You Are What You Sleep

Lack of sleep can lead to childhood obesity

Stressful lifestyles often contribute to physical disorders and psychological difficulties, but little has been known about the fact that unbalanced sleep patterns also dysbalance a healthy body weight. Jean-Philippe Chaput of Laval University, Quebec City presented some facts at the 16 th European Congress on Obesity in Geneva, that emphasizes the importance of a balanced sleep pattern. There can be not only too little sleep but also too much sleep, as Dr. Chaput found out by studying 276 adults. Those who had a pattern of short duration sleep (5 to 6 hours) and those individuals who slept 9 to 10 hours were 35% and 25% more likely, respectively to show weight gains of 5 kg compared to the group that slept for 7 to 8 hours. The most likely reason is an alteration of certain hormones: short sleepers had high leptin levels and low ghrelin levels. In a previous study on children it also became obvious that to little sleep increases the risk of overweight and obesity in children. It was also possible to establish the type of weight gain.

Short sleep duration in kids lead to abdominal fat rather than to overall body fat deposits. Too little sleep in children seems to have more health consequences than previously thought, as it is the most important risk factor for overweight in this group. The most important risk factor was sleep duration that is too short, followed by parental obesity, watching TV and lack of physical activity.

Emotional Distress Impairs Cognitive Function

Stress has been linked to numerous medical conditions, such as heart disease, stomach problems and muscle spasm. Stress also has been quoted as a silent killer.

Research in the field of Alzheimer’s has shown that negative emotions and chronic distress are associated with increased vulnerability to this disease.

Study author Dr. Robert Wilson of the Rush’s Alzheimer’s disease Center in Chicago has found that people most prone to psychological distress were 40% more likely to develop mild cognitive impairment (MCI) than the group that is least distress prone.

Dr. Wilson stated that these individuals would not necessarily see a psychiatrist to help them deal with their negative emotions. It becomes clear, however, that persistent negative emotional states truly impact the physical well being, and also the cognitive status. For this reason more medical attention should be given to an older patient with emotional problems and even mild depression.

It can become a treatment challenge, if there are personality traits or deeply entrenched behavior patterns that may not respond well to treatment. By understanding the biological link between chronic distress and loss of cognitive function in old age, early intervention can be a way to delay symptoms or to prevent disease onset.

More Is Not Always Better In Exercise

Physical activity and good nutrition are the keys for a healthy immune system. Dr. David Nieman, PhD, from the Appalachian State University of Boone, N.C. has found that exercise and nutrition play a strong role in boosting immunity. His past research showed that women who walked briskly for 30 to 45 minutes five days for 12 to 15 weeks had colds half as often as inactive women. This is true even for the aging population, where immunity tends to decline; some research has shown that fit elderly people have better-preserved immune systems.
It is tempting to conclude, that more exercise would lead to even better benefits, but the research results are quite different. Exercising for too long (beyond 90 minutes) appears to cause a steep drop in immune function that can last up to 24 hours. In the 1987 Los Angeles Marathon, Dr. Nieman surveyed 2,311 runners and found those who raced were six times more likely to get sick afterward compared with those who dropped out of the race for non-medical reasons. Runners who trained more than 96 km per week during the two months before a race doubled their chances for sickness compared with those who trained less than 36 km per week.
In lab tests on marathon runners who ran on a treadmill for 90 minutes to 3 hours at 80% aerobic capacity, the level of immune cells had decreased (neutrophils, monocytes, natural killer cells, T cells and B cells). All these players in the immune system leave the blood and concentrate on the effort to do repairs and maintenance on the muscles. As a result the front line soldiers are unavailable for defense when viruses are present.

The best strategies for active as well as not-so-active individuals remain similar.
-Minimize life stresses-mental and emotional.
-Avoid over training and chronic fatigue.
-Curb exercise if you have a fever or systemic infection.
-Eat a well-balanced diet with adequate energy.

