Filtered water: The safest and most effective choice
Although there are many types of morning drinks, filtered water (boiled and cooled water) is still a suitable choice for most people. This is a natural water source, after boiling it removes most harmful microorganisms, while still retaining a quantity of minerals such as calcium and magnesium.
Filtered water does not contain energy (no protein, fat or carbohydrates), but helps rehydrate the body quickly, reduces blood thickness and supports the excretion process. Drinking a glass of water in the morning also helps the body eliminate metabolites accumulated overnight, without affecting the feeling of breakfast.
Thin salt water: Only suitable for some cases
Thin salt water is boiled and cooled water mixed with a very small amount of salt, almost without a salty taste. This type of water can stimulate intestinal peristaltism, supporting the improvement of constipation in some people.
However, do not mix too salty because it can cause dehydration and make the body more thirsty. In particular, people with high blood pressure, diabetes (diabetes), cardiovascular disease, cerebrovascular disease or impaired kidney function should not drink diluted salt water on an empty stomach in the morning. The reason is that blood pressure usually rises in the morning, supplementing with salt can make this condition more serious.
Lemon juice: Popular but needs to be used reasonably
Lemon juice is usually made from warm water and a small amount of lemon juice, which helps supplement vitamin C and citric acid. These ingredients can stimulate digestion, increase gastric juice secretion and support a better appetite.
However, do not abuse it. Drinking lemon water regularly at high concentrations can increase stomach acid secretion, causing discomfort to the digestive system and affecting calcium absorption. People with stomach problems, especially stomach ulcers - duodenal ulcers, need to be careful when using it.
