The urinary bladder is a very integral part of your body system. It holds urine until it is time for it to eliminate. It is normal for you to have the urge to urinate everytime you take in copious amounts of liquids. You may even notice a frequency in your urination when the weather is cold. The reason behind this is because you donâ€™t perspire when it is cold. So, your body needs to eliminate excess fluids and electrolytes through urination.
