We tend to drink more water in summer. Not only does it help prevent dehydration, but it also helps regulate body temperature, maintain a healthy skin, promote gut health, and reduce the risk of kidney stones. But given that the hot weather urges us to drink more fluids, it also lures us towards chilled, refrigerated water. Our elders often tell us to avoid drinking straight from the fridge, claiming it can make us fall sick. But how much of it is true? We spoke to Dr Joydeep Ghosh, Consultant-Internal Medicine, Fortis Hospital, Anandapur, Kolkata, to get some answers and to know whether drinking cold water is safe or not?

Is Drinking Refrigerated Water Safe?
According to an old 1978 study published in the Chest Journal, drinking cold water was linked to the thickening of the nasal mucous. Another study published in Sage Journals found that drinking cold water leads to headaches related to active migraine. However, there isn’t enough evidence to support the claims.
“In general, drinking cold water from a refrigerator is safe for most people,” Dr Ghosh said. According to him, refrigeration helps to keep water at a cooler temperature, which can make it more refreshing to drink. As long as the water is from a clean and safe source, refrigerating it does not pose any additional health risks. It can help to cool down the body temperature, especially in hot weather.
However, the doctor warns against a few potential health issues that may be associated with drinking refrigerated water.
Possible Health Risks Of Drinking Chilled Water
While drinking cold, refrigerated water is generally safe, it can contribute to certain health risks. These include:
Digestive issues
According to Dr Ghosh, some individuals may experience digestive discomfort or bloating when they consume very cold water, especially when it is consumed quickly. “Cold water can temporarily slow down the digestion process, making it harder for the body to break down food efficiently,” he added.
Tooth sensitivity
Cold water can exacerbate tooth sensitivity, particularly in individuals with sensitive teeth or dental issues. Sensitive teeth may become more painful or uncomfortable when exposed to very cold temperatures, the doctor said.
Decreased hydration rate
Some people find it more difficult to drink larger quantities of cold water compared to room temperature water. If you struggle to consume enough water due to the temperature, it could potentially impact your overall hydration levels.

Constriction of blood vessels
In addition, Dr Ghosh said, “Drinking very cold water may cause temporary constriction of blood vessels in the digestive system. This construction could slightly reduce the absorption of nutrients from the food you consume along with the cold water.”
Throat discomfort
Lastly, cold water can sometimes lead to a temporary tightening or discomfort in the throat, particularly for individuals with sensitivity or existing throat conditions, the doctor said.
Bottomline
Whether it is safe to drink cold water or not may be subject to an individual’s body and their overall health condition. Dr Ghosh says to note that these potential disadvantages are generally minor and may vary from person to person. “If one does not experience any discomfort or negative effects, there is no significant risk in drinking cold refrigerated water,” he concluded.
