What is nocturia?

Nocturia is a condition in which
you wake up more than once at night with the urge to urinate while you are asleep.

Medically,

  • 0 times: No problem
  • Once: Often depending on age
  • More than 2 times: Quality of life is likely to be affected

It is considered.


What is a sleep disorder?

Sleep disorders are

  • Difficulty sleeping
  • Wake up many times during the night
  • I wake up early in the morning
  • I don’t feel like I slept

This refers to a condition that persists and
disturbs daytime life.

Nocturnal urination is said to be particularly closely related to this “type of sleep disorder that causes you to wake up in the middle of the night.”


How are nocturnal urination and sleep disorders connected?

✔ ① If you don’t get enough sleep, you’ll be more likely to wake up with the urge to urinate

Normally during deep sleep

  • Hard to feel the urge to urinate
  • Does not wake up with some stimulation

  • Go to the toilet
  • Unable to fall back asleep

If this trend continues,
the quality of your sleep will significantly decrease.

Especially as you get older,

  • It takes a long time to fall asleep again
  • Sleep becomes shallow

As a result,
nocturnal urination can easily lead to sleep disorders.


✔ ③ Relationship between antidiuretic hormone and sleep

At night,
antidiuretic hormone is normally secreted,
reducing the amount of urine.

However,

  • Low sleep
  • Many late night owls
  • Sleep rhythm is disrupted

This hormone secretion may not work properly,
and the amount of urine may increase at night.

If you have any of the following characteristics,
The main cause may be on your sleeping side.

improving your sleep environment and lifestyle rhythm
is more important than “bladder problems.”
