Avoid Taking a Shower because taking a shower or bath after eating supper might disrupt the digestive process. Digestion requires a lot of energy and blood flow to the stomach. When you take a bath or shower right after eating dinner, your body temperature lowers somewhat.
This is based on science. So, after eating, your blood pump to your stomach to digest that meal. It’s known as blood redistribution. That is why you feel tired after eating, because some of the cerebral circulation is also transfer to the digestive tract. When you take a bath after eating, blood flows to the periphery, such as the skin and subcutaneous tissues. As a result, your digestion will be disrupt, and you will feel bloated. I hope you got your point through. That is why, after eating, we sit in vajrasana to decrease blood supply from the lower limbs and increase it in the digestive system.
“Khane ke baad nahate hai.” Have you ever heard your elders say these things to you? And, indeed, you’ve questioned the veracity of the knowledge passed down to you!
Is there any truth to this, and should one truly avoid taking a shower or bath after eating?
The solution to this question is straightforward. Not so much the explanation!
Let’s begin by examining the physiological reaction to eating and bathing.
Your body begins digesting the moment you put food in your mouth. It transfers blood flow to your digestive system, which includes your stomach, intestines, and other organs. This process is repeated until the food is digested completely, which might take anywhere from 30 minutes to several hours.
Similarly, when you take a hot, steamy shower, your body undergoes “hyperthermic activity.” This indicates that your body temperature is rising, which can be unpleasant. Concurrently, the blood arteries under your skin dilate, and blood flow is rerouted to your skin.
So, theoretically, combining the two acts and jumping into the shower shortly after eating a meal causes your body parts to compete for oxygen or increased blood flow. Jumping into the shower immediately after eating a meal may inhibit digestion and cause feelings of “heaviness,” “bloating,” “sluggishness,” and other unpleasant sensations. And who wants to be uncomfortable because their meal is lying in their stomach undigested?
To be honest, this would be dependent on “what” you ate. If you ate a banana and then took a shower, you would not feel lethargic. However, if you had an aloo paratha (or two, because let’s face it, no one can finish at one), you may.
Having stated that, while this theory makes theoretical sense, this area requires suitable study. Perhaps because no major company stands to gain from supporting such a study (wink wink). If you really must shower after eating, consider taking a cold shower instead. This will improve your metabolism while without significantly redirecting flood flow. Win-win situation? Yes, please!
