【文章內(nèi)容簡(jiǎn)介】 th experts say that since the year 1900, extremely hot weather has killed more people in the United States than any other natural event. One year, the unusually hot summer of 1980heat caused about 1,700 deaths in the United States. In 1995, more than 600 people died in a similar heat wave in one city— Chicago. To measure extreme heat, government weather experts have developed the Mean Heat Index. It measures the average of how hot it is felt all day on an extremely hot day. Experts say it is the total heat of a hot day or several hot days that can affect health. Several hot days are considered a heat wave. Experts say heat waves often bee deadly when the nighttime temperature does not drop much from the highest daytime temperature. The most mon medical problem caused by hot weather is heat stress. Usually, it also is the least severe. For most people, the only result of heat stress is muscle pain. The pain is a warning that the body is being too hot. Doctors say drinking water will help the pain disappear after the body again has the right amounts of water and salt. For some people, however, the result is much more serious. For example, doctors say some people face a greatly increased danger from heat stress. These people have a weak or damaged heart, high blood pressure, or other problems of the blood system. Severe heat can help cause a heart attack or stroke. Health experts say this is the most mon cause of death linked to hot weather. 16. How many people died from heat in Chicago in 1995? A.

After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day. There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other. Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move more quickly （ Although your eyelids are closed） . This stage of sleep is called REM, which stands for rapid eye movement. If you have trouble falling asleep, some people remend breathing very deeply.
