Why do people exercise in the 21st century? Studies show that people who don’t exercise are more likely to get diseases than people who exercise. Since the 1970s, the number of fast food restaurants has more than doubled. And more than 23 million Americans, including 6.5 million children, live in food deserts-areas that are more than a mile away from a supermarket. In addition, 25 percent of adults who aren’t active at all and this leads to obesity. “Modern people also consume a lot more calories, 2,178 a day now as opposed to 1,818 then”. This could be down to eating more junk food, the study suggested, as people in 1953 were more likely to cook meals from scratch with a mixture of ingredients. But now people can burn calories faster than before because they know how much calories does the food contain and also the modern exercises helped them to burn calories faster. There are several effects of people exercising in the 21st century.
The first result is that it will keep you healthy. Americans are eating enormous amounts of fast foods these days, so heart diseases are becoming more and more common. One out of every four Americans are suffering from some form of heart diseases, which results in more than forty-five percent of deaths annually. The main cause of this condition is obesity. The more body fat that you have, the greater your risk for heart disease. However, this condition can easily be prevented or controlled by exercising. Exercising makes the heart muscles stronger. When your heart muscle is strong it can do the same amount of work at a lower heart rate, so the heart doesn't have to work as hard. In today's society people are less concerned with the food that they eat and the condition that their body is in, so many serious illnesses are becoming quite common. Exercising not only helps prevent heart diseases, but it also helps prevent strokes, and diabetes, and even certain types of cancer. According to Dr. Edward H. Stanley, “Those who think they have not time for bodily exercise will sooner or later have to find time for illness”. So people need to start exercising before they get ill.
Another positive result due to a person exercising is improving self-esteem and confidence. Most people think of exercising as only being a physical activity, but it's also a mental activity. There have been studies that show evidence that people who exercise have higher self esteem and confidence. It also showed that active people are less likely to have depression and anxiety. Exercising gives people energy, which helps people have positive outlooks on life and it helps relieves tension and stress. When you exercise your body releases endorphins, which are chemicals that create a happy feeling in brain. Plus, when you're exercising you're bringing more oxygen into you lungs and your brain appreciates the extra air. Exercising also helps improve you brain function and your memory.
The final result that can happen to a person that he will have a good time exercising. Most people think that exercising takes up a lot of time and it requires too much work. When people actually take the time to try exercising they realize it's an enjoyable experience. It doesn't matter how you…
