It's human growth hormone, or HGH, which is the body's most powerful natural revitalizer. One of the most important roles of HGH is to free up stored body fat, so you can burn it to produce energy. It also stimulates an increase in muscle tissue. HGH finds a way to reach all of your body's billions of fat cells. Attaching to specialized receptors on those cells, HGH triggers the signal that will induce the cells to release stored fat. The good news is that you can naturally stimulate the production of HGH at any age. Procrastination is a specific form of avoidance, with an "I'll do it later" attitude. In the moment, the child experiences a temporary relief from anxiety; however, in the long run, it will return and the child will be faced once again with either having to learn skills for managing stress or repeating patterns that generate stress. One of the most debilitating aspects of anxiety is its power to cause people to feel different, isolated, and cut off from the world. This feeling of alienation can come in many forms and tends to feed on itself. Often, feelings of being different and separate from others can lead to increased symptoms of anxiety and withdrawal. Left unaddressed, these are overpowering feelings that can lead to depression in a child with anxiety. Overlap between anxiety and depression is discussed later in article 14. Children who are anxious may shy away from contact with family as well. Although it is common for teens or children who are more solitary or introverted to spend time alone in their rooms, children feeling anxious may avoid family contact more often than not. Your child may try to opt out of family outings, especially when extended family is included. He may appear to be indifferent, "hang back," or be slow to warm when extended family or company is present. They may opt for solitary activity, even when the opportunity for more interesting group interaction is available. It is important to note that some children are naturally more introverted than others. This far-reaching idea gave rise to the slogan cells that fire together, wire together'. <br /><br /><a href=''>For</a>wiring together' to occur implies there must be structural changes or remodelling happening at the synapse. This means there must be molecules present, or arising as a result of activity, supporting or facilitating these changes. One of the key molecules is brain-derived neurotrophic factor, or BDNF, which might be thought of as a kind of a molecular fertiliser produced within the brain, because it supports structural remodelling and growth of synapses after learning.26 What we have learned recently is that a simple and straightforward way to raise BDNF levels in the brain, and particularly in the hippocampal formation, is aerobic exercise. Many experiments have demonstrated reliably that giving rats and mice the opportunity to exercise in running wheels increases significantly and reliably the level of BDNF in their brains.27 These animals are subsequently able to learn maze and other tasks more easily than their littermate controls who do not have access to exercise wheels. Moreover, if the increase in BDNF is prevented by specialised drugs that block this increase, the exercise-induced advantage in memory disappears. Many labs have now shown that aerobic exercise also increases the creation of new brain cells in the mature adult brain. It used to be thought that after birth no more brain cells were created. The scattered findings in the scientific literature in the decades preceding the 1990s, demonstrating that new brain cells can arise in the adult brain, were largely overlooked. Eventually, however, the weight of data became so great that the previous orthodoxy was overthrown. New brain cells are, however, only made in a few locations in the brain (a process known as `neurogenesis'). One especially important location is in a part of the hippocampal formation known as the dentate gyrus. Dr. Temoshok went on to work in the laboratory of Dr. Robert Gallo, the co-discoverer of HIV. He was running one of the most powerful immunology labs in the country. Normally a virologist such as Dr. Gallo would no sooner talk to a behaviorist than he would share the same toothbrush. So what is a clinical psychologist doing in one of the most successful virology labs in the country? They have discovered that the type C individual is more likely after exposure to HIV to progress to full-blown AIDS much more rapidly than the non-type C. It appears to be related to their CD4-positive lymphocytes, the T helper population which is largely responsible for coordinating the efforts of all of the other immune system cells.

What Dr. Temoshok discovered is that these CD4-positive cells have an altered chemokine receptor. Remember, that's the receptor, which responds to the chemical magnet drawing the cells to where they are needed. There are very pronounced and important biochemical changes that exist in these people that basically communicate that they have a dis-regulated immune system. It's a fact that women tend to gain excess body fat faster than men. 19 Not fair, of course, but this is where evolution has led us. The female body was engineered to ensure the optimal birth and well-being of human offspring. This meant women needed more body fat than men. As a result, men and women differ in how they produce energy and burn excess fat--processes driven in part by the so-called sex hormones. Both the male and female bodies contain the two primary sex hormones, estrogen and testosterone, but in varying percentages. Testosterone is a crucial fat-burning hormone. Human beings can't build any muscle tissue or muscle tone without it. In contrast, estrogen generally encourages the deposit of extra fat throughout the body. Estrogen-stimulated fat cells tend to more stubbornly hold on to their fat reserves. But there are good estrogens and bad estrogens. The bad estrogens--such as estradiol and 16-hydroxyl estrone--ramp up fat storage. The good estrogens, called 2-hydroxyl estrogens, encourage the release of stored body fat for burning during exercise. Children faced with anxiety may be highly sensitive, and at times overreact to challenges, disappointments, or feel isolated in their school environment. Making and keeping friends can be challenging. This is very difficult for parents to witness.

