Introduction
Whether or not you can run on an empty stomach in the morning depends on individual circumstances. It is not recommended for individuals with poor physical health, older adults, or those suffering from conditions such as hypertension or diabetes, as fasting exercise may trigger hypoglycemia, arrhythmia, or even sudden death. However, young people or individuals with good physical fitness who do not have underlying medical conditions may engage in moderate morning runs on an empty stomach.
Whether or not you can run on an empty stomach in the morning depends on individual circumstances.
1. Not recommended
Individuals with poor physical fitness, elderly people, or those who have chronic conditions such as hypertension or diabetes should avoid running on an empty stomach in the morning. Running consumes significant energy, and for diabetic patients—especially those undergoing insulin therapy—running before breakfast typically fails to provide sufficient energy for exercise. This can cause a rapid drop in blood glucose levels, increasing the risk of hypoglycemia, fainting, or falls. Additionally, prolonged or intense running on an empty stomach in the morning may increase strain on the liver and heart, potentially triggering arrhythmias or even sudden death.
2. Acceptable
For young people or individuals with good physical health and no underlying medical conditions, running on an empty stomach in the morning is generally acceptable. Such exercise not only helps strengthen the body and increase lung capacity but also burns energy and promotes fat metabolism, aiding in weight loss. Moreover, morning runs on an empty stomach can improve blood circulation, boost immunity, and enhance overall resistance to disease.
