When is the best time for the elderly to drink water?

　　before going to bed

　　According to expert research, elderly Not drinking water before going to bed at night can lead to plasma concentration, increased blood viscosity and increased platelet aggregation ability, which can promote thrombosis in the body. For the elderly or those suffering from cardiovascular and cerebrovascular ischemia disease People who drink a glass of water before going to bed at night can prevent fatal infarction. Many elderly people are not used to drinking water before going to bed and are afraid of getting up at night to urinate. In fact, the elderly have bladder atrophy and reduced capacity, so they still have to get up to urinate even if they don't drink water.

　　Due to the reduced contractile function of the kidneys, the elderly urinate more at night, which leads to a lack of water in the body, easily making the blood flow thicker, increasing the resistance to cardiovascular and cerebral blood flow, and easily causing cardiovascular and cerebrovascular diseases. For the elderly with cardiovascular and cerebrovascular diseases, due to changes in the lining of blood vessels and high blood viscosity, they are prone to ischemic stroke. Lack of water at night increases this risk. Therefore, drinking water in the middle of the night is very important.

　　after getting up

　　When the elderly sleep at night, their bodies are relatively dehydrated due to urination, sweating, and breathing, resulting in blood concentration, slow blood flow, and accumulation of body metabolites. Drinking a glass of water after getting up can promote normal blood circulation and prevent high blood pressure, cerebral thrombosis, myocardial infarction and other diseases. It is more beneficial to run after drinking water. Water can keep the gastrointestinal tract clean, help detoxify the liver, improve kidney and endocrine functions, improve immune function, and prevent cold , strep throat, arthritis and certain skin disease。
