Health with Nature

It’s a sad biological fact of life that as we age, our hair slowly thins. The way it works is quite simple. There’s a natural cycle of growth, resting, shedding and regrowth. It usually takes between eighteen and twenty-four months for each hair to go through this cycle. Each time a hair is shed, the next hair to grow in its place is slightly thinner than the last. Thus, over your lifetime, your hair will move from thick and bouncy, to thin and flat. Worse, after several cycles, no new hair grows from the “old” follicle. So, although there are a number of different causes of hair loss, the most common is simple aging where the hair on your head gets progressively thinner and falls out. In men, this is usually male pattern baldness and it first makes itself known through a receding hairline. A second patch forms on the top of the head leading to the characteristic pattern.

The question most often asked by men is whether, if they have managed to get to forty without showing any signs of the pattern forming, they are “safe” from baldness. From the first paragraph, you will see this question slightly misses the point. Hair loss is unavoidable. No matter what you do or drugs you take, two-thirds of all men start balding by the age of sixty. The percentage rises steadily after that with men retaining only a small area of coverage by the age of eighty. continue reading…

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. continue reading…

Looking in from the outside, it’s easy to imagine the scientific method working well to allow our knowledge to improve steadily. But, more often than not, the results may have several possible interpretations, and sometimes, there’s doubt about whether the results have been fixed to give the maximum advantage to the manufacturer of the drug under test. Sadly, there’s a serious lack of independent research producing unambiguous results. Against this background, we have the results of a trial into the use of a drug to prevent men from developing prostate cancer. A group of men were gathered together. They had either tested positive for Prostate-Specific Antigen (PSA) or they had a positive biopsy confirming a growth. Over a four year period, these men were given either a drug or a placebo with there being 23% fewer confirmed cases of cancer in the drug group. On the face of it, this sounds like really encouraging news. All the more so because, a similar study with a different drug claimed a 25% reduction in the number of confirmed cancers. If drugs can prevent the development of prostate cancer, this reduces the need for surgery and the risk to erectile function. Obviously, removing the need for surgeons to start cutting away the soft tissues around the groin, enables men to maintain their sexual activity levels.

Unfortunately, both studies are controversial because they were either run by or funded by the manufacturers. Once manufacturers are involved in the design and supervision of the research, there’s a conflict of interests. There will be direct financial benefits if the drug on trial is shown as safe and effective. Millions of research and development money will be lost if drugs are found ineffective or actively dangerous. continue reading…
