Research shows that walking speed can really predict the length of life, especially for middle-aged and elderly people. Normal people walk at a speed of about 0.9 meters per second. If it is lower than 0.6 meters per second, the probability of death will increase. If you walk 0.8 meters per second, it proves that your life expectancy is above average. Generally speaking, people who walk fast tend to live longer. Because people move most muscles when walking, the bones and nervous system of the whole body are moving, and the blood flows smoothly, which requires enough vital capacity. So the speed at which we walk is actually related to our physical fitness. Especially for middle-aged and elderly people, it is more suitable to judge the length of life by walking speed!
So, if we often take a walk, can we really stay healthy? In fact, it is almost enough for normal people to keep more than 4000 steps of exercise every day. If we exceed the quota, our knees may be damaged and our bodies cannot exceed the limit we can bear. If your knee is under great pressure, it will hurt your knee. More than 4,000 steps is a very reasonable amount of exercise. Middle-aged and elderly people, over 60 years old, should keep exercising for no more than 40 minutes every day, and the number of walking steps should not be less than 4,000, but not more than 10000.
If you want to stay healthy and live a long life, you should pay attention to your diet besides exercise. You must have a balanced nutrition and an optimistic and positive attitude, which is the most important thing! The above remarks are for your reference only!
