Can drinking a glass of light salt water in the morning detoxify?

Netizen question: I have the habit of drinking water after getting up every morning.

Recently I heard that drinking a glass of light salt water in the morning can help detoxify, relieve constipation, and relieve constipation. I want to know if this is true?

In fact, drinking light salt water in the morning is not recommended because drinking light salt water on an empty stomach not only fails to detoxify and prevent constipation, but may also affect your health.

On the one hand, the morning is the first peak of blood pressure rise, and the blood is already viscous at this time. If you drink light salt water, it may further increase the blood concentration and blood pressure, which will cause physical discomfort.

According to the "Dietary Guidelines for Chinese Residents (2016)", the daily salt intake per person should not exceed 6 grams. Modern people generally have a high salt intake. Drinking light salt water in the morning will invisibly increase unnecessary salt intake and increase the burden on the kidneys.

On the other hand, after the light salt water enters the gastrointestinal tract, it will be quickly absorbed into the blood and eventually excreted through urine, so it has no so-called detoxification effect.

Furthermore, light salt water does not contain dietary fiber, oil or other substances that aid defecation, let alone eliminating constipation.

What's the best first glass of water to drink in the morning?

Compared with tea, milk, coffee, juice, etc., boiled water does not contain sugar or salt, and will not burden the kidneys and cardiovascular system. Therefore, it is recommended to drink a cup of about 200 ml of warm boiled water in the morning.

Of course, constipation patients can also try to drink honey water in the morning. But it should be noted that the honey water drunk in the morning should be brewed with cold or warm water, not boiling water.
