Advantages and Disadvantages of Stress
Stress can lead to the top and take full advantage of its performance and welfare. In excess, however, can weaken the heart, memory and mental clarity, and increase your risk of chronic diseases.
So how can extract its benefits and avoid the harmful effects?
According to researchers and psychologists, learning to identify and monitor stress reactions can live healthier and improve performance on cognitive tests, work and athletic activities.
The body has a standard reaction when faced with a task where performance really matters for the welfare or reach a goal: the sympathetic nervous system and the hypothalamus, pituitary and adrenal glands pump out stress hormones adrenaline and cortisol blood flow. Heartbeat and respiration are accelerated and the muscles tense.
Relaxation techniques, deep breathing and thinking tasks with positive results help to give a twist beneficial to stress.
What happens next is what separates good stress from bad stress. People experiencing stress pumping feels beneficial. The blood vessels dilate, increasing blood flow to help the brain, muscles and limbs to meet the challenge they face, like the effects of aerobic exercise, says Wendy Mendes, an associate professor in the department of psychiatry at the University of California, San Francisco.
The body tends to respond differently to stress harmful. The blood vessels contract and may experience a little dizziness as the blood pressure rises, says Christopher Edwards, program manager control of chronic pain Medical Center Duke University. Symptoms are similar to those experienced during a fit of rage. Can you speak louder or experience lapses of judgment or logic, he says. Hands and feet are cold as the blood flows to the core of the body. Research shows that the heart usually beats erratically, like a seismograph during an earthquake.
People under stress lose the ability harmful to reconnect the parasympathetic nervous system, responsible for daily body’s natural functions such as digestion and sleep. Although chronic stress tolerance varies from person to person, research shows that significantly increases the risk of insomnia, chronic illness and death at an early age.
Carl Weissensee, dedicated to building luxury homes, used to be “addicted to stress,” yet thousands of details and multiple risks for nearly all hours of the day, affecting the rest of his life. A heart attack, followed by a cardiac arrhythmia, forced to find a balance between good stress and bad. Today using relaxation techniques, deep breathing and lying and imagining stressful tasks with positive end. Weissensee learned to recognize their concerns instead of recycling in your mind, tell yourself that “everything will end well,” he says. The builder has learned to stabilize his heart condition without large doses of medicine. “My goal is to worry just enough to do my job,” he adds.
That attitude tends to produce good stress, according to research by Mendes and others. In a study of 50 college students, some were led to believe that feeling or emotion nerves before a test could improve performance. Another group not. When asked all students to give a speech about themselves, those who received the warning showed a healthier physiological response, which meant a smaller increase in blood pressure than the other group.
People react differently to daily stress. Instruments that measure physiological functions can detect jumps in heart rate. Manual thermometers can be used to distinguish when the temperature of the hands falls below 35 degrees, says Kenneth Pelletier, clinical professor of medicine at the University of Arizona.
For most people, stay calm requires new skills. With practice, however, learn to relax completely in seconds, says Pelletier. They also help positive thoughts about what causes us stress, deep abdominal breathing, meditation and regulation of mental and physical states.
