Many people do not realize, and often underestimate, the importance of good health. Health, as they say, is wealth. Good health is necessary to carry out daily tasks. When discussing healthy, many people would consider the condition of their bodies and forget about the condition of their minds. However, health is not only about alleviating and being free from physical aspects of health. It also means being healthy in mind too. An unhealthy mind results in an unhealthy body. Good mental health helps you to make the most of life and enjoy it. Good mental health offers you a feeling of well-being and the inner strength needed in times of trouble or unrest. Everyone knows how to care for their bodies. This is done almost every day by the majority of people. Exercise and eating the proper foods are the best ways of keeping the body healthy. But, how does one keep the mind healthy? A healthy mind requires a lot of work, as well as, a combination of the right foods and exercise. Most often, the food consumed has a pivotal effect on the body, as well as, the mind. A healthydiet consists of the right food groups with right number of calories. It does not contain an excess of sugar, salt, fat and alcohol. Selecting the right foods that provide energy helps the body to be healthy. This also helps the mind. An energized person is a happy person. Happiness is a state of mind. Without proper energy, a person can become angry, tired and sad. These are not good for the mind. Exercise is extremely important to staying healthy both in body and mind. Being active can help a person continue to do things they enjoy and be independent as they age. Long term physical activity increases the benefits of long-term health. This is the reason many health experts advise individuals to be as active as possible and to set aside at least three days a week for some form of activity that keeps the heart beating at a steady pace. Physical exercise also has many mental benefits. For example, a person diagnosed with depression or anxiety is most often asked to conduct some form of physical activity apart from taking medication. This is because, the body produces hormones known as endorphins which improve mood and relieve stress. Depression can be alleviated by improving mood and anxiety can be relieved by reducing stress. Another method of keeping the mind healthy is to exercise it as often as possible. Just as physical exercise is good for the body, so is mental exercise for the mind. There are numerous ways to ensure a healthy mind through activity. For example, doing cross word puzzles, calculating sums in the head, learning a new word every day etc. can be extremely beneficial for the mind. This form of mental exercise is not only for the elderly. It is for all individuals who wish to keep their minds healthy. Very few individuals take the time to care for themselves with busy lifestyles and schedules. However, taking care of yourself is the best way of ensuring you live a long healthy life, not only physically, but also mentally. The human heart can beat only 220 times per minute, and that maximum can only be attained by a young child. The maximum number of times your heart can beat declines with age for reasons that are not clearly understood. The decrease in the number of beats per minute with age has nothing to do with stamina or fitness. Marathon runners often peak in their late 30s despite their hearts beating less times per minute than a 10-year-old or a 20-year-old. If you want to determine your maximum heart rate, or the maximum number of times your heart can beat per minute, subtract your age from 220. Say, for example, you are 40 years old. Subtracting 40 from 220 leaves 180, the maximum number of heart beats per minute for a 40-year-old. Your maximum heart rate helps you determine what sort of a workout is best for you from an aerobic standpoint. If people were to push their heart rate to the maximum for their age, they would quickly tire and have to stop and rest. Many believe that the ideal maximum heart rate for a workout should be about 80 percent of the maximum for your age. In other words, multiply your maximum heart rate by .80 and you’ll get the ideal heart rate for a workout, also known as your target maximum heart rate. So for the aforementioned 40-year-old, his target maximum heart rate would be 144 beats per minute, or 180 x .80. If this 40-year-old were doing a serious workout — such as running at a good pace — he might want to hover around 144 beats per minute for much of the workout and slowing down or speeding up as needed. However, many people prefer workouts that are not this intense but still effective. They might want to target 60-70 percent of the maximum beats for their age as an ideal number. Still others like to vary their workout intensity from day to day or even within the same workout, such as walking a bit, then jogging a bit, then walking and so on. Whatever works for you is best. However, workouts less than 60 percent of the maximum for your age may not be intense enough to promote good cardiovascular fitness. What Your Heart Rate Reveals About You Any of you who take up regular aerobic exercise will notice that your resting pulse rate will drop over time — meaning that your heart does not have to work as hard and beat as many times per minute to get nutrients and oxygen distributed to all of your body. If you have ever had a cardiac stress test done, this test is controlled by your heart rate. You are initially at rest on a treadmill with an apparatus hooked up to you, which monitors your heart rate and provides EKG readings, among other things. The treadmill is gradually increased in both speed and incline. This continues until you reach a heart rate that’s 80 percent of the maximum for someone of your age. Then the test stops. People who are sedentary and unfit might get to their maximum in less than 5 minutes of very slow walking. A very fit runner might be on the treadmill for 30 minutes, and at the end of the test the treadmill forces the person to run fast and the incline is high. So the stress test determines how fit you are in addition to abnormalities in your heart. How Many Beats Do I Have Left, Doc? There can be a dramatic difference in the number of times a person’s heart beats if they are fit and unfit. Say, for example, that a fit person’s heart beats 55 times per minute and an unfit person’s heart beats 85 times per minute, a difference of 30 beats per minute. That difference amounts to 1,800 heartbeats per hour, 43,200 beats per day, and more than 15 million heartbeats per year. Over 20 years, the fit person’s heart will save approximately 315 million heartbeats over the unfit person. That’s about 11 year’s worth of heartbeats! It has never been proven that the heart has only so many beats in it because the research is impossible to do, but this idea makes sense to many. It would certainly be nice to have millions of extra heartbeats in your savings account if there is any truth to the idea. It HAS been shown that people who get regular aerobic exercise live longer than those who don’t exercise, and have other benefits such as: less cardiovascular disease, less cancer, less hypertension, less diabetes, weight loss, better brain functioning, and still many more. |
