Tonight as I was walking from my car into the supermarket, I suddenly felt like I desperately had to urinate, and rushed into the supermarket to find the restroom.
This is far from the first time being out in the cold had brought about a desperate urge to urinate, and I thought maybe I should ask this group why that is, and if it’s normal for adults, adult men, older men, or if it’s just me somehow….

The increased production of urine and stimulation of the bladder’s nerve receptors due to constriction of blood vessels and increased blood pressure in the kidneys is the reason why you may feel the need to urinate more frequently in cold weather.
When it is cold outside, your body naturally tries to keep itself warm by constricting blood vessels in your skin and extremities. This constriction of blood vessels helps to decrease the amount of blood flow to the skin and extremities, which helps to conserve heat in the body’s core.
However, this constriction of blood vessels can also cause an increase in blood pressure in the kidneys. The kidneys are responsible for filtering waste products and excess fluids from the blood, and when the blood pressure in the kidneys increases, they are forced to work harder to filter the blood.
As a result, the kidneys produce more urine in order to remove the excess fluids and waste products from the body. This increased production of urine can cause you to feel the urge to urinate more frequently, especially when it is cold outside.
Additionally, cold weather can also stimulate the nerve receptors in your bladder, which can also contribute to the feeling of needing to urinate more frequently.
