Old people should drink more water? What is the harm of not drinking enough water? How to drink correctly? Answer for you one by one

Many old people think that drinking water is unnecessary, but this is actually wrong. Water is important to any living thing, let alone human beings. If you don't replenish water to your body in time, it will easily lead to dehydration, which will lead to a series of hazards. Therefore, the elderly should drink more water and master the correct drinking methods.

1, physical decline

Most elderly people's body cells have been seriously short of water, but they still don't feel thirsty, which is related to not receiving the signal of water shortage. Under normal circumstances, when the body is short of water, it will increase the osmotic pressure of blood, and the signal of water shortage will be quickly transmitted to the hypothalamic receptor, and people will feel thirsty. However, the elderly are weak in constitution, are not very sensitive to nerve reflex, and cannot suffer from water shortage quickly, which will inevitably make the body short of water, so drink more water.

2. Suffer from illness

Some old people suffer from certain diseases, and their legs and feet are inconvenient, not to mention drinking water and pouring water. There are also some elderly people who don't want to drink water because it's too much trouble to go out and find a toilet. In addition, some elderly men have frequent nocturia and refuse to drink water, fearing that drinking water will affect the quality of sleep and dehydrate their bodies.

3. The weather is very cold

When the weather gets cold, it will slow down the metabolism and the demand for water will inevitably decrease. Some elderly people don't have the consciousness of drinking water actively, which leads to myocardial infarction.

4. Eating habits

Old people in the south like to drink all kinds of soups, so they can get enough water from their diet. Usually, they are not short of water. However, the elderly in the northern region have a dry diet and drink less water, which easily leads to water shortage.

Insufficient drinking water for the elderly will cause excessive dehydration, lower blood pressure and slow blood circulation. Especially in patients with cardiovascular and cerebrovascular diseases, dehydration will make the brain and heart ischemic, thus causing myocardial infarction or cerebral infarction. When the body is short of water, metabolic waste and garbage can not be discharged in time, which is easy to produce stones and lead to gout or kidney disease. Insufficient drinking water for the elderly will also cause constipation, reduced skin moisture and worse skin elasticity. Also, when drinking insufficient water, the secretion of tears and saliva will be reduced, which will affect oral health, and at the same time, the lubrication of the eyes will be reduced, which will easily aggravate presbyopia and dry eye.

In addition to getting water from diet, it is necessary to supplement 1000~ 1500 ml of water, but this is not absolute and varies from person to person. If the elderly are accompanied by heart and kidney diseases, it is necessary to limit the amount of drinking water. If there is a lot of exercise, before and after bathing and fever, it is necessary to increase the amount of drinking water. Drinking time can be arranged before going to bed, after getting up in the morning, before and after bathing, before and after exercise. To develop the habit of taking the initiative to drink water, you should take a sip of water and drink it slowly, because the elderly have poor blood dilution and adjustment ability. If you drink too much water at a time, the blood volume will increase and the electrolyte will be disordered.

skill

When people get old, the composition of the body will change greatly, and the water content will gradually decrease. In addition, when the elderly have dehydration symptoms, it will cause various accidents, so it is necessary to pay attention to frequent hydration. If the elderly don't like drinking boiled water, they can also drink light tea or fruit and vegetable juice appropriately. Drink plenty of water, but don't drink too much water when you have heart failure, high blood pressure or kidney disease.
