The navel is the weakest part of the human body to the outside world. In addition, the secretion of gastric acid and digestive juice is reduced in summer, and the ability to resist bacteria is weakened. In air-conditioned places, it is easy to be stimulated by cold and heat, causing gastrointestinal dysfunction, leading to the invasion of pathogenic bacteria, and gastrointestinal diseases such as vomiting, abdominal pain and diarrhea. Eating ginger or drinking ginger soup properly can play a preventive role. Scientists have found that ginger can play the role of some antibiotics, especially against salmonella.

Cold:

Often in an air-conditioned environment, it is easy to feel the outdoor cold because of the large temperature difference between indoor and outdoor. If you can eat a few slices of ginger or drink a bowl of brown sugar ginger soup in time, it will help to dispel cold and relieve exterior syndrome, or soak your feet with ginger soup (adding some salt and vinegar) can also receive good curative effect.

Waist and shoulder pain:

It is hot in summer, and staying in an air-conditioned room for a long time makes the shoulders and back vulnerable to diseases such as wind, cold and humidity, especially the elderly are prone to scapulohumeral periarthritis.

This method can relax muscles from tension, relax muscles, promote blood circulation, and greatly relieve pain.
