mindmap root((HYPER)) hyperactive Excessively active.
🌱Stephen King's hyperactive imagination has produced dozens of fantastical stories, not to mention countless nightmares in his readers. 🌳For doctors and psychologists, hyperactive describes a condition with unpleasant consequences. Hyperactive children usually have a very short attention span and can't sit still, and hyperactivity can lead to difficulty in learning or just get them in trouble for disturbing their classes. But not every high-spirited child is hyperactive. Having a high energy level is pretty normal for children, and some parents think that prescribing drugs for hyperactivity is mostly just good for the drug companies. hyperbole Extreme exaggeration.
🌱The food at Chez Pierre was good, but it couldn't live up to the hyperbole of the restaurant critics. 🌳Advertisers and sports commentators make their living by their skillful use of hyperbole. Presenting each year's Superbowl as "the greatest contest in the history of sports" certainly qualifies as hyperbole, especially since the final scores are usually so lopsided. Equally hyperbolic are advertisers' claims that this year's new car model is "the revolutionary vehicle you've been waiting for" when it's barely different from last year's—which of course was once described in the same glowing terms. Politicians love hyperbole too; some of them seem convinced that calling a new bill "the worst bill ever passed by Congress" or comparing the president to Hitler is a great way to win votes. hypertension High blood pressure.
🌱Pregnancy is often accompanied by mild hypertension that doesn't threaten the mother's life. 🌳You might have thought that hypertension was what a movie audience feels near the climax of a thriller, but you would have been wrong. High blood pressure—that is high pressure against the walls of your veins and arteries caused by blood flow—often occurs when the arteries or veins become blocked or narrowed, making the heart work harder to pump blood. But many cases seem to be the result of smoking or taking in too much salt, and many are genetically caused. Hypertension is serious, since it can lead to heart attacks and strokes. Though it often produces no warning symptoms, your blood pressure can be checked quickly and easily by a nurse. If it's high, it can usually be controlled by stopping smoking, losing weight, lowering your salt intake, and exercising—and if all else fails, by medication. hyperventilate To breathe rapidly and deeply.
🌱They laughed so hard they began to hyperventilate and feel giddy. 🌳Hyperventilating can be a response to fear and anxiety. A test pilot who panics and hyperventilates faces a dangerous situation. When the level of carbon dioxide in your blood goes down and the oxygen level goes up, blood vessels constrict because of the chemical changes and the body can't get enough oxygen （even though it's there in the blood）, and the pilot can become lightheaded and may even faint. To guard against this, pilots are taught to control their breathing. On the ground, the usual remedy for hyperventilation is breathing into a paper bag, which raises the level of carbon dioxide and restores normal breathing.
