma therapy for the first decade or so of my allergy practice. Before theophylline therapy was standardized, a strong jolt of coffee was often used for severe asthma.
Coffee apparently shares with Theophylline the inhibition of Phosphodiesterase, causing the heart to speed up, and lung airways to open. So enjoy your coffee, especially after reading about its health benefits in the recently posted NEJM article.
But be careful about drinking too much. There is rarely such a thing as a ’free lunch” in the worlds of economics and drugs. YES, CAFFEINE IS A DRUG, and the intoxicating aroma notwithstanding, please respect it as such.
Osteoarthritis (OA) was considered a Degenerative disease when I went to Med School in the late 50s. I am more interested in OA since I have developed it myself.
There is a 40-60% hereditary component. My father’s mother had arthritis badly in her hands, as did my mother’s mother, and so on. A lot of genome-correlation work has shown many different genes involved,
But without a single big contributor, OA appears to be “multifactorial”, similar to a lot of common diseases like Diabetes l. Trauma can be a factor. Old sports injuries, like an ACL tear, that you thought a thing of the past, may come back to haunt you in later years.
INFLAMMATION, the most popular explanatory cause of the decade, may be operating in OA. For instance, you can imagine that OBESITY would contribute to hip and knee OA simply through the traumatic force of gravity. But obesity is also a disease of Inflammation, and increases IL-6 and other cytokines as well.
My own OA involves the classic distal 2 interphalangeal joints (go to the wikipedia manekin for a color-representation of OA classic locations). The base of my thumb, neck and back are also a problem.
Strangely, but wonderfully, my “wheels”, the Hips and Knees, are spared. I have exercised a lot in my life. Clearly, you can’t “wear out” your joints with ordinary exercise.
Our joints have evolved to allow us to move. Since bone has a lot of pain fibres, it would be painful to move the joints, directly bone-on-bone. So we have cartilage on the ends of the bones and discs between the vertebrae. The cartilage is slick to reduce friction.
Cartilage has no blood to supply it with nutrients. Instead, it relies on the joint (synovial) fluid. The cartilage is like a sponge. Walking alternately compresses and relaxes the spongy cartilage, increasing the synovial fluid circulation, thus improving the nutrition of the cartilage. If the Cartilage disappears, there is pain.
I am not a fan of pain medication. My belief was strengthened by the side effects of the study of a medication designed to genetically block pain transmission by injection into the painful joints. The side effect was virtual dissolution of the joints in a fraction of those treated. I felt more comfortable with my pain after reading the article.
Although Acetaminophen helps a little, NSAIDs usually work better, perhaps because of their anti-inflammatory action.
If, like me, you have stomach issues, there are the COX-2 inhibitors like Celebrex. The one dose I recently took was almost magical in its effects. Maybe if you don’t use pain Meds much, they work better.
I do take Glucosamine-Chondroitin, thinking that providing building blocks for cartilage couldn’t hurt. Along this line I also EAT CARTILAGE whenever I eat Chicken or ribs, being careful not to damage my teeth in the act of of exercising my jaws.
I also take Curcumin, hoping to relieve some pain, in spite of the fact that it is poorly absorbed (some brave souls take it by injection). I don’t know if any of this helps, How can you know in such a variable disorder, in the absence of controlled studies.
And pain has no OBJECTIVE markers, and is notoriously hard to study. We literally know more about the surface of mars than we know about Pain.
SLEEP, DIET, and EXERCISE, by minimizing OA factors kike OBESITY and INFLAMMATION are the best bet for preventing and treating OA at present.
I recently posted a discussion on osteoporosis that was based on a MNEMONIC, using the word itself as the basis of exploring the Risk factors Evidence that you have Osteoporosis is hidden, and are discovered by Dexascan, or when you suddenly have a major fracture.
DEPRESSION is common, but sneaks up on you. It may be a job to discover that you have it, to DIAGNOSE it, so that you can be treated. The diagnosis has about 10 markers that can be formulated into a mnemonic, so that you can remember what they are. My favorite is by Paul Blenkiron, writing in the BMJ:
These 10 symptoms are described in the 10th edition of “the international classification of Diseases. The problem with some mnemonics is to remember the mnemonic itself.
Not here. Interestingly, The 4 PILLARS OF HEALTH are each represented in this list. 3 of them are valid TREATMENTS for DEPRESSION, as you will see in the following articles. When I looked up intellectual stimulation as a treatment for Depression, all i found was electrical or magnetic deep brain stimulation.
I can’t help but believe that INTELLECTUAL STIMULATION itself would at least help ward off much Anxiety and Depression. SLEEP has an interesting relationship to depression. Lack of sleep can be a CAUSE of Depression.
