New research suggests that sleep disorders like sleep apnea, insomnia, shift work disorder and restless leg syndrome are common among firefighters. Tech Times reported that the study found an association between sleep disorders and certain health problems in firefighters, but failed to prove a cause-and-effect relationship. People who suffer from sleeping disorders primarily complain about how they find it hard to relax enough to fall asleep as well, as well as their inability to achieve continuous sleep throughout the night.
Several potential causes for sleep disorders have been cited, including poor working environments, an unhealthy diet, a sedentary lifestyle, depression, and stress. A separate category of this sleep disorder is hypersomnia, which causes excessive sleep times and can be just as harmful, and can possible result in obesity, anxiety, depression, reduced reaction time, and an increased risk of catching diseases. Treatment for chronic insomnia requires a thorough physical exam conducted by a sleep physiology expert to determine any underlying medical conditions that might cause the insomnia. Sleeping in a humid or damp environment has been identified as one possible cause for insomnia sufferers by Janson et al. Prior to this, only a single study had explored the link between room dampness and sleeping disturbances.
Reducing humidity in the sleeping environment can have a massively beneficial effect by preventing the development of such underlying medical disorders that have been known to cause insomnia due to the discomfort associated with them.
Several external factors can be identified that influence the body’s temperature and incidence of sleeping disorders, including the type of bedding as well as bath water temperatures. The type of bedding materials use on the bed can strongly influence a person’s ability to initiate and maintain sleep. The work done so far has established that the prevalence of sleeping disorders among the populace of developed countries is becoming increasingly common. A review of the scientific evidence for over-the-counter herbal remedies that are often used to combat sleep disorders such as insomnia has revealed that ‘surprisingly’ little research backs up their safety and efficacy. For some people, symptoms may be temporary, but for others, symptoms are frequently stable and persistent and, if left untreated, may be linked to increased morbidity, such as mental health problems, poor immunity, heart disease, and increased accidents, they said.As a result the management of sleep disorders such as insomnia includes pharmacotherapy and behavioural interventions.
The latest sleep, sleep disorders and insomnia research from prestigious universities and journals throughout the world. Researchers at the Southern Illinois University School of Medicine have written an excellent overview of many animal models of sleep disorders. About UsEstablished in 1981, the Foundation for Biomedical Research (FBR) is the nation”s oldest and largest organization dedicated to improving human and animal health by promoting public understanding and support for humane and responsible animal research.
People suffering from chronic sleep disorders can take part in medical sleep studies that try to discover the root cause behind their sleeping issues. In the future, Bieber and his team would like to detect unconsciousness in sleep, which is an problem that affects diabetics and epileptics. Juniper research predicted that wearables will play a prominent role in healthcare in the very near future and this seems to show that we are one step closer to seeing this reality.

In Australia, sleeping disorders is a large, under-recognised problem – one that has a significant impact on people’s productivity and quality of life. In 2010 an estimated 1.5 million Australians suffered from a sleep disorder, according to the 2011 Deloitte Access Economics report. Sleeplessness (insomnia) is the most common sleeping disorder and most people suffer from it at some point in their lives, says psychiatrist Dr Frans Hugo.


