Exercise Can Strengthen the Brain

Can exercise make the brain more fit? That absorbing question inspired a new study at the University of South Carolina during which scientists assembled mice and assigned half to run for an hour a day on little treadmills, while the rest lounged in their cages without exercising.

Earlier studies have shown that exercise sparks neurogenesis, or the creation of entirely new brain cells. But the South Carolina scientists were not looking for new cells. They were looking inside existing ones to see if exercise was whipping those cells into shape, similar to the way that exercise strengthens muscle.

For centuries, people have known that exercise remodels muscles, rendering them more durable and fatigue-resistant. In part, that process involves an increase in the number of muscle mitochondria, the tiny organelles that float around a cell’s nucleus and act as biological powerhouses, helping to create the energy that fuels almost all cellular activity. The greater the mitochondrial density in a cell, the greater its vitality.

Past experiments have shown persuasively that exercise spurs the birth of new mitochondria in muscle cells and improves the vigor of the existing organelles. This upsurge in mitochondria, in turn, has been linked not only to improvements in exercise endurance but to increased longevity in animals and reduced risk for obesity, diabetes and heart disease in people. It is a very potent cellular reaction.

Brain cells are also fueled by mitochondria. But until now, no one has known if a similar response to exercise occurs in the brain.

Like muscles, many parts of the brain get a robust physiological workout during exercise. “The brain has to work hard to keep the muscles moving” and all of the bodily systems in sync, says J. Mark Davis, a professor of exercise science at the Arnold School of Public Health at the University of South Carolina and senior author of the new mouse study, which was published last month in The Journal of Applied Physiology. Scans have shown that metabolic activity in many parts of the brain surges during workouts, but it was unknown whether those active brain cells were actually adapting and changing.

To see, the South Carolina scientists exercised their mice for eight weeks. The sedentary control animals were housed in the same laboratory as the runners to ensure that, except for the treadmill sessions, the two groups shared the same environment and routine.

At the end of the two months, the researchers had both groups complete a run to exhaustion on the treadmill. Not surprisingly, the running mice displayed much greater endurance than the loungers. They lasted on the treadmills for an average of 126 minutes, versus 74 minutes for the unexercised animals.

More interesting, though, was what was happening inside their brain cells. When the scientists examined tissue samples from different portions of the exercised animals’ brains, they found markers of upwelling mitochondrial development in all of the tissues. Some parts of their brains showed more activity than others, but in each of the samples, the brain cells held newborn mitochondria.

There was no comparable activity in brain cells from the sedentary mice.

This is the first report to show that, in mice at least, two months of exercise training “is sufficient stimulus to increase mitochondrial biogenesis,” Dr. Davis and his co-authors write in the study.

The finding is an important “piece in the puzzle implying that exercise can lead to mitochondrial biogenesis in tissues other than muscle,” says Dr. Mark Tarnopolsky, a professor of medicine at McMaster Children’s Hospital, who was not involved with this experiment but has conducted many exercise studies.

The mitochondrial proliferation in the animals’ brains has implications that are wide-ranging and heartening. “There is evidence” from other studies “that mitochondrial deficits in the brain may play a role in the development of neurodegenerative diseases,” including Alzheimer’s and Parkinson’s diseases, Dr. Davis says. Having a larger reservoir of mitochondria in your brain cells could provide some buffer against those conditions, he says.

Dr. Tarnopolsky agrees. “Epidemiological studies show that long-term runners have a lower risk of neurological disease,” he points out.

More immediately, Dr. Davis speculates, re-energized brain cells could behave like mitochondrial-drenched muscle cells, becoming more resistant to fatigue and, since bodily fatigue is partly mediated by signals from the brain, allowing you to withstand more exercise. In effect, exercising the body may train the brain to allow you to exercise more, amplifying the benefits.

Revitalized brain cells also, at least potentially, could reduce mental fatigue and sharpen your thinking “even when you’re not exercising,” Dr. Davis says.

Of course, this experiment was conducted with animals, and “mouse brains are not human brains,” Dr. Davis says. “But,” he continues, “since mitochondrial biogenesis has been shown to occur in human muscles, just as it does in animal muscles, it is a reasonable supposition that it occurs in human brains.”

