Myth or Truth - Stop Drinking Before Bed?

A healthy and undisturbed sleep is essential for health. The body needs physical and psychological regeneration in order to repair damaged cells or to recover from the day's events. Anyone who wakes up at night because the bladder has answered not only has to get up to go to the toilet, but may also have problems finding their way back to sleep afterwards. It is therefore widely said that one should not drink anything before going to bed. But is that really true?

Drink less to reduce the urge to urinate?

Depending on the time of year and physical activity, every adult should drink at least two to three liters of fluid throughout the day so that there is no lack of water or undersupply. Although you can reduce the urge to urinate by consciously reducing your fluid intake, there are then far-reaching health risks. For example, you can lose your healthy feeling of thirst and, moreover, damage your entire organism. Other possible consequences include:

  • dry skin and mucous membranes
  • a headache
  • fatigue
  • Indigestion
  • dizziness
  • Heart trouble

Harmless reasons for an urge to urinate at night

If you ingest the minimum recommended amount of two to three liters through food and drink throughout the day, you should not wake up with a full bladder at night. Otherwise, the following could be responsible for this:

Unusually high fluid intake

If you drink disproportionately much in the evening, it can easily happen that you are not spared going to the bathroom. Drinks with a high sugar content are particularly irritating to the bladder.


Although many people swear by an after-work beer or enjoy a glass of wine because they can fall asleep better, the night can sometimes be restless. On the one hand, alcohol increases the urge to urinate; on the other hand, it has a negative impact on sleep behavior. The breakdown of alcohol disrupts the flow of sleep phases. You should therefore have the last alcoholic drink around four to six hours before going to bed.


Similar to alcohol, caffeine has an adverse effect on urination and sleep. In addition to the urge to urinate, it stimulates the activity of the nerves. Caffeine is not only found in coffee, but also in green and black tea, cola, energy drinks and in some pain relievers. You should therefore stop taking caffeinated drinks and substances after 4 p.m., at least four hours before going to bed.


The hormonal changes caused by pregnancy can increase the urge to urinate at night. The growing child also takes up more and more space and can therefore press on the bladder. These are normal side effects of pregnancy and nothing to worry about.

Bladder weakness and menopause

A harmless weakness of the bladder can be the cause of the nocturnal and general urge to urinate. However, you can train a weak bladder by going to the toilet at fixed times and strengthening your pelvic floor with exercises (see also “Pelvic floor exercises and pregnancy gymnastics”). Try to wait at the first urge to urinate and not to empty your bladder immediately.

In addition, the declining production of estrogen during menopause can lead to bladder weakness. In this case, too, special exercises can strengthen the muscles of the pelvic floor and thus alleviate discomfort.

Nocturia: Nocturnal urge to urinate as a warning

Urinating several times at night (medical: nocturia) can be a warning. The following causes can be present:

Nocturnal polyuria

Normally two thirds of the urine is produced during the day and one third at night. Nocturnal polyuria is when more than a third of the urine is produced during the night. Much more fluid has to be excreted than usual.


Cystitis is accompanied by a frequent need to urinate. It is usually associated with severe pain and burning sensation, especially when urinating.

Signs of cardiovascular disease

In this case, the body does not transport the blood sufficiently during the day, as a result of which water from the blood gets into the tissue. By lying down at night, the heart is relieved, the blood flow improves and the water is removed from the tissue. The bladder fills and the result is an urge to urinate at night.

Diabetes mellitus

Badly controlled diabetes mellitus can also be the reason for going to the toilet regularly. It is advisable to have your blood sugar level checked. It could also be that you do not know anything about an existing diabetes, which is why you should also have your blood sugar level checked.


In men, an enlarged prostate (also called the prostate gland) can narrow the urethra. This increases the likelihood of residual urine being left in the bladder, which increases the risk of cystitis. This can lead to a vicious circle of nocturnal urges to urinate.

Drink the right thing before bed, but not too much

From a medical point of view, nothing speaks against drinking before bed and still sleeping through the night. Be careful not to drink too much for no reason. The choice of drink is no less important. You should avoid alcohol and sugary foods and instead have a soothing tea or water. Drinking continuously throughout the day is much more important. So your body has enough fluids.