Before popping a sleeping pill, ask yourself how long you’re planning to take them because some medications – especially benzodiazepam sleeping pills such as Valium – are addictive. Sleep apnoea (when you stop breathing for short periods while sleeping) is one of the most undiagnosed medical conditions. Sleep apnoea occurs when fat accumulated around the neck, such as a double chin or slackened muscle tissue, flattens the oesophagus during sleep and blocks the flow of air for 10 to 60 seconds. New research shows a second type of sleep apnoea that has nothing to do with obesity and obstruction, but which is caused by a fault in the breathing control centre of the brain. Sleep clinic experts are able to diagnose both types of sleep apnoea and treat them with an apparatus that blows air into the mouth, ensuring continuous oxygen intake. Doctors warn sleep apnoea sufferers not to use pills or tranquillisers because these drugs could stop them breathing completely. Sleep terror disorder (night terrors) typically occur in children and make nightmares seem tame.
It’s the only movement disorder that occurs only during sleep and which can vary from repetitive cramps or jerking of the knees, ankles and toes to large movements of all four limbs. People with narcolepsy have “nap attacks” during the day, irrespective of how they sleep at night. It sounds like something from a Halloween horror film but REM behaviour disorder develops when the brain fails to temporarily paralyse the muscles during REM sleep. One doctor tells of a patient who knocked herself unconscious by running into a wall at a sleep clinic because she was “trying to catch a ball”. The study also concluded that due to the fact that firefighters are at a higher risk of sleep disorders, this can lead to poor health and increased risk of motor accidents.
Centers for Disease Control and Prevention (CDC) indicates that about 25 percent of Americans complain of occasional sleeping disorder, while about 10 percent of the U.S. Firefighters with sleep disorders also had a higher prevalence of conditions such as cardiovascular disease, diabetes, depression and anxiety. For instance, insomnia - a condition that stops sufferers from getting quality sleep - has been connected to neurological problems.
Interestingly, even simple preparations for sleeping, such as switching off the light can increase the skin’s temperature (Krauchi and Wirz-Justice, 2001).
Bedding textiles surround the sleeping body and provide for heat transfer (Nielsen & Nielsen, 1984), air permeability, moisture regain, type of fabric and fabric moisture content. In my case there is no position that is comfotable for long and I often awake because of pain though I may not have gone to sleep in pain.
Sleep disorders and conditions include nightmares, REM behavior disorders, sleep talking and walking, circadian rhythm sleep disorder, fatigue, narcolepsy, cataplexy, insomnia, bedwetting, snoring, sleep apnea, restless legs syndrome, teeth grinding and various sleep issues that occur as a result of disease.
Narcolepsy research with dogs and mice has led to the discovery of how narcolepsy happens, which has led to new more effective therapies. Sleep disorders affect countless people around the globe and having a good night’s sleep is something they would really like to have. Gerald Bieber, a scientist at Fraunhofer IGD, has created a sleep recognition algorithm to utilize these smartwatch sensors to detect sleep anomalies when they occur, provide data like bedtimes, duration and quality of sleep.

Knowledge gained from basic research into sleep in animals has led to marked advances in the understanding of human sleep, with important diagnostic and therapeutic implications. What this means is that 8.9% of the population are affected – mostly by obstructive sleep apnoea, primary insomnia and restless leg syndrome.


Sleeping pills are a temporary solution at best because, within a few days, the brain “unlearns” how to sleep.
In America, police pulled a driver off the road only to discover the woman had loaded her dogs into the car and driven 40km – in her sleep!
Many people who have PLMD don’t realise their legs and feet move suddenly at night and disrupt their sleep; they just feel tired the next day. In America there have been controversial cases in which sufferers have committed murder or other violent acts because of the disorder.
Researchers into insomnia, however, have rarely examined the role played by sleeping environments and how they affect the neurological system that makes healthy sleep possible.
A damp sleeping environment during childhood increases the possibility of infants developing respiratory problems, as children react negatively to mould in a building and may develop asthma, a major cause of sleep interruptions.
For instance, the studies by Krauchi, Cajochen and Wirz-Justice (1997) and Tikuisis & Ducharme (1996) found that changes in body position from upright position to a supine position when preparing to sleep increases the body temperature.
All these factors should interact together to provide a level of thermal comfort that makes sleeping possible, and a delicate balance between them is important for reducing health complications. I have insomnia but also Tinnitus which I notice much more if I try to go to sleep without the radio or MP3 on. But, we need to understand the basic mechanisms of sleep to develop more effective treatments and therapies.  According to the American Academy of Sleep Medicine, over 80 specific sleep disorders have been identified.
Even fruit flies have been used as animal model for insomnia, complete with daytime sleep-deprivation drowsiness. Now, with the help of smartwatches, researchers will be able to better analyze sleep movement patterns and help doctors in diagnosing sleep disorders and fine-tune their therapies.
At the same time, research guided by human sleep disorders is leading to important basic sleep concepts.
When you read about people dying peacefully in their sleep, it’s often as a result of sleep apnoea. The researchers observed the presence of sleep disorders and their related adverse health and safety outcomes in approximately 7,000 firefighters from 66 different fire departments across the United States.
The major cause of asthma attacks, dust mites, spreads faster when the sleeping environment is damp.
These studies accurately illustrate that an increase in body temperature also increases the sleep-onset latency, meaning that a hotter sleeping environment makes it harder to transition from being awake to sleeping. A relationship between heat loss and sleepiness: effects of postural change and melatonin administration. English Bulldogs and obese Miniature Yucatan pigs are models for sleep apnea, as they exhibit the same interrupted breathing patterns during sleep as humans do.
The firefighters were evaluated for common sleep disorders and other health issues as well.
As discussed above, most types of moisture in the sleeping environment will have negative effects on the body. Furthermore, contrary to common assumptions, wakefulness, rapid eye movement (REM) and non-REM sleep are not mutually exclusive states. Sweating at night, for this reason, will cause several discomforts that typically interrupt sleep, which results in tiredness.
Sleep deprivation is a huge problem – it can lead to significant reductions in work productivity.
