But first, running in the morning is not good for your health.

Running on an empty stomach is very harmful to human body.

Normal exercise needs energy to maintain, and energy mainly comes from food. If you run on an empty stomach, you can only maintain your energy by burning fat.

Fasting exercise leads to a significant increase in free fatty acids in human blood. If there are too many free fatty acids, there will be "poisons" that damage the myocardium. This "poison" often leads to abnormal heart rhythm and even sudden death.

The harm of morning running

Running in the morning increases the possibility of vascular thrombosis, which is easy to cause vascular embolism, because the blood cohesion is improved by 6%. On the other hand, running at night will reduce the number of platelets by 20%, greatly reducing the risk of vascular embolism.

In addition, the high blood pressure, heart rate and acceleration during morning running are easy to cause overload and affect the exercise effect and health. At night, the sensitivity and adaptability of physical strength and limb reaction reach the peak, the heartbeat frequency is the most stable or low, and the heartbeat and blood pressure caused by exercise rise slowly, which is beneficial to health. Running late can also promote better sleep.

Sports medicine proves that when you wake up in the morning, the operation of human organs is still at a low level. At this time, exercise is more dangerous for people with fragile cardiovascular function. The activity ability of human body is fully developed at night. Running at this time makes it easier for the body to adapt to the rhythm of exercise.

From the external environment, the latest research shows that the carbon dioxide index in the air is the highest in the morning, and the dust suspended in the air the day before has not completely disappeared. At this time, exercise is far less good than the environment at night.

After running at 6 o'clock in the morning, many people may not have eaten yet, so they searched for "running on an empty stomach":

Running on an empty stomach will increase the burden on the heart and liver, and it is also prone to arrhythmia and even sudden death.

Don't exercise for half an hour after meals, and don't do strenuous exercise for an hour.
