What are the dangers of exercising on an empty stomach?

At present, with the continuous improvement of living standards, people's dietary standards are constantly improving, resulting in a lot of obesity. The slogan of exercise to lose weight is shouted every day. Some people even get up early every day to lose weight, especially when they are on an empty stomach, they start exercising. They think this is the best way to lose weight. Is it really so? Let me introduce to you the dangers 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.

When exercising, pay attention to:

1. Choose the right time

Many people like to exercise in the early morning, but it is not suitable for diabetic patients. Because the patient's blood sugar level is lowest when fasting, exercising at this time can easily cause a hypoglycemic reaction. Therefore, diabetics should schedule their exercise time one hour after a meal. To prevent hypoglycemia, carry some biscuits, candies, chocolates, or sugary drinks and water with you.

2. Exercise should not be too intense

You should do moderate-intensity, slow-paced aerobic exercise, such as walking, jogging, gymnastics, Tai Chi, Tai Chi sword, dancing, and yangko dancing.

3. Prevent foot injuries

When exercising, you need to wear elastic sports shoes with slightly thick soles and uppers that are neither soft nor hard, and cotton socks with good water absorption. Always check your shoes for foreign objects and clean them out in time to prevent foot injuries.

4. It is best to test your blood sugar before exercise

You should not exercise when your blood sugar level is too high (greater than 16 mmol/L) or too low (less than 6 mmol/L). People with cardiovascular disease and kidney disease should limit their activity.

5. Check your heart rate at any time during exercise

The best heart rate during exercise should be 170-age. Avoid exercising blindly without any consideration.

After reading the above introduction, do you feel that it is inappropriate for you to exercise on an empty stomach in the morning? It is recommended that you should not do any fitness activities on an empty stomach in the morning, as this will cause great harm to your body. It is best to eat something first and wait half an hour before exercising, which is better for your body. Never do anything that is harmful to your body!
