Stress and energy consumption
in modern society, stress is a daily experience. Interaction between stress and the state of energy expenditure in the body is not a big problem. The real problem is not to happen curb the excessive reaction in eating behavior to cope with stress, and higher than a level more is knowing how to avoid the consequences of stress caused to health. Stress is a word used refers to a strain physically or mentally. It can be understood simply as stress occurs when the pressure that you have to suffer beyond your normal response (S.Palmer, 1999). Stress occurs when pressure that you may incur excess Resilience of your normal Normally, the body respond to this state by an "acceleration" of physiological processes, especially in the nervous system, cardiovascular system, respiratory system and internal systems weather. But there are also cases where the body showed "inert" or "down country"; or meet confusion between the two extremes mentioned above. The overload caused by stress on the body, particularly prolonged stress, can give rise to a number of physical symptoms and behavior - psychology. And so, depending on the response of the body will have a different energy consumption. Energy (usually measured in calories) provides the body's activities mainly from feed, and a small part is the self-sufficiency of our own bodies. Nearly two-thirds of total energy consumed in the body is to serve basic metabolism - the process of metabolism essential to sustain life in the least energy consumption. More than a third of the remaining is for the movement, to digest food for energy, and compensate for the needs arising as the environmental temperature changes, for example. In normal conditions, the body can self-adjust to maintain the balance of supply and demand of energy. If energy "inputs" too much to the needs of the body, it will be stored as fat in fat cells. This fat will be mobilized to generate energy whenever the body needs more "fuel" than the supply from outside is insufficient to meet. In the stress condition occurs frequently, especially physical stress , energy consumption may increase many times the normal needs of a person of the same age and same gender. That is the case of sports athletes, of those working in the harsh environment (too hot, too cold, underwater divers). These objects need to capture a greater amount of food to provide fuel for the body. However, the transient physical stress, the expression of energy consumption over the unpredictable. Usually, to deal with stress, the body needs more energy to "fight or run". The level of instantaneous energy consumption can increase suddenly, but its impact on the caloric intake is not discernible. In that situation, people need to eat or drink more to compensate for the energy consumed, but also to people who are not eating. In fact, the behavior of every person in this situation is strongly affected strong by their psychological state, but not necessarily by the "demands" of the body material. Because, in our body always available energy reserves to cope ahead. In the psychological stress as well, although the psychological stress often prolonged and difficult to get to know better. Several studies in mice showed that the excited state of prolonged stress contributes to increased consumption of foods rich in fat and carbohydrate and can increase the risk of obesity. On humans, the psychological symptoms and different behavior in terms of stress can cause the body to consume less energy or more, depending on the prominent symptoms. Stress can lead to long-term questions serious health problems. It disrupts the normal functioning of most organ systems in the body. It can increase blood pressure, inhibit the immune system, increase the risk of heart disease and stroke, contribute to infertility, and makes the aging process happens faster. Prolonged stress affects the brain, it may make people more likely to fall prey to anxiety, depression. The body can not differentiate the nature of the physical or psychological stress come from outside. When we fall in tension due to busy schedules, by arguing with friends and colleagues, due to congestion, or due to a large debt payment, the body reacts as if we face with a situation of life and death ...
