(Source: American Academy of Sleep Medicine ) An acute session of moderate aerobic exercise, but not heavy aerobic or moderate strength exercises, can reduce the anxiety state and improve the sleep quality of insomnia patients, according to a research abstract that will be presented on Wednesday at SLEEP 2008, the 22nd Annual Meeting of the Associated Professional Sleep Societies (APSS).

The study, authored by Giselle S. Passos, of Federal University of Sao Paulo in Brazil, focused on 36 patients (eight men and 28 women) with primary chronic insomnia, who were divided into three experimental groups (moderate aerobic exercise, heavy aerobic exercise, and moderate strength exercise) and a control group.

According to the results, after the exercise session, reductions were shown in sleep onset latency (54 percent) and wake time (36 percent) in the moderate aerobic exercise group, while increases were shown in total sleep time (21 percent) and in sleep efficiency (18 percent). A significant increase in the total sleep time (37 percent) and reduction in the sleep onset latency (40 percent) were observed in the sleep log of volunteers of the moderate aerobic exercise group. Finally, a significant reduction (seven percent) in the anxiety state was also observed after moderate aerobic exercise session.

“These findings indicate that there is a way to diminish the symptoms of insomnia without using medication,” said Passos. “This study is the first to look at the importance of using physical exercise to treat insomnia, and may contribute to increased quality of life in people with one of the most important kind of sleep disorders around the world.”

Insomnia is a classification of sleep disorders in which a person has trouble falling asleep, staying asleep or waking up too early. It is the most commonly reported sleep disorder. About 30 percent of adults have symptoms of insomnia. It is more common among elderly people and women.

It is recommended that adults get between seven and eight hours of nightly sleep.

The American Academy of Sleep Medicine (AASM) offers the following tips on how to get a good night’s sleep:

Follow a consistent bedtime routine.

Establish a relaxing setting at bedtime.

Get a full night’s sleep every night.

Avoid foods or drinks that contain caffeine, as well as any medicine that has a stimulant, prior to bedtime.

Do not bring your worries to bed with you.

Do not go to bed hungry, but don’t eat a big meal before bedtime either.

Avoid any rigorous exercise within six hours of your bedtime.

Make your bedroom quiet, dark and a little bit cool.

Get up at the same time every morning.

Those who suspect that they might be suffering from insomnia, or another sleep disorder, are encouraged to consult with their primary care physician or a sleep specialist.

Climb Your Way Up The ‘Disturbed Way Of Handling Carbohydrates’ Tree

The original 1972 book that made Dr. Atkins famous! Sometimes I don’t even think we realize just how brilliant the late great Dr. Robert C. Atkins really was for espousing what he did during his amazing career. Sure, low-carb diets had been out there in the public eye for over a century (most notably from William Banting in 1864 with his Letter On Corpulence) before he came along. But it was the charisma and enthusiasm for the low-carb lifestyle that Dr. Atkins brought to the public arena that captured the attention of millions of people worldwide who were interested in learning more about how low-carb could help them shed the pounds and restore their good health.

Hey NIH, Lower Blood Sugar In Diabetics Is A GOOD Thing!

If you care about diabetes health, then sign this petition! We all know how incompetent many of the government and leading health organizations are in the United States as it relates to providing information to the public about taking care of themselves to protect against disease and death. We’ve seen it with the failed low-fat, low-calorie diets they’ve been pushing on the American people for decades with no positive impact whatsoever and yet they continue to promote it as the only way to control obesity and health. If the definition of insanity is doing the same thing over and over again expecting a different result, then I do believe we can officially describe those in charge of health policy in America as INSANE!

Forgetful? Exercise Can Keep Memory Sharp

(Source: American Medical Association. JAMA) Adults with memory problems who participated in a home-based physical activity program experienced a modest improvement in cognitive function, compared to those who did not participate in the program, according to a study in the September 3 issue of JAMA. As the world population ages, the number of older adults living with Alzheimer disease (AD) is estimated to increase from the current 26.6 million to 106.2 million by 2050. "If illness onset could be delayed by 12 months, 9.2 million fewer cases of AD would occur worldwide. For this reason, attempts have been made to identify individuals who are at increased risk of AD and to test interventions that might delay the progression of prodromal symptoms [early non-specific symptom, or set of symptoms] to full-blown dementia," the authors write.
