How about running on an empty stomach in winter morning?

One: It is not good to run on an empty stomach in winter morning exercise.

Two: In the morning, the abdomen is empty, and exercise needs to consume energy. If it is not supplemented in time, the free fatty acids in the blood that can lead to arrhythmia or even sudden death may increase significantly. Therefore, dizziness, palpitation and leg weakness may be mild, but they may also be unstable, sudden fall or even sudden death. Therefore, a small amount of soft food, such as hot soybean milk, porridge, oatmeal, lotus root starch, snacks, boiled eggs and so on. You should eat it before morning exercise. It's not big, but it's better to be nutritious. As we all know, you can't exercise immediately after eating. Morning exercises in winter can neither be empty nor full.

Third, a cup of warm boiled water (150 ~ 200ml) should be added in the morning, which can reduce blood viscosity, promote diuresis and detoxification, prevent constipation and promote systemic blood circulation. Otherwise, cardiovascular and cerebrovascular diseases, especially acute myocardial infarction, may occur during morning exercise due to the relative lack of blood volume in the body and the increase of blood pressure.
