Water Issues: When to Drink Hot and Cold Water
Does the temperature of the water matter at all?
Arnav Sarkar. Not really. It's far more important that you get enough water throughout the day rather than worry too much about hot or cold.
Neelanjana Singh. Yes, the temperature of water can play a role in refreshing a person depending on the environmental conditions. Warm water/ fluids, however, provide a feeling of satiety and fullness.
