實(shí)用英語口語(高等級) 25.Symptoms of stress
PROFESSOR:令人驚奇的是，當(dāng)我們受到壓力時(shí)，我們的身體會做出和幾千年前我們的祖先遇到危險(xiǎn)時(shí)一樣的反應(yīng)：“打還是跑”。 This is when our brain releases chemicals that give us extra strength and speed, so that, in any dangerous situation, we can either stay and fight, or run away. This is called a 'stress response', and it can be pretty useful. It doesn't just help you escape from dangerous situations, it also comes in handy if you're competing in a sporting event, have an important deadline to meet at work, or are taking an exam. However, the problem is, when we find ourselves in a situation that causes us stress on a regular basis for example worrying about our job, money, family or relationship our brain still produces these 'Fight or Flight' chemicals.
PROFESSOR:Our heart beats faster, our blood flows more quickly, we feel hot, we sweat and, to save energy, we even stop digesting our food. This, of course, can be bad for our health. In fact, if we suffer from this kind of 'low level' stress over a long period of time, it can make us seriously ill. So, how can you tell if you or someone you know is suffering from stress? Well, there are a number of physical and behavioral symptoms to look out for.
PROFESSOR:Physical symptoms of stress can include high blood pressure, shortness of breath, chest pains, headaches, muscle pain, insomnia, hair loss and allergies. Behavioral symptoms can vary, but any change in someone's normal personality, such as greater anxiety, sudden mood swings or an unusually negative outlook on life, can be signs that the person is stressed. Stress can also make existing behavioral problems, like alcohol or substance abuse, worse. Being stressed also means you don't look after yourself. If you're stressed out, it's important to make sure you get enough sleep, take regular breaks, eat and drink healthily and get regular exercise.
PROFESSOR:Conversely, falling into a cycle of negative lifestyle habits just makes things worse. Despite an increasing number of scientific studies, the link between stress and serious illness is still a controversial one. Not all scientists agree that stress, in itself, causes illness or disease. However, stress has been linked to high cholesterol levels in the blood, gastrointestinal problems and even diabetes. Stress may also put people at greater risk of heart attacks and strokes.
PROFESSOR:But don't start getting too stressed out about stress! The most important thing to remember is this: if you live a well balanced life, and that means work life and home life, you can manage your stress levels independently, without any cause for concern.
