It converts protein into glycogen and begins the process of storing fat. Some of the studies suggest that higher intensity effort has a more dramatic effect on symptoms.

SPARK Welcoi first thing he did was separate Jessie and her twin—and all ofthe you know how to handle i other inseparable cliques. As the course progresses.

Since exercise influences metabolism, it serves as a powerful way to influence synaptic function, and thus the way we think and feel. Throughout the body, exercise increases blood flow and the availability of glucose, the essentials for cell life. In addition to raising the fight-or-flight threshold, it kick-starts the cellular recovery process. Exercise increases the efficiency of intercellular energy production, allowing neurons to meet fuel demands without increasing toxic oxidative stress.

We do get waste buildup, but we also get the enzymes that chew it up, not to mention a janitorial service that disposes of broken bits of DNA and other by-products of normal cellular use and aging — both of which are thought to help prevent the onset of cancer and neurodegeneration. On a mechanical level, exercise relaxes the resting tension of muscle spindles, which breaks the stress-feedback loop to the brain.

Over time, regular exercise also increases the efficiency of the cardiovascular system, lowering blood pressure. With exercise, you gain a sense of mastery and self-confidence.

You learn to trust that you can deal with it. More and more companies are encouraging their employees to take advantage of in-house gyms or health club memberships, and some health insurance companies reimburse clients for club fees. Their generosity is informed by studies showing that exercise reduces stress and makes for more productive employees. Just keep in mind that the more stress you have, the more your body needs to move to keep your brain running smoothly.

And someone with generalised anxiety disorder tends to respond to normal situations as if they were threatening. When we are in this state, we begin to anticipate that everything is going to be a disaster, and so we try to avoid everything, and our world begins to shrink. By using exercise to combat the symptoms of anxiety, you can treat the state, and as your level of fitness improves, you chip away at the trait.

The fact that aerobic exercise works immediately to fend off the state of anxiety has been well established for many, many years. In the body, physical activity lowers the resting tension of the muscles and thus interrupts the anxiety feedback loop to the brain. If the body is calm, the brain is less prone to worry. Exercise also produces calming chemical changes. As for the trait, the majority of studies show that aerobic exercise significantly alleviates symptoms of any anxiety disorder.

But exercise also helps the average person reduce normal feelings of anxiousness. The elegance of exercise as a way to deal with anxiety, in everyday life and in the form of a disorder, is that it works on both the body and the brain. The problem with the strictly biological interpretation of psychology is that we sometimes lose sight of the fact that the mind, brain, and body all influence one another.

The stability of the routine alone can dramatically improve your mood. Aside from elevating endorphins, exercise regulates all of the neurotransmitters targeted by antidepressants. For starters, exercise immediately elevates levels of norepinephrine, in certain areas of the brain. It wakes up the brain and gets it going and improves self-esteem, which is one component of depression.

Exercise also boosts dopamine, which improves mood and feelings of wellness and jump-starts the attention system. Dopamine is all about motivation and attention. It also helps stave off stress by counteracting cortisol, and it primes the cellular connections in the cortex and hippocampus that are important for learning.

The closer we get to the cause of depression, the more complex it appears. When we began, everyone was fairly certain that the problem was an imbalance of neurotransmitters at the synapses. Ironically, this is precisely why exercise has yet to be embraced as a medical treatment. It adjusts all of them, to levels that, we can only presume, have been optimally programmed by evolution. But the evidence is there. Yes, exercise is an antidepressant. But it is also much more. Asking someone to join you in exercise and putting yourself in a new setting will give those newly hatched neurons a powerful reason for being; new connections need to be formed to represent the sensory stimulation.

Breaking out of the emptiness that the brain has been locked into provides a sense of purpose and self-worth that evokes a positive future. Once you develop the positive feeling, you need to devote it to something. Then you get the bottom-up motivation and physical boost combined with the top-down reevaluation of yourself. Start slowly and build on it. At its core, depression is defined by an absence of moving toward anything, and exercise is the way to divert those negative signals and trick the brain into coming out of hibernation.

As a treatment, exercise works from the top down in the brain, forcing addicts to adapt to a new stimulus and thereby allowing them to learn and appreciate alternative and healthy scenarios.

The inoculation works from the bottom up, physically blunting the urge to act by engaging the more primitive elements of the brain. Exercise builds synaptic detours around the well-worn connections automatically looking for the next fix.

The biology of stress ties in with addiction in that withdrawal puts the body in survival mode. The intense unpleasantness of withdrawal lasts for only a few days, but your system remains sensitive for much longer. The most effective solution to a stressful situation — and the only one an addict knows — is the drug. But exercise is another solution. In smokers, just five minutes of intense exercise can be beneficial. Nicotine is an oddball among addictive substances as it works as a stimulant and a relaxant at the same time.