Recently, deprivation of sleep has been used to TREAT episodes of severe depression. Obviously there is a lot we don’t know. Another puzzlement is the several week delay in the effect of SSRI medications. I acknowledge that throughout history many great intellects have manic-depression, which may be key to their productivity.
Depression itself is credited with deep understanding. The “black Dog” of depression is best avoided, however. A HEALTHY LIFE STYLE SHOULD HELP WARD OFF DEPRESSION.
“We’ve discovered that fragmented sleep is associated with a unique pathway — chronic circulating inflammation throughout the blood stream — which, in turn, is linked to higher amounts of plaques in coronary arteries,” said study senior author Matthew Walker, a UC Berkeley professor of psychology and neuroscience.
Disrupted nightly sleep and clogged arteries tend to sneak up on us as we age. And while both disorders may seem unrelated, a new UC Berkeley study helps explain why they are, in fact, pathologically intertwined.
Some tips to improve sleep quality
Maintain a regular sleep routine, going to bed and waking up at the same time each day.
As part of a nightly wind-down routine, avoid viewing computer, smartphone and TV screens in the last hour before bedtime, and keep phones and other digital devices out of the bedroom.
Engage in some form of physical exercise during the day.
Get exposure to natural daylight, especially in the first half of the day.
Avoid stimulants, like caffeine, and sedatives, like alcohol, later in the day.
UC Berkeley sleep scientists have begun to reveal what it is about fragmented nightly sleep that leads to the fatty arterial plaque buildup known as atherosclerosis that can result in fatal heart disease.
“How much sleep do we need”, and “Sleep Hygine” were past topics on this site, and my own sleep fragmentation was mentioned. This study correlates sleep fragmentation in the elderly with increased blood vessel disease compared to elderly people who have no interruptions in their sleep.
The elderly have several obstacles to a good, full night’s sleep, although a fair number of my friends claim the blessings of sleeping soundly. As we get older, we lose the deepest sleep we enjoyed as children, and there is some loss of REM sleep as well. The elderly sleep more lightly.
Diseases begin to accumulate as we get older, and These DISORDERS and their TREATMENT can disrupt sleep. I mentioned My BPH with it’s blockage of flow, leading to incomplete emptying of my bladder. This led to FREQUENT URINATION and frequent arousal at night.
With aging, the tissues in the throat become more flabby, and if you SLEEP on your BACK, your inhalation may be blocked. This may result in OBSTRUCTIVE SLEEP APNEA, where your breathing and sleep are interrupted repeatedly. The associated SNORING may interrupt the sleep of your partner, or even the sleep of those in the next room.
GERD, where you choke on regurgitated stomach contents, is more common in the elderly.
Chronic Heart, lung and Kidney disease can interfere with sleep. SLEEP DEPRIVATION leads to a variety of problems, such as the inflammation and Arterial blockage highlighted in the above article.
Sleep is intimately connected with DIET and EXERCISE. As one of the PILLARS of HEALTH, It s well worth discussing with your Doctor and following her instructions.
“We took an unbiased approach and searched throughout the body for indicators of damage from sleep deprivation. We were surprised to find it was the gut that plays a key role in causing death,” said senior study author Dragana Rogulja, assistant professor of neurobiology in the Blavatnik Institute at HMS.
The first signs of insufficient sleep are universally familiar. There’s tiredness and fatigue, difficulty concentrating, perhaps irritability or even tired giggles. Far fewer people have experienced the effects of prolonged sleep deprivation, including disorientation, paranoia, and hallucinations.
Total, prolonged sleep deprivation, however, can be fatal. While it has been reported in humans only anecdotally, a widely cited study in rats conducted by Chicago-based researchers in 1989 showed that a total lack of sleep inevitably leads to death. Yet, despite decades of study, a central question has remained unsolved: Why do animals die when they don’t sleep?
Now, Harvard Medical School (HMS) neuroscientists have identified an unexpected, causal link between sleep deprivation and premature death.
“The biggest problem has been staying asleep,” says Philip Muskin, a professor of psychiatry at Columbia University Medical Center in New York. “People aren’t exercising, their days have no structure at all.”
Preliminary results from a survey taken by around 1,600 people from 60 countries show that 46% reported poor sleep during the pandemic, while only 25% said they had slept poorly before it, according to Melinda Jackson, a senior lecturer at the Turner Institute for Brain and Mental Health at Monash University in Melbourne, who studies how stressful events affect people’s sleep. Forty percent also reported increased alcohol consumption.
The key is to prevent the sleep problem from becoming chronic, she says. It is important to avoid associating your bed or bedroom with a place where you are awake. Experts recommend that if you can’t fall asleep, or wake up in the middle of the night and are unable to go back to sleep after 20 minutes, get out of bed and do something relaxing.
