Why do we need to go to the bathroom during the night?

Equals a good night sleep

Have you ever wondered why you’re getting up to go to the toilet in the middle of the night whilst your partner is nicely tucked up in bed for the ENTIRE NIGHT? Well there’s a reason for this and we’re going to break it down so that it’s easy to understand and may even help you get a better night sleep.

Our bodies have a hormone called Aldosterone which is part of the Renin-Angiotensin System. Aldosterone is secreted by the cortex of the adrenal glands and its job is to help the body retain sodium by increasing the amount that our kidneys reabsorb. Sodium pulls water in the direction that it’s headed so aldosterone helps to conserve body water.

Aldosterone is released in response to:

Low blood Volume and/ or; Low Blood Pressure and/ or; High Potassium in Extracellular Fluid

These are all a sign that our body requires more fluid.

This is where it gets interesting! Aldosterone pulsates, releasing small bursts of the hormone into the system. Our body goes in and out of deep sleep but once in the deep sleep zone, our body releases the Aldosterone hormone into the system, suppressing the need to go to the bathroom therefor allowing us to sleep through the night.
