A new study takes a look at the like between morning headaches and obstructive sleep apnea. The study involved 462 people with sleep apnea and a controlled group that included 101 people without sleep apnea.
The results showed that about 34 percent of the sleep apnea group reported having morning headaches. People with moderate to severe sleep apnea were more likely to wake with a headache, as well as women were more commonly to wake with frequent headaches rather than men.
People who reported morning headaches had much lower oxygen saturation levels during sleep, but the study was unable to determine a specific cause of the morning headaches.
The good news!
Treating sleep apnea with CPAP eliminated morning headaches in 90 percent of the participants. Other studies of sleep apnea and morning headaches have reported similar findings. But the exact nature of the relationship remains unclear.
Morning headaches can be considered a “nonspecific symptom” of sleep apnea. Waking with a headache is not a clear indication that you have sleep apnea. But you should talk to your doctor if you have frequent morning headaches. This may be a cause for concern if you have other warning signs of sleep apnea.

Studies show that obstructive sleep apnea (OSA) affects much more than just your sleep. It can even damage your brain.
A recent brain imaging study from France involved 16 adults. Each of them had just been diagnosed with sleep apnea.
In numerous brain regions the study found a loss of “gray matter.” This is brain tissue that contains fibers and nerve cell bodies. There also was a decrease in brain metabolism.
The authors suggest that these changes may explain some of the impairments that often occur in people with sleep apnea. Examples include attention lapses and memory loss. The study was published in March 2009 issue of the Journal of Sleep Research.
The results are similar to those found by a research team from UCLA. Their study was published in Neuroscience Letters in June 2008. They reported that people with sleep apnea have tissue loss in the “mammillary bodies.” These are brain regions that help store memory.
In July 2008 the UCLA team published another brain imaging study in the journal Sleep.It involved 41 people with moderate to severe sleep apnea. It also included 69 control subjects matched by age.
Results show that people with sleep apnea have extensive alterations in “white matter.” This is nerve tissue in the brain. It contains fibers that are insulated with myelin -a white, fatty sheath. The structural changes appear in brain regions that help control mood and memory. These regions also play a role in adjusting your blood pressure. Damage also was found in fiber pathways that connect these brain regions.
What causes the brain damage? The authors suggest that oxygen, blood flow and blood pressure may be involved. Sleep apnea involves breathing pauses that can occur hundreds of times a night of sleep. These pauses can produce drastic changes in oxygen levels.
These breathing pauses also reduce blood flow in the brain. People with sleep apnea also are at risk for high blood pressure. Both of these conditions create a potential for brain tissue damage.
Dr. Ronald Harper of UCLA said that the studies show how important it is for sleep apnea to be treated. CPAP is the most common treatment for sleep apnea. The findings make it all the more imperative that OSA be treated as soon as possible to prevent further injury. The long-term effects of OSA are terribly damaging to memory and thinking processes.
Can treatment reverse the brain damage caused by sleep apnea? The authors are uncertain if the changes are permanent.
But studies show that CPAP does help your heart, it may even save your life.
Insomnia can make you feel like your mind is racing out of control. A revealing new study explains why your brain may be unable to put the brakes on your thoughts. It links the problem to low levels of a brain chemical.
A new study shows that GABA levels are reduced by 30 percent in adults with chronic primary insomnia. The study was published in the Nov. 1 issue of the journal Sleep.
GABA is reduced in the brain of individuals with insomnia, suggesting over activity is present. It was explained that low GABA levels create an imbalance of brain activity. This may lead to an inability to shut down waking signals in the brain.
If your GABA levels are low, then your mind can’t slow down. It may race forward at full speed even when it is time to sleep. An over active mind is a key feature of psychophsicological insomnia. At bedtime you are unable to stop thinking and worrying. Your body may be ready for sleep, but your mind remains alert. This state of “hyperarousal” can make it hard for you to fall asleep.
Most with insomnia have “secondary” insomnia. It occurs along with another medical problem, mental illness or sleep disorder. It also may result from the use of a medication or substance. In contrast primary insomnia is unrelated to another health problem. Estimates that about 25 percent of people with insomnia have primary insomnia. The study only links low GABA levels to long lasting, primary insomnia.
All participants in the study had been suffering from primary insomnia for mor than six months. The average duration of their symptoms was about 10 years. The GABA connection affirms that primary insomnia is a legitimate disorder.
Recognition that insomnia has manifestations in the brain may increase the legitimacy of those who have insomnia and report substantial daytime consequences. It was also explained that insomnia can affect your energy, concentration and mood. It also increases your risk of depression.
One solution for the problem of primary insomnia is the use of hypnotic medication. The short-term use of a sleeping pill can help break the cycle of sleepless nights. The study notes that many of the most effective sleeping pills increase activity at the GABA neurons.
