Sleeping the same night, some people wake up until dawn, while others wake up two or three times. For elderly people, frequent waking up not only affects sleep, but also poses a risk of falls.

An interesting phenomenon is that in clinical practice, it has been found that after the weather cools down, many people urinate more at night and wake up more frequently.

How much nocturia is considered excessive? Why is it easier to wake up late in cool weather? What are some ways to reduce the number of nights you wake up? Life Times(Search for "LT0three85" on WeChat to follow)Invite experts to answer your questions one by one.

How much nocturia is considered excessive?

Excessive nocturia has a significant impact on the quality of life, but how to measure 'excessive nocturia'?

Noctururia refers to the condition of having to wake up and urinate at night, and the judgment criteria in relevant consensus are:

(Excluding the last urination before falling asleep and the first urination after waking up in the morning).

However, estimating nocturnal urine volume through frequency is often not accurate enough, and two other standards can be used,As long as either condition is met, it can be considered as increased nocturia:

oneUrinary volume at night is greater than one/four of that during the day or more than 500 milliliters (approximately one bottle of mineral water);

twoThe ratio of nocturnal urine volume (milliliters) to body weight (kilograms) is greater than one0. For example, a person weighing 50 kilograms who produces more than 500 milliliters of urine at night can be considered as having excessive nocturia.

The data shows that the incidence rate of nocturia increases year by year with age. About 70% of the elderly over 65 years old have nocturia problems, while 90% of the elderly over 90 years old have nocturia problems.

Zhang Yong, a professor of urology at Beijing Tiantan Hospital, said that this situation is not considered "nocturnal urination" because you have been in a conscious state, and the speed of urine production is as fast as during the day. The feeling of the bladder is still very sensitive, and it is normal to urinate once in a while, or it may be caused by anxiety.

There is a reason why it's easy to wake up late in cold weather

The human body is in a dynamic balance between the water it replenishes through eating and drinking, as well as the water it loses through sweating, breathing, urination, and other processes.

Less sweating

When the amount of water consumed remains the same, the human body sweats more in summer, but when the weather cools down, the amount of sweating decreases, and bodily fluids are more dependent on being excreted from the body through respiration, urine, and other means.

In autumn and winter, sensitive individuals often feel that nocturia increases and they wake up more frequently.

The nerve excitability is high

We all have an experience where it's easier to go to the bathroom when we're nervous. In autumn and winter, under cold stimulation, nerve tension increases and excitability is high. When subjected to a little stimulation, one feels like urinating, which is a stress response.

In addition, the decomposition and metabolism of fats, glycogen, proteins, and other substances are accelerated, resulting in an increase in endogenous water and, to a certain extent, an increase in urine output.

Occasionally wake up once or twice at night, don't be too nervous. As long as it doesn't fall within the aforementioned criteria for increased nocturia, you can reduce waking up by adjusting your diet and lifestyle.

Identify four potential diseases

In addition to physiological factors, increased nocturia may also be caused by diseases such as urinary tract diseases and cardiovascular diseases.

one

Prostate problems

As men age, they are more likely to develop prostate hyperplasia, squeezing the bladder and urethra, reducing the bladder's urine storage space and increasing the frequency of nocturia, but with less urine output each time.

The most common cause in women is urinary tract infection, often accompanied by frequent urination, urgency, and pain; Some women have bladder overactivity, pelvic floor muscle relaxation, and are also prone to nocturia.

two

kidney disease

The first symptom of glomerular disease, chronic tubulointerstitial disease, hypertensive kidney disease, etc. is increased nocturia, which then develops into renal polyuria.

three

Cardiovascular issues

Cardiac dysfunction causes an increase in blood volume throughout the body, followed by an increase in urine. Hypertensive patients may experience kidney damage due to poor blood pressure control, leading to excessive urine production.

four

Endocrine diseases

Endocrine diseases:

Diabetes, especially when the amount of dinner is large and the blood sugar control is poor;
Hypercalcemia is commonly seen in patients with hyperparathyroidism or multiple myeloma.

Urologists teach you to reduce waking hours

For all populations, adjusting the following lifestyle details can help reduce nocturia and waking up.

Drink less water before bedtime

Eat less salt

Reducing salt intake can significantly reduce the frequency of waking up at night. The latest version of residents' dietary guidelines suggests that adults should control their daily salt intake to less than 5 grams.

Dinner should be particularly light, while controlling seasonings with high sodium content such as soy sauce.

Pay attention to keeping warm at night

Empty the bladder as much as possible before bedtime. Pay attention to keeping warm at night, which can increase skin blood supply and reduce urine production.

Control the primary disease

Actively control diabetes, heart failure, prostatic hyperplasia and other basic diseases, and be alert to urinary infection. For those who take diuretics for a long time, the medication time can be adjusted to evening.
