The healthiest time to drink water in a day is in the morning. The human body loses about 450 ml of water every night, and it will be in a physiological water shortage state after getting up in the morning. It is best to drink a cup of warm water on an empty stomach before eating, which can quickly dilute the blood and improve dehydration at night. Drink a large glass of lemonade on an empty stomach every morning to detoxify. This method is simple and practical. Lemonade can eliminate harmful substances in the body, whiten the skin, detoxify and clear the intestines, quench thirst and dilute appetite, killing two birds with one stone, without special dieting. So how do we make lemonade? The method is to slice the lemon and soak it in water, preferably with warm water, which is beneficial to preserve more nutrients in the lemon. Of course, you can also add lemon slices when drinking black tea and drinks. Lemonade contains lemon rich in vitamin C, which is a catalyst to promote defecation. Drinking homemade lemonade on an empty stomach in the morning can solve the pain of constipation. Citric acid, which is unique to lemon, can decompose pigment particles accumulated under the skin and strengthen the vitality and resistance of blood vessels.