Men Expected to Catch Up On Life Expectancy

Life expectancy between the sexes has always been different: females generally outlive males by several years, but close observation from the Office of Health Economics in Great Britain shows a shift in Life expectancy. Males have been catching up, and their life expectancy rates have been rising faster than those of females. There is still a difference for a boy born in 2002. He will have a life expectancy of 76 years, whereas his sister will live to age 81.

Researchers believe that the reason for the shift is lifestyle change in females. Many of them now face the same workplace stress that has been traditionally shouldered by males. Detrimental habits are also more common in females. Heavy drinking in young females has more than tripled in the last 17 years, and 10% of young females exceed the recommended drinking limit (compared to 12% males). Non-smoking campaigns are less successful in women. Males have cut their smoking habits. 51% smoked in 1974, and by 2002 only 28 % were smokers. Female smokers amounted to 41 % in 1974, but by 2002 there were still 26 % smokers. The results show most dramatically in cancer statistics. Since 1973 lung cancer rates in men have been reduced to half and the lung cancer survival rate has increased. In comparison lung cancer in females during the same time period has increased by 45%. As a result of sedentary lifestyles the body mass index has also shown an increase.

Estimates showed that by the year 2010, life expectancy will likely converge for both sexes at an age of 81.

Sleep More For Healthy Body Weight

Sleep deprivation is a common problem in a society governed by stress and hurry. Less hours of sleep may give us the illusion of being more effective, but it seems to be at the expense of our health. Lack of sleep affects our brain metabolism in various ways, and researchers at Columbia University recently examined data on 6115 people, ages 32 to 59 from a U.S. National Health and Nutrition Examination Survey. The findings were presented at a recent meeting of the North American Association for the Study of Obesity. Of those who slept less than four hours per night 73% were more likely to be obese. Those who slept six hours per night were 23% more likely to be obese. The findings further suggested that in people who sleep less than eight hours per night (about three quarter of the 1024 participants), body mass index was inversely proportional to sleep duration.

The researchers also reported the reasons for that. Sleep deprivation lowers leptin, a blood protein that suppresses appetite and sends the signal, when the body had enough food. Lack of sleep also raises ghrelin levels, a polypeptide hormone from the stomach wall, which makes people want to eat. Laboratory tests of one study showed that making do with only four hours of sleep resulted in an 18% reduction of the leptin (the “appetite stopper”) and a 28% increase of the ghrelin (the “appetite animator”). Translated into plain text, it means that the breaks were removed and the signal given to eat by 46% more than in persons with a sufficient dose of sleep.

In addition sleep deprived healthy persons in their 20’s also craved more sweets and starchy foods than well-rested individuals and these added calories are stored as body fat. These hormonal changes are the biochemical evidence pointing to the connection of a sleep-deprived lifestyle with obesity and the associated health problems like diabetes and cardiovascular illness.
Drastic diets don’t seem to hold the answer. Part of the entire picture may be as simple as sleeping more and as a result weighing less.

Harp Music After Heart Or Chest Surgery Reduces Pain By Seventy Percent

Believe it or not: Harp music following serious chest or heart surgery in 17 patients leads to pain relief according to Aragon and colleagues. They reported this mid September 2002 (Altern Ther Health Med 2002;8:p.52-60) and they were measuring blood pressure, pulse, respiratory rate as well as pain and anxiety by psychological assessments to measure the effect on pain perception after listening to 20 minutes of harp music. The pain reduction was about 70% at the end of a 20 minute session and lasted at least 10 minutes (when the 20 minute and 30 minute point from the beginning of the harp music session were compared). This experiment documents the relaxation response, which is known from hypnotherapy as well and can also be brought on by meditation, yoga or prayer. The authors suggest that music therapy following surgeries could be utilized to promote healing and to reduce complications. Other health care settings where such a therapy might be useful would be in the treatment of anxiety disorders, where a reduction in anti-anxiety drugs under psychiatric guidance may be achievable.
