One of the most perennially debated topics in health circles is whether or not it's bad to shower after eating. Often, we're told that it can harm our health but is there any scientific evidence to back this up? This article aims to give a researched and balanced view on this topic.
Why This Belief Exists
The common belief is that 'showering after eating' leads to diverting excessive blood flow towards the skin for the purpose of heat dissipation, thereby reducing the amount of blood available for digestion. However, does this belief hold up under scrutiny?
Debunking the Myth
In fact, while it's true that after eating, our body increases blood flow to the digestive tract for efficient digestion and nutrient absorption, showering doesnât create a substantial enough shift in blood distribution to affect this process.
A study published in the Journal of Applied Physiology found that a full meal resulted in a 24% increase in splanchnic blood flow (the circulation to the organs in our digestive system). Showering, on the other hand, only increases our cutaneous blood flow (circulation to the skin) by a minuscule 7.7%, most of which is localized to the skin surface.
Understanding the Body's Autoregulation
The essence of autoregulationâthe bodyâs ability to adjust blood circulationâcan help us grasp why showering after eating isn't harmful. Your body is perfectly equipped to handle multiple tasks simultaneously, including digestion and thermoregulation. The minor variation in blood flow caused by a shower is unlikely to have any significant impact on digestion.
Timing: An Important Element
That being said, timing may still play a role in how you feel post-shower and eating. Immediately taking a hot shower after a particularly large or heavy meal might cause some people to experience light dizziness or nausea. This is because both digestion and a hot shower can lower your blood pressure, which, for some people, may cause discomfort. However, this is individual and not a hard and fast rule.
Take Home Message
There is no scientific evidence to suggest that showering after eating is bad for your health. In fact, a post-meal shower could even be relaxing and assist in stress reduction, which has been shown to improve digestion. Listening to your body and personal comfort should be paramount in this decision-making process.
Remember, each of us differs in our digestive processes and health profiles, so what is good for one person might not be ideal for another. Communicate with your doctor or a health professional if you're concerned about any symptoms you experience following a meal or a shower.
