Urgent need to urinate every morning

When we wake up in the morning, the first thing we usually do is to run to the toilet to pee. This is actually a very normal physiological phenomenon. This is because the bladder in the human body must have stored a lot of urine after a night, and it needs to be emptied in time in the morning. Especially some people have the habit of drinking water before going to bed at night, so they will be eager to urinate after waking up in the morning. Therefore, if you simply experience urinary urgency in the morning, there is no need to worry.

1. How much urine can the human bladder store?

When the urine volume in the bladder reaches 100-150 ml, the bladder will feel full. When the urine volume reaches 150-250 ml, the urge to urinate will occur. When the urine volume reaches 250-450 ml, the nerve action causes the contraction of the bladder detrusor muscle and the urine can be discharged from the body.

two. What is the real "holding urine"

People often easily ignore or forget the feeling of a slight urge to urinate until the bladder is almost full, at which point the urge to urinate becomes stronger. In other words, a normal adult should urinate at least 200 ml each time, and 300 ml of urine is considered normal. If the environment does not allow going to the toilet, it is possible to hold urine even if it is more than 400 ml. This is considered true "holding urine".

3. Is it good to drink water before going to bed at night?

1. Many people like to drink a glass of water before going to bed. Some people say that drinking water before going to bed will increase the burden on the kidneys and increase the number of times you get up at night; but if you don’t drink water before going to bed, it will increase blood viscosity and easily induce cardiovascular events. In this regard, kidney experts and cardiovascular experts pointed out that there is no need to worry too much about drinking water before going to bed. For most people, there is no harm in drinking water before going to bed. The key is to drink water in moderation.

2. For patients with severe renal failure and those undergoing dialysis treatment, drinking a lot of water will increase the water load in the body due to the kidney's dysfunctional function in regulating water, which may cause edema and even induce heart failure. In addition, people with poor heart function are also at risk of heart failure if they drink too much water before going to bed. Drinking a lot of water before going to bed will increase the number of times they get up at night and affect their sleep.

3. For the general population, drinking a moderate amount of water before going to bed will not increase the burden on the kidneys, especially in the hot summer when the body loses water quickly, so it is important to stay hydrated. For people with urinary tract infections, drinking more water and urinating can also help flush out urethral bacteria.

4. Sweating during deep sleep causes a decrease in the water content of the blood. For cardiovascular patients, the viscosity of the blood increases. Drinking a glass of water before going to bed can dilute blood viscosity and reduce the risk of sudden events such as myocardial infarction, angina pectoris, and cerebral thrombosis. For diabetics, maintaining a certain amount of water is also helpful in controlling blood sugar.

5. There is no harm in drinking water before going to bed, the key is to drink in moderation. If you are worried that getting up at night will affect your sleep, drink small amounts of water several times during the day, 100 ml each time, to maintain hydration in your body. Drink water in moderation at night, and drink half a glass of water before going to bed to relieve dry mouth. Cardiovascular patients can keep a glass of water at their bedside and drink it when they wake up or get up at night to reduce blood viscosity.
