Why do you sometimes shiver when you wee? Asked by John Rae of Clapham, United Kingdom
Shiver wee? This is not to be confused with chivalry (the valorous qualities of a knight or gentleman) or a shivaree (a noisy mock serenade by friends of a newly wed couple). This is a surprisingly commonly-asked Odd Body Question (OBQ), and no research has been done on this topic. Low room temperature as covered parts of the body are exposed could be an obvious cause. More seriously, the shivering is an example of the human body\’s autonomic nervous system (ANS) at work. We are not conscious of the ANS. It runs on automatic, hence its name, \”autonomic\”, which literally means \”self controlling, working independently\”. The urination reflex is relayed through the ANS. The reflex is directly related in strength to the amount of stretch of the bladder. Thus, the degree of shivering is generally related to how full the bladder is at the time of urination. The ANS has two divisions. One is the parasympathetic nervous system (PNS) and the other is the sympathetic nervous system (SNS). The SNS tends to keep the bladder relaxed and the urethral sphincter contracted.
This is why one does not have an \”accident\” while one is concentrating on something else. It is true to say that the more \”desperate\” one becomes in response to a bulging bladder, the more the SNS acts to keep you dry. The SNS response includes the release by the brain of chemicals doadrenal medulla catacholamines epinephrine, norepinephrine, and dopamine to bring about the necessary body reactions. When the opportunity arises to allow the parasympathetic side of the ANS to take over, the change in catacholamine production probably causes of the shivering. Laboratory experiments which have not been undertaken would prove this beyond doubt. In any case, at the moment of urination, there is a slight blood pressure rise and a momentary flushing or euphoria shortly after relaxing the urethral sphincter. Some find this feeling pleasurable. At such moments, some people say \”ah\”. This same response in its most extreme forms causes fainting. All of this is the ANS doing its job. Stephen Juan, Ph.

Email your Odd Body questions to Humans display all kinds of weird habits and behaviors that, if you take a moment to think about them, make no sense at all. For example, despite knowing that it won t do us any good (but, it does somehow! ). Another strange behavioral quirk is when we start to wriggle, squirm, and stamp our feet, which may look like aPdance move to an onlooker, when in fact we simply have an urgent need to urinate. We know that this dancing won t do us any good, so why do we do it? is, without a doubt, a vital function of the human body. It is one of the fewPways we are able to excrete excess or waste materials from our body. For those who don t know, urine is produced in the kidneys during the process of blood filtration. The waste materials present in the blood form a major part of our urine. It is then passed on to the bladder through the ureters, where it is stored untilPyou get up and pee. The longer you hold in the urine, the more pressure your bladder experiences as it continually urges you to relieve itself of the pressure, as this is where all the action takes place!
When the bladder is full, an uncomfortable feeling of urgency is created in your mind. However, if there is no way for you to pee (in other words, relieve your bladder), you realize that you are going to have to hold it a little longer. This conflict triggers a number of rhythmic displacement behaviors, and the act of dancing is one of them. Why Does it Happen? (or activities) occur when the body is faced with an external stimulus that makes you feel like performing two activities that are completely contradictory to each other. This happens in animals too. Take the example of a squirrel; when you try to offer it a peanut, it finds itself in two contradicting situations. It badly wants to have that peanut, but also knows that going near a human is too large a risk. Humans similarly show displacement behavior in some situations. For example, people scratch their heads or bite their nails when faced with a difficult situation or problem. These types of activities don t directly help you solve the problem or provide you with a solution, but it s the way your mind tries to divert your attention from the conflict by engaging in seemingly meaningless activities.
There are a number of ways that people behave when they suppress a strong urge to pee. These include tapping their feet, drumming their fingers, pacing up and down, or humming (to take your mind off it). These are the signs that commonly appear when a person holds in a relatively weaker urge to urinate. However, when you haven t urinated in a while (and your bladder is completely full), you might hop from one foot to another, clench and unclench your muscles, and wriggle and squirm. The most interesting part about this is that you know that staying calm will help you last longer! It s not a good idea to hold in urine for extended periods of time. Therefore, if you can, urinate when your body tells you to and relieve your aching bladder of the pressure building up. Moreover, peeing after a long time is really relaxing. It sPno surprise that some people believe that relieving themselves after a long wait is the best feeling in the world! It certainly feels incredible in the moment!