Another treatment option is cognitive behavioral therapy. CBT helps you learn how to correct attitudes and habits that hinder your sleep. Many of these bad habits develop as people try to cope with chronic insomnia.
This is a patient undergoing a diagnostic home sleep study prior to undergoing gastric banding surgery. She has a BMI of 44 kg/m2. She stops breathing up to 80 seconds, 63 times per hour and her blood oxygen levels drop to 51% from wake levels of 95%. She was suffering from excessive daytime tiredness.
Severe obstructive sleep apnoea. This patient stopped breathing 122 times per hour of sleep. His heart stopped beating twice for 10 seconds at a time during an apnoea. This video shows one of those occasions.
How CPAP machines can Help!
Continuous Positive Airway Pressure, a simple machine that can save your life.
When you’re feeling stressed on the job, it can be hard to leave work at the office. Your job may preoccupy your mind as you drive, as you eat, and as you interact with family or friends. But the battle to control your mind can intensify when you try to go to sleep.
Sleep and stress are competitors. When stress continually activating a part of the brain that is otherwised used for sleep, then stress wins the tug-of-war.
According the AASM, job stress can be a cause of adjustment insomnia. This involves disturbed sleep or sleeplessness that may last for a few days or a few weeks. Other symptoms may include anxiety, worry and tension.
A common feature of adjustment insomnia is “ruminative thoughts.” This is when you dwell on the same thoughts, chewing them over and over in your mind. You may lie in bed staring at the ceiling, unable to stop thinking about work. Even when you finally fall asleep, your work may invade your dreams. The Staples National Small-Business Survey polled 302 owners and executives of small businesses, and more than half said they dream about work -or “sleepwork.”
Scientific research confirms that job stress can affect your sleep. In 2005 a study in the journal Sleep involved 8,770 Japanese workers. In both men and women, a high level of stress at work was liked to insomnia.
A 2007 study in the International Journal of Behavioral Medicine linked insomnia to these three types of job stressors:
- High work demand
- Low influence over decisions
- High professional compromise
The type of job stress you experience may affect your sleep in different ways. Another study linked work overload to poor sleep quality. Having role conflicts at work was related to non-restorative sleep and trouble falling asleeo or staying asleep.
According to the National Institute for Occupational Safety and Health, sleep disturbances are one early warning sign of job stress. Others may include:
- Difficulty concentrating
- Short temper
- Upset stomach
- Job dissatisfaction
- Low morale
Job stress may be unavoidable. But sleep specialists say you can take steps to improve your sleep even when you are stressed. Establishing a pattern of relaxing behaviors close to bedtime and limiting work to the early evening may help to reduce stress.
Here are jus a few more tips to help you be less restless with work worries:
- Remain active
Try to get some exervise every day. Both your mind and body will be more relaxed when its bedtime.
- Express yourself
Take some time to slow down before going to bed. Get away from the computer, turn off the TV and the cell phone, and relax quietly for 15 to 30 minutes. Take a warm bath, enjoy a light snack or listen to some soft music.
- Avoid “bedwork”
Never bring any work to bed with you; your bed should be refuge from your job. Also avoid doing other activities in bed such as reading, watching TV or talking on the phone. Only use your bed for sleep.
- Get out of bed
If you have trouble falling asleep, get out of bed and do something relaxing until you feel sleep agian. Tossing and turning will only increase your frustrations.
- See a specialist
Some doctors are specialists in behavioral sleep medicine. They can teach you how to relax at bedtime so you can fall asleep more easily.
Current economic conditions in the U.S. are forcing many consumers to cut back on health care expenses. Yet sleep experts advise that the cost of a sleep study is a sound investment for millions of people who suffer from a sleep disorder.
The Centers for Disease Control and Prevention reports that about 15 million adults in the U.S. did not receive needed medical care in 2005 because they could not afford it. In July, the National Association of Insurance Commissioners conduted a national survey. Results show that 22 percent of people have reduced the number of times they visit the doctor because to current economic conditions.
In such a challenging economy, should your sleep needs be a priority?
Sleep is one of the cornerstones of good health. It affects everything from your weight and blood pressure to your energy and mood. If you have been struggling with an ongoing sleep problem, then a sleep study may be just what you need. It could be the key that unlocks the door to a dramatic improvement in your health and a better quality of life for you.
Losing sleep over the economy, but losing sleep over an undiagnosed problem is no fun.
