The question of whether cold or warm water is better for health has attracted increasing attention among people seeking healthier lifestyle habits. Experts explain that the effects of water temperature can vary depending on a person’s health condition and overall goals.
Research suggests that water temperature may influence certain bodily processes such as digestion and relaxation, although its impact on weight loss remains relatively small.
Cold water may slightly increase the body's energy expenditure because the body works to warm the water to its normal internal temperature. This process can lead to a minor increase in calorie burning. However, specialists emphasize that the effect is minimal and not enough on its own to produce significant weight loss.
Nutrition experts point out that when it comes to weight management, the most important factor is the amount of water consumed daily rather than its temperature. Increasing daily water intake has been associated with gradual weight reduction in some individuals, particularly when combined with balanced nutrition.
Warm water, on the other hand, is often associated with digestive benefits. Warm fluids can stimulate intestinal activity and help speed up gastric emptying, which may support smoother digestion for some people.
In addition, some studies suggest that warm beverages may help reduce stress levels. Drinking hot drinks may contribute to lowering cortisol levels, a hormone associated with stress, which can promote relaxation after demanding tasks or long working hours.
However, extremely cold water may cause discomfort for certain individuals, especially those with sensitive nerves or digestive conditions such as irritable bowel symptoms. In some cases, it may trigger headaches or a temporary sensation often referred to as “brain freeze.”
Despite these differences, experts agree that water temperature does not affect the body's ability to absorb nutrients. The main recommendation remains maintaining adequate hydration by drinking sufficient water throughout the day.
Health specialists generally recommend consuming around seven to eight glasses of water daily for adults, with adjustments depending on physical activity levels and climate conditions.
