Are you looking for another reason to exercise? Exercise can improve your life by increasing creativity, focus and intelligence.

Many people look at exercise as a requirement.  They know they are supposed to exercise, but they don’t necessarily enjoy it.  As a result, many dieters find that they are forcing themselves to exercise.  On the other hand, often people who aren’t trying to lose weight skip exercising altogether.  As you know, everyone should exercise because there are countless health benefits to exercising, which include fighting diseases like stroke, osteoporosis, diabetes and high blood pressure.

However, it is important to realize that exercise can improve your life in ways that are not necessarily even fitness related.  Exercise can allow you to find solutions, boost creativity and improve your focus.

A recent study at the National Cheng Kung University in Taiwan showed that the brainpower of mice improves when they are allowed to exercise. When mice are forced to exercise more than they normally would, the mice’s thinking power improves yet further.  Scientists noted major developments in the brain when the mice were pushed beyond their natural exercise inclinations.

So does the brainpower improve because of increased blood flow to the brain?  Interestingly, a recent study out of Columbia University and the Salk Institute showed that exercise’s improvements in focus and thinking result from more than just blood flow.  Scott Small and Fred Gage conducted this experiment.  They found that during exercise, muscles contract and chemicals and proteins are released.  One protein called IGF-1 releases chemicals in the brain that stimulate neurons to branch out in new directions. The end result is new connections between our brain cells.  These new connections are responsible for making us smarter!

As you boost your focus and mental ability, you also boost your creativity when you exercise.  Keith Sawyer, PhD the author of the book Group Genius: The Creative Power of Collaboration stated “Physical activity gets your mind into the bodily experience, so that subconscious connections can pop up.”  Exercise also releases cortisol from your body.  If there is too much cortisol in your system caused by stress, your ability to be creative shuts down.

Make sure that you do not force too much exercise on yourself.  After all, overtraining can lead to injuries and can be counterproductive to improving your life.  Exercise for at least 30 minutes at a time.  If you are looking to find creative ideas, consider exercising alone as an exercise companion may distract you.  Bring a small notepad and jot down ideas.

Once you understand these benefits of exercising, you will be more likely to want to integrate exercise in your daily routine.  If you are having difficulty focusing or being creative, you will quickly find that exercise can be the solution to your problems.

How is it possible for evolutionary selection to favor genetic variants beneficial in human old age, long after reproduction is impossible? An open access paper examines this question: "Evidence points towards the existence of a strong heritable component of human longevity. Around a quarter to a third of the variability of lifespan can be attributed to the action of genes. One of the best examples of a gene affecting survival in old age is the apolipoprotein E gene APOE. ... One of the major ideas in the evolutionary theory of ageing is the suggestion that, because the force of natural selection declines with age, alleles with deleterious effects seen only at older ages can reach higher frequencies than those that have their effects earlier in life. Therefore, if a gene exerts an effect only after the end of the reproductive phase of the lifespan it has been thought unlikely that it could have been subject to significant direct selection pressure ... It is often claimed that genes affecting health in old age, such as cardiovascular and Alzheimer diseases, are beyond the reach of natural selection. We show in a simulation study based on known genetic (apolipoprotein E) and non-genetic risk factors (gender, diet, smoking, alcohol, exercise) that, because there is a statistical distribution of ages at which these genes exert their influence on morbidity and mortality, the effects of selection are in fact non-negligible."

Via EurekAlert!, another example of testing stem cells and heart regeneration: "Some patients with heart muscles seriously affected by coronary heart disease may soon be able to benefit from an innovative treatment. Researchers [are] evaluating the safety, feasibility and efficacy of injecting stem cells into the hearts of patients while they are undergoing coronary bypass surgery. These stem cells could improve healing of the heart and its function. The IMPACT-CABG (implantation of autologous CD133+ stem cells in patients undergoing coronary artery bypass grafting) protocol evaluates this experimental procedure, which is destined for patients suffering from ischemic heart disease, in which the blood supply to the heart is decreased and associated with heart failure. These patients undergo open-heart coronary bypass surgery, performed by the medical team to improve perfusion of the heart muscle. A few weeks ago, the first patient received progenitor CD133+ stem cells isolated from his bone marrow and enriched, [and] has been doing very well ever since. Already, improvement has been noted in the contraction capacity of his heart, which has improved its ability to pump blood."

