How should the elderly drink the first glass of water when they wake up in the morning

1. What to drink

Fresh boiled water is the best choice. Boiled water is natural water that has been boiled through multiple layers of purification. The microorganisms in the water have been killed at high temperatures. The calcium and magnesium in boiled water are very beneficial to your health. Studies have shown that hard water containing calcium, magnesium and other elements can prevent cardiovascular diseases.

Many elderly people think that drinking salt water is good for their health, so they drink salt water when they get up in the morning. This understanding is wrong. Research shows that people drink no water during a whole night's sleep, but breathing, perspiration, and urination are still going on. These physiological activities consume and lose a lot of water.

Drinking some boiled water when you get up in the morning can quickly dilute the blood and correct hypertonic dehydration at night. Drinking salt water will aggravate hypertonic dehydration and make your mouth even drier. What's more, morning is the first peak of human body's blood pressure rise, and drinking salt water will make blood pressure higher.

It is best not to drink juice, cola, soda, coffee, milk and other beverages with the first glass of water in the morning. Most carbonated drinks such as soda and cola contain citric acid, which accelerates the excretion of calcium during metabolism and reduces the calcium content in the blood. Long-term consumption can lead to calcium deficiency. While other drinks have a diuretic effect, drinking them early in the morning will not only fail to effectively replenish the body's lack of water, but will also increase the body's demand for water, causing water shortages in the body.

　2. What temperature

Some elderly people like to drink ice water from the refrigerator after getting up in the morning. They think this is the most refreshing. In fact, it is inappropriate to drink such water in the morning, because the gastrointestinal tract has been emptied at this time. Water that is too cold or too hot will irritate the gastrointestinal tract and cause gastrointestinal discomfort. It is best to drink water in the morning. It is best to drink boiled water with the same room temperature. When the weather is cold, you can drink warm boiled water to minimize gastrointestinal irritation.

Research has found that boiled water cooled to 20-25°C has specific biological activity. It can easily penetrate cell membranes, promote metabolism, and enhance the body's immune function. People who are accustomed to drinking warm or cold water have higher deoxygenase activity in their bodies, better metabolism, less lactic acid accumulation in muscle tissue, and less fatigue. Be sure to cover the boiled water when drying it out the night before, because boiled water will lose activity if exposed to the air for too long.

　3. How much to drink

A healthy person should drink at least 7-8 glasses of water (about 2.5 liters) every day. When exercising heavily or in hot weather, the amount of water consumed should increase accordingly. When you get up in the morning, it is a critical moment for the body to replenish water for the new day. It is best to drink 300 ml of water at this time.

　4. How to drink

Drinking water in the morning must be done on an empty stomach, that is, before breakfast, otherwise the effects of promoting blood circulation and flushing the stomach will not be achieved. It is best to drink water in small sips, because drinking water too fast is very harmful to the body and may cause lowered blood pressure and cerebral edema, leading to headaches, nausea, and vomiting.
