Get up early in the morning, some people are used to drinking a cup of boiled water, some people are used to drinking a cup of light salt water, and some people are used to drinking a cup of honey water. What is the best water to drink? Boiling water has the function of clearing intestines; Honey water has the functions of protecting blood vessels, relaxing bowels, lowering blood pressure, diminishing inflammation, promoting wound healing, improving liver function and strengthening body. Light salt water can clean the stomach and improve habitual constipation. Science shows that, by contrast, it is more scientific to get up and drink a cup of honey water in the morning. After a night's sleep, most of the water in the body has been discharged or absorbed. At this time, drinking a cup of honey water on an empty stomach can not only replenish water, but also increase nutrition, which can completely replace the status of boiled water. Moreover, light salt water is not conducive to health care, because under normal circumstances, sodium in the human body will not be lacking, and excessive intake may lead to or aggravate diseases such as hypertension and nephritis. Doctors suggest that after heavy physical labor or strenuous exercise, when excessive sweating leads to the loss of sodium salt, you should drink appropriate amount of light salt water to supplement water and electrolytes.
