There is a saying in TCM health care that "drink salt water early and honey late".

Traditional Chinese medicine believes that salt has the functions of clearing heat, cooling blood and detoxifying. According to Compendium of Materia Medica, salt can "harmonize viscera, eliminate lodging and make people strong". Therefore, drinking a cup of light salt water on an empty stomach after getting up in the morning is conducive to reducing fire and benefiting the kidney, keeping the stool unobstructed and improving the digestion and absorption function of the stomach.

When doing a lot of exercise or sweating, it is suitable to drink light salt water, because it can replenish the salt lost by the body. Drink this in moderation. If the daily intake of salt is too large, it will do harm to the body.
