Can I exercise on an empty stomach?

Many times, we often see a person doing some exercise when he is healthy, running is more common, but they usually run on an empty stomach. Is such exercise really good for our body? What are the dangers and disadvantages of such an approach? If Chen Li has the habit, how should she choose the time for morning exercise? What kind of exercise is both safe and healthy?

There are some things to pay attention to when doing exercise. Is it better to exercise on an empty stomach or on a full stomach? There is some controversy on this issue. Experts will introduce to you the harms of exercising on an empty stomach.

People all know that exercising on a full stomach is not good, but they disagree with exercising on an empty stomach. They believe that the gastrointestinal tract does not require much blood when exercising on an empty stomach, and the gastrointestinal tract will not conflict with the limbs for blood. In fact, this is a wrong understanding. Exercising on an empty stomach is more dangerous.

The main source of energy for the human body is carbohydrates (sugar) in the diet. After a night's rest, the body's energy is almost consumed, and the blood sugar concentration in the body is low. At this time, if we exercise without eating anything, we will inevitably consume a lot of energy, and our blood sugar concentration will be even lower. Blood sugar is the direct energy source for the brain. If the blood sugar concentration is too low, the brain will feel tired due to lack of power, and people will feel dizzy and weak. Some people may even turn pale and sweat. If it continues, the patient will become unconscious or even fall into a coma.

Another disadvantage of exercising on an empty stomach is that when a person is on an empty stomach, the main source of energy is converted from body fat. At this time, the free fatty acids in the blood will increase significantly. Fatty acids are the energy source for muscle activity such as the myocardium, but when the amount is too much, it can become a poison to the myocardium, causing various arrhythmias and even leading to sudden death.

If we have the habit of morning exercises, we'd better drink a cup of boiled water half an hour before going out for morning exercises. This is good for our body when going out for exercise. However, do not exercise for too long or too hard. Just exercise in moderation.