Eating small doses of chocolate has been shown to lower your risk of a stroke or heart attack.

A new study indicates that eating chocolate each day can be good for your heart.  According to this study from the German Institute of Human Nutrition in Nuthetal, Germany, eating small amounts of chocolate can reduce your risk of a stroke or heart attack by 40%.

To obtain their results, German scientists followed 20,000 people over eight years.  They sent them a daily questionnaire about their diet and exercise.  The people in this survey had no history of heart disease and had similar healthy habits.  Researchers found that those who ate about a square of chocolate a day obtained these positive results of a lower risk of stroke or heart attack.

Experts theorize that it is the flavonols in chocolate that are having this positive impact.  Flavonols can cause muscles in blood vessels to widen and thus lower blood pressure.

Brian Buijsse from German Institute of Human Nutrition stated, “It’s a bit too early to come up with recommendations that people should eat more chocolate, but if people replace sugar or high-fat snacks with a little piece of dark chocolate, that might help.”

Of course, don’t take these findings as an excuse to go out and gorge on chocolate!  Eating large amounts of chocolate can quickly pack on the pounds.  Also when you are choosing chocolate, be sure to opt for a choice with high cacao content.  Avoid milk chocolate bars from the grocery store as have a lower ratio of the beneficial elements.  They are also packed with sugar and often include artificial ingredients as well.

Aside from lowering your risk of stroke and heart attack, dark chocolate has other beneficial properties.  It boosts good cholesterol and lowers stress and anxiety.  The flavonoids in chocolate have also been shown to fight aging.

A new European study releases their findings that teens can override the effect of the “fatso gene” through at least one hour per day of exercise.

A new European study whose results are published in the April edition of Archives of Pediatrics and Adolescent Medicine states that exercising just one hour per day can help teenagers to override the effects of the “fatso” gene.

There is no doubt that the obesity gene can make people gain weight.  One gene called the “FTO gene” has a particularly strong impact.  People with 2 copies of this gene weigh about 7 more pounds on average.

The EU and Spanish and Swedish governments funded this study which sought to find out if recommending one hour of exercise to teens was beneficial in fighting the effects of the fat gene.  Researchers had 752 teenagers wear a device, which monitored their physical activity.

As it turned out, those who had the obesity gene weighed the same as those without it… as long as they exercised.  However, if the teens had the gene and exercised less than one hour per day, they always had more fat and larger waistlines.

This new study supports the current advice given to children and teens in the U.S., which is to get one hour of physical exercise, preferably aerobic exercise, per day.

Dr. Alan Shuldiner of the University of Maryland, stated “The message is clear: genes are not destiny. Those with obesity susceptibility genes should be especially motivated to engage in a physically active lifestyle.”

This study is very good news.  As it turns out, even teens with the fat gene, are not destined to a life of obesity.  They can control their fate to some extent.

Of course, the fact of the matter is that everyone, not just teens, should be exercising every day.  The reasons are quite vast.  Exercise improves your mood and quality of life.  It can improve your sleep and boost your energy level.

Exercise has also been shown to prevent a variety of diseases, everything from certain types of cancer to heart disease to osteoporosis.

Greater understanding of the immune system means a greater ability to reprogram its components – such as errant immune cells that cause autoimmune diseases. From EurekAlert!: a study “describes a unique therapeutic ‘nanovaccine’ that successfully reverses [type 1] diabetes (T1D) in a mouse model of the disease. In addition to providing new insight into diabetes, the research also reveals an aspect of the pathogenesis of the autoimmune response that may provide a therapeutic strategy for multiple autoimmune disorders. … [Researchers] wanted to find a way to counteract the harmful autoimmune response without compromising general immunity. They discovered that our bodies have a built-in mechanism that tries to stop the progression of autoimmune diseases like T1D. Essentially, there is an internal tug-of-war between aggressive T-cells that want to cause the disease and weaker T cells that want to stop it from occurring … The researchers also developed [a] nanotechnology-based ‘vaccine’ that selectively boosted the weak white blood T cells, enabling them to effectively counter the damage caused by their overactive T cell relatives. … their nanovaccine blunted T1D progression in prediabetic mice and restored normal blood sugar in diabetic mice. … If the paradigm on which this nanovaccine is based holds true in other chronic autoimmune diseases, such as multiple sclerosis, rheumatoid arthritis, and others, [nanovaccines] might find general applicability in autoimmunity.”
