Wake up in the morning, dry mouth, at this time, drink water can not only quench your thirst, but also can make you full of energy, as soon as possible to work and life. So, what water do we drink in the morning is good for the body? Choice 1: plain water. Drinking plain water in the morning is the best choice, because it does not contain any heat, just get up, the gastrointestinal tract is still in the process of “dormancy” into the “recovery”, at this time, if you drink water containing calories, will increase the burden on the gastrointestinal tract, long-term, the Gastrointestinal function will be disrupted, thus affecting the absorption of nutrients in the gastrointestinal tract during the morning meal, indirectly affecting the mental state throughout the day. The temperature of plain water should be appropriate, too cold or too hot on the gastrointestinal tract stimulation are large. Choice 2: lemon water. The main component of lemon water is vitamin C, but also includes VB1, VB2, etc. The vitamin is easily absorbed, less irritating to the gastrointestinal tract, and is a big help to friends with long-term constipation, which can improve the difficult problem of defecation. In addition, it is also the breakfast “appetizer soup”, can promote appetite and improve digestive function, it is recommended that constipated friends can try to drink, but need to be reminded that because acidic food has some damage to the teeth, so drink lemon water to rinse your mouth as soon as possible. Choice 3: Honey water. Honey is a nutritious natural nourishing food and is one of the most commonly used tonic for the elderly. The main components of honey are glucose and fructose, which are easily absorbed, and honey water has a laxative effect, especially in the morning before breakfast, the effect is better. The first glass of water in the morning can not drink what? 1, cola and other carbonated beverages: get up early in the morning to drink carbonated beverages directly, the idea that you need to supplement calories after waking up is incorrect, because most carbonated beverages contain citric acid, in the metabolism will accelerate the excretion of calcium, reduce the content of calcium in the blood, long-term drinking will lead to calcium deficiency and nutritional imbalance. 2, light salt water: morning thirst is a lack of water, drink light salt water after waking up, will increase the salt in the body, not only can not relieve thirst, but also aggravate the phenomenon of dehydration, people more dry mouth. In addition, drinking salt water in the morning will make the blood pressure higher, which is even more dangerous for patients with high blood pressure. 3, tea: after waking up will drink tea on an empty stomach, which is a bad habit. No food in the stomach and intestines, tea straight into the stomach, as if “to attract wolves into the room”, the ancients said “fasting tea people panic”, especially when drinking strong tea on an empty stomach, because of the high content of caffeine in tea, will accelerate the heart rate and cause panic, to the detriment of the body.