Best of all, the effort required to round your brain cells into shape is not daunting. A 30-minute jog, Dr. Davis says, is probably a good human equivalent of the workout that the mice completed.

Self Help Tips For Happiness And Success

Your willpower can help you find more positive things in your life. Your attitude towards others will affect what happens to you. Make a decided effort to hope for the best in those around you. When you look on the bright side, it is harder for negative emotions and unfortunate events to ruin your mood.

Sexual capital is an important new trait undergoing research. This simply means the ability to use your charm (not sexuality) to get what it is that you want. Not everyone is good in a social environment, though having sexual capitol can help in many aspects of life.

You need to know that you deserve the best when you are embarking on a journey of personal development. Repeat this statement to yourself every day, "I owe it to myself to strive for the best". You will not regret anything if you know that you have done everything that you can do.

You should make personal development goals as defined as possible with specific ways to achieve them. If you set goals that are clearly laid out, you will improve your chances of meeting or surpassing them. You will have an easier time overcoming your challenges and you will be able to have success quicker.

One simple step to your personal development is doing things for the benefit of other people. If you direct your energy outward to make others' lives better, while temporarily putting your own needs second, you can greatly improve your character. Being able to make sacrifices for others without hurting yourself will help you become the person you want to be.

Always make your own decisions, so you do not miss any opportunities that life is providing you. Make decisions based on your own knowledge and what you can learn from your research. Positive habits are formed through the instances where you make a successful decision, which in turn becomes a more "natural instinct". You can even learn a lot from making mistakes because you then know what not to do. A bad choice will just open up the door for a better one.

It may become discouraging to begin developing better personal habits and lifestyles, but once you start noticing your life developing towards a better future, you will never want to stop. You can always develop better ways to do things and it's important to always try hard towards any personal development goals you have.

4 Easy Ways to Stop Hair Loss

Hair loss is a common problem for both men and women. This can leave the person feeling bad to an extent that he or she stops going out for fear about what people are going to say about him. Although hair loss is believed to be a medical and hereditary condition, there are some tips which you can follow to stop hair loss. Make sure to consult your doctor before you tart a hair loss program so he can identify the cause and advise you on the best hair loss treatments.

How to Stop Hair loss?

Hair care

Using the right hair care products can help to stop hair loss. Avoid changing hair care products after every week since this can weaken your hair resulting in hair loss. If you are one of those people who like to change their hair color frequently, you should do this after 6 to 8 weeks. Coloring your hair frequently can result in massive loss since the products used contain harmful chemicals. You can also look for shampoos that can stop hair loss, use the right comb and avoid combing your hair while it is still wet. Keep in mind that hair styles such as ponytail and braiding can result in excessive hair loss. You should therefore avoid any style that can pull your hair. In addition, avoid using harsh chemicals to perm or bleach your hair since the chemicals used can weaken the roots of the hair to cause hair loss.

Healthy diet

The food you eat plays a crucial role in hair loss. You will need to feed on a diet that is rich in protein, calcium and vitamins to stop hair loss. Taking these diets leaves the hair root strong enough to stop breakage every time you comb your hair. Some of the foods you can eat include fruits, green leafy vegetables, milk, spinach, almonds, fish, tomatoes, eggs and yogurt. You can also take proteins and vitamin supplements which are sold over-the-counter in drug stores.


Aromatherapy is another hair loss solution that involves massaging hair oils into the roots of the hair. You can use oils such as lavender, rosemary and olive oils which will not only strengthen the hair, but will also leave it looking strong and shiny. Olive oils stop hair loss by strengthening the hair follicles.

Drink enough water

Drinking adequate water in a day can stop hair loss. Water will keep your hair hydrated to prevent it from breaking when you comb it. Take at least 8 glasses of water in a day and go to sleep for 7 to 8 hours. Lack of enough sleep can result in stress which is one of the main causes of hair loss.

There are some simple measures which you can take to stop hair loss. They include taking a healthy diet, drinking water and massaging essential oils into the hair. In addition, wash your hair with shampoo and conditioner. These are natural remedies which do not have any side effects. However, you should consult your doctor before embarking a hair loss prevention program for effective outcomes.
