Is there a disadvantage in washing glans with cold water

If the temperature is too high recently, the normal population occasionally uses cold water to clean the glans, which helps to clean the foreskin, keep the local skin clean and dry, reduce the risk of eczema, balanitis and other diseases. At this time, there is usually no harm. If the temperature is too low recently, the normal population frequently uses cold water to clean the glans, which may stimulate severe contraction of local blood vessels, causing blood reflux disorders in some tissues, and easily induce local pain.
