The debate over whether cold or hot water is healthier is gaining traction, but experts suggest the optimal temperature depends on individual health goals.
While some research indicates cold water may offer a minimal boost to calorie expenditure as the body heats it, the effect is not significant for substantial weight loss. Registered dietitian Tanya Freirich notes that focusing on overall water intake is more crucial for weight management.
For athletes exercising in heat, a cooler water temperature, around 60.8 degrees Fahrenheit, is associated with the least perspiration, aiding efficient rehydration without gastrointestinal distress.
Warm water, on the other hand, is linked to relaxation and improved digestion, potentially accelerating gastric emptying and reducing stress hormone levels. However, very cold water can trigger migraines or digestive discomfort in sensitive individuals.
Ultimately, the most beneficial water temperature is one that encourages consistent hydration, which is vital for overall health.
