For many people, drinking a refreshing glass of cold water immediately after a meal seems natural and satisfying. It helps to rinse the meal, cools the body and seems harmless. But is it really as harmless as we think it is? Health experts suggest that drinking icy water right after a meal may have a surprising effect on digestion and overall well-being.
How does digestion work
When we eat, our stomach begins to break down food into smaller molecules using stomach acid and digestive enzymes. The muscles of the stomach convert the food into a semi-liquid form, called food pulp, which then goes into the intestines, where it is absorbed by nutrients. In order for this process to be effective, body temperature and enzyme activity must remain relatively stable.
What does cold water do
When very cold water enters the stomach, it can cause a temporary shock to the digestive system. Here's what might happen:
-
Slower digestion. Low temperatures can cause narrowing of blood vessels in the stomach, which slows down circulation and slows down digestion. Food can stay in the stomach for longer, which in some people can lead to bloating or discomfort.
-
Curing fats
One of the most common claims is that cold water will harden the fats from the meal you just eat. Although the body ultimately heats everything up, this process can make it difficult for the stomach to quickly emulsify fats. As a result, digestion becomes less efficient. -
Additional energy demand.
Your body needs to work harder to restore the cold liquid to body temperature (about 37°C / 98.6°F). This requires energy that could otherwise be used for the digestive process. -
Possible heartburn or discomfort
In some people, a sudden change in temperature can trigger muscle spasms in the digestive tract, which may resemble mild spasms or even stomach reflux.The good news is that drinking cold water is not dangerous for most healthy people. The body is very flexible and over time will compensate for the temperature difference. However, if you often experience bloating, indigestion, or abdominal pain after meals, drinking water at room temperature or warm temperature can help relieve these symptoms.
Healthier alternatives
-
To support digestion, drink warm water or herbal tea after meals
-
If you like cold drinks, wait at least 30 minutes after eating before reaching for water with ice.
-
Try to sip water before meals, not immediately after. This helps to hydrate the body and can even help control body weight.
The Last Thoughts
A glass of icy water after a meal may seem refreshing, but your digestive system may disagree with it. Although drinking it in moderation is not harmful, repeated habits of drinking very cold water just after a meal can make it difficult to digest over time. To facilitate digestion and improve overall comfort, try drinking drinks at room temperature or warm instead. Your stomach will thank you for that.