Exercise can fend off cravings for fifty minutes and double or triple the interval to the next cigarette. If exercise acts like certain drugs in the brain, then you might wonder whether it can also be addicting. The danger of getting addicted to exercise applies to a very small segment of the population, most notably girls with anorexia or anyone with a body dysmorphic syndrome, a mental disorder defined by a preoccupation with a perceived deficit in appearance.

They eat less and less, and when they exercise they become light-headed and exhilarated, the high only reinforcing the cycle. In this respect, dealing with addiction is similar to battling feelings of anxiety and depression: Once the addiction or the negative emotions are gone, the void needs to be filled with some positive behaviour for the change to take root. There can hardly be a better option than physical exercise. The fact that exercise counteracts anxiety and depression directly can have a huge impact on any form of addiction, as both of these mood states undermine treatment.

A recovering addict who is feeling anxious or hopeless is much more likely to slip in her determination and ability to quit. People are more impulsive when they feel lousy.

Both strength training and aerobic exercise decrease symptoms of depression in recovering alcoholics and smokers who have quit. And the more fit you are, the more resilient you are. How much exercise you need depends, of course, on how severe the habit is. But I would say thirty minutes of vigorous aerobic exercise five days a week is the bare minimum if you want to root out an addiction.

If you have an addiction to food, try a quick walk around the block or a few minutes with a jump rope or even a set of thirty jumping jacks — anything to snap your mind out of the cycle of thinking about the reward. Try it. Hormones have a powerful influence on how our brains develop as well as on our feelings and behaviours and personality traits throughout life. After adolescence, hormone levels remain fairly steady in men, but in women, they fluctuate like clockwork.

The constant shifting affects every woman differently, and this must be factored in to any discussion of brain health. Exercise is particularly important for women because it tones down the negative consequences of hormonal changes that some experience, and for others, it enhances the positive. Overall, exercise balances the system, on a monthly basis as well as during each stage of life, including pregnancy and menopause. It can give you a handle on a part of life that feels beyond your control.

And with a lifestyle change, medication may not be necessary. One explanation, certainly, is that physical activity increases levels of tryptophan in the bloodstream and thus concentrations of serotonin in the brain. It also balances dopamine, norepinephrine, and synaptic mediators such as BDNF. By stabilising such a broad number of variables, exercise helps to tone down the ripple effects of shifting hormones. For younger women with PMS, I would suggest five days a week of aerobic exercise at the same level.

But it might be a good idea to mix in more intense bursts like sprinting on two of those days. Some of the studies suggest that higher intensity effort has a more dramatic effect on symptoms. The mental and physical diseases we face in old age are tied together through the cardiovascular system and metabolic system. A failure of these underlying connections explains why people who are obese are twice as likely to suffer from dementia etc.

Statistically, having diabetes gives you a 65 percent higher risk of developing dementia, and high cholesterol increases the risk 43 percent. Yet, about a third of the population over sixty-five reports that they engage in no leisure-time activity. Getting older is unavoidable, but falling apart is not. People who stay involved and active as they age can slow down the degeneration. Researchers found that those who exercised maintained nearly the same level of blood flow in the brain after four years.

Exercise is one of the few ways to counter the process of aging. This is because it slows down the natural decline of the stress threshold. It improves their ability to cope with more severe stress. It increases blood volume, regulates fuel, and encourages neuronal activity and neurogenesis. Because the aging brain is more vulnerable to damage, anything you do to strengthen it has a pronounced effect.

It shows up in the little things first. Exercise not only keeps the brain from rotting, but it also reverses the cell deterioration associated with aging. You might be able to recruit other areas of the cortex to do the task in a different way. One way to think about the increased volume is that it might turn back the clock in terms of how well the circuits function to do different things.

When people come to recognise how their lifestyle can improve their health span — living better, not simply longer — they will, at the very least, be more inclined to stay active. For anyone over sixty, I recommend exercising almost every day.

In retirement, why not? Six days a week would be ideal, but make it fun rather than work. Your overall strategy should include four areas: You should consult with a doctor or trainer who knows your history. How much exercise they should you do for the brain? The best advice is to get fit and then continue challenging yourselves. The prescription for how to do that will vary from person to person. But, the research consistently shows that the more fit you are, the more resilient your brain becomes.

And the better it functions both cognitively and psychologically. If you get your body in shape, your mind will follow. In fact, many of the most convincing studies use walking as the mode of exercise. Any level of activity will help, certainly. Body and brain are connected. Why not take care of both? Walk or jog every day, run a couple of times a week, and then go for the kill every now and then by sprinting.

Walking, or low-intensity exercise, is exercising at 55 to 65 percent of your maximum heart rate. Moderate intensity falls in the range of 65 to 75 percent, while high intensity is 75 to 90 percent. The upper end of high-intensity exercise is sometimes painful but always powerful territory that has gained a lot of scientific interest recently.