People are notorious for underestimating how sleepy they are. People assume that thier disrupted sleep and level of sleepiness when awake is normal for their age. Symptoms of some sleep disorders also can go unnoticed. For example loud snoring and gasping for breath durning sleep are two warning signs for sleep apnea. But you may be unaware of these sym if you live or sleep alone. As a result, millions of people go through each day wondering why they can’t stay awake. Others go to bed each night wondering why they can’t sleep. The answers to these questions often can be found by a sleep study…
Here are some benefits to think about:
Research shows that there are numerous benefits to detecing a sleep disorder with a sleep study. The study pinpoints the nature and cause of your sleep problem. This provides the foundation for an effective treatment plan. Treating a sleep disorder promotes heath, productivity and well-being. In the long run it also can save you money!
- Improved Health
Research has linked sleep disorders to many other health problems. These include heart disease, high blood pressure, stroke, diabetes and obesity. A study in the journal Sleep even shows that people with severe, untreated sleep apnea have five times the risk of dying from a heart problem. Effective treatment of a sleep disorder can reduce the risk and severity of other related health challenges.
- Reduced Spending
Studies have linked undetected and untreated sleep disorders to an increase in health-care utilization and spending. You are likely to make more visits to the doctor’s office each year. You are also likely to spend more money on your health care. Expenses may include testing, medications and hospitalization. Research shows that effective treatment of a sleep disorder can reduce your health-care spending. Compared to the high cost of remaining untreated, treating most sleep disorders is relative inexpensive.
- Greater Productivity
Studies have linked sleep disorders to lower productivity and more absences at work. A severe sleep disorder may even prevent you from being able to stay employed. Effective treatments of a sleep disorder can enable you to improve your job performance.
- Better Safety
Research has linked sleep disorders to an increased risk of work-related injuries and motor-vehicle accidents. Effective treatments promotes your safety at work on the roads.
- Improved Quality of Life
Sleep disorders can take a severe tool on your personal well-being. Taking care of yourself leads to improvements in your mood, attitude, energy, memory and overall outlook on life. Sleep disturbances can put strain on your relationships.

The wise words of Wilse Webb, a prominent sleep researcher recently said.
So, question of pose: How long can humans stay awake?
The experiemental answer to this question is 264 hours (about 11 days). In 1965, Randy Garder, a 17 year-old high school student, set this apparent world-record for a science fair. Several other normal research subjects have remained awake for eight to 10 days in carefully monitored experiments. None of these individuals experienced serious medical, neurological, physoiological or psychiatric problems.
On the other hand, all of them showed progressive and significant deficits in concentration, motivation, perception and other higher mental processes as the duration of sleep deprivation increased. Nevertheless, all experimental subjects recovered to relative normality within one or two nights of recovery sleep. Other anecdotal reports describe soldiers staying awake for four days in battle, or un-medicated patients with mania going without sleep for three to four days.
The more difficult answer to this question revolves around the definition of “awake.” As mentioned above, prolonged sleep deprivation in normal subjects induces altered stated of consciousness ( often described as “microsleep”), numerous brief episodes of overwhelming sleep, and loss of cognitive and motor functions. We all know the dangerous, drowsy driver, and have heard about drowsy flyers crashing planes because they fell asleep while flying. RandyGardner was “awake” but basically cognitively dysfunctional at the end of his ordeal.
In certain rare human medical disorders, the question of how long people can remain awake raises other surprising answers, and more questions. Morvan’s fibrillary chorea or Morvan’s Syndrome is characterized by muscle twitchings, pain, excessive sweating, weight loss, periodic hallucinations, and severe loss of sleep ( agrypnia ). Michel Jouvet and his colleagues in Lyon, France, studies a 27 year-old man with this disorder and found he had virtually no sleep over a period of several months. During that time he did not feel sleepy or tried and did not show any disorders of mood, memory, or anxiety. Nevertheless, nearly everynight between 9:00 and 11:00 p.m., he experienced a 20 to 60-minute period of auditory, visual, olfactory and somesthetic (sense of touch ) hallucinations, as well as pain and vasoconstriction in his fingers and toes. In recent investigations, Morvan’s Syndrome has been attributed to serum antibodies directed again by specific potassium (K+) channels in cell and nerve membranes.
So, to return to the orginal question, “How long can humans stay awake?” the ultimate remains unclear. Despite studies, there are no reports that sleep deprivation per se has killed any humab ( excluding accidents and so forth ). Indeed, the U.S. Departmend of Defense has offered research funding for the goal of sustaining a fully awake, fully functional “24/7” soldier, sailor, or airman. Future warriors will face intese, around the clock fighting for weeks at a time. Will bioengineering eventually produce genetically cloned soldiers and citizens with a variant of Morvan’s Syndrome who need no sleep but remain effective and happy? I hope not. A good nights sleep is one of life’s blessings.
As Coleridge wrote years ago, “Oh sleep! It is a gentle thing, beloved from pole to pole.”
