Health research and expert guidance have highlighted the relationship between beverage temperature and physical wellness. Experts recommend morning hydration, specifically consuming 225 to 450 ml of water upon waking, to replenish fluids and support concentration and digestion.

Concurrently, studies published in the International Journal of Cancer have identified a significant health risk associated with very hot beverages. Research involving nearly one million adults in the United Kingdom suggests that consuming drinks at excessively high temperatures can more than triple the relative risk of esophageal squamous cell carcinoma. This increased risk is attributed to repeated heat exposure to the esophageal mucosa rather than the specific contents of the beverage.
