I noticed a strange phenomenon: when it is cold, I keep peeing. Maybe because of the cold? And why?
Already, we must understand where the urine comes from. OK, there is the bladder but it can be thought of as a storage bag that has to be emptied when full. No, urine comes from the kidneys. These are essential organs whose role, among others:
- to cleanse the blood of toxic waste (urea, creatine, etc.)
- to balance the presence of certain elements that the body needs.
- to maintain the right amount of water in the body.
In short, the kidneys reject what is superfluous: water and excess minerals (potassium, sodium, calcium…) as well as toxins. This all forms urine which will be transported to the bladder via the ureters.
- In other words, the kidneys are filters of blood.
- However, we have 4 to 6 liters of it in the body, and every day, about 1,500 liters of blood pass through the kidneys!
- It is an understatement to say their importance.
- And the cold in all of this? I’m coming.
- We have the ability to maintain our body temperature at 37 ° C,
- whatever the external conditions: we are homeothermic beings.
Most of the heat exchange takes place in the skin and extremities of the limbs. The blood which irrigates them cools on contact with the surrounding environment and carries this cold inside the body.
In summer it is not annoying (on the contrary) but in winter it can be dangerous. To limit these exchanges, a small region of our brain, the hypothalamus, controls the contraction of peripheral blood vessels. But our blood volume is constant.
It must go somewhere else, that is to say to the vital internal organs such as the heart, the brain and… the kidneys to the detriment of the peripheral members (feet, hands, nose, ears…).
The kidneys then filter more blood and send more urine to the bladder, which must empty more often. In short, we pee more when we freeze our noses. This also means that it is better for the child’s room not to be too cold at night otherwise he may want to pee more often.
But you will have to get out of bed and face the cold. Some people prefer to empty themselves in their sheets.