Some children may come home from school teary and overwhelmed by social demands they feel they cannot meet. Your child may make statements such as "no one likes me" or "everybody's mean to me." She may be afraid to try new things, like the monkey bars or the newest dance step, and may end up ostracized by her peer group, magnifying her sense of aloneness. Because peer relationships are so important, they will be addressed more fully later in this article in the section entitled "Friendship Fuss." Comparing yourself to others can reinforce the belief that you are not good enough or missing something. Parents can set the tone by being careful about comparing siblings or always measuring their child against his peers. Instead, direct your attention to your own child's milestones and hurdles with loving encouragement and praise. Children who feel anxious may view themselves as not like other children. The cycle of negative thinking that so often occurs magnifies fears and shortcomings. Because his experiences are perceived as more intense or overwhelming than those of his peers, he is left with a sense of "otherness" that may prevent him from identifying with and learning from his peers. Behavioral issues such as tearfulness or frequent meltdowns can alienate the child experiencing anxiety further from his peers. Unfortunately, it is not uncommon for children to avoid or reject kids who seem immature or have low self-esteem. Anxiety has a way of exaggerating what children don't like about themselves. When this occurs, achievements of others may be viewed as more important than is due, and the child may downplay his own accomplishments. Fear of failure may cause anxious children to give up before they have mastered a new skill. In their mind they think "why bother?", believing that they are unable to measure up to the expectations of their peer group. He may give up entirely on learning a new skill, like the child who becomes afraid of trying to ride a bike and who will not ride at all because his friends have already mastered the skill. A child experiencing anxiety may believe that others accomplish things effortlessly and give up on his task, believing he is a failure because the task isn't easy. If you believe this is true for your child, try modeling persistence and/or share a story of your own frustration with mastering a skill. Blocking the creation of new brain cells can cause disturbances in learning and memory. Moreover, animals in whom neurogenesis is blocked - for example, as a result of behavioural stress - show a depressive-like symptomatology: reduced levels of grooming and self-care, and reduced attempts to escape stressful situations (such as being placed in a small bath of water); they also show deficits in maze and reward learning and memory. Other work demonstrates that activity in the hippocampal formation arising from effortful learning or aerobic exercise is required for the incorporation of these new brain cells into the hippocampus itself.

BDNF provides a core, supporting molecular mechanism for learning and memory in the brain; BDNF is produced because of behaviour, including aerobic exercise, and in turn, the production of BDNF boosts learning and memory very effectively. BDNF also provides the brain with a remarkable degree of resilience, including resistance to ageing, and damage arising from trauma or infection. Demonstrating these changes in animals is relatively straightforward - in a post-mortem examination we are able to measure changes in an animal's brain after an experiment. For obvious reasons this is not the case in experiments with humans, although both direct and proxy measurements can still be taken from saliva and blood, as well as responses to a variety of cognitive and other tasks (using fMRI we can measure many changes in the brain's structure and function too). Everyone without exception needs to add regular activity to their life, whether they are overweight or not. Our bodies were not designed for a sedentary lifestyle and that's why we pay the price for it in terms of poor and declining health. People who are active and exercise regularly reduce their risk of developing and dying from some of the leading causes of illness in North America. Physical activity can improve your mental health as well as your physical health. Being physically active: A study done in October 2003 by the University of Southern California and the American Cancer Association and published in the journal Cancer showed that women who exercised had a 35% lower risk of developing breast cancer in situ than did inactive women. Although a sedentary life is not healthy, an overly aggressive exercise regime is not healthy either. A study that examined mortality rates over a 22 to 26 year period of 17,000 men who had attended Harvard University showed life expectancy was about two years longer for those that expended at least 2,000 calories per week via exercise compared to individuals who were sedentary. The study, done by Stanford University's Dr. Paffenbarger, showed that the death rate declined as the number of calories burned in activity increased - but only to a point. Death rates leveled off and then began to go up again in the men that expended more than 3,000 calories per week. According to this study, then the optimum amount of calories that should be burned during exercise per week is 2,000 calories. That translates to about 300 calories per day. It doesn't matter what exercise you do to burn these calories. The question now is how do you measure the type C individual? How do you determine that it exists? One of the characteristics of these people is they have a very high need for social desirability.
