There’s new research from the University of California that states the problems surrounding older people and their sleep, while offering few solutions. This is a somewhat sad trend when it comes to research affecting the aging members of our society. When people are younger and more energetic, they will contribute to the growth and development of the American way of life. Equally important is their personal earning capacity. To maintain their quality of life, they will often pay the medical profession well. Those who are older have less to contribute and, while some do have money, there’s less that can be done to improve the quality of life when bodies have aged. Although Sarah Palin was exaggerating the threat of “death panels” to drum up opposition to reform, we have a comparable effect already in the rationing of research into the health problems of the old, and in the poor quality of healthcare services in the geriatric sector. People do have shorter lives in the US than in many other countries around the world.

According to the research, about half the seniors in the US complain of difficulty in sleeping. It’s suggested that lack of sleep increases the risk of illness and early death. The question, therefore, is why seniors do find sleep more difficult. The answers are not directly related to age as such, but to the facts that older people are more prone to diseases and disorders, use more medications which have insomnia as a side effect, and find their circadian rhythms disrupted. Unfortunately, the research also finds the healthcare service is not sympathetic to these problems and fails to properly diagnose sleep disorders or give the appropriate treatment (including simply adjusting the dosages in medications probably contributing to the sleep disorder). At present, there’s no financial incentive for hospitals and clinics to divert resources to treat these problems. Although seniors can use their own savings to go to professional sleep laboratories for overnight assessment with a polysomnogram, the necessary follow-up treatments through counseling and cognitive behavioral therapy is often neglected because it’s not considered cost-effective. Necessary dentistry or, where appropriate, surgery is a one-off cost and preferred where appropriate. But, for the most part, seniors are left to fend for themselves.

The University of California is unable to offer any solutions to these problems. The dominance of capitalism in the healthcare industry means service providers will make the decisions giving them the best profit opportunities. Seniors do not fit into this system. They do better under systems of socialized medicine. The result is that American seniors are driven into the waiting arms of the pharmaceutical industry. Those who worry about lack of sleep rather than adapting to a different flow of life buy ambien online. This is the cheap solution to their problems. Ambien works within about ten minutes of taking the pill and lying down. Whether in conventional form or as ambien cr, seniors can then sleep through the night. It’s not the ideal solution and the continuing cost can slowly drain savings. But, in a culture that’s relatively uncaring, there should be no expectation of entitlement to quality of life. In America, you get what you pay for.

For some, there are threats everywhere. They fear the world is dangerous and, unless they stay in a constant state of vigilance, their lives will be at risk. In a small number of cases, this gets out of control and tips into paranoia and mental disorder. For the majority, it”s an exaggerated caution because they do not understand how modern technology works. They see how dangerous electricity can be and so are cautious when using powered equipment, particularly when that involves the use of “radiation”. Now there”s a word to get the conspiracy theorists into action. Yet, from a scientific point of view, you cannot escape the fact that television and computer screens give off electromagnetic radiation (EMR), handphones rely on microwave broadcasts, and then there”s light. In coherent form as a laser, it can potentially blind people. As it shines from the sun, we can see our way and, with appropriate protection from ultraviolet, live healthy lives.

The white light we “see” is in fact made up of all the colors blended together. Each color has a property of its own and you may have seen increasing publicity given to light as a treatment for skin problems like acne. When it”s projected from a TV or computer screen, you get both the EMR and light in the visible spectrum, often with a slightly bluish tinge. For the treatment of skin problems, blue and red are used. For the treatment of sleep disorders, blue and green are being used in a series of clinical trials. It”s perhaps slightly ironic, but those who felt an effect from television and computer screens were probably right, except that the effect seems to be beneficial if you want to change your sleeping times.

We know when to sleep because our internal clock is set to match the local daily cycle. If we move to different time zones so that morning is now night, this confuses us and we find it difficult to match local time for sleep. As a trial, a number of people were cut off from the world in rooms without windows or clocks. There was no way for them to tell how much time was passing. The research team kept them awake for fifty hours and then allowed sleep for eight. When awake, half were exposed to blue light, the other to green. All the participants were carefully monitored and it was found that both colors could reset the internal clocks. The only difference between the two groups was that dim blue and bright green lights were less effective. The relevant neurotransmitters and hormones responded more precisely to bright blue and dim green.

So, in all situations where the sleep problem is caused by the body”s circadian rhythms not being properly synchronised to local time, the use of light may well prove the best long-term solution. Although a drug like ambien can and does produce sleep “on demand”, there are always problems if you come to depend on a drug for any long-term solution. Ambien will always help you get needed rest, but the use of alternative methods is preferable. As counseling and therapy is expensive and often not covered by health insurance plans, the development of light treatment may come as a simple and cheap solution to sleep problems.
