During hot summer days, a glass of iced water or iced lemon tea is often a preferred choice. However, many rumors suggest that cold drinks harm digestion and nutrient absorption. Experts affirm: These concerns are overly exaggerated.
"Cold drinks and ice are receiving an undeserved 'bad rap'," Diane Lindsay - Adler, a nutritionist and associate professor of pediatrics at New York University School of Medicine, shared with Popular Science. So, should we clear our ice trays and only drink warm water? Here are the facts you need to know.
When to exercise caution
Whether drinking iced water poses risks depends on an individual's health condition. Doctor Natasha Bhuyan, a family physician in Arizona, stated:
Individuals with acid reflux: Cold drinks can trigger symptoms. However, the type of drink is more important than its temperature. Carbonated beverages, citrus juices, coffee, and alcohol are the primary culprits that worsen reflux.
Individuals with a cold or nasal congestion: A study indicates that cold water slows mucus movement, making nasal fluid expulsion less effective than sipping hot tea or soup.
Individuals with migraines or temperature-induced asthma: If your pain or asthma attacks are exacerbated by cold, iced drinks may worsen symptoms.
Individuals with achalasia: This is a condition where esophageal nerves are damaged, making swallowing difficult. According to a 2012 study, cold drinks can cause chest pain and regurgitation in these patients.
Additionally, issues like sensitive teeth or "brain freeze" (sudden head pain from drinking cold beverages quickly) can occur. If you experience these conditions, room-temperature water is the best option.

The truth about digestion and nutrient absorption
Contrary to rumors, water temperature does not affect digestion or nutrient absorption. Our bodies process liquids quickly; water absorption occurs in about 5 minutes.
Doctor Samuel Choudhury (Singapore) explained: "Cold drinks quickly reach body temperature once consumed. Therefore, any effects (if present) are temporary and do not impact metabolism."
Unexpected benefits of cold drinks
In some cases, cold water offers advantages, especially for athletes or those engaged in intense exercise.
During strenuous activity or exercise in hot weather, the body's temperature rises, leading to a risk of heat exhaustion. Associate Professor of Nutrition Allison Miner (George Mason University) stated that cold water helps lower body temperature faster than warm water.
"If you are a marathon runner or play basketball for 3 hours, cold drinks are what you truly need," Miner emphasized.
Furthermore, if cold water encourages you to enjoy and drink more water during summer, that is a valid reason to use ice. Maintaining adequate hydration is most important, regardless of temperature.
Expert Lindsay - Adler concluded that in summer, people naturally drink more if the water is cold. In winter, warm drinks seem more appealing when thirst is diminished. No option is metabolically superior - the best choice is whatever helps you drink the necessary amount of water daily.
